We found these three yesterday. The black adder is a melanistic Adder which was born with an increased amount of black pigmentation in the body. These darker forms occur more frequently in adders than they do in the smooth or grass snakes and could have advantages over the normal coloured adders. It's likely their colour offers better camouflage when hunting. Also their bodies warm up faster when basking, although they can also loose heat more quickly.
Laguna Colorada (Red Lagoon) is a shallow salt lake in the southwest of the altiplano of Bolivia, within Eduardo Avaroa Andean Fauna National Reserve and close to the border with Chile.
The lake contains borax islands, whose white color contrasts with the reddish color of its waters, which is caused by red sediments and pigmentation of some algae.
Laguna Colorada is one of the Ramsar Wetlands of International Importance under the Ramsar Convention signed in 1971.
James's Flamingos abound in the area. Also it is possible to find Andean and Chilean flamingos, but in a minor quantity.

We took the backward route from Tupiza northwards to the Reserva Nacional de Fauna Andina Eduardo Avaroa and further to Salar de Uyuni salt plain; snow-covered volcanoes at the horizon line, red-coloured rocks and sand, colorful lagunas, and slow 4WD journey through the land of thin air - that's Bolivia southern part of Altiplano.
Laguna Colorada is most likely the most stunning of the colorful lakes; we spent there a night and thus got a chance for slow silent walks around, admiring its unforgettable stunning beauty...
HUMPBACK WHALES: 2015
COOL FACTS:
•Males sing complex songs on wintering grounds in Hawaii that can last up to 20 minutes and be heard 20 miles (30 km) away!
•In the Pacific, humpbacks migrate seasonally from Alaska to Hawaii--they can complete the 3,000-mile (4,830 km) trip in as few as 36 days!
•Humpback whales are well known for their long pectoral fins, which can be up to 15 feet (4.6 m) in length. Their scientific name, Megaptera novaeangliae, means "big-winged New Englander" as the New England population was the one best known to Europeans. These long fins give them increased maneuverability; they can be used to slow down or even go backwards.
•Several hunting methods involve using air bubbles to herd, corral, or disorient fish. One highly complex variant, called "bubble netting" is unique to humpbacks. This technique is often performed in groups with defined roles for distracting, scaring, and herding before whales lunge at prey corralled near the surface.
•Their body coloration is primarily dark grey, but individuals have a variable amount of white on their pectoral fins and belly. This variation is so distinctive that the pigmentation pattern on the undersides of their "flukes" is used to identify individual whales, similar to a human fingerprint.
•Humpback whales are the favorite of whale watchers, as they frequently perform aerial displays, such as breaching (jumping out of the water), or slapping the surface with their pectoral fins, tails, or heads.
•Humpback whales travel great distances during their seasonal migration, the farthest migration of any mammal. The longest recorded migration was 5,160 miles (8,300 km); seven animals, including a calf, completed this trek from Costa Rica to Antarctica.
•Also on wintering grounds, males sing complex songs that can last up to 20 minutes and be heard 20 miles (30 km) away. A male may sing for hours, repeating the song several times. All males in a population sing the same song, but that song continually evolves over time. Humpback whale singing has been studied for decades, but scientists still understand very little about its function.

Not an albinistic alligator (has no Melatonin for color and lots of physical problems) but a leucistic alligator (reduced pigmentation via a recessive gene but otherwise normal). White tigers fall into this category as well. Click on the links for better definitions of these conditions.
According the Gatorland signs, the four white gators they have are handfuls. This one is Bouya Blan (Creole for "White Fog") but the most dangerous one is his brother, Feros Zombi; they need to have two handlers in with him at all times to deflect his attacks. Whoa!
Polar Bear
"Region: America
Class: Mammalia
Order: Carnivora
Family: Ursidae
Genus: Ursus
Scientific Name: Ursus maritimus
Description : Polar bears are considered the largest land carnivores in the world, matched only by very large individual Kodiak brown bears. Both sexes differ in size throughout their range; males being much larger than females and continuing to grow for a longer period of time. These bears have long, massive skulls, necks and bodies with long legs and large paws. Ears and tail are short. The nose is more prominent or “Roman” with a black rhinarium (nose pad). The tongue is black and the eyes brown. The surface of the skin is also black. Fur colour varies slightly with the season: new coats grown just prior to the winter season are very white appearing as slightly creamy white against the stark white of their icy winter environment. This pelage is thick, coarse and long with dense underfur. Guard hairs, found throughout the pelage, are shiny, almost glossy, oily and waterproof and have hollow shafts. Polar bears moult annually between the end of May and August. The coat becomes thinner and has a yellow wash or is almost a golden colour. Male polar bears weigh between 400 – 600 kg, and have been recorded up to a maximum of 800 kg. Females are smaller than the males weighing up to 300 kg, and when pregnant up to 460 kg. Polar bears are 2.5 – 3.5 m long.
Distribution : The polar bear is circumpolar in distribution, inhabiting all Arctic seas and coastlines. It is found on the pack-ice off the Alaskan coast north of Bering Strait, off the coasts of Greenland and along the Eurasian Arctic coast from Spitsbergen to Wrangell Island. Rare stragglers reach Iceland. Individual bears have been seen on the frozen Arctic Ocean as far as latitude 88 degrees North, only 2 degrees from the North Pole. In Canada, they are found along the Arctic coasts from Alaska to Labrador and from the tip of James Bay to northern Ellesmere Island. Polar bears do roam as far as 150 kilometres inland into the coniferous forests, where they live very differently from the polar bears which belong to the high Arctic.
Habitat : They prefer areas of annual ice, which they use as a hunting platform and protective cover. This includes snow-drifted pressure ridges, refrozen cracks and areas of open water surrounded by ice. In areas where the pack ice melts by mid to late summer they come inland and live in coniferous forest areas. Here they remain until the ice re-freezes. Areas of solidly frozen sea ice and the open seas are avoided. Generally they are most common along coastal areas. Some do enter the permanent pack ice.
Food : The ringed seal is by far the most common prey. They also eat bearded seal, harp seal and hooded seal. Young walrus are sometimes taken. During the summer months they feed upon the shoreline carrion, fish, mussels, crabs, starfish, lemmings and the eggs and nestling young of waterfowl and cliff-dwelling birds. They will also graze on kelp, grasses and eat mushrooms and crowberries.
Reproduction and Development : Normally they are solitary animals outside the breeding season, the exception being a mother with cubs. Polar bears mate in mid-summer. Females first start to breed at 3 to 5 years of age. In April and May adult females are in oestrus and ready to accept a mate. They are polyandrous, meaning one female will mate with more than one male in one breeding season. Males fight among themselves for the female’s attention and a couple will pair off for a period of a few days to two weeks. With females, delayed implantation occurs, the fertilized egg does not implant in the uterus until mid-September to mid-October. Embryonic development begins at this time. Gestation periods, therefore, vary a great deal when including this period of delay. Females choose suitable locations to build their maternity dens in mid-October and retreat to them for the winter season. They give birth to one to four cubs somewhere between late November and early January. Twins are most common. The newborns are small; 25 to 30 cm long and weigh less than 1 kg. They are covered with very fine hair, appearing almost naked and their eyes are closed. Their eyes open at 6 weeks. Growth is very quick; at two months their fur has thickened; they weigh about 5 kg and move about the den. By mid-March to early April, when the den is opened, the cubs weigh about 10 kg and are surprisingly strong. The cubs suckle for nine months, occasionally one year. They are very dependent on their mother and stay with her for two years. At that time they weigh 90 - 180 kg and are half grown.
Adaptations : Polar bears are wonderfully adapted to their Arctic surroundings.
Locomotion. On land a shuffling walk may be increased to a rolling gallop of 40 km/h and can outrun caribou over a short distance. Bears are often seen standing high on their hind legs, necks stretched to scan the landscape. On thin ice, legs are spread to distribute body mass. Thickly padded and furred soles allow the bear to move quietly as well as providing good traction. Small bumps and cavities on the soles act like suction cups keeping bears from slipping on the ice. The claws are used to dig into icy slopes and to grip prey. They are strong swimmers, paddling with their forefeet only and trailing their hind feet which act as a rudder. They can stay submerged for over one minute, keeping their eyes open. They swim at a speed of approximately 6.4 km/h, often covering long distances.
Insulation. Polar bears have a thick layer of sub-cutaneous fat and very dense underfur with several layers of glossy guard hair on the outside. Their pelt is much thicker in winter and provides excellent insulation. The fat layer also adds to buoyancy in the water. Water is shed easily from the oily waterproof fur. Small, furry ears have a heavy network of blood vessels, keeping them warm and conserving heat. The tail is short and rounded also conserving heat. Fur is very dense around the soles of the feet.
Pelage. The creamy white appearance of the coat allows the bear to be inconspicuous when hunting seal. Each hair is similar to an optical fibre; colourless and hollow. Being translucent, it reflects the heat from the sun down to the base of the hair, where it is absorbed by the black skin. Whiteness comes from reflection of light rather than pigmentation.
Hunting. Bears use their keen sense of smell to detect seal breathing holes. These can be up to a kilometer away and covered by a layer of snow and ice. They will stand or lie by the seal’s blowhole in the ice for hours; they may swim towards seals resting on the ice flows with only their nose showing above the water. They will dive quietly, then swim up to the ice edge and jump out on the seal, and will also crawl towards a sunbathing seal using every piece of raised ice to conceal the approach.
Denning. Both sexes occupy dens for shelter. Topographic factors influence the den sites. In Canadian core areas, dens frequently occur on south-facing slopes where northerly prevailing winds create the best drifts, where the wind-chill is least and insulation from received solar radiation is greatest. One of the three largest denning areas worldwide is in Canada. There are three main types of winter refuges: maternity dens, temporary dens and winter shelters. During the winter any bear may dig a temporary den and use it for a few days during a storm, or take shelter in a natural cavity. Winter shelters are used for longer periods of time as resting places. This type of shelter is usually roomier with additional features such as alcoves, porches and ventilation holes. Bears do not hibernate in the strict sense of the word; they have the ability to slow down their metabolism to conserve energy at any time of year. The state of self-induced lethargy while in the shelter allows them to preserve their vital fat reserves. During this time, the body temperature of the polar bear decreases by a few degrees from normal and the respiration rates are markedly reduced. Maternity dens are built and occupied by pregnant females and can vary in size. The denning chamber is at the upper end of an entrance tunnel 1 to 2 m long. It averages 1.5 m in diameter with a height of 90 to 100cm in the middle. Drifting snow seals the entrance. The chamber is higher than the tunnel, trapping bear body heat inside. Dens not only provide a safe place to give birth to her cubs, but are also a place of protection for the cubs during their first few months. During this time she does not leave the den, remaining with her cubs and living on her reserves of fat. In the spring, with her fat severely depleted she must leave to find food to sustain herself and her cubs. After they leave the maternity den she will build temporary refuges in which to nurse, rest and shelter her young cubs and warms them as they all sleep together. She heads with her cubs towards the nearest supply of food, this is usually pack ice.
Sight and sounds. Polar bears have good eyesight. Their eyes have inner eyelids that keep the glare of the sun on snow and ice from blinding them. When defending a food source from other bears they use a deep growl. They hiss and snort to show aggression. Angry bears use loud roars and growls. Mothers scold cubs with a low growl.
Threats to Survival : Polar bears are one of the animals most threatened by global warming. They depend entirely on sea ice as a platform from which to hunt seals. Reduction of the total ice cover in the Arctic is a serious concern globally. When the ice does not form or forms too late in the season many polar bears starve. In Hudson Bay, scientists have found the main cause of death for cubs to be either lack of food or lack of fat on nursing mothers. Exploitation of minerals and fossil fuels in the Arctic pose a continuous threat. Of the oil and natural gas deposits globally, 20% are located in the Arctic. As the ice cap recedes these become more accessible. Countries are competing which each other in claiming ownership of Arctic and its resources. This can only result in further and more drastic impact on polar bear habitat.

While in DC for our Centennial Celebration. The nephew and I took a trip to Howard University where it all started for Delta Sigma Theta Sorority, Inc. Pictured here is me standing in front of "Lady Fortitude"
"Lady Fortitude"
On April 28, 1979, members of Alpha Chapter, Delta Sigma Theta Sorority, Incorporated, a national public service sorority founded at Howard University in 1913, unveiled a sculpture in the Valley Mall at 3:15 p.m. to honor its founders.
Called "Fortitude," the steel-fabricated sculpture, created by James King, stands 12 feet and 6 inches in height and has an amazing 12 feet arm to arm span. The sculpture symbolizes the attributes of strength, courage, hope, wisdom, beauty and femininity as depicted by the 22 founders of Delta Sigma Theta Sorority, Incorporated.
The art expression is sculpted in corten steel. The metal grows in beauty with age and through the process of oxidization, the color changes from silver to a rustic red-orange to a dark rich bronze tone. The total process can take about two to three years.
The figure is shown pushing forward as the tension of her thighs portrays strength. Her outreached hand denotes receiving of love and the giving of oneself to others. Her facial features depict courage and determination. Her color tone represents the glorious gradations of pigmentations of the Black woman. The total form not only denotes fortitude but stands to inspire women, in particular Black women, to move forcefully to meet the challenges of life.
The sculptor James King is one of the nation's most gifted sculptors. He was born in Chicago and was educated at a number of elite universities around the world, including The Art Institute of Chicago, Goethe Institute and The University of Vienna.

Cultura Yombe (R.d.C.) maschera femminile ngobudi,- nganga diphomba
l Kongo (o Bakongo) storicamente abitano la costa occidentale dell'Africa centrale, ora confinata nella parte meridionale della Repubblica Democratica del Congo e nel nord dell'Angola. I Kongo mantengono una cultura religiosa animista basata sui culti degli antenati e sull'adorazione del dio supremo Nzambi. Il popolo Kongo è diviso in diverse sotto etnie, tra cui Beembe, Bwende, Vili, Sundi e i creatori di questa maschera, gli Yombe. Mentre in tutto il territorio In tutto il territorio del Kongo, il Nganga (veggente) possedeva una o più figure di potere o nkisi, solo nelle regioni occidentali abitate dagli Yombe questa figura rituale possedeva anche una o più maschere. Il loro ruolo era quello di mediare il controllo dei poteri relativi all'opera di nkisi. L'uso di queste maschere era limitato a una certa area culturale, il che spiega la loro estrema rarità. Conosciute come ngobudi, le maschere Yombe possono essere considerate come ritratti idealizzati del veggente, o anche come una letterale "interfaccia" che separa il veggente dai suoi stessi poteri magici. L'aspetto della più belle tra queste maschere è caratterizzato da un fortissimo naturalismo, caratterizzate per la loro pigmentazione bicolore, e per la serenità che emana dall'espressione
Il nganga diphomba, svolge un ruolo importante nella società Yombe, rilevando e punendo la stregoneria. La maggior parte dei principali mali sociali sono attribuiti alla stregoneria nelle culture Kongo, inclusi siccità, criminalità e incidenti. La società degli indovini indossa due tipi di maschere per identificare e punire gli stregoni, maschi (con la barba) e femmine (con il ciuffo). Entrambe le maschere evocano gli spiriti degli antenati al fine di proteggere il veggente. Con la maschera si dipingono il corpo e indossano una gonna di piume di turaco e una cintura di sonagli di ottone. Usano la loro stregoneria (kundu) per individuare il colpevole e contrastare le loro maledizioni.
Tali maschere possono essere utilizzate anche dalla Khimba Society nei rituali di iniziazione degli adulti, probabilmente dallo stesso nganga diphomba.
TThroughout the Kongo territory, the nganga (seer) possessed one or several power figures or nkisi. It is only in the western regions inhabited by the Yombe that the nganga also possessed one or several masks. Their role was to mediate the control of powers relating to the work of nkisi.The use of these masks was limited to a certain cultural area, which explains their extreme rarity. Known as ngobudi, Yombe masks may be considered as idealized portraits of the seer, or even as a literal ‘interface’ separating the seer from his own magical powers. The appearance of the best of these masks is characterized by a very strong naturalism. These masks are more remarkable for their bicolor - often black-and-white - pigmentation, and the serenity that emanates from the expression.
The Kongo (or Bakongo) is a populous nation historically inhabiting the west coast of central Africa, now confined to the southern part of the Democratic Republic of Congo and northern Angola. The Kongo maintain an animistic religion based on ancestor cults and worship of the supreme god Nzambi. The Kongo people are divided into several subethnicities, including Beembe, Bwende, Vili, Sundi, and the makers of this mask, the Yombe.The nganga diphomba, or diviner, plays an important role in Yombe society, detecting and punishing sorcery. Most major social ills are attributed to sorcery in Kongo cultures, including drought, crime, and accidents. The society of diviners wears two kinds of masks to identify and punish sorcerers, male (with a beard) and female (with a topknot). Both masks evoke ancestor spirits for the protection fo the diviner. With the mask, they paint their bodies and wear a skirt of turaco feathers and a belt of brass bells. They use their own sorcery (kundu) to detect the culprit and counteract their curses.Such masks may also be also used by the Khimba Society in adult initiation rituals, probably by the nganga diphomba himself.

Albino Alligator at the Cape May County Park & Zoo
Albinism (from Latin albus, "white"; see extended etymology, also called achromia, achromasia, or achromatosis) is a congenital disorder characterized by the complete or partial absence of pigment in the skin, hair and eyes due to absence or defect of an enzyme involved in the production of melanin. Albinism results from inheritance of recessive gene alleles and is known to affect all vertebrates, including humans. While an organism with complete absence of melanin is called an albino ,an organism with only a diminished amount of melanin is described as albinoid.
Albinism is associated with a number of vision defects, such as photophobia, nystagmus and astigmatism. Lack of skin pigmentation makes the organism more susceptible to sunburn and skin cancers.
Ellie was the first woman to contact me about being part of my 2% project. From the very first email and becoming acquainted with her over several weeks prior to and during the shoot, it was evident that she was very genuine and has a lot of positive personality traits that are, unfortunately, becoming rare in today’s society.
Another rarity is her colouring. Red hair and blue eyes are the rarest colour combination on the planet. 2% of the global population has red hair, but only .17% have red hair and blue eyes. To top all that, she also has another feature in her eyes called Central Heterochromia (more than one eye colour). This genetic variance affects the pigmentation of the eyes and in Ellie’s case, created a golden ring in her iris around the pupils while the rest of the iris is blue. This creates a beautiful brilliance in Ellie’s eyes that really stand out! Heterochromia affects only 1% of the global population. Go full screen for a better view.

The pomegranate (/ˈpɒmᵻɡrænᵻt/), botanical name Punica granatum, is a fruit-bearing deciduous shrub or small tree growing between 5 and 8 m tall.
In the Northern Hemisphere, the fruit is typically in season from September to February, and in the Southern Hemisphere from March to May. As intact arils or juice, pomegranates are used in cooking, baking, meal garnishes, juice blends, smoothies, and alcoholic beverages, such as cocktails and wine.
The pomegranate originated in the region of modern-day Iran and has been cultivated since ancient times throughout the Mediterranean region and northern India. It was introduced into America (Spanish America) in the late 16th century and California by Spanish settlers in 1769.
Today, it is widely cultivated throughout the Middle East and Caucasus region, north Africa and tropical Africa, the Indian subcontinent, Central Asia, the drier parts of southeast Asia, and parts of the Mediterranean Basin. It is also cultivated in parts of California and Arizona. In recent years, it has become more common in the commercial markets of Europe and the Western Hemisphere.
ETYMOLOGY
The name pomegranate derives from medieval Latin pōmum "apple" and grānātum "seeded". Perhaps stemming from the old French word for the fruit, pomme-grenade, the pomegranate was known in early English as "apple of Grenada" - a term which today survives only in heraldic blazons. This is a folk etymology, confusing Latin granatus with the name of the Spanish city of Granada, which derives from Arabic.
Garnet derives from Old French grenat by metathesis, from Medieval Latin granatum as used in a different meaning "of a dark red color". This derivation may have originated from pomum granatum describing the color of pomegranate pulp or from granum referring to "red dye, cochineal".
The French term for pomegranate, grenade, has given its name to the military grenade.
DESCRIPTION
A shrub or small tree growing 6 to 10 m high, the pomegranate has multiple spiny branches, and is extremely long-lived, with some specimens in France surviving for 200 years. P. granatum leaves are opposite or subopposite, glossy, narrow oblong, entire, 3–7 cm long and 2 cm broad. The flowers are bright red and 3 cm in diameter, with three to seven petals. Some fruitless varieties are grown for the flowers alone.
The edible fruit is a berry, intermediate in size between a lemon and a grapefruit, 5–12 cm in diameter with a rounded shape and thick, reddish skin. The number of seeds in a pomegranate can vary from 200 to about 1400. Each seed has a surrounding water-laden pulp — the edible sarcotesta that forms from the seed coat — ranging in color from white to deep red or purple. The seeds are "exarillate", i.e., unlike some other species in the order, Myrtales, no aril is present. The sarcotesta of pomegranate seeds consists of epidermis cells derived from the integument. The seeds are embedded in a white, spongy, astringent membrane.
CULTIVATION
P. granatum is grown for its fruit crop, and as ornamental trees and shrubs in parks and gardens. Mature specimens can develop sculptural twisted-bark multiple trunks and a distinctive overall form. Pomegranates are drought-tolerant, and can be grown in dry areas with either a Mediterranean winter rainfall climate or in summer rainfall climates. In wetter areas, they can be prone to root decay from fungal diseases. They can be tolerant of moderate frost, down to about −12 °C.
Insect pests of the pomegranate can include the pomegranate butterfly Virachola isocrates and the leaf-footed bug Leptoglossus zonatus, and fruit flies and ants are attracted to unharvested ripe fruit. Pomegranate grows easily from seed, but is commonly propagated from 25– to 50-cm hardwood cuttings to avoid the genetic variation of seedlings. Air layering is also an option for propagation, but grafting fails.
VARIETIES
P. granatum var. nana is a dwarf variety of P. granatum popularly planted as an ornamental plant in gardens and larger containers, and used as a bonsai specimen tree. It could well be a wild form with a distinct origin. It has gained the Royal Horticultural Society's Award of Garden Merit. The only other species in the genus Punica is the Socotran pomegranate (P. protopunica), which is endemic to the island of Socotra. It differs in having pink (not red) flowers and smaller, less sweet fruit.
CULTIVARS
P. granatum has more than 500 named cultivars, but evidently has considerable synonymy in which the same genotype is named differently across regions of the world.[15]
Several characteristics between pomegranate genotypes vary for identification, consumer preference, preferred use, and marketing, the most important of which are fruit size, exocarp color (ranging from yellow to purple, with pink and red most common), seed-coat color (ranging from white to red), hardness of seed, maturity, juice content and its acidity, sweetness, and astringency.
CULTURAL HISTORY
Pomegranate is native to a region from Iran to northern India. Pomegranates have been cultivated throughout the Middle East, South Asia, and Mediterranean region for several millennia, and also thrive in the drier climates of California and Arizona.
Carbonized exocarp of the fruit has been identified in early Bronze Age levels of Jericho in the West Bank, as well as late Bronze Age levels of Hala Sultan Tekke on Cyprus and Tiryns.[citation needed] A large, dry pomegranate was found in the tomb of Djehuty, the butler of Queen Hatshepsut in Egypt; Mesopotamian cuneiform records mention pomegranates from the mid-third millennium BC onwards.
It is also extensively grown in South China and in Southeast Asia, whether originally spread along the route of the Silk Road or brought by sea traders. Kandahar is famous in Afghanistan for its high-quality pomegranates.
Although not native to Korea or Japan, the pomegranate is widely grown there and many cultivars have been developed. It is widely used for bonsai because of its flowers and for the unusual twisted bark the older specimens can attain. The term "balaustine" (Latin: balaustinus) is also used for a pomegranate-red color.
The ancient city of Granada in Spain was renamed after the fruit during the Moorish period and today the province of Granada uses pomegranate as a charge in heraldry for its canting arms.
Spanish colonists later introduced the fruit to the Caribbean and America (Spanish America), but in the English colonies, it was less at home: "Don't use the pomegranate inhospitably, a stranger that has come so far to pay his respects to thee," the English Quaker Peter Collinson wrote to the botanizing John Bartram in Philadelphia, 1762. "Plant it against the side of thy house, nail it close to the wall. In this manner it thrives wonderfully with us, and flowers beautifully, and bears fruit this hot year. I have twenty-four on one tree... Doctor Fothergill says, of all trees this is most salutiferous to mankind."
The pomegranate had been introduced as an exotic to England the previous century, by John Tradescant the elder, but the disappointment that it did not set fruit there led to its repeated introduction to the American colonies, even New England. It succeeded in the South: Bartram received a barrel of pomegranates and oranges from a correspondent in Charleston, South Carolina, 1764. John Bartram partook of "delitious" pomegranates with Noble Jones at Wormsloe Plantation, near Savannah, Georgia, in September 1765. Thomas Jefferson planted pomegranates at Monticello in 1771: he had them from George Wythe of Williamsburg.
CULINARY USE
After the pomegranate is opened by scoring it with a knife and breaking it open, the seeds are separated from the peel and internal white pulp membranes. Separating the seeds is easier in a bowl of water because the seeds sink and the inedible pulp floats. Freezing the entire fruit also makes it easier to separate. Another effective way of quickly harvesting the seeds is to cut the pomegranate in half, score each half of the exterior rind four to six times, hold the pomegranate half over a bowl, and smack the rind with a large spoon. The seeds should eject from the pomegranate directly into the bowl, leaving only a dozen or more deeply embedded seeds to remove. The entire seed is consumed raw, though the watery, tasty sarcotesta is the desired part. The taste differs depending on the variety or cultivar of pomegranate and its ripeness.
Pomegranate juice can be sweet or sour, but most fruits are moderate in taste, with sour notes from the acidic tannins contained in the juice. Pomegranate juice has long been a popular drink in Europe, the Middle East and is now widely distributed in the United States and Canada.
Grenadine syrup long ago consisted of thickened and sweetened pomegranate juice, now is usually a sales name for a syrup based on various berries, citric acid, and food coloring, mainly used in cocktail mixing. In Europe, Bols still manufactures grenadine syrup with pomegranate. Before tomatoes, a New World fruit, arrived in the Middle East, pomegranate juice, molasses, and vinegar were widely used in many Iranian foods, and are still found in traditional recipes such as fesenjān, a thick sauce made from pomegranate juice and ground walnuts, usually spooned over duck or other poultry and rice, and in ash-e anar (pomegranate soup).
Pomegranate seeds are used as a spice known as anardana (from Persian: anar + dana, pomegranate + seed), most notably in Indian and Pakistani cuisine. Dried whole seeds can often be obtained in ethnic Indian subcontinent markets. These seeds are separated from the flesh, dried for 10–15 days, and used as an acidic agent for chutney and curry preparation. Ground anardana is also used, which results in a deeper flavoring in dishes and prevents the seeds from getting stuck in teeth. Seeds of the wild pomegranate variety known as daru from the Himalayas are regarded as quality sources for this spice.
Dried pomegranate seeds, found in some natural specialty food markets, still contain some residual water, maintaining a natural sweet and tart flavor. Dried seeds can be used in several culinary applications, such as trail mix, granola bars, or as a topping for salad, yogurt, or ice cream.
In the Caucasus, pomegranate is used mainly for juice. In Azerbaijan, a sauce from pomegranate juice narsharab, (from Persian: (a)nar + sharab, lit. "pomegranate wine") is usually served with fish or tika kabab. In Turkey, pomegranate sauce (Turkish: nar ekşisi) is used as a salad dressing, to marinate meat, or simply to drink straight. Pomegranate seeds are also used in salads and sometimes as garnish for desserts such as güllaç. Pomegranate syrup or molasses is used in muhammara, a roasted red pepper, walnut, and garlic spread popular in Syria and Turkey.
In Greece, pomegranate (Greek: ρόδι, rodi) is used in many recipes, including kollivozoumi, a creamy broth made from boiled wheat, pomegranates, and raisins, legume salad with wheat and pomegranate, traditional Middle Eastern lamb kebabs with pomegranate glaze, pomegranate eggplant relish, and avocado-pomegranate dip. Pomegranate is also made into a liqueur, and as a popular fruit confectionery used as ice cream topping, mixed with yogurt, or spread as jam on toast. In Cyprus and Greece, and among the Greek Orthodox Diaspora, ρόδι (Greek for pomegranate) is used to make koliva, a mixture of wheat, pomegranate seeds, sugar, almonds, and other seeds served at memorial services.
In Mexico, they are commonly used to adorn the traditional dish chiles en nogada, representing the red of the Mexican flag in the dish which evokes the green (poblano pepper), white (nogada sauce) and red (pomegranate seeds) tricolor.
IN TRADITIONAL MEDICINE
In the Indian subcontinent's ancient Ayurveda system of traditional medicine, the pomegranate is frequently described as an ingredient in remedies.
In folk medicine pomegranate has been thought a contraceptive and abortifacient when the seeds or rind are eaten, or when as a vaginal suppository.
NUTRITION
A 100-g serving of pomegranate seeds provides 12% of the Daily Value (DV) for vitamin C, 16% DV for vitamin K and 10% DV for folate (table).
Pomegranate seeds are an excellent source of dietary fiber (20% DV) which is entirely contained in the edible seeds. People who choose to discard the seeds forfeit nutritional benefits conveyed by the seed fiber and micronutrients.
Pomegranate seed oil contains punicic acid (65.3%), palmitic acid (4.8%), stearic acid (2.3%), oleic acid (6.3%), and linoleic acid (6.6%).
RESEARCH
JUICE
The most abundant phytochemicals in pomegranate juice are polyphenols, including the hydrolyzable tannins called ellagitannins formed when ellagic acid and/or gallic acid binds with a carbohydrate to form pomegranate ellagitannins, also known as punicalagins.
The red color of juice can be attributed to anthocyanins, such as delphinidin, cyanidin, and pelargonidin glycosides. Generally, an increase in juice pigmentation occurs during fruit ripening.
The phenolic content of pomegranate juice is adversely affected by processing and pasteurization techniques.
PEEL
Compared to the pulp, the inedible pomegranate peel contains as much as three times the total amount of polyphenols, including condensed tannins, catechins, gallocatechins and prodelphinidins.
The higher phenolic content of the peel yields extracts for use in dietary supplements and food preservatives.
Health claims
Despite limited research data, manufacturers and marketers of pomegranate juice have liberally used evolving research results for product promotion. In February 2010, the FDA issued a Warning Letter to one such manufacturer, POM Wonderful, for using published literature to make illegal claims of unproven anti-disease benefits.
SYMBOLISM
ANCIENT EGYPT
Ancient Egyptians regarded the pomegranate as a symbol of prosperity and ambition. According to the Ebers Papyrus, one of the oldest medical writings from around 1500 BC, Egyptians used the pomegranate for treatment of tapeworm and other infections.
ANCIENT GREECE
The Greeks were familiar with the fruit far before it was introduced to Rome via Carthage. In Ancient Greek mythology, the pomegranate was known as the "fruit of the dead", and believed to have sprung from the blood of Adonis.
The myth of Persephone, the goddess of the underworld, prominently features the pomegranate. In one version of Greek mythology, Persephone was kidnapped by Hades and taken off to live in the underworld as his wife. Her mother, Demeter (goddess of the Harvest), went into mourning for her lost daughter, thus all green things ceased to grow. Zeus, the highest-ranking of the Greek gods, could not allow the Earth to die, so he commanded Hades to return Persephone. It was the rule of the Fates that anyone who consumed food or drink in the underworld was doomed to spend eternity there. Persephone had no food, but Hades tricked her into eating six pomegranate seeds while she was still his prisoner, so she was condemned to spend six months in the underworld every year. During these six months, while Persephone sits on the throne of the underworld beside her husband Hades, her mother Demeter mourns and no longer gives fertility to the earth. This was an ancient Greek explanation for the seasons. Dante Gabriel Rossetti's painting Persephona depicts Persephone holding the fatal fruit. The number of seeds Persephone ate varies, depending on which version of the story is told. The number ranges from three to seven, which accounts for just one barren season if it is just three or four seeds, or two barren seasons (half the year) if she ate six or seven seeds.
The pomegranate also evoked the presence of the Aegean Triple Goddess who evolved into the Olympian Hera, who is sometimes represented offering the pomegranate, as in the Polykleitos' cult image of the Argive Heraion (see below). According to Carl A. P. Ruck and Danny Staples, the chambered pomegranate is also a surrogate for the poppy's narcotic capsule, with its comparable shape and chambered interior. On a Mycenaean seal illustrated in Joseph Campbell's Occidental Mythology 1964, figure 19, the seated Goddess of the double-headed axe (the labrys) offers three poppy pods in her right hand and supports her breast with her left. She embodies both aspects of the dual goddess, life-giving and death-dealing at once. The Titan Orion was represented as "marrying" Side, a name that in Boeotia means "pomegranate", thus consecrating the primal hunter to the Goddess. Other Greek dialects call the pomegranate rhoa; its possible connection with the name of the earth goddess Rhea, inexplicable in Greek, proved suggestive for the mythographer Karl Kerenyi, who suggested the consonance might ultimately derive from a deeper, pre-Indo-European language layer.
In the 5th century BC, Polycleitus took ivory and gold to sculpt the seated Argive Hera in her temple. She held a scepter in one hand and offered a pomegranate, like a 'royal orb', in the other. "About the pomegranate I must say nothing," whispered the traveller Pausanias in the 2nd century, "for its story is somewhat of a holy mystery." In the Orion story, Hera cast pomegranate-Side (an ancient city in Antalya) into dim Erebus — "for daring to rival Hera's beauty", which forms the probable point of connection with the older Osiris/Isis story.[citation needed] Since the ancient Egyptians identified the Orion constellation in the sky as Sah the "soul of Osiris", the identification of this section of the myth seems relatively complete. Hera wears, not a wreath nor a tiara nor a diadem, but clearly the calyx of the pomegranate that has become her serrated crown.[citation needed] The pomegranate has a calyx shaped like a crown. In Jewish tradition, it has been seen as the original "design" for the proper crown. In some artistic depictions, the pomegranate is found in the hand of Mary, mother of Jesus.
A pomegranate is displayed on coins from the ancient city of Side, Pamphylia.
Within the Heraion at the mouth of the Sele, near Paestum, Magna Graecia, is a chapel devoted to the Madonna del Granato, "Our Lady of the Pomegranate", "who by virtue of her epithet and the attribute of a pomegranate must be the Christian successor of the ancient Greek goddess Hera", observes the excavator of the Heraion of Samos, Helmut Kyrieleis.
In modern times, the pomegranate still holds strong symbolic meanings for the Greeks. On important days in the Greek Orthodox calendar, such as the Presentation of the Virgin Mary and on Christmas Day, it is traditional to have at the dinner table polysporia, also known by their ancient name panspermia, in some regions of Greece. In ancient times, they were offered to Demeter[citation needed] and to the other gods for fertile land, for the spirits of the dead and in honor of compassionate Dionysus.[citation needed] When one buys a new home, it is conventional for a house guest to bring as a first gift a pomegranate, which is placed under/near the ikonostasi (home altar) of the house, as a symbol of abundance, fertility, and good luck. Pomegranates are also prominent at Greek weddings and funerals.[citation needed] When Greeks commemorate their dead, they make kollyva as offerings, which consist of boiled wheat, mixed with sugar and decorated with pomegranate. It is also traditional in Greece to break a pomegranate on the ground at weddings and on New Years. Pomegranate decorations for the home are very common in Greece and sold in most home goods stores.
ANCIENT ISRAEL AND JUDAISM
Pomegranates were known in Ancient Israel as the fruits which the scouts brought to Moses to demonstrate the fertility of the "promised land". The Book of Exodus describes the me'il ("robe of the ephod") worn by the Hebrew high priest as having pomegranates embroidered on the hem alternating with golden bells which could be heard as the high priest entered and left the Holy of Holies. According to the Books of Kings, the capitals of the two pillars (Jachin and Boaz) that stood in front of Solomon's Temple in Jerusalem were engraved with pomegranates. Solomon is said to have designed his coronet based on the pomegranate's "crown" (calyx).
It is traditional to consume pomegranates on Rosh Hashana because, with its numerous seeds, it symbolizes fruitfulness. Also, it is said to have 613 seeds, which corresponds with the 613 mitzvot or commandments of the Torah.[61] This particular tradition is referred to in the opening pages of Ursula Dubosarsky's novel Theodora's Gift.
The pomegranate appeared on the ancient coins of Judea. When not in use, the handles of Torah scrolls are sometimes covered with decorative silver globes similar in shape to "pomegranates" (rimmonim). Some Jewish scholars believe the pomegranate was the forbidden fruit in the Garden of Eden.[60] Pomegranates are one of the Seven Species (Hebrew: שבעת המינים, Shiv'at Ha-Minim) of fruits and grains enumerated in the Hebrew Bible (Deuteronomy 8:8) as being special products of the Land of Israel. The pomegranate is mentioned in the Bible many times, including this quote from the Songs of Solomon, "Thy lips are like a thread of scarlet, and thy speech is comely: thy temples are like a piece of a pomegranate within thy locks." (Song of Solomon 4:3). Pomegranates also symbolize the mystical experience in the Jewish mystical tradition, or kabbalah, with the typical reference being to entering the "garden of pomegranates" or pardes rimonim; this is also the title of a book by the 16th-century mystic Moses ben Jacob Cordovero.

In the earliest incontrovertible appearance of Christ in a mosaic, a 4th-century floor mosaic from Hinton St Mary, Dorset, now in the British Museum, the bust of Christ and the chi rho are flanked by pomegranates. Pomegranates continue to be a motif often found in Christian religious decoration. They are often woven into the fabric of vestments and liturgical hangings or wrought in metalwork. Pomegranates figure in many religious paintings by the likes of Sandro Botticelli and Leonardo da Vinci, often in the hands of the Virgin Mary or the infant Jesus. The fruit, broken or bursting open, is a symbol of the fullness of Jesus' suffering and resurrection.
In the Eastern Orthodox Church, pomegranate seeds may be used in kolyva, a dish prepared for memorial services, as a symbol of the sweetness of the heavenly kingdom.
IN THE QUR´AN
According to the Qur'an, pomegranates grow in the gardens of paradise (55:68). The Qur'an also mentions pomegranates three times.(6:99, 6:141, 55:68)
AFGHANISTAN
Pomegranate, a favorite fall and winter fruit in Afghanistan, has mainly two varieties: one that is sweet and dark red with hard seeds growing in and around Kandhar province, and the other that has soft seeds with variable color growing in the central/northern region. The largest market for Afghan pomegranates is India followed by Pakistan, Russia, United Arab Emirates and Europe.
ARMENIA
The pomegranate is one of the main fruits in Armenian culture (the others being apricot and grapes). Its juice is famous with Armenians in food and heritage. The pomegranate is the symbol of Armenia and represents fertility, abundance and marriage. For example, the fruit played an integral role in a wedding custom widely practiced in ancient Armenia: a bride was given a pomegranate fruit, which she threw against a wall, breaking it into pieces. Scattered pomegranate seeds ensured the bride future children. In Karabakh, it was customary to put fruits next to the bridal couple during the first night of marriage, among them the pomegranate, which was said to ensure happiness. It is likely that newlyweds also enjoyed pomegranate wine. The symbolism of the pomegranate is that it protected a woman from infertility and protected a man's virility. Both homemade and commercial wine is made from pomegranate in Armenia. The Color of Pomegranates (1969) is a movie directed by Sergei Parajanov. It is a biography of the Armenian ashug Sayat-Nova (King of Song) which attempts to reveal the poet's life visually and poetically rather than literally.
AZERBAIJAN
Pomegranate is considered one of the symbols of Azerbaijan. Annually in October, a cultural festival is held in Goychay, Azerbaijan known as the Goychay Pomegranate Festival. The festival features Azerbaijani fruit-cuisine mainly the pomegranates from Goychay, which is famous for its pomegranate growing industry. At the festival, a parade is held with traditional Azerbaijani dances and Azerbaijani music. Pomegranate was depicted on the official logo of the 2015 European Games held in Azerbaijan. Nar the Pomegranate was one of the two mascots of these games. Pomegranates also featured on the jackets worn by Azerbaijani male athletes at the games' opening ceremony.
IRAN AND ANCIENT PERSIA
Pomegranate was the symbol of fertility in ancient Persian culture.[citation needed] In Persian mythology, Isfandiyar eats a pomegranate and becomes invincible. In the Greco-Persian Wars, Herodotus mentions golden pomegranates adorning the spears of warriors in the phalanx. Even in today's Iran, pomegranate may imply love and fertility.
Iran produces pomegranates as a common crop.[citation needed] Its juice and paste have a role in some Iranian cuisines, e.g. chicken, ghormas and refreshment bars. Pomegranate skins may be used to stain wool and silk in the carpet industry.
Pomegranate Festival is an annual cultural and artistic festival held during October in Tehran[citation needed] to exhibit and sell pomegranates, food products and handicrafts.
PAKISTAN
The pomegranate (known as "anār" in Urdu) is a popular fruit in Pakistan. It is grown in Pakistan and is also imported from Afghanistan.
INDIA
In some Hindu traditions, the pomegranate (Hindi: anār) symbolizes prosperity and fertility, and is associated with both Bhoomidevi (the earth goddess) and Lord Ganesha (the one fond of the many-seeded fruit). The Tamil name maadulampazham is a metaphor for a woman's mind. It is derived from, maadhu=woman, ullam=mind, which means as the seeds are hidden, it is not easy to decipher a woman's mind.
CHINA
Introduced to China during the Tang Dynasty (618-907 AD), the pomegranate (Chinese: 石榴; pinyin: shíliu) in olden times was considered an emblem of fertility and numerous progeny. This symbolism is a pun on the Chinese character 子 (zǐ) which, as well as meaning seed, also means "offspring" thus a fruit containing so many seeds is a sign of fecundity. Pictures of the ripe fruit with the seeds bursting forth were often hung in homes to bestow fertility and bless the dwelling with numerous offspring, an important facet of traditional Chinese culture.
WIKIPEDIA
The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. In many contexts, potato refers to the edible tuber, but it can also refer to the plant itself. Common or slang terms include tater, tattie and spud. Potatoes were introduced to Europe in the second half of the 16th century by the Spanish. Today they are a staple food in many parts of the world and an integral part of much of the world's food supply. As of 2014, potatoes were the world's fourth-largest food crop after maize (corn), wheat, and rice.
Wild potato species can be found throughout the Americas, from the United States to southern Chile. The potato was originally believed to have been domesticated independently in multiple locations, but later genetic testing of the wide variety of cultivars and wild species traced a single origin for potatoes. In the area of present-day southern Peru and extreme northwestern Bolivia, from a species in the Solanum brevicaule complex, potatoes were domesticated approximately 7,000–10,000 years ago. In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated.
Following millennia of selective breeding, there are now over 1,000 different types of potatoes. Over 99% of presently cultivated potatoes worldwide descended from varieties that originated in the lowlands of south-central Chile, which have displaced formerly popular varieties from the Andes.
The importance of the potato as a food source and culinary ingredient varies by region and is still changing. It remains an essential crop in Europe, especially eastern and central Europe, where per capita production is still the highest in the world, while the most rapid expansion in production over the past few decades has occurred in southern and eastern Asia, with China and India leading the world in overall production as of 2014.
Being a nightshade similar to tomatoes, the vegetative and fruiting parts of the potato contain the toxin solanine and are not fit for human consumption. Normal potato tubers that have been grown and stored properly produce glycoalkaloids in amounts small enough to be negligible to human health, but if green sections of the plant (namely sprouts and skins) are exposed to light, the tuber can accumulate a high enough concentration of glycoalkaloids to affect human health.
ETYMOLOGY
The English word potato comes from Spanish patata (the name used in Spain). The Spanish Royal Academy says the Spanish word is a hybrid of the Taíno batata (sweet potato) and the Quechua papa (potato). The name originally referred to the sweet potato although the two plants are not closely related. The 16th-century English herbalist John Gerard referred to sweet potatoes as "common potatoes", and used the terms "bastard potatoes" and "Virginia potatoes" for the species we now call "potato". In many of the chronicles detailing agriculture and plants, no distinction is made between the two. Potatoes are occasionally referred to as "Irish potatoes" or "white potatoes" in the United States, to distinguish them from sweet potatoes.
The name spud for a small potato comes from the digging of soil (or a hole) prior to the planting of potatoes. The word has an unknown origin and was originally (c. 1440) used as a term for a short knife or dagger, probably related to the Latin "spad-" a word root meaning "sword"; cf. Spanish "espada", English "spade" and "spadroon". It subsequently transferred over to a variety of digging tools. Around 1845, the name transferred to the tuber itself, the first record of this usage being in New Zealand English. The origin of the word "spud" has erroneously been attributed to an 18th-century activist group dedicated to keeping the potato out of Britain, calling itself The Society for the Prevention of Unwholesome Diet (S.P.U.D.). It was Mario Pei's 1949 The Story of Language that can be blamed for the word's false origin. Pei writes, "the potato, for its part, was in disrepute some centuries ago. Some Englishmen who did not fancy potatoes formed a Society for the Prevention of Unwholesome Diet. The initials of the main words in this title gave rise to spud." Like most other pre-20th century acronymic origins, this is false, and there is no evidence that a Society for the Prevention of Unwholesome Diet ever existed.
CHARACTERISTICS
Potato plants are herbaceous perennials that grow about 60 cm high, depending on variety, with the leaves dying back after flowering, fruiting and tuber formation. They bear white, pink, red, blue, or purple flowers with yellow stamens. In general, the tubers of varieties with white flowers have white skins, while those of varieties with colored flowers tend to have pinkish skins. Potatoes are mostly cross-pollinated by insects such as bumblebees, which carry pollen from other potato plants, though a substantial amount of self-fertilizing occurs as well. Tubers form in response to decreasing day length, although this tendency has been minimized in commercial varieties.
After flowering, potato plants produce small green fruits that resemble green cherry tomatoes, each containing about 300 seeds. Like all parts of the plant except the tubers, the fruit contain the toxic alkaloid solanine and are therefore unsuitable for consumption. All new potato varieties are grown from seeds, also called "true potato seed", "TPS" or "botanical seed" to distinguish it from seed tubers. New varieties grown from seed can be propagated vegetatively by planting tubers, pieces of tubers cut to include at least one or two eyes, or cuttings, a practice used in greenhouses for the production of healthy seed tubers. Plants propagated from tubers are clones of the parent, whereas those propagated from seed produce a range of different varieties.
GENETICS
There are about 5,000 potato varieties worldwide. Three thousand of them are found in the Andes alone, mainly in Peru, Bolivia, Ecuador, Chile, and Colombia. They belong to eight or nine species, depending on the taxonomic school. Apart from the 5,000 cultivated varieties, there are about 200 wild species and subspecies, many of which can be cross-bred with cultivated varieties. Cross-breeding has been done repeatedly to transfer resistances to certain pests and diseases from the gene pool of wild species to the gene pool of cultivated potato species. Genetically modified varieties have met public resistance in the United States and in the European UnionThe major species grown worldwide is Solanum tuberosum (a tetraploid with 48 chromosomes), and modern varieties of this species are the most widely cultivated. There are also four diploid species (with 24 chromosomes): S. stenotomum, S. phureja, S. goniocalyx, and S. ajanhuiri. There are two triploid species (with 36 chromosomes): S. chaucha and S. juzepczukii. There is one pentaploid cultivated species (with 60 chromosomes): S. curtilobum. There are two major subspecies of Solanum tuberosum: andigena, or Andean; and tuberosum, or Chilean. The Andean potato is adapted to the short-day conditions prevalent in the mountainous equatorial and tropical regions where it originated; the Chilean potato, however, native to the Chiloé Archipelago, is adapted to the long-day conditions prevalent in the higher latitude region of southern Chile.
The International Potato Center, based in Lima, Peru, holds an ISO-accredited collection of potato germplasm. The international Potato Genome Sequencing Consortium announced in 2009 that they had achieved a draft sequence of the potato genome. The potato genome contains 12 chromosomes and 860 million base pairs, making it a medium-sized plant genome. More than 99 percent of all current varieties of potatoes currently grown are direct descendants of a subspecies that once grew in the lowlands of south-central Chile. Nonetheless, genetic testing of the wide variety of cultivars and wild species affirms that all potato subspecies derive from a single origin in the area of present-day southern Peru and extreme Northwestern Bolivia (from a species in the Solanum brevicaule complex). The wild Crop Wild Relatives Prebreeding project encourages the use of wild relatives in breeding programs. Enriching and preserving the gene bank collection to make potatoes adaptive to diverse environmental conditions is seen as a pressing issue due to climate change.
Most modern potatoes grown in North America arrived through European settlement and not independently from the South American sources, although at least one wild potato species, Solanum fendleri, naturally ranges from Peru into Texas, where it is used in breeding for resistance to a nematode species that attacks cultivated potatoes. A secondary center of genetic variability of the potato is Mexico, where important wild species that have been used extensively in modern breeding are found, such as the hexaploid Solanum demissum, as a source of resistance to the devastating late blight disease. Another relative native to this region, Solanum bulbocastanum, has been used to genetically engineer the potato to resist potato blight.
Potatoes yield abundantly with little effort, and adapt readily to diverse climates as long as the climate is cool and moist enough for the plants to gather sufficient water from the soil to form the starchy tubers. Potatoes do not keep very well in storage and are vulnerable to moulds that feed on the stored tubers and quickly turn them rotten, whereas crops such as grain can be stored for several years with a low risk of rot. The yield of Calories per acre (about 9.2 million) is higher than that of maize (7.5 million), rice (7.4 million), wheat (3 million), or soybean (2.8 million).
VARIETIES
There are close to 4,000 varieties of potato including common commercial varieties, each of which has specific agricultural or culinary attributes. Around 80 varieties are commercially available in the UK. In general, varieties are categorized into a few main groups based on common characteristics, such as russet potatoes (rough brown skin), red potatoes, white potatoes, yellow potatoes (also called Yukon potatoes) and purple potatoes.
For culinary purposes, varieties are often differentiated by their waxiness: floury or mealy baking potatoes have more starch (20–22%) than waxy boiling potatoes (16–18%). The distinction may also arise from variation in the comparative ratio of two different potato starch compounds: amylose and amylopectin. Amylose, a long-chain molecule, diffuses from the starch granule when cooked in water, and lends itself to dishes where the potato is mashed. Varieties that contain a slightly higher amylopectin content, which is a highly branched molecule, help the potato retain its shape after being boiled in water. Potatoes that are good for making potato chips or potato crisps are sometimes called "chipping potatoes", which means they meet the basic requirements of similar varietal characteristics, being firm, fairly clean, and fairly well-shaped.
The European Cultivated Potato Database (ECPD) is an online collaborative database of potato variety descriptions that is updated and maintained by the Scottish Agricultural Science Agency within the framework of the European Cooperative Programme for Crop Genetic Resources Networks (ECP/GR)—which is run by the International Plant Genetic Resources Institute (IPGRI).
PIGMENTATION
Dozens of potato cultivars have been selectively bred specifically for their skin or, more commonly, flesh color, including gold, red, and blue varieties that contain varying amounts of phytochemicals, including carotenoids for gold/yellow or polyphenols for red or blue cultivars. Carotenoid compounds include provitamin A alpha-carotene and beta-carotene, which are converted to the essential nutrient, vitamin A, during digestion. Anthocyanins mainly responsible for red or blue pigmentation in potato cultivars do not have nutritional significance, but are used for visual variety and consumer appeal. Recently, as of 2010, potatoes have also been bioengineered specifically for these pigmentation traits.
GENETICALLY ENGINEERED POTATOES
Genetic research has produced several genetically modified varieties. 'New Leaf', owned by Monsanto Company, incorporates genes from Bacillus thuringiensis, which confers resistance to the Colorado potato beetle; 'New Leaf Plus' and 'New Leaf Y', approved by US regulatory agencies during the 1990s, also include resistance to viruses. McDonald's, Burger King, Frito-Lay, and Procter & Gamble announced they would not use genetically modified potatoes, and Monsanto published its intent to discontinue the line in March 2001.
Waxy potato varieties produce two main kinds of potato starch, amylose and amylopectin, the latter of which is most industrially useful. BASF developed the Amflora potato, which was modified to express antisense RNA to inactivate the gene for granule bound starch synthase, an enzyme which catalyzes the formation of amylose. Amflora potatoes therefore produce starch consisting almost entirely of amylopectin, and are thus more useful for the starch industry. In 2010, the European Commission cleared the way for 'Amflora' to be grown in the European Union for industrial purposes only—not for food. Nevertheless, under EU rules, individual countries have the right to decide whether they will allow this potato to be grown on their territory. Commercial planting of 'Amflora' was expected in the Czech Republic and Germany in the spring of 2010, and Sweden and the Netherlands in subsequent years. Another GM potato variety developed by BASF is 'Fortuna' which was made resistant to late blight by adding two resistance genes, blb1 and blb2, which originate from the Mexican wild potato Solanum bulbocastanum. In October 2011 BASF requested cultivation and marketing approval as a feed and food from the EFSA. In 2012, GMO development in Europe was stopped by BASF.
In November 2014, the USDA approved a genetically modified potato developed by J.R. Simplot Company, which contains genetic modifications that prevent bruising and produce less acrylamide when fried than conventional potatoes; the modifications do not cause new proteins to be made, but rather prevent proteins from being made via RNA interference.
HISTORY
The potato was first domesticated in the region of modern-day southern Peru and extreme northwestern Bolivia between 8000 and 5000 BC. It has since spread around the world and become a staple crop in many countries.
The earliest archaeologically verified potato tuber remains have been found at the coastal site of Ancon (central Peru), dating to 2500 BC. The most widely cultivated variety, Solanum tuberosum tuberosum, is indigenous to the Chiloé Archipelago, and has been cultivated by the local indigenous people since before the Spanish conquest.
According to conservative estimates, the introduction of the potato was responsible for a quarter of the growth in Old World population and urbanization between 1700 and 1900. In the Altiplano, potatoes provided the principal energy source for the Inca civilization, its predecessors, and its Spanish successor. Following the Spanish conquest of the Inca Empire, the Spanish introduced the potato to Europe in the second half of the 16th century, part of the Columbian exchange. The staple was subsequently conveyed by European mariners to territories and ports throughout the world. The potato was slow to be adopted by European farmers, but soon enough it became an important food staple and field crop that played a major role in the European 19th century population boom. However, lack of genetic diversity, due to the very limited number of varieties initially introduced, left the crop vulnerable to disease. In 1845, a plant disease known as late blight, caused by the fungus-like oomycete Phytophthora infestans, spread rapidly through the poorer communities of western Ireland as well as parts of the Scottish Highlands, resulting in the crop failures that led to the Great Irish Famine. Thousands of varieties still persist in the Andes however, where over 100 cultivars might be found in a single valley, and a dozen or more might be maintained by a single agricultural household.
PRODUCTION
In 2016, world production of potatoes was 377 million tonnes, led by China with over 26% of the world total (see table). Other major producers were India, Russia, Ukraine and the United States. It remains an essential crop in Europe (especially eastern and central Europe), where per capita production is still the highest in the world, but the most rapid expansion over the past few decades has occurred in southern and eastern Asia.
NUTRITION
A raw potato is 79% water, 17% carbohydrates (88% is starch), 2% protein, and contains negligible fat (see table). In an amount measuring 100 grams, raw potato provides 322 kilojoules (77 kilocalories) of energy and is a rich source of vitamin B6 and vitamin C (23% and 24% of the Daily Value, respectively), with no other vitamins or minerals in significant amount (see table). The potato is rarely eaten raw because raw potato starch is poorly digested by humans. When a potato is baked, its contents of vitamin B6 and vitamin C decline notably, while there is little significant change in the amount of other nutrients.
Potatoes are often broadly classified as having a high glycemic index (GI) and so are often excluded from the diets of individuals trying to follow a low-GI diet. The GI of potatoes can vary considerably depending on the cultivar or cultivar category (such as "red", russet, "white", or King Edward), growing conditions and storage, preparation methods (by cooking method, whether it is eaten hot or cold, whether it is mashed or cubed or consumed whole), and accompanying foods consumed (especially the addition of various high-fat or high-protein toppings). In particular, consuming reheated or cooled potatoes that were previously cooked may yield a lower GI effect.
In the UK, potatoes are not considered by the National Health Service (NHS) as counting or contributing towards the recommended daily five portions of fruit and vegetables, the 5-A-Day program.
COMPARISON TO OTHER STAPLE FOODS
This table shows the nutrient content of potatoes next to other major staple foods, each one measured in its respective raw state, even though staple foods are not commonly eaten raw and are usually sprouted or cooked before eating. In sprouted and cooked form, the relative nutritional and anti-nutritional contents of each of these grains (or other foods) may be different from the values in this table. Each nutrient (every row) has the highest number highlighted to show the staple food with the greatest amount in a 100-gram raw portion.
TOXICITY
Potatoes contain toxic compounds known as glycoalkaloids, of which the most prevalent are solanine and chaconine. Solanine is found in other plants in the same family, Solanaceae, which includes such plants as deadly nightshade (Atropa belladonna), henbane (Hyoscyamus niger) and tobacco (Nicotiana spp.), as well as the food plants eggplant and tomato. These compounds, which protect the potato plant from its predators, are generally concentrated in its leaves, flowers, sprouts, and fruits (in contrast to the tubers). In a summary of several studies, the glycoalkaloid content was highest in the flowers and sprouts and lowest in the tuber flesh. (The glycoalkaloid content was, in order from highest to lowest: flowers, sprouts, leaves, skin, roots, berries, peel [skin plus outer cortex of tuber flesh], stems, and tuber flesh.)
Exposure to light, physical damage, and age increase glycoalkaloid content within the tuber. Cooking at high temperatures—over 170 °C—partly destroys these compounds. The concentration of glycoalkaloids in wild potatoes is sufficient to produce toxic effects in humans. Glycoalkaloid poisoning may cause headaches, diarrhea, cramps, and, in severe cases, coma and death. However, poisoning from cultivated potato varieties is very rare. Light exposure causes greening from chlorophyll synthesis, giving a visual clue as to which areas of the tuber may have become more toxic. However, this does not provide a definitive guide, as greening and glycoalkaloid accumulation can occur independently of each other.
Different potato varieties contain different levels of glycoalkaloids. The Lenape variety was released in 1967 but was withdrawn in 1970 as it contained high levels of glycoalkaloids. Since then, breeders developing new varieties test for this, and sometimes have to discard an otherwise promising cultivar. Breeders try to keep glycoalkaloid levels below 200 mg/kg). However, when these commercial varieties turn green, they can still approach solanine concentrations of 1000 mg/kg. In normal potatoes, analysis has shown solanine levels may be as little as 3.5% of the breeders' maximum, with 7–187 mg/kg being found. While a normal potato tuber has 12–20 mg/kg of glycoalkaloid content, a green potato tuber contains 250–280 mg/kg and its skin has 1500–2200 mg/kg.
GROWTH AND CULTIVATION
SEED POTATOES
Potatoes are generally grown from seed potatoes, tubers specifically grown to be free from disease and to provide consistent and healthy plants. To be disease free, the areas where seed potatoes are grown are selected with care. In the US, this restricts production of seed potatoes to only 15 states out of all 50 states where potatoes are grown. These locations are selected for their cold, hard winters that kill pests and summers with long sunshine hours for optimum growth. In the UK, most seed potatoes originate in Scotland, in areas where westerly winds prevent aphid attack and thus prevent spread of potato virus pathogens.
PHASES OF GROWTH
Potato growth is divided into five phases. During the first phase, sprouts emerge from the seed potatoes and root growth begins. During the second, photosynthesis begins as the plant develops leaves and branches. In the third phase, stolons develop from lower leaf axils on the stem and grow downwards into the ground and on these stolons new tubers develop as swellings of the stolon. This phase is often, but not always, associated with flowering. Tuber formation halts when soil temperatures reach 27 °C; hence potatoes are considered a cool-season, or winter, crop. Tuber bulking occurs during the fourth phase, when the plant begins investing the majority of its resources in its newly formed tubers. At this phase, several factors are critical to a good yield: optimal soil moisture and temperature, soil nutrient availability and balance, and resistance to pest attacks. The fifth and final phase is the maturation of the tubers: the plant canopy dies back, the tuber skins harden, and the sugars in the tubers convert to starches.
CHALLENGES
New tubers may start growing at the surface of the soil. Since exposure to light leads to an undesirable greening of the skins and the development of solanine as a protection from the sun's rays, growers cover surface tubers. Commercial growers cover them by piling additional soil around the base of the plant as it grows (called "hilling" up, or in British English "earthing up"). An alternative method, used by home gardeners and smaller-scale growers, involves covering the growing area with organic mulches such as straw or plastic sheets.
Correct potato husbandry can be an arduous task in some circumstances. Good ground preparation, harrowing, plowing, and rolling are always needed, along with a little grace from the weather and a good source of water. Three successive plowings, with associated harrowing and rolling, are desirable before planting. Eliminating all root-weeds is desirable in potato cultivation. In general, the potatoes themselves are grown from the eyes of another potato and not from seed. Home gardeners often plant a piece of potato with two or three eyes in a hill of mounded soil. Commercial growers plant potatoes as a row crop using seed tubers, young plants or microtubers and may mound the entire row. Seed potato crops are rogued in some countries to eliminate diseased plants or those of a different variety from the seed crop.
Potatoes are sensitive to heavy frosts, which damage them in the ground. Even cold weather makes potatoes more susceptible to bruising and possibly later rotting, which can quickly ruin a large stored crop.
PESTS
The historically significant Phytophthora infestans (late blight) remains an ongoing problem in Europe and the United States. Other potato diseases include Rhizoctonia, Sclerotinia, black leg, powdery mildew, powdery scab and leafroll virus.
Insects that commonly transmit potato diseases or damage the plants include the Colorado potato beetle, the potato tuber moth, the green peach aphid (Myzus persicae), the potato aphid, beet leafhoppers, thrips, and mites. The potato cyst nematode is a microscopic worm that thrives on the roots, thus causing the potato plants to wilt. Since its eggs can survive in the soil for several years, crop rotation is recommended.
During the crop year 2008, many of the certified organic potatoes produced in the United Kingdom and certified by the Soil Association as organic were sprayed with a copper pesticide to control potato blight (Phytophthora infestans). According to the Soil Association, the total copper that can be applied to organic land is 6 kg/ha/year.
According to an Environmental Working Group analysis of USDA and FDA pesticide residue tests performed from 2000 through 2008, 84% of the 2,216 tested potato samples contained detectable traces of at least one pesticide. A total of 36 unique pesticides were detected on potatoes over the 2,216 samples, though no individual sample contained more than 6 unique pesticide traces, and the average was 1.29 detectable unique pesticide traces per sample. The average quantity of all pesticide traces found in the 2,216 samples was 1.602 ppm. While this was a very low value of pesticide residue, it was the highest amongst the 50 vegetables analyzed.
HARVEST
At harvest time, gardeners usually dig up potatoes with a long-handled, three-prong "grape" (or graip), i.e., a spading fork, or a potato hook, which is similar to the graip but with tines at a 90° angle to the handle. In larger plots, the plow is the fastest implement for unearthing potatoes. Commercial harvesting is typically done with large potato harvesters, which scoop up the plant and surrounding earth. This is transported up an apron chain consisting of steel links several feet wide, which separates some of the dirt. The chain deposits into an area where further separation occurs. Different designs use different systems at this point. The most complex designs use vine choppers and shakers, along with a blower system to separate the potatoes from the plant. The result is then usually run past workers who continue to sort out plant material, stones, and rotten potatoes before the potatoes are continuously delivered to a wagon or truck. Further inspection and separation occurs when the potatoes are unloaded from the field vehicles and put into storage.
Immature potatoes may be sold as "creamer potatoes" and are particularly valued for taste. These are often harvested by the home gardener or farmer by "grabbling", i.e. pulling out the young tubers by hand while leaving the plant in place. A creamer potato is a variety of potato harvested before it matures to keep it small and tender. It is generally either a Yukon Gold potato or a red potato, called gold creamers or red creamers respectively, and measures approximately 2.5 cm in diameter. The skin of creamer potatoes is waxy and high in moisture content, and the flesh contains a lower level of starch than other potatoes. Like potatoes in general, they can be prepared by boiling, baking, frying, and roasting. Slightly older than creamer potatoes are "new potatoes", which are also prized for their taste and texture and often come from the same varieties.
Potatoes are usually cured after harvest to improve skin-set. Skin-set is the process by which the skin of the potato becomes resistant to skinning damage. Potato tubers may be susceptible to skinning at harvest and suffer skinning damage during harvest and handling operations. Curing allows the skin to fully set and any wounds to heal. Wound-healing prevents infection and water-loss from the tubers during storage. Curing is normally done at relatively warm temperatures 10 to 16 °C with high humidity and good gas-exchange if at all possible.
STORAGE
Storage facilities need to be carefully designed to keep the potatoes alive and slow the natural process of decomposition, which involves the breakdown of starch. It is crucial that the storage area is dark, ventilated well and, for long-term storage, maintained at temperatures near 4 °C. For short-term storage, temperatures of about 7 to 10 °C are preferred.
On the other hand, temperatures below 4 °C convert the starch in potatoes into sugar, which alters their taste and cooking qualities and leads to higher acrylamide levels in the cooked product, especially in deep-fried dishes. The discovery of acrylamides in starchy foods in 2002 has led to international health concerns. They are believed to be probable carcinogens and their occurrence in cooked foods is being studied for potentially influencing health problems.
Under optimum conditions in commercial warehouses, potatoes can be stored for up to 10–12 months. The commercial storage and retrieval of potatoes involves several phases: first drying surface moisture; wound healing at 85% to 95% relative humidity and temperatures below 25 °C; a staged cooling phase; a holding phase; and a reconditioning phase, during which the tubers are slowly warmed. Mechanical ventilation is used at various points during the process to prevent condensation and the accumulation of carbon dioxide.
When stored in homes unrefrigerated, the shelf life is usually a few weeks.
If potatoes develop green areas or start to sprout, trimming or peeling those green-colored parts is inadequate to remove copresent toxins, and such potatoes are no longer edible.
YIELD
The world dedicated 18.6 million ha in 2010 for potato cultivation. The average world farm yield for potato was 17.4 tonnes per hectare, in 2010. Potato farms in the United States were the most productive in 2010, with a nationwide average of 44.3 tonnes per hectare. United Kingdom was a close second.
New Zealand farmers have demonstrated some of the best commercial yields in the world, ranging between 60 and 80 tonnes per hectare, some reporting yields of 88 tonnes potatoes per hectare.
There is a big gap among various countries between high and low yields, even with the same variety of potato. Average potato yields in developed economies ranges between 38–44 tonnes per hectare. China and India accounted for over a third of world's production in 2010, and had yields of 14.7 and 19.9 tonnes per hectare respectively. The yield gap between farms in developing economies and developed economies represents an opportunity loss of over 400 million tonnes of potato, or an amount greater than 2010 world potato production. Potato crop yields are determined by factors such as the crop breed, seed age and quality, crop management practices and the plant environment. Improvements in one or more of these yield determinants, and a closure of the yield gap, can be a major boost to food supply and farmer incomes in the developing world.
USES
Potatoes are prepared in many ways: skin-on or peeled, whole or cut up, with seasonings or without. The only requirement involves cooking to swell the starch granules. Most potato dishes are served hot but some are first cooked, then served cold, notably potato salad and potato chips (crisps). Common dishes are: mashed potatoes, which are first boiled (usually peeled), and then mashed with milk or yogurt and butter; whole baked potatoes; boiled or steamed potatoes; French-fried potatoes or chips; cut into cubes and roasted; scalloped, diced, or sliced and fried (home fries); grated into small thin strips and fried (hash browns); grated and formed into dumplings, Rösti or potato pancakes. Unlike many foods, potatoes can also be easily cooked in a microwave oven and still retain nearly all of their nutritional value, provided they are covered in ventilated plastic wrap to prevent moisture from escaping; this method produces a meal very similar to a steamed potato, while retaining the appearance of a conventionally baked potato. Potato chunks also commonly appear as a stew ingredient. Potatoes are boiled between 10 and 25 minutes, depending on size and type, to become soft.
OTHER THAN FOR EATING
Potatoes are also used for purposes other than eating by humans, for example:
Potatoes are used to brew alcoholic beverages such as vodka, poitín, or akvavit.
They are also used as fodder for livestock. Livestock-grade potatoes, considered too small and/or blemished to sell or market for human use but suitable for fodder use, have been called chats in some dialects. They may be stored in bins until use; they are sometimes ensiled. Some farmers prefer to steam them rather than feed them raw and are equipped to do so efficiently.
Potato starch is used in the food industry as a thickener and binder for soups and sauces, in the textile industry as an adhesive, and for the manufacturing of papers and boards.
Maine companies are exploring the possibilities of using waste potatoes to obtain polylactic acid for use in plastic products; other research projects seek ways to use the starch as a base for biodegradable packaging.
Potato skins, along with honey, are a folk remedy for burns in India. Burn centres in India have experimented with the use of the thin outer skin layer to protect burns while healing.
Potatoes (mainly Russets) are commonly used in plant research. The consistent parenchyma tissue, the clonal nature of the plant and the low metabolic activity provide a very nice "model tissue" for experimentation. Wound-response studies are often done on potato tuber tissue, as are electron transport experiments. In this respect, potato tuber tissue is similar to Drosophila melanogaster, Caenorhabditis elegans and Escherichia coli: they are all "standard" research organisms.
Potatoes have been delivered with personalized messages as a novelty. Potato delivery services include Potato Parcel and Mail A Spud.
WIKIPEDIA
My wife and I were travelling from South Africa to Kenya.
We were lucky enough to visit a Himba tribe. The people were beautiful and had their own distinctive style. The women and children would put red mud on their skin and in their hair for the pigmentation.

Littorina compressa Jeffreys, 1865
Synonyms:
Littorina nigrolineata Philippi, 1846, and most other authors until 1995 (not Littorina nigrolineata Gray, 1839 = banded var. of L. saxatilis sensu stricto); Littorina rudis var. nigrolineata Forbes & Hanley, 1850 (not Gray); Littorina rudis var. sulcata Jeffreys, 1865; Littorina rudis var. compressa Jeffreys, 1865; Littorina saxatilis nigrolineata McMillan, 1939 & 1944 (not Gray, 1839).
See Reid (1996) for more complete synonymy and his reasons why the long established name, Littorina nigrolineata Gray, 1839, should not be applied to L. compressa.
Current taxonomy: World Register of Marine Species (WoRMS)
www.marinespecies.org/aphia.php?p=taxdetails&id=140260
Vernacular: Black-lined periwinkle (confusing name as L. saxatilis s.s. and L. arcana have black-lined forms, and many L. compressa lack black lines).
GLOSSARY BELOW
Introduction
This is the easiest species to identify in the Littorina saxatilis s.l. complex in Britain, Ireland and Brittany. The population of var. barentica in northern Norway and the Murman coast of Arctic Russia has a different appearance and is not included in this account; description can be found in Reid (1996). Some Littorina specimens in Iberia resemble L. compressa in some respects , but all are considered by Reid (1996) to be L. saxatilis s.s.; they too are excluded from this account, except for purpose of comparison.
Shell Description
Mature shell height 3.6 to 23mm, many don’t mature until over 6mm. Adults often have thick shell-wall 1Lc flic.kr/p/q596xT ; juvenile shells are usually thin 2Lc flic.kr/p/pMWCmc . Outer layer calcite, inner layers aragonite. Moderately high spire with pointed apex; bodywhorl 75% to 90% of shell-height. Rounded whorls; separated by sutures that are not deeply recessed. No umbilicus. Aperture oval, of varying roundness, sometimes a slight basal spout, especially on juveniles 2Lc flic.kr/p/pMWCmc . Adapical angle almost 90º 1Lc flic.kr/p/q596xT . Outer lip slightly crenulated by grooves on outer surface, more markedly on thin walled specimens 2Lc flic.kr/p/pMWCmc . Columellar lip wide. Substantial glaze on body-whorl forms parietal lip. When shell-walls thick, interior of aperture usually paler; narrows rapidly inwards to brown throat. Sculpture usually of broad, flat-topped or gently-curved, strap-like, spiral ribs separated by narrow, deeply incised grooves 3Lc flic.kr/p/q5rHTL . Ribs bear spiral microstriae and often a medial, shallow, secondary groove 4Lc flic.kr/p/q5iHCp . Actively growing juveniles to about 6mm high often have spiral bands slightly more angulated than on adults 2Lc flic.kr/p/pMWCmc, somewhat resembling other species in L. saxatilis complex 5Lc flic.kr/p/q3dpnQ . Ground colour yellow 3Lc flic.kr/p/q5rHTL , or white 6Lc flic.kr/p/Sg8nYG shading through cream to pale yellow 7Lc flic.kr/p/S64ejG , occasionally grey , blackish or reddish 8Lc flic.kr/p/SjNKtt . On some shores, 100% have dark-brown 3Lc flic.kr/p/q5rHTL , black 7Lc flic.kr/p/S64ejG or purple-black spiral lines, nearly always confined to grooves between the ribs (= nigrolineate, var. sulcata, Jeffreys); palatal lip, if thick, may have round, dark marks at ends of grooves 1Lc flic.kr/p/q596xT . Other shores have 100% with no dark lines ( var. compressa, Jeffreys). It seems that few shores have a mixture with intergrading of the two forms 7Lc flic.kr/p/S64ejG . On rare individuals, dark pigment spreads beyond grooves and grades into the ground colour to form broad bands 9Lc flic.kr/p/R37Fsf . Columellar lip usually pure white untinted by any other colour, but occasionally brown 9Lc flic.kr/p/R37Fsf & 10Lc flic.kr/p/R5MFST . The barnacle ecotype has bands (R. Key) flic.kr/p/bCHKxW or tessellation and is so similar to the barnacle ecotypes of L. saxatilis and L. arcana 45Lc flic.kr/p/WkVqHD that examination of genitalia is needed to differentiate them. Colours and features such as glaze of parietal lip may be obscured by epibiota or detritus 9Lc flic.kr/p/R37Fsf . Periostracum imperceptible. Operculum ovoid spiral, variable shades of translucent brown, sometimes with a fine black speckling 11Lc flic.kr/p/R37Eiw .
Body Description
Head black or grey dorsally 12Lc flic.kr/p/R37E79 ; snout is unpigmented whitish or yellowish at its tip and ventrally 13Lc flic.kr/p/R5MERe . Large reddish buccal mass shows laterally through pale area to posterior of eyes 13Lc flic.kr/p/R5MERe and through dorsum of head if pigmentation is not intense 14Lc flic.kr/p/p8yTQr ; pinkish odontophore with radula visible in open mouth when feeding 15Lc flic.kr/p/pMWBDR . Cephalic tentacles taper rapidly from greatly swollen base bearing eye 15Lc flic.kr/p/pMWBDR ; translucent yellowish-white with pair of blackish dorsolateral lines 12Lc flic.kr/p/R37E79 . Black dorsolateral lines on tentacles may expand laterally along wrinkles to form short traverse lines 17Lc flic.kr/p/q594pK , sometimes dorsolateral lines so expanded that tentacles are almost entirely blackish 18Lc flic.kr/p/Sg8j85 . Body translucency varies with presence/intensity of black pigment behind head. Course of anterior aorta visible as long unpigmented band running diagonally across body to base of right tentacle 12Lc flic.kr/p/R37E79 & 14Lc flic.kr/p/p8yTQr . b>Radula much longer than body; accommodated in spiral radula sac that may be visible as whitish circle with pink centre in dorsum of body 14Lc flic.kr/p/p8yTQr . Mantle translucent yellowish or whitish near rim of aperture 18Lc flic.kr/p/Sg8j85 but pigmented dark grey or black further in where it forms the mantle cavity 19Lc flic.kr/p/R5MEmX . Greyish ctenidium within dark mantle cavity 20Lc flic.kr/p/SjNGYP .
Typically 3 to 8 large mamilliform glands (extremes 1 to 13) in a single row along ventral edge of penis (Reid, 1996) and (Naylor & Begon, 1982) 21Lc flic.kr/p/R5ME2t . Base of penis wrinkled. Filament of penis is triangular, sometimes somewhat mucronate 18Lc flic.kr/p/Sg8j85 , less than 5% of total length of penis. Distal and proximal faces of penis often entirely translucent yellowish white apart from opaque white subepithelial tissue in glands and distally around sperm groove 21Lc flic.kr/p/R5ME2t . Often distal face of penis has some grey or black pigment 13Lc flic.kr/p/R5MERe , occasionally covering basal half 22Lc flic.kr/p/S8CE5p . Some males have reduced penis size, possibly indicating out of breeding condition. Appearance of penis is affected by killing 21Lc flic.kr/p/R5ME2t . The Ovipositor on the right side of a female’s body extends to below the right eye; it is grey with longitudinal dark creases 23Lc flic.kr/p/SjNGCD and sometimes a yellow tip 16Lc flic.kr/p/pMYjby . The sole of the foot is pure white; it is divided into left and right halves by a medial line and has many transverse waves when in motion 24Lc flic.kr/p/q3dnQ1 . The upper surface of the foot is white 12Lc flic.kr/p/R37E79 , often with black or grey lines and speckles 25Lc flic.kr/p/S8CDUp & 26Lc flic.kr/p/Sg8hzW or unpigmented yellowish-white 27Lc flic.kr/p/q593i6 . The opercular disc does not enfold the edges of the operculum but it shifts position. It sometimes extends a little beyond the operculum 28Lc flic.kr/p/S648N1 and sometimes retracts to expose a little of the underside of the operculum 29Lc flic.kr/p/RK3JzA . The disc is whitish 30Lc flic.kr/p/R5MCA2 , sometimes with a yellowish perimeter 31Lc flic.kr/p/S8CDbR which shows through the translucent operculum 11Lc flic.kr/p/R37Eiw . The brown operculum is a lighter colour where about a third of it is attached to the opercular disc 11Lc flic.kr/p/R37Eiw .
Internal anatomy
If a live animal is induced to extend from its shell with the methods described in Smith (2016) (link in references) it should be possible to see the mantle cavity, head, tentacles, penis or ovipositor, foot, and, if its body is not too heavily pigmented, the buccal mass, radular sac, and course of the anterior aorta 14Lc flic.kr/p/p8yTQr .
If a specimen is killed and extracted from its shell (methods in section 4 of Smith, 2017), it should be possible, without further dissection to discern the mantle, osphradium, columellar muscle, posterior oesophagus, stomach and digestive gland 19Lc flic.kr/p/R5MEmX .
If the mantle is cut along its left side and folded back, further anatomical detail will be exposed, including a ribbed “ciliated field” 32Lc flic.kr/p/q5iES4 that was used for differentiation of Littorina species by Hannaford Ellis (1979). However, it is not an easy feature to examine, is considered unreliable (D. Reid, in litt.) and is not necessary for L. compressa specimens as they can be easily distinguished by their shells (Ellis, 1979).
If the body is cut open, the radula can be extracted. Its length varies from 110% to 277% of shell height (Reid, 1996). It is generally shorter than that of L. saxatilis s.s. and L. arcana, but there is large interspecific overlap and seasonal variation as the radula continues growth when wear from feeding ceases in winter.
Key identification features
Littorina compressa has most distinct shell of any species in Littorina saxatilis s.l. complex and can be reliably identified by its sculpture when over 6 mm high, except L. compressa var. barentica from northern Norway and the Murman Coast of Russia and which is not included below.

Habits and ecology
Lives on bedrock and boulders on upper shore in barnacle zone of exposed shores, and in Fucus spiralis zone and upper part of Fucus vesiculosus / Ascophyllum zone of more sheltered shores; usually lower on shore than L. saxatilis s.s. and L. arcana with some overlap 33Lc flic.kr/p/q3jJYS . Not often on algal fronds. Three ecotypes recognised: “moderate” from sheltered to moderately exposed shores, “wave exposed” from exposed shores, and “barnacle” living among barnacles and mussels on exposed shores (Reid, 1996).
Moderate ecotype populations on shores with Ballantine exposure grades 5 to 8, where crabs are common, usually grow larger (mature shells about 14 mm on average, up to 20 or 23 mm), have thicker shells and narrower apertures to resist crab intrusion. Wave exposed ecotype populations on shores with Ballantine grades 1 to 4 are smaller (up to 12 mm high) and usually have populations with thinner shells and wider apertures to accommodate larger feet for firmer grip. However, those on unstable boulders on exposed shores, with risk of boulder- crushing, have larger, thicker shells (mature at about 13 mm height) than those living in crevices of stable bedrock (mature at about 8 mm) on the same exposed shore (Naylor & Begon, 1982) 33Lc flic.kr/p/q3jJYS & 1Lc flic.kr/p/q596xT . The barnacle ecotype matures as small as 3.6 mm high, max. height 6mm and, as it lives on exposed shores, has short spire, thin shell and relatively large aperture too.
Of fifteen shores surveyed in Anglesey, nine mainly exposed shores had 100% lined shells, five mainly sheltered shores had 100% unlined shells, and only one (sheltered) shore had a mixture with some intergrading (Naylor & Begon, 1982). Population densities usually lower than of L. saxatilis s.s. and L. arcana; occasionally 5 – 30 per m² on favourable shores in Wales and Ireland, but up to 2000 per m² recorded in Brittany. Absent from saltings, but able to survive there in experiments; may need hard rock to attach spawn to. Sometimes at mouths of estuaries.
Locomotion by ditaxic retrograde waves on longitudinally divided sole. Bilaminate anterior edge contains anterior pedal gland that produces mucus for locomotion. No planktonic stage; dispersal by crawling; consequent low gene exchange contributes to maintenance of discrete populations of nigrolineate or plain shell forms on different shores.
Feeds on fucoid fronds where present, otherwise on algal sporelings, small epiphytic algae, unicellular algae and fragmented organic debris. Faeces expelled as pellets 26Lc flic.kr/p/Sg8hzW . Predators include crabs that especially consume larger specimens on sheltered shores where Carcina maenas Linnaeus is common. Rock pippets (Anthus spinoletta, Montagu) consume many juveniles, and probably have good colour vision that exerts selection pressure on less cryptic specimens. Shell outline is disrupted by black lines so nigrolineate form is well camouflaged on bare or barnacle-covered rocks. L. compressa is host to the larval forms of the parasitic trematode worms Microphallus pygmaeus Levinsen and M. similis Jägerskiold which have A. spinoletta and C. maenas, respectively, as their subsequent host.
Breeding reported all year with peak in N. Wales May to June, or winter to spring; probably varies geographically and with local weather conditions. Males inseminate females by inserting penis into mantle cavity; seem unable to distinguish females of own species from those of L. saxatilis s.s. as about 50% of observed copulation (or attempted copulation; release of spermatozoa could not be ascertained) by male L. compressa on an Anglesey shore was with female L. saxatilis s.s. or males of either species (Raffaelli, 1997). Females are oviparous; spawn mass is gelatinous, pink or white, reniform to circular, about 5mm X 10mm X 3mm thick and contains 100 – 200 singly encapsulated ova. Spawn attached to rocky substrate in humid position e.g. under rock, crevice among barnacles or at base of Fucus. Veliger stage passed within egg; crawling, shelled young emerge. Juveniles under 7mm high usually have sloping ribs with a sharp raised edge, resembling other species in L. saxatilis complex.
Distribution and status
L. compressa var. typica Britain, Ireland, Normandy and Brittany. Absent from continental coast of North Sea apart from occasional individuals with imported oysters. Records of L. nigrolineata from Spain (Rolán, 1984) and Portugal (Burnay, 1986) are based on the Iberian black-lined form of L. saxatilis; L. compressa is absent (Reid, 1996) GBIF map www.gbif.org/species/4361986
Absent from N.E. Irish Sea, and E. England from R. Tyne to Sussex. Greatest concentrations are in W. Cornwall, S.W. & N.W. Wales, S. & W. Wales, W. Scotland and Orkney. Small barnacle-ecotype recorded only in S.W. Wales and W. Ireland. Some British and Irish records are probably mistaken identifications of lined forms of L. saxatilis s.s.. NBN U.K. interactive distribution map of “L. nigrolineata Gray” is probably mainly of L. compressa, but Reid (1996) expressed doubt about and omitted south coast England records east of Cornwall from his distribution map; validation with specimens or clear photographs desirable NBN Map species.nbnatlas.org/species/NHMSYS0021055459
The rare L. compressa var. barentica is found from northern Norway (Narvik) to Murman coast of Arctic Russia; its shell is usually entirely brown, thin-walled, tall-spired and lacks flat strap-like ribs. Fuller details in Reid (1996). No single convincing ecological reason has been advanced for the patchy distribution. Colonization is probably retarded by the lack of planktonic dispersal as the young pass the veliger stage in the egg.

The pomegranate (/ˈpɒmᵻɡrænᵻt/), botanical name Punica granatum, is a fruit-bearing deciduous shrub or small tree growing between 5 and 8 m tall.
In the Northern Hemisphere, the fruit is typically in season from September to February, and in the Southern Hemisphere from March to May. As intact arils or juice, pomegranates are used in cooking, baking, meal garnishes, juice blends, smoothies, and alcoholic beverages, such as cocktails and wine.
The pomegranate originated in the region of modern-day Iran and has been cultivated since ancient times throughout the Mediterranean region and northern India. It was introduced into America (Spanish America) in the late 16th century and California by Spanish settlers in 1769.
Today, it is widely cultivated throughout the Middle East and Caucasus region, north Africa and tropical Africa, the Indian subcontinent, Central Asia, the drier parts of southeast Asia, and parts of the Mediterranean Basin. It is also cultivated in parts of California and Arizona. In recent years, it has become more common in the commercial markets of Europe and the Western Hemisphere.
ETYMOLOGY
The name pomegranate derives from medieval Latin pōmum "apple" and grānātum "seeded". Perhaps stemming from the old French word for the fruit, pomme-grenade, the pomegranate was known in early English as "apple of Grenada" - a term which today survives only in heraldic blazons. This is a folk etymology, confusing Latin granatus with the name of the Spanish city of Granada, which derives from Arabic.
Garnet derives from Old French grenat by metathesis, from Medieval Latin granatum as used in a different meaning "of a dark red color". This derivation may have originated from pomum granatum describing the color of pomegranate pulp or from granum referring to "red dye, cochineal".
The French term for pomegranate, grenade, has given its name to the military grenade.
DESCRIPTION
A shrub or small tree growing 6 to 10 m high, the pomegranate has multiple spiny branches, and is extremely long-lived, with some specimens in France surviving for 200 years. P. granatum leaves are opposite or subopposite, glossy, narrow oblong, entire, 3–7 cm long and 2 cm broad. The flowers are bright red and 3 cm in diameter, with three to seven petals. Some fruitless varieties are grown for the flowers alone.
The edible fruit is a berry, intermediate in size between a lemon and a grapefruit, 5–12 cm in diameter with a rounded shape and thick, reddish skin. The number of seeds in a pomegranate can vary from 200 to about 1400. Each seed has a surrounding water-laden pulp — the edible sarcotesta that forms from the seed coat — ranging in color from white to deep red or purple. The seeds are "exarillate", i.e., unlike some other species in the order, Myrtales, no aril is present. The sarcotesta of pomegranate seeds consists of epidermis cells derived from the integument. The seeds are embedded in a white, spongy, astringent membrane.
CULTIVATION
P. granatum is grown for its fruit crop, and as ornamental trees and shrubs in parks and gardens. Mature specimens can develop sculptural twisted-bark multiple trunks and a distinctive overall form. Pomegranates are drought-tolerant, and can be grown in dry areas with either a Mediterranean winter rainfall climate or in summer rainfall climates. In wetter areas, they can be prone to root decay from fungal diseases. They can be tolerant of moderate frost, down to about −12 °C.
Insect pests of the pomegranate can include the pomegranate butterfly Virachola isocrates and the leaf-footed bug Leptoglossus zonatus, and fruit flies and ants are attracted to unharvested ripe fruit. Pomegranate grows easily from seed, but is commonly propagated from 25– to 50-cm hardwood cuttings to avoid the genetic variation of seedlings. Air layering is also an option for propagation, but grafting fails.
VARIETIES
P. granatum var. nana is a dwarf variety of P. granatum popularly planted as an ornamental plant in gardens and larger containers, and used as a bonsai specimen tree. It could well be a wild form with a distinct origin. It has gained the Royal Horticultural Society's Award of Garden Merit. The only other species in the genus Punica is the Socotran pomegranate (P. protopunica), which is endemic to the island of Socotra. It differs in having pink (not red) flowers and smaller, less sweet fruit.
CULTIVARS
P. granatum has more than 500 named cultivars, but evidently has considerable synonymy in which the same genotype is named differently across regions of the world.[15]
Several characteristics between pomegranate genotypes vary for identification, consumer preference, preferred use, and marketing, the most important of which are fruit size, exocarp color (ranging from yellow to purple, with pink and red most common), seed-coat color (ranging from white to red), hardness of seed, maturity, juice content and its acidity, sweetness, and astringency.
CULTURAL HISTORY
Pomegranate is native to a region from Iran to northern India. Pomegranates have been cultivated throughout the Middle East, South Asia, and Mediterranean region for several millennia, and also thrive in the drier climates of California and Arizona.
Carbonized exocarp of the fruit has been identified in early Bronze Age levels of Jericho in the West Bank, as well as late Bronze Age levels of Hala Sultan Tekke on Cyprus and Tiryns.[citation needed] A large, dry pomegranate was found in the tomb of Djehuty, the butler of Queen Hatshepsut in Egypt; Mesopotamian cuneiform records mention pomegranates from the mid-third millennium BC onwards.
It is also extensively grown in South China and in Southeast Asia, whether originally spread along the route of the Silk Road or brought by sea traders. Kandahar is famous in Afghanistan for its high-quality pomegranates.
Although not native to Korea or Japan, the pomegranate is widely grown there and many cultivars have been developed. It is widely used for bonsai because of its flowers and for the unusual twisted bark the older specimens can attain. The term "balaustine" (Latin: balaustinus) is also used for a pomegranate-red color.
The ancient city of Granada in Spain was renamed after the fruit during the Moorish period and today the province of Granada uses pomegranate as a charge in heraldry for its canting arms.
Spanish colonists later introduced the fruit to the Caribbean and America (Spanish America), but in the English colonies, it was less at home: "Don't use the pomegranate inhospitably, a stranger that has come so far to pay his respects to thee," the English Quaker Peter Collinson wrote to the botanizing John Bartram in Philadelphia, 1762. "Plant it against the side of thy house, nail it close to the wall. In this manner it thrives wonderfully with us, and flowers beautifully, and bears fruit this hot year. I have twenty-four on one tree... Doctor Fothergill says, of all trees this is most salutiferous to mankind."
The pomegranate had been introduced as an exotic to England the previous century, by John Tradescant the elder, but the disappointment that it did not set fruit there led to its repeated introduction to the American colonies, even New England. It succeeded in the South: Bartram received a barrel of pomegranates and oranges from a correspondent in Charleston, South Carolina, 1764. John Bartram partook of "delitious" pomegranates with Noble Jones at Wormsloe Plantation, near Savannah, Georgia, in September 1765. Thomas Jefferson planted pomegranates at Monticello in 1771: he had them from George Wythe of Williamsburg.
CULINARY USE
After the pomegranate is opened by scoring it with a knife and breaking it open, the seeds are separated from the peel and internal white pulp membranes. Separating the seeds is easier in a bowl of water because the seeds sink and the inedible pulp floats. Freezing the entire fruit also makes it easier to separate. Another effective way of quickly harvesting the seeds is to cut the pomegranate in half, score each half of the exterior rind four to six times, hold the pomegranate half over a bowl, and smack the rind with a large spoon. The seeds should eject from the pomegranate directly into the bowl, leaving only a dozen or more deeply embedded seeds to remove. The entire seed is consumed raw, though the watery, tasty sarcotesta is the desired part. The taste differs depending on the variety or cultivar of pomegranate and its ripeness.
Pomegranate juice can be sweet or sour, but most fruits are moderate in taste, with sour notes from the acidic tannins contained in the juice. Pomegranate juice has long been a popular drink in Europe, the Middle East and is now widely distributed in the United States and Canada.
Grenadine syrup long ago consisted of thickened and sweetened pomegranate juice, now is usually a sales name for a syrup based on various berries, citric acid, and food coloring, mainly used in cocktail mixing. In Europe, Bols still manufactures grenadine syrup with pomegranate. Before tomatoes, a New World fruit, arrived in the Middle East, pomegranate juice, molasses, and vinegar were widely used in many Iranian foods, and are still found in traditional recipes such as fesenjān, a thick sauce made from pomegranate juice and ground walnuts, usually spooned over duck or other poultry and rice, and in ash-e anar (pomegranate soup).
Pomegranate seeds are used as a spice known as anardana (from Persian: anar + dana, pomegranate + seed), most notably in Indian and Pakistani cuisine. Dried whole seeds can often be obtained in ethnic Indian subcontinent markets. These seeds are separated from the flesh, dried for 10–15 days, and used as an acidic agent for chutney and curry preparation. Ground anardana is also used, which results in a deeper flavoring in dishes and prevents the seeds from getting stuck in teeth. Seeds of the wild pomegranate variety known as daru from the Himalayas are regarded as quality sources for this spice.
Dried pomegranate seeds, found in some natural specialty food markets, still contain some residual water, maintaining a natural sweet and tart flavor. Dried seeds can be used in several culinary applications, such as trail mix, granola bars, or as a topping for salad, yogurt, or ice cream.
In the Caucasus, pomegranate is used mainly for juice. In Azerbaijan, a sauce from pomegranate juice narsharab, (from Persian: (a)nar + sharab, lit. "pomegranate wine") is usually served with fish or tika kabab. In Turkey, pomegranate sauce (Turkish: nar ekşisi) is used as a salad dressing, to marinate meat, or simply to drink straight. Pomegranate seeds are also used in salads and sometimes as garnish for desserts such as güllaç. Pomegranate syrup or molasses is used in muhammara, a roasted red pepper, walnut, and garlic spread popular in Syria and Turkey.
In Greece, pomegranate (Greek: ρόδι, rodi) is used in many recipes, including kollivozoumi, a creamy broth made from boiled wheat, pomegranates, and raisins, legume salad with wheat and pomegranate, traditional Middle Eastern lamb kebabs with pomegranate glaze, pomegranate eggplant relish, and avocado-pomegranate dip. Pomegranate is also made into a liqueur, and as a popular fruit confectionery used as ice cream topping, mixed with yogurt, or spread as jam on toast. In Cyprus and Greece, and among the Greek Orthodox Diaspora, ρόδι (Greek for pomegranate) is used to make koliva, a mixture of wheat, pomegranate seeds, sugar, almonds, and other seeds served at memorial services.
In Mexico, they are commonly used to adorn the traditional dish chiles en nogada, representing the red of the Mexican flag in the dish which evokes the green (poblano pepper), white (nogada sauce) and red (pomegranate seeds) tricolor.
IN TRADITIONAL MEDICINE
In the Indian subcontinent's ancient Ayurveda system of traditional medicine, the pomegranate is frequently described as an ingredient in remedies.
In folk medicine pomegranate has been thought a contraceptive and abortifacient when the seeds or rind are eaten, or when as a vaginal suppository.
NUTRITION
A 100-g serving of pomegranate seeds provides 12% of the Daily Value (DV) for vitamin C, 16% DV for vitamin K and 10% DV for folate (table).
Pomegranate seeds are an excellent source of dietary fiber (20% DV) which is entirely contained in the edible seeds. People who choose to discard the seeds forfeit nutritional benefits conveyed by the seed fiber and micronutrients.
Pomegranate seed oil contains punicic acid (65.3%), palmitic acid (4.8%), stearic acid (2.3%), oleic acid (6.3%), and linoleic acid (6.6%).
RESEARCH
JUICE
The most abundant phytochemicals in pomegranate juice are polyphenols, including the hydrolyzable tannins called ellagitannins formed when ellagic acid and/or gallic acid binds with a carbohydrate to form pomegranate ellagitannins, also known as punicalagins.
The red color of juice can be attributed to anthocyanins, such as delphinidin, cyanidin, and pelargonidin glycosides. Generally, an increase in juice pigmentation occurs during fruit ripening.
The phenolic content of pomegranate juice is adversely affected by processing and pasteurization techniques.
PEEL
Compared to the pulp, the inedible pomegranate peel contains as much as three times the total amount of polyphenols, including condensed tannins, catechins, gallocatechins and prodelphinidins.
The higher phenolic content of the peel yields extracts for use in dietary supplements and food preservatives.
Health claims
Despite limited research data, manufacturers and marketers of pomegranate juice have liberally used evolving research results for product promotion. In February 2010, the FDA issued a Warning Letter to one such manufacturer, POM Wonderful, for using published literature to make illegal claims of unproven anti-disease benefits.
SYMBOLISM
ANCIENT EGYPT
Ancient Egyptians regarded the pomegranate as a symbol of prosperity and ambition. According to the Ebers Papyrus, one of the oldest medical writings from around 1500 BC, Egyptians used the pomegranate for treatment of tapeworm and other infections.
ANCIENT GREECE
The Greeks were familiar with the fruit far before it was introduced to Rome via Carthage. In Ancient Greek mythology, the pomegranate was known as the "fruit of the dead", and believed to have sprung from the blood of Adonis.
The myth of Persephone, the goddess of the underworld, prominently features the pomegranate. In one version of Greek mythology, Persephone was kidnapped by Hades and taken off to live in the underworld as his wife. Her mother, Demeter (goddess of the Harvest), went into mourning for her lost daughter, thus all green things ceased to grow. Zeus, the highest-ranking of the Greek gods, could not allow the Earth to die, so he commanded Hades to return Persephone. It was the rule of the Fates that anyone who consumed food or drink in the underworld was doomed to spend eternity there. Persephone had no food, but Hades tricked her into eating six pomegranate seeds while she was still his prisoner, so she was condemned to spend six months in the underworld every year. During these six months, while Persephone sits on the throne of the underworld beside her husband Hades, her mother Demeter mourns and no longer gives fertility to the earth. This was an ancient Greek explanation for the seasons. Dante Gabriel Rossetti's painting Persephona depicts Persephone holding the fatal fruit. The number of seeds Persephone ate varies, depending on which version of the story is told. The number ranges from three to seven, which accounts for just one barren season if it is just three or four seeds, or two barren seasons (half the year) if she ate six or seven seeds.
The pomegranate also evoked the presence of the Aegean Triple Goddess who evolved into the Olympian Hera, who is sometimes represented offering the pomegranate, as in the Polykleitos' cult image of the Argive Heraion (see below). According to Carl A. P. Ruck and Danny Staples, the chambered pomegranate is also a surrogate for the poppy's narcotic capsule, with its comparable shape and chambered interior. On a Mycenaean seal illustrated in Joseph Campbell's Occidental Mythology 1964, figure 19, the seated Goddess of the double-headed axe (the labrys) offers three poppy pods in her right hand and supports her breast with her left. She embodies both aspects of the dual goddess, life-giving and death-dealing at once. The Titan Orion was represented as "marrying" Side, a name that in Boeotia means "pomegranate", thus consecrating the primal hunter to the Goddess. Other Greek dialects call the pomegranate rhoa; its possible connection with the name of the earth goddess Rhea, inexplicable in Greek, proved suggestive for the mythographer Karl Kerenyi, who suggested the consonance might ultimately derive from a deeper, pre-Indo-European language layer.
In the 5th century BC, Polycleitus took ivory and gold to sculpt the seated Argive Hera in her temple. She held a scepter in one hand and offered a pomegranate, like a 'royal orb', in the other. "About the pomegranate I must say nothing," whispered the traveller Pausanias in the 2nd century, "for its story is somewhat of a holy mystery." In the Orion story, Hera cast pomegranate-Side (an ancient city in Antalya) into dim Erebus — "for daring to rival Hera's beauty", which forms the probable point of connection with the older Osiris/Isis story.[citation needed] Since the ancient Egyptians identified the Orion constellation in the sky as Sah the "soul of Osiris", the identification of this section of the myth seems relatively complete. Hera wears, not a wreath nor a tiara nor a diadem, but clearly the calyx of the pomegranate that has become her serrated crown.[citation needed] The pomegranate has a calyx shaped like a crown. In Jewish tradition, it has been seen as the original "design" for the proper crown. In some artistic depictions, the pomegranate is found in the hand of Mary, mother of Jesus.
A pomegranate is displayed on coins from the ancient city of Side, Pamphylia.
Within the Heraion at the mouth of the Sele, near Paestum, Magna Graecia, is a chapel devoted to the Madonna del Granato, "Our Lady of the Pomegranate", "who by virtue of her epithet and the attribute of a pomegranate must be the Christian successor of the ancient Greek goddess Hera", observes the excavator of the Heraion of Samos, Helmut Kyrieleis.
In modern times, the pomegranate still holds strong symbolic meanings for the Greeks. On important days in the Greek Orthodox calendar, such as the Presentation of the Virgin Mary and on Christmas Day, it is traditional to have at the dinner table polysporia, also known by their ancient name panspermia, in some regions of Greece. In ancient times, they were offered to Demeter[citation needed] and to the other gods for fertile land, for the spirits of the dead and in honor of compassionate Dionysus.[citation needed] When one buys a new home, it is conventional for a house guest to bring as a first gift a pomegranate, which is placed under/near the ikonostasi (home altar) of the house, as a symbol of abundance, fertility, and good luck. Pomegranates are also prominent at Greek weddings and funerals.[citation needed] When Greeks commemorate their dead, they make kollyva as offerings, which consist of boiled wheat, mixed with sugar and decorated with pomegranate. It is also traditional in Greece to break a pomegranate on the ground at weddings and on New Years. Pomegranate decorations for the home are very common in Greece and sold in most home goods stores.
ANCIENT ISRAEL AND JUDAISM
Pomegranates were known in Ancient Israel as the fruits which the scouts brought to Moses to demonstrate the fertility of the "promised land". The Book of Exodus describes the me'il ("robe of the ephod") worn by the Hebrew high priest as having pomegranates embroidered on the hem alternating with golden bells which could be heard as the high priest entered and left the Holy of Holies. According to the Books of Kings, the capitals of the two pillars (Jachin and Boaz) that stood in front of Solomon's Temple in Jerusalem were engraved with pomegranates. Solomon is said to have designed his coronet based on the pomegranate's "crown" (calyx).
It is traditional to consume pomegranates on Rosh Hashana because, with its numerous seeds, it symbolizes fruitfulness. Also, it is said to have 613 seeds, which corresponds with the 613 mitzvot or commandments of the Torah.[61] This particular tradition is referred to in the opening pages of Ursula Dubosarsky's novel Theodora's Gift.
The pomegranate appeared on the ancient coins of Judea. When not in use, the handles of Torah scrolls are sometimes covered with decorative silver globes similar in shape to "pomegranates" (rimmonim). Some Jewish scholars believe the pomegranate was the forbidden fruit in the Garden of Eden.[60] Pomegranates are one of the Seven Species (Hebrew: שבעת המינים, Shiv'at Ha-Minim) of fruits and grains enumerated in the Hebrew Bible (Deuteronomy 8:8) as being special products of the Land of Israel. The pomegranate is mentioned in the Bible many times, including this quote from the Songs of Solomon, "Thy lips are like a thread of scarlet, and thy speech is comely: thy temples are like a piece of a pomegranate within thy locks." (Song of Solomon 4:3). Pomegranates also symbolize the mystical experience in the Jewish mystical tradition, or kabbalah, with the typical reference being to entering the "garden of pomegranates" or pardes rimonim; this is also the title of a book by the 16th-century mystic Moses ben Jacob Cordovero.
IN EUROPEAN CHRISTIAN MOTIFS
In the earliest incontrovertible appearance of Christ in a mosaic, a 4th-century floor mosaic from Hinton St Mary, Dorset, now in the British Museum, the bust of Christ and the chi rho are flanked by pomegranates. Pomegranates continue to be a motif often found in Christian religious decoration. They are often woven into the fabric of vestments and liturgical hangings or wrought in metalwork. Pomegranates figure in many religious paintings by the likes of Sandro Botticelli and Leonardo da Vinci, often in the hands of the Virgin Mary or the infant Jesus. The fruit, broken or bursting open, is a symbol of the fullness of Jesus' suffering and resurrection.
In the Eastern Orthodox Church, pomegranate seeds may be used in kolyva, a dish prepared for memorial services, as a symbol of the sweetness of the heavenly kingdom.
IN THE QUR´AN
According to the Qur'an, pomegranates grow in the gardens of paradise (55:68). The Qur'an also mentions pomegranates three times.(6:99, 6:141, 55:68)
AFGHANISTAN
Pomegranate, a favorite fall and winter fruit in Afghanistan, has mainly two varieties: one that is sweet and dark red with hard seeds growing in and around Kandhar province, and the other that has soft seeds with variable color growing in the central/northern region. The largest market for Afghan pomegranates is India followed by Pakistan, Russia, United Arab Emirates and Europe.
ARMENIA
The pomegranate is one of the main fruits in Armenian culture (the others being apricot and grapes). Its juice is famous with Armenians in food and heritage. The pomegranate is the symbol of Armenia and represents fertility, abundance and marriage. For example, the fruit played an integral role in a wedding custom widely practiced in ancient Armenia: a bride was given a pomegranate fruit, which she threw against a wall, breaking it into pieces. Scattered pomegranate seeds ensured the bride future children. In Karabakh, it was customary to put fruits next to the bridal couple during the first night of marriage, among them the pomegranate, which was said to ensure happiness. It is likely that newlyweds also enjoyed pomegranate wine. The symbolism of the pomegranate is that it protected a woman from infertility and protected a man's virility. Both homemade and commercial wine is made from pomegranate in Armenia. The Color of Pomegranates (1969) is a movie directed by Sergei Parajanov. It is a biography of the Armenian ashug Sayat-Nova (King of Song) which attempts to reveal the poet's life visually and poetically rather than literally.
AZERBAIJAN
Pomegranate is considered one of the symbols of Azerbaijan. Annually in October, a cultural festival is held in Goychay, Azerbaijan known as the Goychay Pomegranate Festival. The festival features Azerbaijani fruit-cuisine mainly the pomegranates from Goychay, which is famous for its pomegranate growing industry. At the festival, a parade is held with traditional Azerbaijani dances and Azerbaijani music. Pomegranate was depicted on the official logo of the 2015 European Games held in Azerbaijan. Nar the Pomegranate was one of the two mascots of these games. Pomegranates also featured on the jackets worn by Azerbaijani male athletes at the games' opening ceremony.
IRAN AND ANCIENT PERSIA
Pomegranate was the symbol of fertility in ancient Persian culture.[citation needed] In Persian mythology, Isfandiyar eats a pomegranate and becomes invincible. In the Greco-Persian Wars, Herodotus mentions golden pomegranates adorning the spears of warriors in the phalanx. Even in today's Iran, pomegranate may imply love and fertility.
Iran produces pomegranates as a common crop.[citation needed] Its juice and paste have a role in some Iranian cuisines, e.g. chicken, ghormas and refreshment bars. Pomegranate skins may be used to stain wool and silk in the carpet industry.
Pomegranate Festival is an annual cultural and artistic festival held during October in Tehran[citation needed] to exhibit and sell pomegranates, food products and handicrafts.
PAKISTAN
The pomegranate (known as "anār" in Urdu) is a popular fruit in Pakistan. It is grown in Pakistan and is also imported from Afghanistan.
INDIA
In some Hindu traditions, the pomegranate (Hindi: anār) symbolizes prosperity and fertility, and is associated with both Bhoomidevi (the earth goddess) and Lord Ganesha (the one fond of the many-seeded fruit). The Tamil name maadulampazham is a metaphor for a woman's mind. It is derived from, maadhu=woman, ullam=mind, which means as the seeds are hidden, it is not easy to decipher a woman's mind.
CHINA
Introduced to China during the Tang Dynasty (618-907 AD), the pomegranate (Chinese: 石榴; pinyin: shíliu) in olden times was considered an emblem of fertility and numerous progeny. This symbolism is a pun on the Chinese character 子 (zǐ) which, as well as meaning seed, also means "offspring" thus a fruit containing so many seeds is a sign of fecundity. Pictures of the ripe fruit with the seeds bursting forth were often hung in homes to bestow fertility and bless the dwelling with numerous offspring, an important facet of traditional Chinese culture.
WIKIPEDIA
The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. In many contexts, potato refers to the edible tuber, but it can also refer to the plant itself. Common or slang terms include tater, tattie and spud. Potatoes were introduced to Europe in the second half of the 16th century by the Spanish. Today they are a staple food in many parts of the world and an integral part of much of the world's food supply. As of 2014, potatoes were the world's fourth-largest food crop after maize (corn), wheat, and rice.
Wild potato species can be found throughout the Americas, from the United States to southern Chile. The potato was originally believed to have been domesticated independently in multiple locations, but later genetic testing of the wide variety of cultivars and wild species traced a single origin for potatoes. In the area of present-day southern Peru and extreme northwestern Bolivia, from a species in the Solanum brevicaule complex, potatoes were domesticated approximately 7,000–10,000 years ago. In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated.
Following millennia of selective breeding, there are now over 1,000 different types of potatoes. Over 99% of presently cultivated potatoes worldwide descended from varieties that originated in the lowlands of south-central Chile, which have displaced formerly popular varieties from the Andes.
The importance of the potato as a food source and culinary ingredient varies by region and is still changing. It remains an essential crop in Europe, especially eastern and central Europe, where per capita production is still the highest in the world, while the most rapid expansion in production over the past few decades has occurred in southern and eastern Asia, with China and India leading the world in overall production as of 2014.
Being a nightshade similar to tomatoes, the vegetative and fruiting parts of the potato contain the toxin solanine and are not fit for human consumption. Normal potato tubers that have been grown and stored properly produce glycoalkaloids in amounts small enough to be negligible to human health, but if green sections of the plant (namely sprouts and skins) are exposed to light, the tuber can accumulate a high enough concentration of glycoalkaloids to affect human health.
ETYMOLOGY
The English word potato comes from Spanish patata (the name used in Spain). The Spanish Royal Academy says the Spanish word is a hybrid of the Taíno batata (sweet potato) and the Quechua papa (potato). The name originally referred to the sweet potato although the two plants are not closely related. The 16th-century English herbalist John Gerard referred to sweet potatoes as "common potatoes", and used the terms "bastard potatoes" and "Virginia potatoes" for the species we now call "potato". In many of the chronicles detailing agriculture and plants, no distinction is made between the two. Potatoes are occasionally referred to as "Irish potatoes" or "white potatoes" in the United States, to distinguish them from sweet potatoes.
The name spud for a small potato comes from the digging of soil (or a hole) prior to the planting of potatoes. The word has an unknown origin and was originally (c. 1440) used as a term for a short knife or dagger, probably related to the Latin "spad-" a word root meaning "sword"; cf. Spanish "espada", English "spade" and "spadroon". It subsequently transferred over to a variety of digging tools. Around 1845, the name transferred to the tuber itself, the first record of this usage being in New Zealand English. The origin of the word "spud" has erroneously been attributed to an 18th-century activist group dedicated to keeping the potato out of Britain, calling itself The Society for the Prevention of Unwholesome Diet (S.P.U.D.). It was Mario Pei's 1949 The Story of Language that can be blamed for the word's false origin. Pei writes, "the potato, for its part, was in disrepute some centuries ago. Some Englishmen who did not fancy potatoes formed a Society for the Prevention of Unwholesome Diet. The initials of the main words in this title gave rise to spud." Like most other pre-20th century acronymic origins, this is false, and there is no evidence that a Society for the Prevention of Unwholesome Diet ever existed.
CHARACTERISTICS
Potato plants are herbaceous perennials that grow about 60 cm high, depending on variety, with the leaves dying back after flowering, fruiting and tuber formation. They bear white, pink, red, blue, or purple flowers with yellow stamens. In general, the tubers of varieties with white flowers have white skins, while those of varieties with colored flowers tend to have pinkish skins. Potatoes are mostly cross-pollinated by insects such as bumblebees, which carry pollen from other potato plants, though a substantial amount of self-fertilizing occurs as well. Tubers form in response to decreasing day length, although this tendency has been minimized in commercial varieties.
After flowering, potato plants produce small green fruits that resemble green cherry tomatoes, each containing about 300 seeds. Like all parts of the plant except the tubers, the fruit contain the toxic alkaloid solanine and are therefore unsuitable for consumption. All new potato varieties are grown from seeds, also called "true potato seed", "TPS" or "botanical seed" to distinguish it from seed tubers. New varieties grown from seed can be propagated vegetatively by planting tubers, pieces of tubers cut to include at least one or two eyes, or cuttings, a practice used in greenhouses for the production of healthy seed tubers. Plants propagated from tubers are clones of the parent, whereas those propagated from seed produce a range of different varieties.
GENETICS
There are about 5,000 potato varieties worldwide. Three thousand of them are found in the Andes alone, mainly in Peru, Bolivia, Ecuador, Chile, and Colombia. They belong to eight or nine species, depending on the taxonomic school. Apart from the 5,000 cultivated varieties, there are about 200 wild species and subspecies, many of which can be cross-bred with cultivated varieties. Cross-breeding has been done repeatedly to transfer resistances to certain pests and diseases from the gene pool of wild species to the gene pool of cultivated potato species. Genetically modified varieties have met public resistance in the United States and in the European UnionThe major species grown worldwide is Solanum tuberosum (a tetraploid with 48 chromosomes), and modern varieties of this species are the most widely cultivated. There are also four diploid species (with 24 chromosomes): S. stenotomum, S. phureja, S. goniocalyx, and S. ajanhuiri. There are two triploid species (with 36 chromosomes): S. chaucha and S. juzepczukii. There is one pentaploid cultivated species (with 60 chromosomes): S. curtilobum. There are two major subspecies of Solanum tuberosum: andigena, or Andean; and tuberosum, or Chilean. The Andean potato is adapted to the short-day conditions prevalent in the mountainous equatorial and tropical regions where it originated; the Chilean potato, however, native to the Chiloé Archipelago, is adapted to the long-day conditions prevalent in the higher latitude region of southern Chile.
The International Potato Center, based in Lima, Peru, holds an ISO-accredited collection of potato germplasm. The international Potato Genome Sequencing Consortium announced in 2009 that they had achieved a draft sequence of the potato genome. The potato genome contains 12 chromosomes and 860 million base pairs, making it a medium-sized plant genome. More than 99 percent of all current varieties of potatoes currently grown are direct descendants of a subspecies that once grew in the lowlands of south-central Chile. Nonetheless, genetic testing of the wide variety of cultivars and wild species affirms that all potato subspecies derive from a single origin in the area of present-day southern Peru and extreme Northwestern Bolivia (from a species in the Solanum brevicaule complex). The wild Crop Wild Relatives Prebreeding project encourages the use of wild relatives in breeding programs. Enriching and preserving the gene bank collection to make potatoes adaptive to diverse environmental conditions is seen as a pressing issue due to climate change.
Most modern potatoes grown in North America arrived through European settlement and not independently from the South American sources, although at least one wild potato species, Solanum fendleri, naturally ranges from Peru into Texas, where it is used in breeding for resistance to a nematode species that attacks cultivated potatoes. A secondary center of genetic variability of the potato is Mexico, where important wild species that have been used extensively in modern breeding are found, such as the hexaploid Solanum demissum, as a source of resistance to the devastating late blight disease. Another relative native to this region, Solanum bulbocastanum, has been used to genetically engineer the potato to resist potato blight.
Potatoes yield abundantly with little effort, and adapt readily to diverse climates as long as the climate is cool and moist enough for the plants to gather sufficient water from the soil to form the starchy tubers. Potatoes do not keep very well in storage and are vulnerable to moulds that feed on the stored tubers and quickly turn them rotten, whereas crops such as grain can be stored for several years with a low risk of rot. The yield of Calories per acre (about 9.2 million) is higher than that of maize (7.5 million), rice (7.4 million), wheat (3 million), or soybean (2.8 million).
VARIETIES
There are close to 4,000 varieties of potato including common commercial varieties, each of which has specific agricultural or culinary attributes. Around 80 varieties are commercially available in the UK. In general, varieties are categorized into a few main groups based on common characteristics, such as russet potatoes (rough brown skin), red potatoes, white potatoes, yellow potatoes (also called Yukon potatoes) and purple potatoes.
For culinary purposes, varieties are often differentiated by their waxiness: floury or mealy baking potatoes have more starch (20–22%) than waxy boiling potatoes (16–18%). The distinction may also arise from variation in the comparative ratio of two different potato starch compounds: amylose and amylopectin. Amylose, a long-chain molecule, diffuses from the starch granule when cooked in water, and lends itself to dishes where the potato is mashed. Varieties that contain a slightly higher amylopectin content, which is a highly branched molecule, help the potato retain its shape after being boiled in water. Potatoes that are good for making potato chips or potato crisps are sometimes called "chipping potatoes", which means they meet the basic requirements of similar varietal characteristics, being firm, fairly clean, and fairly well-shaped.
The European Cultivated Potato Database (ECPD) is an online collaborative database of potato variety descriptions that is updated and maintained by the Scottish Agricultural Science Agency within the framework of the European Cooperative Programme for Crop Genetic Resources Networks (ECP/GR)—which is run by the International Plant Genetic Resources Institute (IPGRI).
PIGMENTATION
Dozens of potato cultivars have been selectively bred specifically for their skin or, more commonly, flesh color, including gold, red, and blue varieties that contain varying amounts of phytochemicals, including carotenoids for gold/yellow or polyphenols for red or blue cultivars. Carotenoid compounds include provitamin A alpha-carotene and beta-carotene, which are converted to the essential nutrient, vitamin A, during digestion. Anthocyanins mainly responsible for red or blue pigmentation in potato cultivars do not have nutritional significance, but are used for visual variety and consumer appeal. Recently, as of 2010, potatoes have also been bioengineered specifically for these pigmentation traits.
GENETICALLY ENGINEERED POTATOES
Genetic research has produced several genetically modified varieties. 'New Leaf', owned by Monsanto Company, incorporates genes from Bacillus thuringiensis, which confers resistance to the Colorado potato beetle; 'New Leaf Plus' and 'New Leaf Y', approved by US regulatory agencies during the 1990s, also include resistance to viruses. McDonald's, Burger King, Frito-Lay, and Procter & Gamble announced they would not use genetically modified potatoes, and Monsanto published its intent to discontinue the line in March 2001.
Waxy potato varieties produce two main kinds of potato starch, amylose and amylopectin, the latter of which is most industrially useful. BASF developed the Amflora potato, which was modified to express antisense RNA to inactivate the gene for granule bound starch synthase, an enzyme which catalyzes the formation of amylose. Amflora potatoes therefore produce starch consisting almost entirely of amylopectin, and are thus more useful for the starch industry. In 2010, the European Commission cleared the way for 'Amflora' to be grown in the European Union for industrial purposes only—not for food. Nevertheless, under EU rules, individual countries have the right to decide whether they will allow this potato to be grown on their territory. Commercial planting of 'Amflora' was expected in the Czech Republic and Germany in the spring of 2010, and Sweden and the Netherlands in subsequent years. Another GM potato variety developed by BASF is 'Fortuna' which was made resistant to late blight by adding two resistance genes, blb1 and blb2, which originate from the Mexican wild potato Solanum bulbocastanum. In October 2011 BASF requested cultivation and marketing approval as a feed and food from the EFSA. In 2012, GMO development in Europe was stopped by BASF.
In November 2014, the USDA approved a genetically modified potato developed by J.R. Simplot Company, which contains genetic modifications that prevent bruising and produce less acrylamide when fried than conventional potatoes; the modifications do not cause new proteins to be made, but rather prevent proteins from being made via RNA interference.
HISTORY
The potato was first domesticated in the region of modern-day southern Peru and extreme northwestern Bolivia between 8000 and 5000 BC. It has since spread around the world and become a staple crop in many countries.
The earliest archaeologically verified potato tuber remains have been found at the coastal site of Ancon (central Peru), dating to 2500 BC. The most widely cultivated variety, Solanum tuberosum tuberosum, is indigenous to the Chiloé Archipelago, and has been cultivated by the local indigenous people since before the Spanish conquest.
According to conservative estimates, the introduction of the potato was responsible for a quarter of the growth in Old World population and urbanization between 1700 and 1900. In the Altiplano, potatoes provided the principal energy source for the Inca civilization, its predecessors, and its Spanish successor. Following the Spanish conquest of the Inca Empire, the Spanish introduced the potato to Europe in the second half of the 16th century, part of the Columbian exchange. The staple was subsequently conveyed by European mariners to territories and ports throughout the world. The potato was slow to be adopted by European farmers, but soon enough it became an important food staple and field crop that played a major role in the European 19th century population boom. However, lack of genetic diversity, due to the very limited number of varieties initially introduced, left the crop vulnerable to disease. In 1845, a plant disease known as late blight, caused by the fungus-like oomycete Phytophthora infestans, spread rapidly through the poorer communities of western Ireland as well as parts of the Scottish Highlands, resulting in the crop failures that led to the Great Irish Famine. Thousands of varieties still persist in the Andes however, where over 100 cultivars might be found in a single valley, and a dozen or more might be maintained by a single agricultural household.
PRODUCTION
In 2016, world production of potatoes was 377 million tonnes, led by China with over 26% of the world total (see table). Other major producers were India, Russia, Ukraine and the United States. It remains an essential crop in Europe (especially eastern and central Europe), where per capita production is still the highest in the world, but the most rapid expansion over the past few decades has occurred in southern and eastern Asia.
NUTRITION
A raw potato is 79% water, 17% carbohydrates (88% is starch), 2% protein, and contains negligible fat (see table). In an amount measuring 100 grams, raw potato provides 322 kilojoules (77 kilocalories) of energy and is a rich source of vitamin B6 and vitamin C (23% and 24% of the Daily Value, respectively), with no other vitamins or minerals in significant amount (see table). The potato is rarely eaten raw because raw potato starch is poorly digested by humans. When a potato is baked, its contents of vitamin B6 and vitamin C decline notably, while there is little significant change in the amount of other nutrients.
Potatoes are often broadly classified as having a high glycemic index (GI) and so are often excluded from the diets of individuals trying to follow a low-GI diet. The GI of potatoes can vary considerably depending on the cultivar or cultivar category (such as "red", russet, "white", or King Edward), growing conditions and storage, preparation methods (by cooking method, whether it is eaten hot or cold, whether it is mashed or cubed or consumed whole), and accompanying foods consumed (especially the addition of various high-fat or high-protein toppings). In particular, consuming reheated or cooled potatoes that were previously cooked may yield a lower GI effect.
In the UK, potatoes are not considered by the National Health Service (NHS) as counting or contributing towards the recommended daily five portions of fruit and vegetables, the 5-A-Day program.
COMPARISON TO OTHER STAPLE FOODS
This table shows the nutrient content of potatoes next to other major staple foods, each one measured in its respective raw state, even though staple foods are not commonly eaten raw and are usually sprouted or cooked before eating. In sprouted and cooked form, the relative nutritional and anti-nutritional contents of each of these grains (or other foods) may be different from the values in this table. Each nutrient (every row) has the highest number highlighted to show the staple food with the greatest amount in a 100-gram raw portion.
TOXICITY
Potatoes contain toxic compounds known as glycoalkaloids, of which the most prevalent are solanine and chaconine. Solanine is found in other plants in the same family, Solanaceae, which includes such plants as deadly nightshade (Atropa belladonna), henbane (Hyoscyamus niger) and tobacco (Nicotiana spp.), as well as the food plants eggplant and tomato. These compounds, which protect the potato plant from its predators, are generally concentrated in its leaves, flowers, sprouts, and fruits (in contrast to the tubers). In a summary of several studies, the glycoalkaloid content was highest in the flowers and sprouts and lowest in the tuber flesh. (The glycoalkaloid content was, in order from highest to lowest: flowers, sprouts, leaves, skin, roots, berries, peel [skin plus outer cortex of tuber flesh], stems, and tuber flesh.)
Exposure to light, physical damage, and age increase glycoalkaloid content within the tuber. Cooking at high temperatures—over 170 °C—partly destroys these compounds. The concentration of glycoalkaloids in wild potatoes is sufficient to produce toxic effects in humans. Glycoalkaloid poisoning may cause headaches, diarrhea, cramps, and, in severe cases, coma and death. However, poisoning from cultivated potato varieties is very rare. Light exposure causes greening from chlorophyll synthesis, giving a visual clue as to which areas of the tuber may have become more toxic. However, this does not provide a definitive guide, as greening and glycoalkaloid accumulation can occur independently of each other.
Different potato varieties contain different levels of glycoalkaloids. The Lenape variety was released in 1967 but was withdrawn in 1970 as it contained high levels of glycoalkaloids. Since then, breeders developing new varieties test for this, and sometimes have to discard an otherwise promising cultivar. Breeders try to keep glycoalkaloid levels below 200 mg/kg). However, when these commercial varieties turn green, they can still approach solanine concentrations of 1000 mg/kg. In normal potatoes, analysis has shown solanine levels may be as little as 3.5% of the breeders' maximum, with 7–187 mg/kg being found. While a normal potato tuber has 12–20 mg/kg of glycoalkaloid content, a green potato tuber contains 250–280 mg/kg and its skin has 1500–2200 mg/kg.
GROWTH AND CULTIVATION
SEED POTATOES
Potatoes are generally grown from seed potatoes, tubers specifically grown to be free from disease and to provide consistent and healthy plants. To be disease free, the areas where seed potatoes are grown are selected with care. In the US, this restricts production of seed potatoes to only 15 states out of all 50 states where potatoes are grown. These locations are selected for their cold, hard winters that kill pests and summers with long sunshine hours for optimum growth. In the UK, most seed potatoes originate in Scotland, in areas where westerly winds prevent aphid attack and thus prevent spread of potato virus pathogens.
PHASES OF GROWTH
Potato growth is divided into five phases. During the first phase, sprouts emerge from the seed potatoes and root growth begins. During the second, photosynthesis begins as the plant develops leaves and branches. In the third phase, stolons develop from lower leaf axils on the stem and grow downwards into the ground and on these stolons new tubers develop as swellings of the stolon. This phase is often, but not always, associated with flowering. Tuber formation halts when soil temperatures reach 27 °C; hence potatoes are considered a cool-season, or winter, crop. Tuber bulking occurs during the fourth phase, when the plant begins investing the majority of its resources in its newly formed tubers. At this phase, several factors are critical to a good yield: optimal soil moisture and temperature, soil nutrient availability and balance, and resistance to pest attacks. The fifth and final phase is the maturation of the tubers: the plant canopy dies back, the tuber skins harden, and the sugars in the tubers convert to starches.
CHALLENGES
New tubers may start growing at the surface of the soil. Since exposure to light leads to an undesirable greening of the skins and the development of solanine as a protection from the sun's rays, growers cover surface tubers. Commercial growers cover them by piling additional soil around the base of the plant as it grows (called "hilling" up, or in British English "earthing up"). An alternative method, used by home gardeners and smaller-scale growers, involves covering the growing area with organic mulches such as straw or plastic sheets.
Correct potato husbandry can be an arduous task in some circumstances. Good ground preparation, harrowing, plowing, and rolling are always needed, along with a little grace from the weather and a good source of water. Three successive plowings, with associated harrowing and rolling, are desirable before planting. Eliminating all root-weeds is desirable in potato cultivation. In general, the potatoes themselves are grown from the eyes of another potato and not from seed. Home gardeners often plant a piece of potato with two or three eyes in a hill of mounded soil. Commercial growers plant potatoes as a row crop using seed tubers, young plants or microtubers and may mound the entire row. Seed potato crops are rogued in some countries to eliminate diseased plants or those of a different variety from the seed crop.
Potatoes are sensitive to heavy frosts, which damage them in the ground. Even cold weather makes potatoes more susceptible to bruising and possibly later rotting, which can quickly ruin a large stored crop.
PESTS
The historically significant Phytophthora infestans (late blight) remains an ongoing problem in Europe and the United States. Other potato diseases include Rhizoctonia, Sclerotinia, black leg, powdery mildew, powdery scab and leafroll virus.
Insects that commonly transmit potato diseases or damage the plants include the Colorado potato beetle, the potato tuber moth, the green peach aphid (Myzus persicae), the potato aphid, beet leafhoppers, thrips, and mites. The potato cyst nematode is a microscopic worm that thrives on the roots, thus causing the potato plants to wilt. Since its eggs can survive in the soil for several years, crop rotation is recommended.
During the crop year 2008, many of the certified organic potatoes produced in the United Kingdom and certified by the Soil Association as organic were sprayed with a copper pesticide to control potato blight (Phytophthora infestans). According to the Soil Association, the total copper that can be applied to organic land is 6 kg/ha/year.
According to an Environmental Working Group analysis of USDA and FDA pesticide residue tests performed from 2000 through 2008, 84% of the 2,216 tested potato samples contained detectable traces of at least one pesticide. A total of 36 unique pesticides were detected on potatoes over the 2,216 samples, though no individual sample contained more than 6 unique pesticide traces, and the average was 1.29 detectable unique pesticide traces per sample. The average quantity of all pesticide traces found in the 2,216 samples was 1.602 ppm. While this was a very low value of pesticide residue, it was the highest amongst the 50 vegetables analyzed.
HARVEST
At harvest time, gardeners usually dig up potatoes with a long-handled, three-prong "grape" (or graip), i.e., a spading fork, or a potato hook, which is similar to the graip but with tines at a 90° angle to the handle. In larger plots, the plow is the fastest implement for unearthing potatoes. Commercial harvesting is typically done with large potato harvesters, which scoop up the plant and surrounding earth. This is transported up an apron chain consisting of steel links several feet wide, which separates some of the dirt. The chain deposits into an area where further separation occurs. Different designs use different systems at this point. The most complex designs use vine choppers and shakers, along with a blower system to separate the potatoes from the plant. The result is then usually run past workers who continue to sort out plant material, stones, and rotten potatoes before the potatoes are continuously delivered to a wagon or truck. Further inspection and separation occurs when the potatoes are unloaded from the field vehicles and put into storage.
Immature potatoes may be sold as "creamer potatoes" and are particularly valued for taste. These are often harvested by the home gardener or farmer by "grabbling", i.e. pulling out the young tubers by hand while leaving the plant in place. A creamer potato is a variety of potato harvested before it matures to keep it small and tender. It is generally either a Yukon Gold potato or a red potato, called gold creamers or red creamers respectively, and measures approximately 2.5 cm in diameter. The skin of creamer potatoes is waxy and high in moisture content, and the flesh contains a lower level of starch than other potatoes. Like potatoes in general, they can be prepared by boiling, baking, frying, and roasting. Slightly older than creamer potatoes are "new potatoes", which are also prized for their taste and texture and often come from the same varieties.
Potatoes are usually cured after harvest to improve skin-set. Skin-set is the process by which the skin of the potato becomes resistant to skinning damage. Potato tubers may be susceptible to skinning at harvest and suffer skinning damage during harvest and handling operations. Curing allows the skin to fully set and any wounds to heal. Wound-healing prevents infection and water-loss from the tubers during storage. Curing is normally done at relatively warm temperatures 10 to 16 °C with high humidity and good gas-exchange if at all possible.
STORAGE
Storage facilities need to be carefully designed to keep the potatoes alive and slow the natural process of decomposition, which involves the breakdown of starch. It is crucial that the storage area is dark, ventilated well and, for long-term storage, maintained at temperatures near 4 °C. For short-term storage, temperatures of about 7 to 10 °C are preferred.
On the other hand, temperatures below 4 °C convert the starch in potatoes into sugar, which alters their taste and cooking qualities and leads to higher acrylamide levels in the cooked product, especially in deep-fried dishes. The discovery of acrylamides in starchy foods in 2002 has led to international health concerns. They are believed to be probable carcinogens and their occurrence in cooked foods is being studied for potentially influencing health problems.
Under optimum conditions in commercial warehouses, potatoes can be stored for up to 10–12 months. The commercial storage and retrieval of potatoes involves several phases: first drying surface moisture; wound healing at 85% to 95% relative humidity and temperatures below 25 °C; a staged cooling phase; a holding phase; and a reconditioning phase, during which the tubers are slowly warmed. Mechanical ventilation is used at various points during the process to prevent condensation and the accumulation of carbon dioxide.
When stored in homes unrefrigerated, the shelf life is usually a few weeks.
If potatoes develop green areas or start to sprout, trimming or peeling those green-colored parts is inadequate to remove copresent toxins, and such potatoes are no longer edible.
YIELD
The world dedicated 18.6 million ha in 2010 for potato cultivation. The average world farm yield for potato was 17.4 tonnes per hectare, in 2010. Potato farms in the United States were the most productive in 2010, with a nationwide average of 44.3 tonnes per hectare. United Kingdom was a close second.
New Zealand farmers have demonstrated some of the best commercial yields in the world, ranging between 60 and 80 tonnes per hectare, some reporting yields of 88 tonnes potatoes per hectare.
There is a big gap among various countries between high and low yields, even with the same variety of potato. Average potato yields in developed economies ranges between 38–44 tonnes per hectare. China and India accounted for over a third of world's production in 2010, and had yields of 14.7 and 19.9 tonnes per hectare respectively. The yield gap between farms in developing economies and developed economies represents an opportunity loss of over 400 million tonnes of potato, or an amount greater than 2010 world potato production. Potato crop yields are determined by factors such as the crop breed, seed age and quality, crop management practices and the plant environment. Improvements in one or more of these yield determinants, and a closure of the yield gap, can be a major boost to food supply and farmer incomes in the developing world.
USES
Potatoes are prepared in many ways: skin-on or peeled, whole or cut up, with seasonings or without. The only requirement involves cooking to swell the starch granules. Most potato dishes are served hot but some are first cooked, then served cold, notably potato salad and potato chips (crisps). Common dishes are: mashed potatoes, which are first boiled (usually peeled), and then mashed with milk or yogurt and butter; whole baked potatoes; boiled or steamed potatoes; French-fried potatoes or chips; cut into cubes and roasted; scalloped, diced, or sliced and fried (home fries); grated into small thin strips and fried (hash browns); grated and formed into dumplings, Rösti or potato pancakes. Unlike many foods, potatoes can also be easily cooked in a microwave oven and still retain nearly all of their nutritional value, provided they are covered in ventilated plastic wrap to prevent moisture from escaping; this method produces a meal very similar to a steamed potato, while retaining the appearance of a conventionally baked potato. Potato chunks also commonly appear as a stew ingredient. Potatoes are boiled between 10 and 25 minutes, depending on size and type, to become soft.
OTHER THAN FOR EATING
Potatoes are also used for purposes other than eating by humans, for example:
Potatoes are used to brew alcoholic beverages such as vodka, poitín, or akvavit.
They are also used as fodder for livestock. Livestock-grade potatoes, considered too small and/or blemished to sell or market for human use but suitable for fodder use, have been called chats in some dialects. They may be stored in bins until use; they are sometimes ensiled. Some farmers prefer to steam them rather than feed them raw and are equipped to do so efficiently.
Potato starch is used in the food industry as a thickener and binder for soups and sauces, in the textile industry as an adhesive, and for the manufacturing of papers and boards.
Maine companies are exploring the possibilities of using waste potatoes to obtain polylactic acid for use in plastic products; other research projects seek ways to use the starch as a base for biodegradable packaging.
Potato skins, along with honey, are a folk remedy for burns in India. Burn centres in India have experimented with the use of the thin outer skin layer to protect burns while healing.
Potatoes (mainly Russets) are commonly used in plant research. The consistent parenchyma tissue, the clonal nature of the plant and the low metabolic activity provide a very nice "model tissue" for experimentation. Wound-response studies are often done on potato tuber tissue, as are electron transport experiments. In this respect, potato tuber tissue is similar to Drosophila melanogaster, Caenorhabditis elegans and Escherichia coli: they are all "standard" research organisms.
Potatoes have been delivered with personalized messages as a novelty. Potato delivery services include Potato Parcel and Mail A Spud.

This is a broad coverage reflectance spectrum of the rear abdomen (black arrow) of the blue damselfly that reaches far into the ultraviolet. Unlike the red damselfly, the blue colour here is a result of a partially ordered nanostructure (photonic crystal).
Until 2004, it was thought that this structural colour was the result of incoherent Tyndall (Rayleigh) scattering from structures within the integument of the animal.
More recent spectroscopy and electron microscopy ( journals.biologists.com/jeb/article/207/22/3999/15111/Blu... ) has shown that the colours are produced by arrays of closely packed arrays of nanoscale spheres within the endoplasmic reticulum of cells below the cuticle. These coherently scatter incoming light at a wavelength appropriate to the size and refractive index of the spheres which are only quasi-ordered, having a degree of disorder sufficient to remove the iridescence that would be observed in a more perfect structure.
Even more recent work has extended this model to show that this basic photonic structure can be modulated (polymorphism) by changes to the pterin pigmentation and refractive index within the nanospheres, allowing the animal to adjust its colour to suit different surroundings and activities ( dx.doi.org/10.1098/rsif.2018.0785 ).
This shows a mastery of the use a combination of both structural and pigment colour to produce a tuneable multi-purpose palette. This in some way echoes the possibilities applied by the octopus, cuttlefish and squid to change their body colours on much faster timescales
The spectra here were obtained with a Maya2000Pro (200 - 1100 nm) spectrometer using both halogen and deuterium lamps to provide the full wavelength coverage [note the excellent overlap of the different lamp measurements between 340 and 440 nm (red and purple lines superimposed)

The pomegranate (/ˈpɒmᵻɡrænᵻt/), botanical name Punica granatum, is a fruit-bearing deciduous shrub or small tree growing between 5 and 8 m tall.
In the Northern Hemisphere, the fruit is typically in season from September to February, and in the Southern Hemisphere from March to May. As intact arils or juice, pomegranates are used in cooking, baking, meal garnishes, juice blends, smoothies, and alcoholic beverages, such as cocktails and wine.
The pomegranate originated in the region of modern-day Iran and has been cultivated since ancient times throughout the Mediterranean region and northern India. It was introduced into America (Spanish America) in the late 16th century and California by Spanish settlers in 1769.
Today, it is widely cultivated throughout the Middle East and Caucasus region, north Africa and tropical Africa, the Indian subcontinent, Central Asia, the drier parts of southeast Asia, and parts of the Mediterranean Basin. It is also cultivated in parts of California and Arizona. In recent years, it has become more common in the commercial markets of Europe and the Western Hemisphere.
ETYMOLOGY
The name pomegranate derives from medieval Latin pōmum "apple" and grānātum "seeded". Perhaps stemming from the old French word for the fruit, pomme-grenade, the pomegranate was known in early English as "apple of Grenada" - a term which today survives only in heraldic blazons. This is a folk etymology, confusing Latin granatus with the name of the Spanish city of Granada, which derives from Arabic.
Garnet derives from Old French grenat by metathesis, from Medieval Latin granatum as used in a different meaning "of a dark red color". This derivation may have originated from pomum granatum describing the color of pomegranate pulp or from granum referring to "red dye, cochineal".
The French term for pomegranate, grenade, has given its name to the military grenade.
DESCRIPTION
A shrub or small tree growing 6 to 10 m high, the pomegranate has multiple spiny branches, and is extremely long-lived, with some specimens in France surviving for 200 years. P. granatum leaves are opposite or subopposite, glossy, narrow oblong, entire, 3–7 cm long and 2 cm broad. The flowers are bright red and 3 cm in diameter, with three to seven petals. Some fruitless varieties are grown for the flowers alone.
The edible fruit is a berry, intermediate in size between a lemon and a grapefruit, 5–12 cm in diameter with a rounded shape and thick, reddish skin. The number of seeds in a pomegranate can vary from 200 to about 1400. Each seed has a surrounding water-laden pulp — the edible sarcotesta that forms from the seed coat — ranging in color from white to deep red or purple. The seeds are "exarillate", i.e., unlike some other species in the order, Myrtales, no aril is present. The sarcotesta of pomegranate seeds consists of epidermis cells derived from the integument. The seeds are embedded in a white, spongy, astringent membrane.
CULTIVATION
P. granatum is grown for its fruit crop, and as ornamental trees and shrubs in parks and gardens. Mature specimens can develop sculptural twisted-bark multiple trunks and a distinctive overall form. Pomegranates are drought-tolerant, and can be grown in dry areas with either a Mediterranean winter rainfall climate or in summer rainfall climates. In wetter areas, they can be prone to root decay from fungal diseases. They can be tolerant of moderate frost, down to about −12 °C.
Insect pests of the pomegranate can include the pomegranate butterfly Virachola isocrates and the leaf-footed bug Leptoglossus zonatus, and fruit flies and ants are attracted to unharvested ripe fruit. Pomegranate grows easily from seed, but is commonly propagated from 25– to 50-cm hardwood cuttings to avoid the genetic variation of seedlings. Air layering is also an option for propagation, but grafting fails.
VARIETIES
P. granatum var. nana is a dwarf variety of P. granatum popularly planted as an ornamental plant in gardens and larger containers, and used as a bonsai specimen tree. It could well be a wild form with a distinct origin. It has gained the Royal Horticultural Society's Award of Garden Merit. The only other species in the genus Punica is the Socotran pomegranate (P. protopunica), which is endemic to the island of Socotra. It differs in having pink (not red) flowers and smaller, less sweet fruit.
CULTIVARS
P. granatum has more than 500 named cultivars, but evidently has considerable synonymy in which the same genotype is named differently across regions of the world.[15]
Several characteristics between pomegranate genotypes vary for identification, consumer preference, preferred use, and marketing, the most important of which are fruit size, exocarp color (ranging from yellow to purple, with pink and red most common), seed-coat color (ranging from white to red), hardness of seed, maturity, juice content and its acidity, sweetness, and astringency.
CULTURAL HISTORY
Pomegranate is native to a region from Iran to northern India. Pomegranates have been cultivated throughout the Middle East, South Asia, and Mediterranean region for several millennia, and also thrive in the drier climates of California and Arizona.
Carbonized exocarp of the fruit has been identified in early Bronze Age levels of Jericho in the West Bank, as well as late Bronze Age levels of Hala Sultan Tekke on Cyprus and Tiryns.[citation needed] A large, dry pomegranate was found in the tomb of Djehuty, the butler of Queen Hatshepsut in Egypt; Mesopotamian cuneiform records mention pomegranates from the mid-third millennium BC onwards.
It is also extensively grown in South China and in Southeast Asia, whether originally spread along the route of the Silk Road or brought by sea traders. Kandahar is famous in Afghanistan for its high-quality pomegranates.
Although not native to Korea or Japan, the pomegranate is widely grown there and many cultivars have been developed. It is widely used for bonsai because of its flowers and for the unusual twisted bark the older specimens can attain. The term "balaustine" (Latin: balaustinus) is also used for a pomegranate-red color.
The ancient city of Granada in Spain was renamed after the fruit during the Moorish period and today the province of Granada uses pomegranate as a charge in heraldry for its canting arms.
Spanish colonists later introduced the fruit to the Caribbean and America (Spanish America), but in the English colonies, it was less at home: "Don't use the pomegranate inhospitably, a stranger that has come so far to pay his respects to thee," the English Quaker Peter Collinson wrote to the botanizing John Bartram in Philadelphia, 1762. "Plant it against the side of thy house, nail it close to the wall. In this manner it thrives wonderfully with us, and flowers beautifully, and bears fruit this hot year. I have twenty-four on one tree... Doctor Fothergill says, of all trees this is most salutiferous to mankind."
The pomegranate had been introduced as an exotic to England the previous century, by John Tradescant the elder, but the disappointment that it did not set fruit there led to its repeated introduction to the American colonies, even New England. It succeeded in the South: Bartram received a barrel of pomegranates and oranges from a correspondent in Charleston, South Carolina, 1764. John Bartram partook of "delitious" pomegranates with Noble Jones at Wormsloe Plantation, near Savannah, Georgia, in September 1765. Thomas Jefferson planted pomegranates at Monticello in 1771: he had them from George Wythe of Williamsburg.
CULINARY USE
After the pomegranate is opened by scoring it with a knife and breaking it open, the seeds are separated from the peel and internal white pulp membranes. Separating the seeds is easier in a bowl of water because the seeds sink and the inedible pulp floats. Freezing the entire fruit also makes it easier to separate. Another effective way of quickly harvesting the seeds is to cut the pomegranate in half, score each half of the exterior rind four to six times, hold the pomegranate half over a bowl, and smack the rind with a large spoon. The seeds should eject from the pomegranate directly into the bowl, leaving only a dozen or more deeply embedded seeds to remove. The entire seed is consumed raw, though the watery, tasty sarcotesta is the desired part. The taste differs depending on the variety or cultivar of pomegranate and its ripeness.
Pomegranate juice can be sweet or sour, but most fruits are moderate in taste, with sour notes from the acidic tannins contained in the juice. Pomegranate juice has long been a popular drink in Europe, the Middle East and is now widely distributed in the United States and Canada.
Grenadine syrup long ago consisted of thickened and sweetened pomegranate juice, now is usually a sales name for a syrup based on various berries, citric acid, and food coloring, mainly used in cocktail mixing. In Europe, Bols still manufactures grenadine syrup with pomegranate. Before tomatoes, a New World fruit, arrived in the Middle East, pomegranate juice, molasses, and vinegar were widely used in many Iranian foods, and are still found in traditional recipes such as fesenjān, a thick sauce made from pomegranate juice and ground walnuts, usually spooned over duck or other poultry and rice, and in ash-e anar (pomegranate soup).
Pomegranate seeds are used as a spice known as anardana (from Persian: anar + dana, pomegranate + seed), most notably in Indian and Pakistani cuisine. Dried whole seeds can often be obtained in ethnic Indian subcontinent markets. These seeds are separated from the flesh, dried for 10–15 days, and used as an acidic agent for chutney and curry preparation. Ground anardana is also used, which results in a deeper flavoring in dishes and prevents the seeds from getting stuck in teeth. Seeds of the wild pomegranate variety known as daru from the Himalayas are regarded as quality sources for this spice.
Dried pomegranate seeds, found in some natural specialty food markets, still contain some residual water, maintaining a natural sweet and tart flavor. Dried seeds can be used in several culinary applications, such as trail mix, granola bars, or as a topping for salad, yogurt, or ice cream.
In the Caucasus, pomegranate is used mainly for juice. In Azerbaijan, a sauce from pomegranate juice narsharab, (from Persian: (a)nar + sharab, lit. "pomegranate wine") is usually served with fish or tika kabab. In Turkey, pomegranate sauce (Turkish: nar ekşisi) is used as a salad dressing, to marinate meat, or simply to drink straight. Pomegranate seeds are also used in salads and sometimes as garnish for desserts such as güllaç. Pomegranate syrup or molasses is used in muhammara, a roasted red pepper, walnut, and garlic spread popular in Syria and Turkey.
In Greece, pomegranate (Greek: ρόδι, rodi) is used in many recipes, including kollivozoumi, a creamy broth made from boiled wheat, pomegranates, and raisins, legume salad with wheat and pomegranate, traditional Middle Eastern lamb kebabs with pomegranate glaze, pomegranate eggplant relish, and avocado-pomegranate dip. Pomegranate is also made into a liqueur, and as a popular fruit confectionery used as ice cream topping, mixed with yogurt, or spread as jam on toast. In Cyprus and Greece, and among the Greek Orthodox Diaspora, ρόδι (Greek for pomegranate) is used to make koliva, a mixture of wheat, pomegranate seeds, sugar, almonds, and other seeds served at memorial services.
In Mexico, they are commonly used to adorn the traditional dish chiles en nogada, representing the red of the Mexican flag in the dish which evokes the green (poblano pepper), white (nogada sauce) and red (pomegranate seeds) tricolor.
IN TRADITIONAL MEDICINE
In the Indian subcontinent's ancient Ayurveda system of traditional medicine, the pomegranate is frequently described as an ingredient in remedies.
In folk medicine pomegranate has been thought a contraceptive and abortifacient when the seeds or rind are eaten, or when as a vaginal suppository.
NUTRITION
A 100-g serving of pomegranate seeds provides 12% of the Daily Value (DV) for vitamin C, 16% DV for vitamin K and 10% DV for folate (table).
Pomegranate seeds are an excellent source of dietary fiber (20% DV) which is entirely contained in the edible seeds. People who choose to discard the seeds forfeit nutritional benefits conveyed by the seed fiber and micronutrients.
Pomegranate seed oil contains punicic acid (65.3%), palmitic acid (4.8%), stearic acid (2.3%), oleic acid (6.3%), and linoleic acid (6.6%).
RESEARCH
JUICE
The most abundant phytochemicals in pomegranate juice are polyphenols, including the hydrolyzable tannins called ellagitannins formed when ellagic acid and/or gallic acid binds with a carbohydrate to form pomegranate ellagitannins, also known as punicalagins.
The red color of juice can be attributed to anthocyanins, such as delphinidin, cyanidin, and pelargonidin glycosides. Generally, an increase in juice pigmentation occurs during fruit ripening.
The phenolic content of pomegranate juice is adversely affected by processing and pasteurization techniques.
PEEL
Compared to the pulp, the inedible pomegranate peel contains as much as three times the total amount of polyphenols, including condensed tannins, catechins, gallocatechins and prodelphinidins.
The higher phenolic content of the peel yields extracts for use in dietary supplements and food preservatives.
Health claims
Despite limited research data, manufacturers and marketers of pomegranate juice have liberally used evolving research results for product promotion. In February 2010, the FDA issued a Warning Letter to one such manufacturer, POM Wonderful, for using published literature to make illegal claims of unproven anti-disease benefits.
SYMBOLISM
ANCIENT EGYPT
Ancient Egyptians regarded the pomegranate as a symbol of prosperity and ambition. According to the Ebers Papyrus, one of the oldest medical writings from around 1500 BC, Egyptians used the pomegranate for treatment of tapeworm and other infections.
ANCIENT GREECE
The Greeks were familiar with the fruit far before it was introduced to Rome via Carthage. In Ancient Greek mythology, the pomegranate was known as the "fruit of the dead", and believed to have sprung from the blood of Adonis.
The myth of Persephone, the goddess of the underworld, prominently features the pomegranate. In one version of Greek mythology, Persephone was kidnapped by Hades and taken off to live in the underworld as his wife. Her mother, Demeter (goddess of the Harvest), went into mourning for her lost daughter, thus all green things ceased to grow. Zeus, the highest-ranking of the Greek gods, could not allow the Earth to die, so he commanded Hades to return Persephone. It was the rule of the Fates that anyone who consumed food or drink in the underworld was doomed to spend eternity there. Persephone had no food, but Hades tricked her into eating six pomegranate seeds while she was still his prisoner, so she was condemned to spend six months in the underworld every year. During these six months, while Persephone sits on the throne of the underworld beside her husband Hades, her mother Demeter mourns and no longer gives fertility to the earth. This was an ancient Greek explanation for the seasons. Dante Gabriel Rossetti's painting Persephona depicts Persephone holding the fatal fruit. The number of seeds Persephone ate varies, depending on which version of the story is told. The number ranges from three to seven, which accounts for just one barren season if it is just three or four seeds, or two barren seasons (half the year) if she ate six or seven seeds.
The pomegranate also evoked the presence of the Aegean Triple Goddess who evolved into the Olympian Hera, who is sometimes represented offering the pomegranate, as in the Polykleitos' cult image of the Argive Heraion (see below). According to Carl A. P. Ruck and Danny Staples, the chambered pomegranate is also a surrogate for the poppy's narcotic capsule, with its comparable shape and chambered interior. On a Mycenaean seal illustrated in Joseph Campbell's Occidental Mythology 1964, figure 19, the seated Goddess of the double-headed axe (the labrys) offers three poppy pods in her right hand and supports her breast with her left. She embodies both aspects of the dual goddess, life-giving and death-dealing at once. The Titan Orion was represented as "marrying" Side, a name that in Boeotia means "pomegranate", thus consecrating the primal hunter to the Goddess. Other Greek dialects call the pomegranate rhoa; its possible connection with the name of the earth goddess Rhea, inexplicable in Greek, proved suggestive for the mythographer Karl Kerenyi, who suggested the consonance might ultimately derive from a deeper, pre-Indo-European language layer.
In the 5th century BC, Polycleitus took ivory and gold to sculpt the seated Argive Hera in her temple. She held a scepter in one hand and offered a pomegranate, like a 'royal orb', in the other. "About the pomegranate I must say nothing," whispered the traveller Pausanias in the 2nd century, "for its story is somewhat of a holy mystery." In the Orion story, Hera cast pomegranate-Side (an ancient city in Antalya) into dim Erebus — "for daring to rival Hera's beauty", which forms the probable point of connection with the older Osiris/Isis story.[citation needed] Since the ancient Egyptians identified the Orion constellation in the sky as Sah the "soul of Osiris", the identification of this section of the myth seems relatively complete. Hera wears, not a wreath nor a tiara nor a diadem, but clearly the calyx of the pomegranate that has become her serrated crown.[citation needed] The pomegranate has a calyx shaped like a crown. In Jewish tradition, it has been seen as the original "design" for the proper crown. In some artistic depictions, the pomegranate is found in the hand of Mary, mother of Jesus.
A pomegranate is displayed on coins from the ancient city of Side, Pamphylia.
Within the Heraion at the mouth of the Sele, near Paestum, Magna Graecia, is a chapel devoted to the Madonna del Granato, "Our Lady of the Pomegranate", "who by virtue of her epithet and the attribute of a pomegranate must be the Christian successor of the ancient Greek goddess Hera", observes the excavator of the Heraion of Samos, Helmut Kyrieleis.
In modern times, the pomegranate still holds strong symbolic meanings for the Greeks. On important days in the Greek Orthodox calendar, such as the Presentation of the Virgin Mary and on Christmas Day, it is traditional to have at the dinner table polysporia, also known by their ancient name panspermia, in some regions of Greece. In ancient times, they were offered to Demeter[citation needed] and to the other gods for fertile land, for the spirits of the dead and in honor of compassionate Dionysus.[citation needed] When one buys a new home, it is conventional for a house guest to bring as a first gift a pomegranate, which is placed under/near the ikonostasi (home altar) of the house, as a symbol of abundance, fertility, and good luck. Pomegranates are also prominent at Greek weddings and funerals.[citation needed] When Greeks commemorate their dead, they make kollyva as offerings, which consist of boiled wheat, mixed with sugar and decorated with pomegranate. It is also traditional in Greece to break a pomegranate on the ground at weddings and on New Years. Pomegranate decorations for the home are very common in Greece and sold in most home goods stores.
ANCIENT ISRAEL AND JUDAISM
Pomegranates were known in Ancient Israel as the fruits which the scouts brought to Moses to demonstrate the fertility of the "promised land". The Book of Exodus describes the me'il ("robe of the ephod") worn by the Hebrew high priest as having pomegranates embroidered on the hem alternating with golden bells which could be heard as the high priest entered and left the Holy of Holies. According to the Books of Kings, the capitals of the two pillars (Jachin and Boaz) that stood in front of Solomon's Temple in Jerusalem were engraved with pomegranates. Solomon is said to have designed his coronet based on the pomegranate's "crown" (calyx).
It is traditional to consume pomegranates on Rosh Hashana because, with its numerous seeds, it symbolizes fruitfulness. Also, it is said to have 613 seeds, which corresponds with the 613 mitzvot or commandments of the Torah.[61] This particular tradition is referred to in the opening pages of Ursula Dubosarsky's novel Theodora's Gift.
The pomegranate appeared on the ancient coins of Judea. When not in use, the handles of Torah scrolls are sometimes covered with decorative silver globes similar in shape to "pomegranates" (rimmonim). Some Jewish scholars believe the pomegranate was the forbidden fruit in the Garden of Eden.[60] Pomegranates are one of the Seven Species (Hebrew: שבעת המינים, Shiv'at Ha-Minim) of fruits and grains enumerated in the Hebrew Bible (Deuteronomy 8:8) as being special products of the Land of Israel. The pomegranate is mentioned in the Bible many times, including this quote from the Songs of Solomon, "Thy lips are like a thread of scarlet, and thy speech is comely: thy temples are like a piece of a pomegranate within thy locks." (Song of Solomon 4:3). Pomegranates also symbolize the mystical experience in the Jewish mystical tradition, or kabbalah, with the typical reference being to entering the "garden of pomegranates" or pardes rimonim; this is also the title of a book by the 16th-century mystic Moses ben Jacob Cordovero.
IN EUROPEAN CHRISTIAN MOTIFS
In the earliest incontrovertible appearance of Christ in a mosaic, a 4th-century floor mosaic from Hinton St Mary, Dorset, now in the British Museum, the bust of Christ and the chi rho are flanked by pomegranates. Pomegranates continue to be a motif often found in Christian religious decoration. They are often woven into the fabric of vestments and liturgical hangings or wrought in metalwork. Pomegranates figure in many religious paintings by the likes of Sandro Botticelli and Leonardo da Vinci, often in the hands of the Virgin Mary or the infant Jesus. The fruit, broken or bursting open, is a symbol of the fullness of Jesus' suffering and resurrection.
In the Eastern Orthodox Church, pomegranate seeds may be used in kolyva, a dish prepared for memorial services, as a symbol of the sweetness of the heavenly kingdom.
IN THE QUR´AN
According to the Qur'an, pomegranates grow in the gardens of paradise (55:68). The Qur'an also mentions pomegranates three times.(6:99, 6:141, 55:68)
AFGHANISTAN
Pomegranate, a favorite fall and winter fruit in Afghanistan, has mainly two varieties: one that is sweet and dark red with hard seeds growing in and around Kandhar province, and the other that has soft seeds with variable color growing in the central/northern region. The largest market for Afghan pomegranates is India followed by Pakistan, Russia, United Arab Emirates and Europe.
ARMENIA
The pomegranate is one of the main fruits in Armenian culture (the others being apricot and grapes). Its juice is famous with Armenians in food and heritage. The pomegranate is the symbol of Armenia and represents fertility, abundance and marriage. For example, the fruit played an integral role in a wedding custom widely practiced in ancient Armenia: a bride was given a pomegranate fruit, which she threw against a wall, breaking it into pieces. Scattered pomegranate seeds ensured the bride future children. In Karabakh, it was customary to put fruits next to the bridal couple during the first night of marriage, among them the pomegranate, which was said to ensure happiness. It is likely that newlyweds also enjoyed pomegranate wine. The symbolism of the pomegranate is that it protected a woman from infertility and protected a man's virility. Both homemade and commercial wine is made from pomegranate in Armenia. The Color of Pomegranates (1969) is a movie directed by Sergei Parajanov. It is a biography of the Armenian ashug Sayat-Nova (King of Song) which attempts to reveal the poet's life visually and poetically rather than literally.
AZERBAIJAN
Pomegranate is considered one of the symbols of Azerbaijan. Annually in October, a cultural festival is held in Goychay, Azerbaijan known as the Goychay Pomegranate Festival. The festival features Azerbaijani fruit-cuisine mainly the pomegranates from Goychay, which is famous for its pomegranate growing industry. At the festival, a parade is held with traditional Azerbaijani dances and Azerbaijani music. Pomegranate was depicted on the official logo of the 2015 European Games held in Azerbaijan. Nar the Pomegranate was one of the two mascots of these games. Pomegranates also featured on the jackets worn by Azerbaijani male athletes at the games' opening ceremony.
IRAN AND ANCIENT PERSIA
Pomegranate was the symbol of fertility in ancient Persian culture.[citation needed] In Persian mythology, Isfandiyar eats a pomegranate and becomes invincible. In the Greco-Persian Wars, Herodotus mentions golden pomegranates adorning the spears of warriors in the phalanx. Even in today's Iran, pomegranate may imply love and fertility.
Iran produces pomegranates as a common crop.[citation needed] Its juice and paste have a role in some Iranian cuisines, e.g. chicken, ghormas and refreshment bars. Pomegranate skins may be used to stain wool and silk in the carpet industry.
Pomegranate Festival is an annual cultural and artistic festival held during October in Tehran[citation needed] to exhibit and sell pomegranates, food products and handicrafts.
PAKISTAN
The pomegranate (known as "anār" in Urdu) is a popular fruit in Pakistan. It is grown in Pakistan and is also imported from Afghanistan.
INDIA
In some Hindu traditions, the pomegranate (Hindi: anār) symbolizes prosperity and fertility, and is associated with both Bhoomidevi (the earth goddess) and Lord Ganesha (the one fond of the many-seeded fruit). The Tamil name maadulampazham is a metaphor for a woman's mind. It is derived from, maadhu=woman, ullam=mind, which means as the seeds are hidden, it is not easy to decipher a woman's mind.
CHINA
Introduced to China during the Tang Dynasty (618-907 AD), the pomegranate (Chinese: 石榴; pinyin: shíliu) in olden times was considered an emblem of fertility and numerous progeny. This symbolism is a pun on the Chinese character 子 (zǐ) which, as well as meaning seed, also means "offspring" thus a fruit containing so many seeds is a sign of fecundity. Pictures of the ripe fruit with the seeds bursting forth were often hung in homes to bestow fertility and bless the dwelling with numerous offspring, an important facet of traditional Chinese culture.

Really pleased to find another one of these Globular Springtails. These guys are potentially easy to overlook as initially they resemble some of the Dicyrtomina sp, but on comparing the ocelli(eyes) there is an immediate difference, with Calvatomina nr superba there is a difference in pigmentation, see comments.
Only found this one individual on a fence in woodland, I was actually looking for Katiannidae, but found this instead :o) This is possibly an introduced species, as it closely resembles a species found in New Zealand.

"Region: America
Class: Mammalia
Order: Carnivora
Family: Ursidae
Genus: Ursus
Scientific Name: Ursus maritimus
Description : Polar bears are considered the largest land carnivores in the world, matched only by very large individual Kodiak brown bears. Both sexes differ in size throughout their range; males being much larger than females and continuing to grow for a longer period of time. These bears have long, massive skulls, necks and bodies with long legs and large paws. Ears and tail are short. The nose is more prominent or “Roman” with a black rhinarium (nose pad). The tongue is black and the eyes brown. The surface of the skin is also black. Fur colour varies slightly with the season: new coats grown just prior to the winter season are very white appearing as slightly creamy white against the stark white of their icy winter environment. This pelage is thick, coarse and long with dense underfur. Guard hairs, found throughout the pelage, are shiny, almost glossy, oily and waterproof and have hollow shafts. Polar bears moult annually between the end of May and August. The coat becomes thinner and has a yellow wash or is almost a golden colour. Male polar bears weigh between 400 – 600 kg, and have been recorded up to a maximum of 800 kg. Females are smaller than the males weighing up to 300 kg, and when pregnant up to 460 kg. Polar bears are 2.5 – 3.5 m long.
Distribution : The polar bear is circumpolar in distribution, inhabiting all Arctic seas and coastlines. It is found on the pack-ice off the Alaskan coast north of Bering Strait, off the coasts of Greenland and along the Eurasian Arctic coast from Spitsbergen to Wrangell Island. Rare stragglers reach Iceland. Individual bears have been seen on the frozen Arctic Ocean as far as latitude 88 degrees North, only 2 degrees from the North Pole. In Canada, they are found along the Arctic coasts from Alaska to Labrador and from the tip of James Bay to northern Ellesmere Island. Polar bears do roam as far as 150 kilometres inland into the coniferous forests, where they live very differently from the polar bears which belong to the high Arctic.
Habitat : They prefer areas of annual ice, which they use as a hunting platform and protective cover. This includes snow-drifted pressure ridges, refrozen cracks and areas of open water surrounded by ice. In areas where the pack ice melts by mid to late summer they come inland and live in coniferous forest areas. Here they remain until the ice re-freezes. Areas of solidly frozen sea ice and the open seas are avoided. Generally they are most common along coastal areas. Some do enter the permanent pack ice.
Food : The ringed seal is by far the most common prey. They also eat bearded seal, harp seal and hooded seal. Young walrus are sometimes taken. During the summer months they feed upon the shoreline carrion, fish, mussels, crabs, starfish, lemmings and the eggs and nestling young of waterfowl and cliff-dwelling birds. They will also graze on kelp, grasses and eat mushrooms and crowberries.
Reproduction and Development : Normally they are solitary animals outside the breeding season, the exception being a mother with cubs. Polar bears mate in mid-summer. Females first start to breed at 3 to 5 years of age. In April and May adult females are in oestrus and ready to accept a mate. They are polyandrous, meaning one female will mate with more than one male in one breeding season. Males fight among themselves for the female’s attention and a couple will pair off for a period of a few days to two weeks. With females, delayed implantation occurs, the fertilized egg does not implant in the uterus until mid-September to mid-October. Embryonic development begins at this time. Gestation periods, therefore, vary a great deal when including this period of delay. Females choose suitable locations to build their maternity dens in mid-October and retreat to them for the winter season. They give birth to one to four cubs somewhere between late November and early January. Twins are most common. The newborns are small; 25 to 30 cm long and weigh less than 1 kg. They are covered with very fine hair, appearing almost naked and their eyes are closed. Their eyes open at 6 weeks. Growth is very quick; at two months their fur has thickened; they weigh about 5 kg and move about the den. By mid-March to early April, when the den is opened, the cubs weigh about 10 kg and are surprisingly strong. The cubs suckle for nine months, occasionally one year. They are very dependent on their mother and stay with her for two years. At that time they weigh 90 - 180 kg and are half grown.
Adaptations : Polar bears are wonderfully adapted to their Arctic surroundings.
Locomotion. On land a shuffling walk may be increased to a rolling gallop of 40 km/h and can outrun caribou over a short distance. Bears are often seen standing high on their hind legs, necks stretched to scan the landscape. On thin ice, legs are spread to distribute body mass. Thickly padded and furred soles allow the bear to move quietly as well as providing good traction. Small bumps and cavities on the soles act like suction cups keeping bears from slipping on the ice. The claws are used to dig into icy slopes and to grip prey. They are strong swimmers, paddling with their forefeet only and trailing their hind feet which act as a rudder. They can stay submerged for over one minute, keeping their eyes open. They swim at a speed of approximately 6.4 km/h, often covering long distances.
Insulation. Polar bears have a thick layer of sub-cutaneous fat and very dense underfur with several layers of glossy guard hair on the outside. Their pelt is much thicker in winter and provides excellent insulation. The fat layer also adds to buoyancy in the water. Water is shed easily from the oily waterproof fur. Small, furry ears have a heavy network of blood vessels, keeping them warm and conserving heat. The tail is short and rounded also conserving heat. Fur is very dense around the soles of the feet.
Pelage. The creamy white appearance of the coat allows the bear to be inconspicuous when hunting seal. Each hair is similar to an optical fibre; colourless and hollow. Being translucent, it reflects the heat from the sun down to the base of the hair, where it is absorbed by the black skin. Whiteness comes from reflection of light rather than pigmentation.
Hunting. Bears use their keen sense of smell to detect seal breathing holes. These can be up to a kilometer away and covered by a layer of snow and ice. They will stand or lie by the seal’s blowhole in the ice for hours; they may swim towards seals resting on the ice flows with only their nose showing above the water. They will dive quietly, then swim up to the ice edge and jump out on the seal, and will also crawl towards a sunbathing seal using every piece of raised ice to conceal the approach.
Denning. Both sexes occupy dens for shelter. Topographic factors influence the den sites. In Canadian core areas, dens frequently occur on south-facing slopes where northerly prevailing winds create the best drifts, where the wind-chill is least and insulation from received solar radiation is greatest. One of the three largest denning areas worldwide is in Canada. There are three main types of winter refuges: maternity dens, temporary dens and winter shelters. During the winter any bear may dig a temporary den and use it for a few days during a storm, or take shelter in a natural cavity. Winter shelters are used for longer periods of time as resting places. This type of shelter is usually roomier with additional features such as alcoves, porches and ventilation holes. Bears do not hibernate in the strict sense of the word; they have the ability to slow down their metabolism to conserve energy at any time of year. The state of self-induced lethargy while in the shelter allows them to preserve their vital fat reserves. During this time, the body temperature of the polar bear decreases by a few degrees from normal and the respiration rates are markedly reduced. Maternity dens are built and occupied by pregnant females and can vary in size. The denning chamber is at the upper end of an entrance tunnel 1 to 2 m long. It averages 1.5 m in diameter with a height of 90 to 100cm in the middle. Drifting snow seals the entrance. The chamber is higher than the tunnel, trapping bear body heat inside. Dens not only provide a safe place to give birth to her cubs, but are also a place of protection for the cubs during their first few months. During this time she does not leave the den, remaining with her cubs and living on her reserves of fat. In the spring, with her fat severely depleted she must leave to find food to sustain herself and her cubs. After they leave the maternity den she will build temporary refuges in which to nurse, rest and shelter her young cubs and warms them as they all sleep together. She heads with her cubs towards the nearest supply of food, this is usually pack ice.
Sight and sounds. Polar bears have good eyesight. Their eyes have inner eyelids that keep the glare of the sun on snow and ice from blinding them. When defending a food source from other bears they use a deep growl. They hiss and snort to show aggression. Angry bears use loud roars and growls. Mothers scold cubs with a low growl.
Threats to Survival : Polar bears are one of the animals most threatened by global warming. They depend entirely on sea ice as a platform from which to hunt seals. Reduction of the total ice cover in the Arctic is a serious concern globally. When the ice does not form or forms too late in the season many polar bears starve. In Hudson Bay, scientists have found the main cause of death for cubs to be either lack of food or lack of fat on nursing mothers. Exploitation of minerals and fossil fuels in the Arctic pose a continuous threat. Of the oil and natural gas deposits globally, 20% are located in the Arctic. As the ice cap recedes these become more accessible. Countries are competing which each other in claiming ownership of Arctic and its resources. This can only result in further and more drastic impact on polar bear habitat.

The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. In many contexts, potato refers to the edible tuber, but it can also refer to the plant itself. Common or slang terms include tater, tattie and spud. Potatoes were introduced to Europe in the second half of the 16th century by the Spanish. Today they are a staple food in many parts of the world and an integral part of much of the world's food supply. As of 2014, potatoes were the world's fourth-largest food crop after maize (corn), wheat, and rice.
Wild potato species can be found throughout the Americas, from the United States to southern Chile. The potato was originally believed to have been domesticated independently in multiple locations, but later genetic testing of the wide variety of cultivars and wild species traced a single origin for potatoes. In the area of present-day southern Peru and extreme northwestern Bolivia, from a species in the Solanum brevicaule complex, potatoes were domesticated approximately 7,000–10,000 years ago. In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated.
Following millennia of selective breeding, there are now over 1,000 different types of potatoes. Over 99% of presently cultivated potatoes worldwide descended from varieties that originated in the lowlands of south-central Chile, which have displaced formerly popular varieties from the Andes.
The importance of the potato as a food source and culinary ingredient varies by region and is still changing. It remains an essential crop in Europe, especially eastern and central Europe, where per capita production is still the highest in the world, while the most rapid expansion in production over the past few decades has occurred in southern and eastern Asia, with China and India leading the world in overall production as of 2014.
Being a nightshade similar to tomatoes, the vegetative and fruiting parts of the potato contain the toxin solanine and are not fit for human consumption. Normal potato tubers that have been grown and stored properly produce glycoalkaloids in amounts small enough to be negligible to human health, but if green sections of the plant (namely sprouts and skins) are exposed to light, the tuber can accumulate a high enough concentration of glycoalkaloids to affect human health.
ETYMOLOGY
The English word potato comes from Spanish patata (the name used in Spain). The Spanish Royal Academy says the Spanish word is a hybrid of the Taíno batata (sweet potato) and the Quechua papa (potato). The name originally referred to the sweet potato although the two plants are not closely related. The 16th-century English herbalist John Gerard referred to sweet potatoes as "common potatoes", and used the terms "bastard potatoes" and "Virginia potatoes" for the species we now call "potato". In many of the chronicles detailing agriculture and plants, no distinction is made between the two. Potatoes are occasionally referred to as "Irish potatoes" or "white potatoes" in the United States, to distinguish them from sweet potatoes.
The name spud for a small potato comes from the digging of soil (or a hole) prior to the planting of potatoes. The word has an unknown origin and was originally (c. 1440) used as a term for a short knife or dagger, probably related to the Latin "spad-" a word root meaning "sword"; cf. Spanish "espada", English "spade" and "spadroon". It subsequently transferred over to a variety of digging tools. Around 1845, the name transferred to the tuber itself, the first record of this usage being in New Zealand English. The origin of the word "spud" has erroneously been attributed to an 18th-century activist group dedicated to keeping the potato out of Britain, calling itself The Society for the Prevention of Unwholesome Diet (S.P.U.D.). It was Mario Pei's 1949 The Story of Language that can be blamed for the word's false origin. Pei writes, "the potato, for its part, was in disrepute some centuries ago. Some Englishmen who did not fancy potatoes formed a Society for the Prevention of Unwholesome Diet. The initials of the main words in this title gave rise to spud." Like most other pre-20th century acronymic origins, this is false, and there is no evidence that a Society for the Prevention of Unwholesome Diet ever existed.
CHARACTERISTICS
Potato plants are herbaceous perennials that grow about 60 cm high, depending on variety, with the leaves dying back after flowering, fruiting and tuber formation. They bear white, pink, red, blue, or purple flowers with yellow stamens. In general, the tubers of varieties with white flowers have white skins, while those of varieties with colored flowers tend to have pinkish skins. Potatoes are mostly cross-pollinated by insects such as bumblebees, which carry pollen from other potato plants, though a substantial amount of self-fertilizing occurs as well. Tubers form in response to decreasing day length, although this tendency has been minimized in commercial varieties.
After flowering, potato plants produce small green fruits that resemble green cherry tomatoes, each containing about 300 seeds. Like all parts of the plant except the tubers, the fruit contain the toxic alkaloid solanine and are therefore unsuitable for consumption. All new potato varieties are grown from seeds, also called "true potato seed", "TPS" or "botanical seed" to distinguish it from seed tubers. New varieties grown from seed can be propagated vegetatively by planting tubers, pieces of tubers cut to include at least one or two eyes, or cuttings, a practice used in greenhouses for the production of healthy seed tubers. Plants propagated from tubers are clones of the parent, whereas those propagated from seed produce a range of different varieties.
GENETICS
There are about 5,000 potato varieties worldwide. Three thousand of them are found in the Andes alone, mainly in Peru, Bolivia, Ecuador, Chile, and Colombia. They belong to eight or nine species, depending on the taxonomic school. Apart from the 5,000 cultivated varieties, there are about 200 wild species and subspecies, many of which can be cross-bred with cultivated varieties. Cross-breeding has been done repeatedly to transfer resistances to certain pests and diseases from the gene pool of wild species to the gene pool of cultivated potato species. Genetically modified varieties have met public resistance in the United States and in the European UnionThe major species grown worldwide is Solanum tuberosum (a tetraploid with 48 chromosomes), and modern varieties of this species are the most widely cultivated. There are also four diploid species (with 24 chromosomes): S. stenotomum, S. phureja, S. goniocalyx, and S. ajanhuiri. There are two triploid species (with 36 chromosomes): S. chaucha and S. juzepczukii. There is one pentaploid cultivated species (with 60 chromosomes): S. curtilobum. There are two major subspecies of Solanum tuberosum: andigena, or Andean; and tuberosum, or Chilean. The Andean potato is adapted to the short-day conditions prevalent in the mountainous equatorial and tropical regions where it originated; the Chilean potato, however, native to the Chiloé Archipelago, is adapted to the long-day conditions prevalent in the higher latitude region of southern Chile.
The International Potato Center, based in Lima, Peru, holds an ISO-accredited collection of potato germplasm. The international Potato Genome Sequencing Consortium announced in 2009 that they had achieved a draft sequence of the potato genome. The potato genome contains 12 chromosomes and 860 million base pairs, making it a medium-sized plant genome. More than 99 percent of all current varieties of potatoes currently grown are direct descendants of a subspecies that once grew in the lowlands of south-central Chile. Nonetheless, genetic testing of the wide variety of cultivars and wild species affirms that all potato subspecies derive from a single origin in the area of present-day southern Peru and extreme Northwestern Bolivia (from a species in the Solanum brevicaule complex). The wild Crop Wild Relatives Prebreeding project encourages the use of wild relatives in breeding programs. Enriching and preserving the gene bank collection to make potatoes adaptive to diverse environmental conditions is seen as a pressing issue due to climate change.
Most modern potatoes grown in North America arrived through European settlement and not independently from the South American sources, although at least one wild potato species, Solanum fendleri, naturally ranges from Peru into Texas, where it is used in breeding for resistance to a nematode species that attacks cultivated potatoes. A secondary center of genetic variability of the potato is Mexico, where important wild species that have been used extensively in modern breeding are found, such as the hexaploid Solanum demissum, as a source of resistance to the devastating late blight disease. Another relative native to this region, Solanum bulbocastanum, has been used to genetically engineer the potato to resist potato blight.
Potatoes yield abundantly with little effort, and adapt readily to diverse climates as long as the climate is cool and moist enough for the plants to gather sufficient water from the soil to form the starchy tubers. Potatoes do not keep very well in storage and are vulnerable to moulds that feed on the stored tubers and quickly turn them rotten, whereas crops such as grain can be stored for several years with a low risk of rot. The yield of Calories per acre (about 9.2 million) is higher than that of maize (7.5 million), rice (7.4 million), wheat (3 million), or soybean (2.8 million).
VARIETIES
There are close to 4,000 varieties of potato including common commercial varieties, each of which has specific agricultural or culinary attributes. Around 80 varieties are commercially available in the UK. In general, varieties are categorized into a few main groups based on common characteristics, such as russet potatoes (rough brown skin), red potatoes, white potatoes, yellow potatoes (also called Yukon potatoes) and purple potatoes.
For culinary purposes, varieties are often differentiated by their waxiness: floury or mealy baking potatoes have more starch (20–22%) than waxy boiling potatoes (16–18%). The distinction may also arise from variation in the comparative ratio of two different potato starch compounds: amylose and amylopectin. Amylose, a long-chain molecule, diffuses from the starch granule when cooked in water, and lends itself to dishes where the potato is mashed. Varieties that contain a slightly higher amylopectin content, which is a highly branched molecule, help the potato retain its shape after being boiled in water. Potatoes that are good for making potato chips or potato crisps are sometimes called "chipping potatoes", which means they meet the basic requirements of similar varietal characteristics, being firm, fairly clean, and fairly well-shaped.
The European Cultivated Potato Database (ECPD) is an online collaborative database of potato variety descriptions that is updated and maintained by the Scottish Agricultural Science Agency within the framework of the European Cooperative Programme for Crop Genetic Resources Networks (ECP/GR)—which is run by the International Plant Genetic Resources Institute (IPGRI).
PIGMENTATION
Dozens of potato cultivars have been selectively bred specifically for their skin or, more commonly, flesh color, including gold, red, and blue varieties that contain varying amounts of phytochemicals, including carotenoids for gold/yellow or polyphenols for red or blue cultivars. Carotenoid compounds include provitamin A alpha-carotene and beta-carotene, which are converted to the essential nutrient, vitamin A, during digestion. Anthocyanins mainly responsible for red or blue pigmentation in potato cultivars do not have nutritional significance, but are used for visual variety and consumer appeal. Recently, as of 2010, potatoes have also been bioengineered specifically for these pigmentation traits.
GENETICALLY ENGINEERED POTATOES
Genetic research has produced several genetically modified varieties. 'New Leaf', owned by Monsanto Company, incorporates genes from Bacillus thuringiensis, which confers resistance to the Colorado potato beetle; 'New Leaf Plus' and 'New Leaf Y', approved by US regulatory agencies during the 1990s, also include resistance to viruses. McDonald's, Burger King, Frito-Lay, and Procter & Gamble announced they would not use genetically modified potatoes, and Monsanto published its intent to discontinue the line in March 2001.
Waxy potato varieties produce two main kinds of potato starch, amylose and amylopectin, the latter of which is most industrially useful. BASF developed the Amflora potato, which was modified to express antisense RNA to inactivate the gene for granule bound starch synthase, an enzyme which catalyzes the formation of amylose. Amflora potatoes therefore produce starch consisting almost entirely of amylopectin, and are thus more useful for the starch industry. In 2010, the European Commission cleared the way for 'Amflora' to be grown in the European Union for industrial purposes only—not for food. Nevertheless, under EU rules, individual countries have the right to decide whether they will allow this potato to be grown on their territory. Commercial planting of 'Amflora' was expected in the Czech Republic and Germany in the spring of 2010, and Sweden and the Netherlands in subsequent years. Another GM potato variety developed by BASF is 'Fortuna' which was made resistant to late blight by adding two resistance genes, blb1 and blb2, which originate from the Mexican wild potato Solanum bulbocastanum. In October 2011 BASF requested cultivation and marketing approval as a feed and food from the EFSA. In 2012, GMO development in Europe was stopped by BASF.
In November 2014, the USDA approved a genetically modified potato developed by J.R. Simplot Company, which contains genetic modifications that prevent bruising and produce less acrylamide when fried than conventional potatoes; the modifications do not cause new proteins to be made, but rather prevent proteins from being made via RNA interference.
HISTORY
The potato was first domesticated in the region of modern-day southern Peru and extreme northwestern Bolivia between 8000 and 5000 BC. It has since spread around the world and become a staple crop in many countries.
The earliest archaeologically verified potato tuber remains have been found at the coastal site of Ancon (central Peru), dating to 2500 BC. The most widely cultivated variety, Solanum tuberosum tuberosum, is indigenous to the Chiloé Archipelago, and has been cultivated by the local indigenous people since before the Spanish conquest.
According to conservative estimates, the introduction of the potato was responsible for a quarter of the growth in Old World population and urbanization between 1700 and 1900. In the Altiplano, potatoes provided the principal energy source for the Inca civilization, its predecessors, and its Spanish successor. Following the Spanish conquest of the Inca Empire, the Spanish introduced the potato to Europe in the second half of the 16th century, part of the Columbian exchange. The staple was subsequently conveyed by European mariners to territories and ports throughout the world. The potato was slow to be adopted by European farmers, but soon enough it became an important food staple and field crop that played a major role in the European 19th century population boom. However, lack of genetic diversity, due to the very limited number of varieties initially introduced, left the crop vulnerable to disease. In 1845, a plant disease known as late blight, caused by the fungus-like oomycete Phytophthora infestans, spread rapidly through the poorer communities of western Ireland as well as parts of the Scottish Highlands, resulting in the crop failures that led to the Great Irish Famine. Thousands of varieties still persist in the Andes however, where over 100 cultivars might be found in a single valley, and a dozen or more might be maintained by a single agricultural household.
PRODUCTION
In 2016, world production of potatoes was 377 million tonnes, led by China with over 26% of the world total (see table). Other major producers were India, Russia, Ukraine and the United States. It remains an essential crop in Europe (especially eastern and central Europe), where per capita production is still the highest in the world, but the most rapid expansion over the past few decades has occurred in southern and eastern Asia.
NUTRITION
A raw potato is 79% water, 17% carbohydrates (88% is starch), 2% protein, and contains negligible fat (see table). In an amount measuring 100 grams, raw potato provides 322 kilojoules (77 kilocalories) of energy and is a rich source of vitamin B6 and vitamin C (23% and 24% of the Daily Value, respectively), with no other vitamins or minerals in significant amount (see table). The potato is rarely eaten raw because raw potato starch is poorly digested by humans. When a potato is baked, its contents of vitamin B6 and vitamin C decline notably, while there is little significant change in the amount of other nutrients.
Potatoes are often broadly classified as having a high glycemic index (GI) and so are often excluded from the diets of individuals trying to follow a low-GI diet. The GI of potatoes can vary considerably depending on the cultivar or cultivar category (such as "red", russet, "white", or King Edward), growing conditions and storage, preparation methods (by cooking method, whether it is eaten hot or cold, whether it is mashed or cubed or consumed whole), and accompanying foods consumed (especially the addition of various high-fat or high-protein toppings). In particular, consuming reheated or cooled potatoes that were previously cooked may yield a lower GI effect.
In the UK, potatoes are not considered by the National Health Service (NHS) as counting or contributing towards the recommended daily five portions of fruit and vegetables, the 5-A-Day program.
COMPARISON TO OTHER STAPLE FOODS
This table shows the nutrient content of potatoes next to other major staple foods, each one measured in its respective raw state, even though staple foods are not commonly eaten raw and are usually sprouted or cooked before eating. In sprouted and cooked form, the relative nutritional and anti-nutritional contents of each of these grains (or other foods) may be different from the values in this table. Each nutrient (every row) has the highest number highlighted to show the staple food with the greatest amount in a 100-gram raw portion.
TOXICITY
Potatoes contain toxic compounds known as glycoalkaloids, of which the most prevalent are solanine and chaconine. Solanine is found in other plants in the same family, Solanaceae, which includes such plants as deadly nightshade (Atropa belladonna), henbane (Hyoscyamus niger) and tobacco (Nicotiana spp.), as well as the food plants eggplant and tomato. These compounds, which protect the potato plant from its predators, are generally concentrated in its leaves, flowers, sprouts, and fruits (in contrast to the tubers). In a summary of several studies, the glycoalkaloid content was highest in the flowers and sprouts and lowest in the tuber flesh. (The glycoalkaloid content was, in order from highest to lowest: flowers, sprouts, leaves, skin, roots, berries, peel [skin plus outer cortex of tuber flesh], stems, and tuber flesh.)
Exposure to light, physical damage, and age increase glycoalkaloid content within the tuber. Cooking at high temperatures—over 170 °C—partly destroys these compounds. The concentration of glycoalkaloids in wild potatoes is sufficient to produce toxic effects in humans. Glycoalkaloid poisoning may cause headaches, diarrhea, cramps, and, in severe cases, coma and death. However, poisoning from cultivated potato varieties is very rare. Light exposure causes greening from chlorophyll synthesis, giving a visual clue as to which areas of the tuber may have become more toxic. However, this does not provide a definitive guide, as greening and glycoalkaloid accumulation can occur independently of each other.
Different potato varieties contain different levels of glycoalkaloids. The Lenape variety was released in 1967 but was withdrawn in 1970 as it contained high levels of glycoalkaloids. Since then, breeders developing new varieties test for this, and sometimes have to discard an otherwise promising cultivar. Breeders try to keep glycoalkaloid levels below 200 mg/kg). However, when these commercial varieties turn green, they can still approach solanine concentrations of 1000 mg/kg. In normal potatoes, analysis has shown solanine levels may be as little as 3.5% of the breeders' maximum, with 7–187 mg/kg being found. While a normal potato tuber has 12–20 mg/kg of glycoalkaloid content, a green potato tuber contains 250–280 mg/kg and its skin has 1500–2200 mg/kg.
GROWTH AND CULTIVATION
SEED POTATOES
Potatoes are generally grown from seed potatoes, tubers specifically grown to be free from disease and to provide consistent and healthy plants. To be disease free, the areas where seed potatoes are grown are selected with care. In the US, this restricts production of seed potatoes to only 15 states out of all 50 states where potatoes are grown. These locations are selected for their cold, hard winters that kill pests and summers with long sunshine hours for optimum growth. In the UK, most seed potatoes originate in Scotland, in areas where westerly winds prevent aphid attack and thus prevent spread of potato virus pathogens.
PHASES OF GROWTH
Potato growth is divided into five phases. During the first phase, sprouts emerge from the seed potatoes and root growth begins. During the second, photosynthesis begins as the plant develops leaves and branches. In the third phase, stolons develop from lower leaf axils on the stem and grow downwards into the ground and on these stolons new tubers develop as swellings of the stolon. This phase is often, but not always, associated with flowering. Tuber formation halts when soil temperatures reach 27 °C; hence potatoes are considered a cool-season, or winter, crop. Tuber bulking occurs during the fourth phase, when the plant begins investing the majority of its resources in its newly formed tubers. At this phase, several factors are critical to a good yield: optimal soil moisture and temperature, soil nutrient availability and balance, and resistance to pest attacks. The fifth and final phase is the maturation of the tubers: the plant canopy dies back, the tuber skins harden, and the sugars in the tubers convert to starches.
CHALLENGES
New tubers may start growing at the surface of the soil. Since exposure to light leads to an undesirable greening of the skins and the development of solanine as a protection from the sun's rays, growers cover surface tubers. Commercial growers cover them by piling additional soil around the base of the plant as it grows (called "hilling" up, or in British English "earthing up"). An alternative method, used by home gardeners and smaller-scale growers, involves covering the growing area with organic mulches such as straw or plastic sheets.
Correct potato husbandry can be an arduous task in some circumstances. Good ground preparation, harrowing, plowing, and rolling are always needed, along with a little grace from the weather and a good source of water. Three successive plowings, with associated harrowing and rolling, are desirable before planting. Eliminating all root-weeds is desirable in potato cultivation. In general, the potatoes themselves are grown from the eyes of another potato and not from seed. Home gardeners often plant a piece of potato with two or three eyes in a hill of mounded soil. Commercial growers plant potatoes as a row crop using seed tubers, young plants or microtubers and may mound the entire row. Seed potato crops are rogued in some countries to eliminate diseased plants or those of a different variety from the seed crop.
Potatoes are sensitive to heavy frosts, which damage them in the ground. Even cold weather makes potatoes more susceptible to bruising and possibly later rotting, which can quickly ruin a large stored crop.
PESTS
The historically significant Phytophthora infestans (late blight) remains an ongoing problem in Europe and the United States. Other potato diseases include Rhizoctonia, Sclerotinia, black leg, powdery mildew, powdery scab and leafroll virus.
Insects that commonly transmit potato diseases or damage the plants include the Colorado potato beetle, the potato tuber moth, the green peach aphid (Myzus persicae), the potato aphid, beet leafhoppers, thrips, and mites. The potato cyst nematode is a microscopic worm that thrives on the roots, thus causing the potato plants to wilt. Since its eggs can survive in the soil for several years, crop rotation is recommended.
During the crop year 2008, many of the certified organic potatoes produced in the United Kingdom and certified by the Soil Association as organic were sprayed with a copper pesticide to control potato blight (Phytophthora infestans). According to the Soil Association, the total copper that can be applied to organic land is 6 kg/ha/year.
According to an Environmental Working Group analysis of USDA and FDA pesticide residue tests performed from 2000 through 2008, 84% of the 2,216 tested potato samples contained detectable traces of at least one pesticide. A total of 36 unique pesticides were detected on potatoes over the 2,216 samples, though no individual sample contained more than 6 unique pesticide traces, and the average was 1.29 detectable unique pesticide traces per sample. The average quantity of all pesticide traces found in the 2,216 samples was 1.602 ppm. While this was a very low value of pesticide residue, it was the highest amongst the 50 vegetables analyzed.
HARVEST
At harvest time, gardeners usually dig up potatoes with a long-handled, three-prong "grape" (or graip), i.e., a spading fork, or a potato hook, which is similar to the graip but with tines at a 90° angle to the handle. In larger plots, the plow is the fastest implement for unearthing potatoes. Commercial harvesting is typically done with large potato harvesters, which scoop up the plant and surrounding earth. This is transported up an apron chain consisting of steel links several feet wide, which separates some of the dirt. The chain deposits into an area where further separation occurs. Different designs use different systems at this point. The most complex designs use vine choppers and shakers, along with a blower system to separate the potatoes from the plant. The result is then usually run past workers who continue to sort out plant material, stones, and rotten potatoes before the potatoes are continuously delivered to a wagon or truck. Further inspection and separation occurs when the potatoes are unloaded from the field vehicles and put into storage.
Immature potatoes may be sold as "creamer potatoes" and are particularly valued for taste. These are often harvested by the home gardener or farmer by "grabbling", i.e. pulling out the young tubers by hand while leaving the plant in place. A creamer potato is a variety of potato harvested before it matures to keep it small and tender. It is generally either a Yukon Gold potato or a red potato, called gold creamers or red creamers respectively, and measures approximately 2.5 cm in diameter. The skin of creamer potatoes is waxy and high in moisture content, and the flesh contains a lower level of starch than other potatoes. Like potatoes in general, they can be prepared by boiling, baking, frying, and roasting. Slightly older than creamer potatoes are "new potatoes", which are also prized for their taste and texture and often come from the same varieties.
Potatoes are usually cured after harvest to improve skin-set. Skin-set is the process by which the skin of the potato becomes resistant to skinning damage. Potato tubers may be susceptible to skinning at harvest and suffer skinning damage during harvest and handling operations. Curing allows the skin to fully set and any wounds to heal. Wound-healing prevents infection and water-loss from the tubers during storage. Curing is normally done at relatively warm temperatures 10 to 16 °C with high humidity and good gas-exchange if at all possible.
STORAGE
Storage facilities need to be carefully designed to keep the potatoes alive and slow the natural process of decomposition, which involves the breakdown of starch. It is crucial that the storage area is dark, ventilated well and, for long-term storage, maintained at temperatures near 4 °C. For short-term storage, temperatures of about 7 to 10 °C are preferred.
On the other hand, temperatures below 4 °C convert the starch in potatoes into sugar, which alters their taste and cooking qualities and leads to higher acrylamide levels in the cooked product, especially in deep-fried dishes. The discovery of acrylamides in starchy foods in 2002 has led to international health concerns. They are believed to be probable carcinogens and their occurrence in cooked foods is being studied for potentially influencing health problems.
Under optimum conditions in commercial warehouses, potatoes can be stored for up to 10–12 months. The commercial storage and retrieval of potatoes involves several phases: first drying surface moisture; wound healing at 85% to 95% relative humidity and temperatures below 25 °C; a staged cooling phase; a holding phase; and a reconditioning phase, during which the tubers are slowly warmed. Mechanical ventilation is used at various points during the process to prevent condensation and the accumulation of carbon dioxide.
When stored in homes unrefrigerated, the shelf life is usually a few weeks.
If potatoes develop green areas or start to sprout, trimming or peeling those green-colored parts is inadequate to remove copresent toxins, and such potatoes are no longer edible.
YIELD
The world dedicated 18.6 million ha in 2010 for potato cultivation. The average world farm yield for potato was 17.4 tonnes per hectare, in 2010. Potato farms in the United States were the most productive in 2010, with a nationwide average of 44.3 tonnes per hectare. United Kingdom was a close second.
New Zealand farmers have demonstrated some of the best commercial yields in the world, ranging between 60 and 80 tonnes per hectare, some reporting yields of 88 tonnes potatoes per hectare.
There is a big gap among various countries between high and low yields, even with the same variety of potato. Average potato yields in developed economies ranges between 38–44 tonnes per hectare. China and India accounted for over a third of world's production in 2010, and had yields of 14.7 and 19.9 tonnes per hectare respectively. The yield gap between farms in developing economies and developed economies represents an opportunity loss of over 400 million tonnes of potato, or an amount greater than 2010 world potato production. Potato crop yields are determined by factors such as the crop breed, seed age and quality, crop management practices and the plant environment. Improvements in one or more of these yield determinants, and a closure of the yield gap, can be a major boost to food supply and farmer incomes in the developing world.
USES
Potatoes are prepared in many ways: skin-on or peeled, whole or cut up, with seasonings or without. The only requirement involves cooking to swell the starch granules. Most potato dishes are served hot but some are first cooked, then served cold, notably potato salad and potato chips (crisps). Common dishes are: mashed potatoes, which are first boiled (usually peeled), and then mashed with milk or yogurt and butter; whole baked potatoes; boiled or steamed potatoes; French-fried potatoes or chips; cut into cubes and roasted; scalloped, diced, or sliced and fried (home fries); grated into small thin strips and fried (hash browns); grated and formed into dumplings, Rösti or potato pancakes. Unlike many foods, potatoes can also be easily cooked in a microwave oven and still retain nearly all of their nutritional value, provided they are covered in ventilated plastic wrap to prevent moisture from escaping; this method produces a meal very similar to a steamed potato, while retaining the appearance of a conventionally baked potato. Potato chunks also commonly appear as a stew ingredient. Potatoes are boiled between 10 and 25 minutes, depending on size and type, to become soft.
OTHER THAN FOR EATING
Potatoes are also used for purposes other than eating by humans, for example:
Potatoes are used to brew alcoholic beverages such as vodka, poitín, or akvavit.
They are also used as fodder for livestock. Livestock-grade potatoes, considered too small and/or blemished to sell or market for human use but suitable for fodder use, have been called chats in some dialects. They may be stored in bins until use; they are sometimes ensiled. Some farmers prefer to steam them rather than feed them raw and are equipped to do so efficiently.
Potato starch is used in the food industry as a thickener and binder for soups and sauces, in the textile industry as an adhesive, and for the manufacturing of papers and boards.
Maine companies are exploring the possibilities of using waste potatoes to obtain polylactic acid for use in plastic products; other research projects seek ways to use the starch as a base for biodegradable packaging.
Potato skins, along with honey, are a folk remedy for burns in India. Burn centres in India have experimented with the use of the thin outer skin layer to protect burns while healing.
Potatoes (mainly Russets) are commonly used in plant research. The consistent parenchyma tissue, the clonal nature of the plant and the low metabolic activity provide a very nice "model tissue" for experimentation. Wound-response studies are often done on potato tuber tissue, as are electron transport experiments. In this respect, potato tuber tissue is similar to Drosophila melanogaster, Caenorhabditis elegans and Escherichia coli: they are all "standard" research organisms.
Potatoes have been delivered with personalized messages as a novelty. Potato delivery services include Potato Parcel and Mail A Spud.

The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. In many contexts, potato refers to the edible tuber, but it can also refer to the plant itself. Common or slang terms include tater, tattie and spud. Potatoes were introduced to Europe in the second half of the 16th century by the Spanish. Today they are a staple food in many parts of the world and an integral part of much of the world's food supply. As of 2014, potatoes were the world's fourth-largest food crop after maize (corn), wheat, and rice.
Wild potato species can be found throughout the Americas, from the United States to southern Chile. The potato was originally believed to have been domesticated independently in multiple locations, but later genetic testing of the wide variety of cultivars and wild species traced a single origin for potatoes. In the area of present-day southern Peru and extreme northwestern Bolivia, from a species in the Solanum brevicaule complex, potatoes were domesticated approximately 7,000–10,000 years ago. In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated.
Following millennia of selective breeding, there are now over 1,000 different types of potatoes. Over 99% of presently cultivated potatoes worldwide descended from varieties that originated in the lowlands of south-central Chile, which have displaced formerly popular varieties from the Andes.
The importance of the potato as a food source and culinary ingredient varies by region and is still changing. It remains an essential crop in Europe, especially eastern and central Europe, where per capita production is still the highest in the world, while the most rapid expansion in production over the past few decades has occurred in southern and eastern Asia, with China and India leading the world in overall production as of 2014.
Being a nightshade similar to tomatoes, the vegetative and fruiting parts of the potato contain the toxin solanine and are not fit for human consumption. Normal potato tubers that have been grown and stored properly produce glycoalkaloids in amounts small enough to be negligible to human health, but if green sections of the plant (namely sprouts and skins) are exposed to light, the tuber can accumulate a high enough concentration of glycoalkaloids to affect human health.
ETYMOLOGY
The English word potato comes from Spanish patata (the name used in Spain). The Spanish Royal Academy says the Spanish word is a hybrid of the Taíno batata (sweet potato) and the Quechua papa (potato). The name originally referred to the sweet potato although the two plants are not closely related. The 16th-century English herbalist John Gerard referred to sweet potatoes as "common potatoes", and used the terms "bastard potatoes" and "Virginia potatoes" for the species we now call "potato". In many of the chronicles detailing agriculture and plants, no distinction is made between the two. Potatoes are occasionally referred to as "Irish potatoes" or "white potatoes" in the United States, to distinguish them from sweet potatoes.
The name spud for a small potato comes from the digging of soil (or a hole) prior to the planting of potatoes. The word has an unknown origin and was originally (c. 1440) used as a term for a short knife or dagger, probably related to the Latin "spad-" a word root meaning "sword"; cf. Spanish "espada", English "spade" and "spadroon". It subsequently transferred over to a variety of digging tools. Around 1845, the name transferred to the tuber itself, the first record of this usage being in New Zealand English. The origin of the word "spud" has erroneously been attributed to an 18th-century activist group dedicated to keeping the potato out of Britain, calling itself The Society for the Prevention of Unwholesome Diet (S.P.U.D.). It was Mario Pei's 1949 The Story of Language that can be blamed for the word's false origin. Pei writes, "the potato, for its part, was in disrepute some centuries ago. Some Englishmen who did not fancy potatoes formed a Society for the Prevention of Unwholesome Diet. The initials of the main words in this title gave rise to spud." Like most other pre-20th century acronymic origins, this is false, and there is no evidence that a Society for the Prevention of Unwholesome Diet ever existed.
CHARACTERISTICS
Potato plants are herbaceous perennials that grow about 60 cm high, depending on variety, with the leaves dying back after flowering, fruiting and tuber formation. They bear white, pink, red, blue, or purple flowers with yellow stamens. In general, the tubers of varieties with white flowers have white skins, while those of varieties with colored flowers tend to have pinkish skins. Potatoes are mostly cross-pollinated by insects such as bumblebees, which carry pollen from other potato plants, though a substantial amount of self-fertilizing occurs as well. Tubers form in response to decreasing day length, although this tendency has been minimized in commercial varieties.
After flowering, potato plants produce small green fruits that resemble green cherry tomatoes, each containing about 300 seeds. Like all parts of the plant except the tubers, the fruit contain the toxic alkaloid solanine and are therefore unsuitable for consumption. All new potato varieties are grown from seeds, also called "true potato seed", "TPS" or "botanical seed" to distinguish it from seed tubers. New varieties grown from seed can be propagated vegetatively by planting tubers, pieces of tubers cut to include at least one or two eyes, or cuttings, a practice used in greenhouses for the production of healthy seed tubers. Plants propagated from tubers are clones of the parent, whereas those propagated from seed produce a range of different varieties.
GENETICS
There are about 5,000 potato varieties worldwide. Three thousand of them are found in the Andes alone, mainly in Peru, Bolivia, Ecuador, Chile, and Colombia. They belong to eight or nine species, depending on the taxonomic school. Apart from the 5,000 cultivated varieties, there are about 200 wild species and subspecies, many of which can be cross-bred with cultivated varieties. Cross-breeding has been done repeatedly to transfer resistances to certain pests and diseases from the gene pool of wild species to the gene pool of cultivated potato species. Genetically modified varieties have met public resistance in the United States and in the European UnionThe major species grown worldwide is Solanum tuberosum (a tetraploid with 48 chromosomes), and modern varieties of this species are the most widely cultivated. There are also four diploid species (with 24 chromosomes): S. stenotomum, S. phureja, S. goniocalyx, and S. ajanhuiri. There are two triploid species (with 36 chromosomes): S. chaucha and S. juzepczukii. There is one pentaploid cultivated species (with 60 chromosomes): S. curtilobum. There are two major subspecies of Solanum tuberosum: andigena, or Andean; and tuberosum, or Chilean. The Andean potato is adapted to the short-day conditions prevalent in the mountainous equatorial and tropical regions where it originated; the Chilean potato, however, native to the Chiloé Archipelago, is adapted to the long-day conditions prevalent in the higher latitude region of southern Chile.
The International Potato Center, based in Lima, Peru, holds an ISO-accredited collection of potato germplasm. The international Potato Genome Sequencing Consortium announced in 2009 that they had achieved a draft sequence of the potato genome. The potato genome contains 12 chromosomes and 860 million base pairs, making it a medium-sized plant genome. More than 99 percent of all current varieties of potatoes currently grown are direct descendants of a subspecies that once grew in the lowlands of south-central Chile. Nonetheless, genetic testing of the wide variety of cultivars and wild species affirms that all potato subspecies derive from a single origin in the area of present-day southern Peru and extreme Northwestern Bolivia (from a species in the Solanum brevicaule complex). The wild Crop Wild Relatives Prebreeding project encourages the use of wild relatives in breeding programs. Enriching and preserving the gene bank collection to make potatoes adaptive to diverse environmental conditions is seen as a pressing issue due to climate change.
Most modern potatoes grown in North America arrived through European settlement and not independently from the South American sources, although at least one wild potato species, Solanum fendleri, naturally ranges from Peru into Texas, where it is used in breeding for resistance to a nematode species that attacks cultivated potatoes. A secondary center of genetic variability of the potato is Mexico, where important wild species that have been used extensively in modern breeding are found, such as the hexaploid Solanum demissum, as a source of resistance to the devastating late blight disease. Another relative native to this region, Solanum bulbocastanum, has been used to genetically engineer the potato to resist potato blight.
Potatoes yield abundantly with little effort, and adapt readily to diverse climates as long as the climate is cool and moist enough for the plants to gather sufficient water from the soil to form the starchy tubers. Potatoes do not keep very well in storage and are vulnerable to moulds that feed on the stored tubers and quickly turn them rotten, whereas crops such as grain can be stored for several years with a low risk of rot. The yield of Calories per acre (about 9.2 million) is higher than that of maize (7.5 million), rice (7.4 million), wheat (3 million), or soybean (2.8 million).
VARIETIES
There are close to 4,000 varieties of potato including common commercial varieties, each of which has specific agricultural or culinary attributes. Around 80 varieties are commercially available in the UK. In general, varieties are categorized into a few main groups based on common characteristics, such as russet potatoes (rough brown skin), red potatoes, white potatoes, yellow potatoes (also called Yukon potatoes) and purple potatoes.
For culinary purposes, varieties are often differentiated by their waxiness: floury or mealy baking potatoes have more starch (20–22%) than waxy boiling potatoes (16–18%). The distinction may also arise from variation in the comparative ratio of two different potato starch compounds: amylose and amylopectin. Amylose, a long-chain molecule, diffuses from the starch granule when cooked in water, and lends itself to dishes where the potato is mashed. Varieties that contain a slightly higher amylopectin content, which is a highly branched molecule, help the potato retain its shape after being boiled in water. Potatoes that are good for making potato chips or potato crisps are sometimes called "chipping potatoes", which means they meet the basic requirements of similar varietal characteristics, being firm, fairly clean, and fairly well-shaped.
The European Cultivated Potato Database (ECPD) is an online collaborative database of potato variety descriptions that is updated and maintained by the Scottish Agricultural Science Agency within the framework of the European Cooperative Programme for Crop Genetic Resources Networks (ECP/GR)—which is run by the International Plant Genetic Resources Institute (IPGRI).
PIGMENTATION
Dozens of potato cultivars have been selectively bred specifically for their skin or, more commonly, flesh color, including gold, red, and blue varieties that contain varying amounts of phytochemicals, including carotenoids for gold/yellow or polyphenols for red or blue cultivars. Carotenoid compounds include provitamin A alpha-carotene and beta-carotene, which are converted to the essential nutrient, vitamin A, during digestion. Anthocyanins mainly responsible for red or blue pigmentation in potato cultivars do not have nutritional significance, but are used for visual variety and consumer appeal. Recently, as of 2010, potatoes have also been bioengineered specifically for these pigmentation traits.
GENETICALLY ENGINEERED POTATOES
Genetic research has produced several genetically modified varieties. 'New Leaf', owned by Monsanto Company, incorporates genes from Bacillus thuringiensis, which confers resistance to the Colorado potato beetle; 'New Leaf Plus' and 'New Leaf Y', approved by US regulatory agencies during the 1990s, also include resistance to viruses. McDonald's, Burger King, Frito-Lay, and Procter & Gamble announced they would not use genetically modified potatoes, and Monsanto published its intent to discontinue the line in March 2001.
Waxy potato varieties produce two main kinds of potato starch, amylose and amylopectin, the latter of which is most industrially useful. BASF developed the Amflora potato, which was modified to express antisense RNA to inactivate the gene for granule bound starch synthase, an enzyme which catalyzes the formation of amylose. Amflora potatoes therefore produce starch consisting almost entirely of amylopectin, and are thus more useful for the starch industry. In 2010, the European Commission cleared the way for 'Amflora' to be grown in the European Union for industrial purposes only—not for food. Nevertheless, under EU rules, individual countries have the right to decide whether they will allow this potato to be grown on their territory. Commercial planting of 'Amflora' was expected in the Czech Republic and Germany in the spring of 2010, and Sweden and the Netherlands in subsequent years. Another GM potato variety developed by BASF is 'Fortuna' which was made resistant to late blight by adding two resistance genes, blb1 and blb2, which originate from the Mexican wild potato Solanum bulbocastanum. In October 2011 BASF requested cultivation and marketing approval as a feed and food from the EFSA. In 2012, GMO development in Europe was stopped by BASF.
In November 2014, the USDA approved a genetically modified potato developed by J.R. Simplot Company, which contains genetic modifications that prevent bruising and produce less acrylamide when fried than conventional potatoes; the modifications do not cause new proteins to be made, but rather prevent proteins from being made via RNA interference.
HISTORY
The potato was first domesticated in the region of modern-day southern Peru and extreme northwestern Bolivia between 8000 and 5000 BC. It has since spread around the world and become a staple crop in many countries.
The earliest archaeologically verified potato tuber remains have been found at the coastal site of Ancon (central Peru), dating to 2500 BC. The most widely cultivated variety, Solanum tuberosum tuberosum, is indigenous to the Chiloé Archipelago, and has been cultivated by the local indigenous people since before the Spanish conquest.
According to conservative estimates, the introduction of the potato was responsible for a quarter of the growth in Old World population and urbanization between 1700 and 1900. In the Altiplano, potatoes provided the principal energy source for the Inca civilization, its predecessors, and its Spanish successor. Following the Spanish conquest of the Inca Empire, the Spanish introduced the potato to Europe in the second half of the 16th century, part of the Columbian exchange. The staple was subsequently conveyed by European mariners to territories and ports throughout the world. The potato was slow to be adopted by European farmers, but soon enough it became an important food staple and field crop that played a major role in the European 19th century population boom. However, lack of genetic diversity, due to the very limited number of varieties initially introduced, left the crop vulnerable to disease. In 1845, a plant disease known as late blight, caused by the fungus-like oomycete Phytophthora infestans, spread rapidly through the poorer communities of western Ireland as well as parts of the Scottish Highlands, resulting in the crop failures that led to the Great Irish Famine. Thousands of varieties still persist in the Andes however, where over 100 cultivars might be found in a single valley, and a dozen or more might be maintained by a single agricultural household.
PRODUCTION
In 2016, world production of potatoes was 377 million tonnes, led by China with over 26% of the world total (see table). Other major producers were India, Russia, Ukraine and the United States. It remains an essential crop in Europe (especially eastern and central Europe), where per capita production is still the highest in the world, but the most rapid expansion over the past few decades has occurred in southern and eastern Asia.
NUTRITION
A raw potato is 79% water, 17% carbohydrates (88% is starch), 2% protein, and contains negligible fat (see table). In an amount measuring 100 grams, raw potato provides 322 kilojoules (77 kilocalories) of energy and is a rich source of vitamin B6 and vitamin C (23% and 24% of the Daily Value, respectively), with no other vitamins or minerals in significant amount (see table). The potato is rarely eaten raw because raw potato starch is poorly digested by humans. When a potato is baked, its contents of vitamin B6 and vitamin C decline notably, while there is little significant change in the amount of other nutrients.
Potatoes are often broadly classified as having a high glycemic index (GI) and so are often excluded from the diets of individuals trying to follow a low-GI diet. The GI of potatoes can vary considerably depending on the cultivar or cultivar category (such as "red", russet, "white", or King Edward), growing conditions and storage, preparation methods (by cooking method, whether it is eaten hot or cold, whether it is mashed or cubed or consumed whole), and accompanying foods consumed (especially the addition of various high-fat or high-protein toppings). In particular, consuming reheated or cooled potatoes that were previously cooked may yield a lower GI effect.
In the UK, potatoes are not considered by the National Health Service (NHS) as counting or contributing towards the recommended daily five portions of fruit and vegetables, the 5-A-Day program.
COMPARISON TO OTHER STAPLE FOODS
This table shows the nutrient content of potatoes next to other major staple foods, each one measured in its respective raw state, even though staple foods are not commonly eaten raw and are usually sprouted or cooked before eating. In sprouted and cooked form, the relative nutritional and anti-nutritional contents of each of these grains (or other foods) may be different from the values in this table. Each nutrient (every row) has the highest number highlighted to show the staple food with the greatest amount in a 100-gram raw portion.
TOXICITY
Potatoes contain toxic compounds known as glycoalkaloids, of which the most prevalent are solanine and chaconine. Solanine is found in other plants in the same family, Solanaceae, which includes such plants as deadly nightshade (Atropa belladonna), henbane (Hyoscyamus niger) and tobacco (Nicotiana spp.), as well as the food plants eggplant and tomato. These compounds, which protect the potato plant from its predators, are generally concentrated in its leaves, flowers, sprouts, and fruits (in contrast to the tubers). In a summary of several studies, the glycoalkaloid content was highest in the flowers and sprouts and lowest in the tuber flesh. (The glycoalkaloid content was, in order from highest to lowest: flowers, sprouts, leaves, skin, roots, berries, peel [skin plus outer cortex of tuber flesh], stems, and tuber flesh.)
Exposure to light, physical damage, and age increase glycoalkaloid content within the tuber. Cooking at high temperatures—over 170 °C—partly destroys these compounds. The concentration of glycoalkaloids in wild potatoes is sufficient to produce toxic effects in humans. Glycoalkaloid poisoning may cause headaches, diarrhea, cramps, and, in severe cases, coma and death. However, poisoning from cultivated potato varieties is very rare. Light exposure causes greening from chlorophyll synthesis, giving a visual clue as to which areas of the tuber may have become more toxic. However, this does not provide a definitive guide, as greening and glycoalkaloid accumulation can occur independently of each other.
Different potato varieties contain different levels of glycoalkaloids. The Lenape variety was released in 1967 but was withdrawn in 1970 as it contained high levels of glycoalkaloids. Since then, breeders developing new varieties test for this, and sometimes have to discard an otherwise promising cultivar. Breeders try to keep glycoalkaloid levels below 200 mg/kg). However, when these commercial varieties turn green, they can still approach solanine concentrations of 1000 mg/kg. In normal potatoes, analysis has shown solanine levels may be as little as 3.5% of the breeders' maximum, with 7–187 mg/kg being found. While a normal potato tuber has 12–20 mg/kg of glycoalkaloid content, a green potato tuber contains 250–280 mg/kg and its skin has 1500–2200 mg/kg.
GROWTH AND CULTIVATION
SEED POTATOES
Potatoes are generally grown from seed potatoes, tubers specifically grown to be free from disease and to provide consistent and healthy plants. To be disease free, the areas where seed potatoes are grown are selected with care. In the US, this restricts production of seed potatoes to only 15 states out of all 50 states where potatoes are grown. These locations are selected for their cold, hard winters that kill pests and summers with long sunshine hours for optimum growth. In the UK, most seed potatoes originate in Scotland, in areas where westerly winds prevent aphid attack and thus prevent spread of potato virus pathogens.
PHASES OF GROWTH
Potato growth is divided into five phases. During the first phase, sprouts emerge from the seed potatoes and root growth begins. During the second, photosynthesis begins as the plant develops leaves and branches. In the third phase, stolons develop from lower leaf axils on the stem and grow downwards into the ground and on these stolons new tubers develop as swellings of the stolon. This phase is often, but not always, associated with flowering. Tuber formation halts when soil temperatures reach 27 °C; hence potatoes are considered a cool-season, or winter, crop. Tuber bulking occurs during the fourth phase, when the plant begins investing the majority of its resources in its newly formed tubers. At this phase, several factors are critical to a good yield: optimal soil moisture and temperature, soil nutrient availability and balance, and resistance to pest attacks. The fifth and final phase is the maturation of the tubers: the plant canopy dies back, the tuber skins harden, and the sugars in the tubers convert to starches.
CHALLENGES
New tubers may start growing at the surface of the soil. Since exposure to light leads to an undesirable greening of the skins and the development of solanine as a protection from the sun's rays, growers cover surface tubers. Commercial growers cover them by piling additional soil around the base of the plant as it grows (called "hilling" up, or in British English "earthing up"). An alternative method, used by home gardeners and smaller-scale growers, involves covering the growing area with organic mulches such as straw or plastic sheets.
Correct potato husbandry can be an arduous task in some circumstances. Good ground preparation, harrowing, plowing, and rolling are always needed, along with a little grace from the weather and a good source of water. Three successive plowings, with associated harrowing and rolling, are desirable before planting. Eliminating all root-weeds is desirable in potato cultivation. In general, the potatoes themselves are grown from the eyes of another potato and not from seed. Home gardeners often plant a piece of potato with two or three eyes in a hill of mounded soil. Commercial growers plant potatoes as a row crop using seed tubers, young plants or microtubers and may mound the entire row. Seed potato crops are rogued in some countries to eliminate diseased plants or those of a different variety from the seed crop.
Potatoes are sensitive to heavy frosts, which damage them in the ground. Even cold weather makes potatoes more susceptible to bruising and possibly later rotting, which can quickly ruin a large stored crop.
PESTS
The historically significant Phytophthora infestans (late blight) remains an ongoing problem in Europe and the United States. Other potato diseases include Rhizoctonia, Sclerotinia, black leg, powdery mildew, powdery scab and leafroll virus.
Insects that commonly transmit potato diseases or damage the plants include the Colorado potato beetle, the potato tuber moth, the green peach aphid (Myzus persicae), the potato aphid, beet leafhoppers, thrips, and mites. The potato cyst nematode is a microscopic worm that thrives on the roots, thus causing the potato plants to wilt. Since its eggs can survive in the soil for several years, crop rotation is recommended.
During the crop year 2008, many of the certified organic potatoes produced in the United Kingdom and certified by the Soil Association as organic were sprayed with a copper pesticide to control potato blight (Phytophthora infestans). According to the Soil Association, the total copper that can be applied to organic land is 6 kg/ha/year.
According to an Environmental Working Group analysis of USDA and FDA pesticide residue tests performed from 2000 through 2008, 84% of the 2,216 tested potato samples contained detectable traces of at least one pesticide. A total of 36 unique pesticides were detected on potatoes over the 2,216 samples, though no individual sample contained more than 6 unique pesticide traces, and the average was 1.29 detectable unique pesticide traces per sample. The average quantity of all pesticide traces found in the 2,216 samples was 1.602 ppm. While this was a very low value of pesticide residue, it was the highest amongst the 50 vegetables analyzed.
HARVEST
At harvest time, gardeners usually dig up potatoes with a long-handled, three-prong "grape" (or graip), i.e., a spading fork, or a potato hook, which is similar to the graip but with tines at a 90° angle to the handle. In larger plots, the plow is the fastest implement for unearthing potatoes. Commercial harvesting is typically done with large potato harvesters, which scoop up the plant and surrounding earth. This is transported up an apron chain consisting of steel links several feet wide, which separates some of the dirt. The chain deposits into an area where further separation occurs. Different designs use different systems at this point. The most complex designs use vine choppers and shakers, along with a blower system to separate the potatoes from the plant. The result is then usually run past workers who continue to sort out plant material, stones, and rotten potatoes before the potatoes are continuously delivered to a wagon or truck. Further inspection and separation occurs when the potatoes are unloaded from the field vehicles and put into storage.
Immature potatoes may be sold as "creamer potatoes" and are particularly valued for taste. These are often harvested by the home gardener or farmer by "grabbling", i.e. pulling out the young tubers by hand while leaving the plant in place. A creamer potato is a variety of potato harvested before it matures to keep it small and tender. It is generally either a Yukon Gold potato or a red potato, called gold creamers or red creamers respectively, and measures approximately 2.5 cm in diameter. The skin of creamer potatoes is waxy and high in moisture content, and the flesh contains a lower level of starch than other potatoes. Like potatoes in general, they can be prepared by boiling, baking, frying, and roasting. Slightly older than creamer potatoes are "new potatoes", which are also prized for their taste and texture and often come from the same varieties.
Potatoes are usually cured after harvest to improve skin-set. Skin-set is the process by which the skin of the potato becomes resistant to skinning damage. Potato tubers may be susceptible to skinning at harvest and suffer skinning damage during harvest and handling operations. Curing allows the skin to fully set and any wounds to heal. Wound-healing prevents infection and water-loss from the tubers during storage. Curing is normally done at relatively warm temperatures 10 to 16 °C with high humidity and good gas-exchange if at all possible.
STORAGE
Storage facilities need to be carefully designed to keep the potatoes alive and slow the natural process of decomposition, which involves the breakdown of starch. It is crucial that the storage area is dark, ventilated well and, for long-term storage, maintained at temperatures near 4 °C. For short-term storage, temperatures of about 7 to 10 °C are preferred.
On the other hand, temperatures below 4 °C convert the starch in potatoes into sugar, which alters their taste and cooking qualities and leads to higher acrylamide levels in the cooked product, especially in deep-fried dishes. The discovery of acrylamides in starchy foods in 2002 has led to international health concerns. They are believed to be probable carcinogens and their occurrence in cooked foods is being studied for potentially influencing health problems.
Under optimum conditions in commercial warehouses, potatoes can be stored for up to 10–12 months. The commercial storage and retrieval of potatoes involves several phases: first drying surface moisture; wound healing at 85% to 95% relative humidity and temperatures below 25 °C; a staged cooling phase; a holding phase; and a reconditioning phase, during which the tubers are slowly warmed. Mechanical ventilation is used at various points during the process to prevent condensation and the accumulation of carbon dioxide.
When stored in homes unrefrigerated, the shelf life is usually a few weeks.
If potatoes develop green areas or start to sprout, trimming or peeling those green-colored parts is inadequate to remove copresent toxins, and such potatoes are no longer edible.
YIELD
The world dedicated 18.6 million ha in 2010 for potato cultivation. The average world farm yield for potato was 17.4 tonnes per hectare, in 2010. Potato farms in the United States were the most productive in 2010, with a nationwide average of 44.3 tonnes per hectare. United Kingdom was a close second.
New Zealand farmers have demonstrated some of the best commercial yields in the world, ranging between 60 and 80 tonnes per hectare, some reporting yields of 88 tonnes potatoes per hectare.
There is a big gap among various countries between high and low yields, even with the same variety of potato. Average potato yields in developed economies ranges between 38–44 tonnes per hectare. China and India accounted for over a third of world's production in 2010, and had yields of 14.7 and 19.9 tonnes per hectare respectively. The yield gap between farms in developing economies and developed economies represents an opportunity loss of over 400 million tonnes of potato, or an amount greater than 2010 world potato production. Potato crop yields are determined by factors such as the crop breed, seed age and quality, crop management practices and the plant environment. Improvements in one or more of these yield determinants, and a closure of the yield gap, can be a major boost to food supply and farmer incomes in the developing world.
USES
Potatoes are prepared in many ways: skin-on or peeled, whole or cut up, with seasonings or without. The only requirement involves cooking to swell the starch granules. Most potato dishes are served hot but some are first cooked, then served cold, notably potato salad and potato chips (crisps). Common dishes are: mashed potatoes, which are first boiled (usually peeled), and then mashed with milk or yogurt and butter; whole baked potatoes; boiled or steamed potatoes; French-fried potatoes or chips; cut into cubes and roasted; scalloped, diced, or sliced and fried (home fries); grated into small thin strips and fried (hash browns); grated and formed into dumplings, Rösti or potato pancakes. Unlike many foods, potatoes can also be easily cooked in a microwave oven and still retain nearly all of their nutritional value, provided they are covered in ventilated plastic wrap to prevent moisture from escaping; this method produces a meal very similar to a steamed potato, while retaining the appearance of a conventionally baked potato. Potato chunks also commonly appear as a stew ingredient. Potatoes are boiled between 10 and 25 minutes, depending on size and type, to become soft.
OTHER THAN FOR EATING
Potatoes are also used for purposes other than eating by humans, for example:
Potatoes are used to brew alcoholic beverages such as vodka, poitín, or akvavit.
They are also used as fodder for livestock. Livestock-grade potatoes, considered too small and/or blemished to sell or market for human use but suitable for fodder use, have been called chats in some dialects. They may be stored in bins until use; they are sometimes ensiled. Some farmers prefer to steam them rather than feed them raw and are equipped to do so efficiently.
Potato starch is used in the food industry as a thickener and binder for soups and sauces, in the textile industry as an adhesive, and for the manufacturing of papers and boards.
Maine companies are exploring the possibilities of using waste potatoes to obtain polylactic acid for use in plastic products; other research projects seek ways to use the starch as a base for biodegradable packaging.
Potato skins, along with honey, are a folk remedy for burns in India. Burn centres in India have experimented with the use of the thin outer skin layer to protect burns while healing.
Potatoes (mainly Russets) are commonly used in plant research. The consistent parenchyma tissue, the clonal nature of the plant and the low metabolic activity provide a very nice "model tissue" for experimentation. Wound-response studies are often done on potato tuber tissue, as are electron transport experiments. In this respect, potato tuber tissue is similar to Drosophila melanogaster, Caenorhabditis elegans and Escherichia coli: they are all "standard" research organisms.
Potatoes have been delivered with personalized messages as a novelty. Potato delivery services include Potato Parcel and Mail A Spud.

Polar Bear
"Region: America
Class: Mammalia
Order: Carnivora
Family: Ursidae
Genus: Ursus
Scientific Name: Ursus maritimus
Description : Polar bears are considered the largest land carnivores in the world, matched only by very large individual Kodiak brown bears. Both sexes differ in size throughout their range; males being much larger than females and continuing to grow for a longer period of time. These bears have long, massive skulls, necks and bodies with long legs and large paws. Ears and tail are short. The nose is more prominent or “Roman” with a black rhinarium (nose pad). The tongue is black and the eyes brown. The surface of the skin is also black. Fur colour varies slightly with the season: new coats grown just prior to the winter season are very white appearing as slightly creamy white against the stark white of their icy winter environment. This pelage is thick, coarse and long with dense underfur. Guard hairs, found throughout the pelage, are shiny, almost glossy, oily and waterproof and have hollow shafts. Polar bears moult annually between the end of May and August. The coat becomes thinner and has a yellow wash or is almost a golden colour. Male polar bears weigh between 400 – 600 kg, and have been recorded up to a maximum of 800 kg. Females are smaller than the males weighing up to 300 kg, and when pregnant up to 460 kg. Polar bears are 2.5 – 3.5 m long.
Distribution : The polar bear is circumpolar in distribution, inhabiting all Arctic seas and coastlines. It is found on the pack-ice off the Alaskan coast north of Bering Strait, off the coasts of Greenland and along the Eurasian Arctic coast from Spitsbergen to Wrangell Island. Rare stragglers reach Iceland. Individual bears have been seen on the frozen Arctic Ocean as far as latitude 88 degrees North, only 2 degrees from the North Pole. In Canada, they are found along the Arctic coasts from Alaska to Labrador and from the tip of James Bay to northern Ellesmere Island. Polar bears do roam as far as 150 kilometres inland into the coniferous forests, where they live very differently from the polar bears which belong to the high Arctic.
Habitat : They prefer areas of annual ice, which they use as a hunting platform and protective cover. This includes snow-drifted pressure ridges, refrozen cracks and areas of open water surrounded by ice. In areas where the pack ice melts by mid to late summer they come inland and live in coniferous forest areas. Here they remain until the ice re-freezes. Areas of solidly frozen sea ice and the open seas are avoided. Generally they are most common along coastal areas. Some do enter the permanent pack ice.
Food : The ringed seal is by far the most common prey. They also eat bearded seal, harp seal and hooded seal. Young walrus are sometimes taken. During the summer months they feed upon the shoreline carrion, fish, mussels, crabs, starfish, lemmings and the eggs and nestling young of waterfowl and cliff-dwelling birds. They will also graze on kelp, grasses and eat mushrooms and crowberries.
Reproduction and Development : Normally they are solitary animals outside the breeding season, the exception being a mother with cubs. Polar bears mate in mid-summer. Females first start to breed at 3 to 5 years of age. In April and May adult females are in oestrus and ready to accept a mate. They are polyandrous, meaning one female will mate with more than one male in one breeding season. Males fight among themselves for the female’s attention and a couple will pair off for a period of a few days to two weeks. With females, delayed implantation occurs, the fertilized egg does not implant in the uterus until mid-September to mid-October. Embryonic development begins at this time. Gestation periods, therefore, vary a great deal when including this period of delay. Females choose suitable locations to build their maternity dens in mid-October and retreat to them for the winter season. They give birth to one to four cubs somewhere between late November and early January. Twins are most common. The newborns are small; 25 to 30 cm long and weigh less than 1 kg. They are covered with very fine hair, appearing almost naked and their eyes are closed. Their eyes open at 6 weeks. Growth is very quick; at two months their fur has thickened; they weigh about 5 kg and move about the den. By mid-March to early April, when the den is opened, the cubs weigh about 10 kg and are surprisingly strong. The cubs suckle for nine months, occasionally one year. They are very dependent on their mother and stay with her for two years. At that time they weigh 90 - 180 kg and are half grown.
Adaptations : Polar bears are wonderfully adapted to their Arctic surroundings.
Locomotion. On land a shuffling walk may be increased to a rolling gallop of 40 km/h and can outrun caribou over a short distance. Bears are often seen standing high on their hind legs, necks stretched to scan the landscape. On thin ice, legs are spread to distribute body mass. Thickly padded and furred soles allow the bear to move quietly as well as providing good traction. Small bumps and cavities on the soles act like suction cups keeping bears from slipping on the ice. The claws are used to dig into icy slopes and to grip prey. They are strong swimmers, paddling with their forefeet only and trailing their hind feet which act as a rudder. They can stay submerged for over one minute, keeping their eyes open. They swim at a speed of approximately 6.4 km/h, often covering long distances.
Insulation. Polar bears have a thick layer of sub-cutaneous fat and very dense underfur with several layers of glossy guard hair on the outside. Their pelt is much thicker in winter and provides excellent insulation. The fat layer also adds to buoyancy in the water. Water is shed easily from the oily waterproof fur. Small, furry ears have a heavy network of blood vessels, keeping them warm and conserving heat. The tail is short and rounded also conserving heat. Fur is very dense around the soles of the feet.
Pelage. The creamy white appearance of the coat allows the bear to be inconspicuous when hunting seal. Each hair is similar to an optical fibre; colourless and hollow. Being translucent, it reflects the heat from the sun down to the base of the hair, where it is absorbed by the black skin. Whiteness comes from reflection of light rather than pigmentation.
Hunting. Bears use their keen sense of smell to detect seal breathing holes. These can be up to a kilometer away and covered by a layer of snow and ice. They will stand or lie by the seal’s blowhole in the ice for hours; they may swim towards seals resting on the ice flows with only their nose showing above the water. They will dive quietly, then swim up to the ice edge and jump out on the seal, and will also crawl towards a sunbathing seal using every piece of raised ice to conceal the approach.
Denning. Both sexes occupy dens for shelter. Topographic factors influence the den sites. In Canadian core areas, dens frequently occur on south-facing slopes where northerly prevailing winds create the best drifts, where the wind-chill is least and insulation from received solar radiation is greatest. One of the three largest denning areas worldwide is in Canada. There are three main types of winter refuges: maternity dens, temporary dens and winter shelters. During the winter any bear may dig a temporary den and use it for a few days during a storm, or take shelter in a natural cavity. Winter shelters are used for longer periods of time as resting places. This type of shelter is usually roomier with additional features such as alcoves, porches and ventilation holes. Bears do not hibernate in the strict sense of the word; they have the ability to slow down their metabolism to conserve energy at any time of year. The state of self-induced lethargy while in the shelter allows them to preserve their vital fat reserves. During this time, the body temperature of the polar bear decreases by a few degrees from normal and the respiration rates are markedly reduced. Maternity dens are built and occupied by pregnant females and can vary in size. The denning chamber is at the upper end of an entrance tunnel 1 to 2 m long. It averages 1.5 m in diameter with a height of 90 to 100cm in the middle. Drifting snow seals the entrance. The chamber is higher than the tunnel, trapping bear body heat inside. Dens not only provide a safe place to give birth to her cubs, but are also a place of protection for the cubs during their first few months. During this time she does not leave the den, remaining with her cubs and living on her reserves of fat. In the spring, with her fat severely depleted she must leave to find food to sustain herself and her cubs. After they leave the maternity den she will build temporary refuges in which to nurse, rest and shelter her young cubs and warms them as they all sleep together. She heads with her cubs towards the nearest supply of food, this is usually pack ice.
Sight and sounds. Polar bears have good eyesight. Their eyes have inner eyelids that keep the glare of the sun on snow and ice from blinding them. When defending a food source from other bears they use a deep growl. They hiss and snort to show aggression. Angry bears use loud roars and growls. Mothers scold cubs with a low growl.
Threats to Survival : Polar bears are one of the animals most threatened by global warming. They depend entirely on sea ice as a platform from which to hunt seals. Reduction of the total ice cover in the Arctic is a serious concern globally. When the ice does not form or forms too late in the season many polar bears starve. In Hudson Bay, scientists have found the main cause of death for cubs to be either lack of food or lack of fat on nursing mothers. Exploitation of minerals and fossil fuels in the Arctic pose a continuous threat. Of the oil and natural gas deposits globally, 20% are located in the Arctic. As the ice cap recedes these become more accessible. Countries are competing which each other in claiming ownership of Arctic and its resources. This can only result in further and more drastic impact on polar bear habitat.

White Tiger or Bengal Tiger (Panthera tigris)
The white tiger is a pigmentation variant of the Bengal tiger, which is reported in the wild from time to time in States of India like Assam, Bengal, Bihar,Sunderbans and especially in the former State of Rewa.
Variation
The White Bengal tigers are distinctive for their color fur. According to the website, “Animal Corner,” the correct term to name the white tiger is Chinchilla albinistic. The white fur is due to the lack of pheomelanin pigment, which is found in Bengal tigers with orange color fur. When compared to Bengal tigers, the white Bengal tigers tend to grow faster and heavier than the orange Bengal tiger. They also tend to be somewhat bigger at birth, and as fully grown adults. White Bengal tigers are fully grown when they are 2–3 years of age. White male tigers reach weights of 200 to 230 kilograms and up to 3 meters in length. Similar to zebras, the white Bengal tiger’s stripes are like fingerprints, no two tigers have the same. Also, the stripes of the tiger are a pigmentation of the skin.
For a white Bengal tiger to be born, both parents must carry the unusual gene for white colouring, which, according to the website “Animal Corner,” only happens naturally about once in 10,000 births. As stated by Kailash Sankhala, the director of the New Delhi Zoo in the 1960s, “one of the functions of the white gene tiger may have been to keep a size gene in the population, in case it's ever needed." Dark-striped white individuals are well-documented in the Bengal tiger subspecies, also known as the Royal Bengal or Indian tiger (Panthera tigris tigris or P. t. bengalensis), and may also have occurred in captive Siberian tigers (Panthera tigris altaica)[citation needed], as well as having been reported historically in several other subspecies.
Currently, several hundred white tigers are in captivity worldwide, with about one hundred being found in India. Nevertheless, their population is on the increase. Nandankanan in the state of Odisha, India, is the host zoo for white tigers. In 1980, the first litter of white tigers were born to Deepak and Ganga, two normal tawny tigers. Subsequent litters of white tigers have been distributed to zoos both at home and abroad. Currently, Nandankanan is home to over 34 white tigers. Their unique white color fur has made them popular in entertainment showcasing exotic animals, and at zoos. German-American magicians Siegfried & Roy became famous for breeding and training two white tigers for their performances, referring to them as "royal white tigers," the white tiger's association with the Maharaja of Rewa. The first white Bengal tiger was found in India by royalty Maharaja Shri Martand Singh of Rewa. According to the website, “Animal Corner”, in 1948, Maharaja killed the white tigress leaving four cubs behind. Later, the cubs of the dead tigress were shot except for the white cub. It is believed that all white Bengal tigers are descendants of this cub.
White Siberian tigers
The existence of white Siberian tigers has not been scientifically documented, despite occasional unsubstantiated reports of sightings of white tigers in the regions where wild Siberian tigers live. It may be that the white mutation does not exist in the wild Siberian tiger population: no white Siberian tigers have been born in captivity, despite the fact that the subspecies has been extensively bred during the last few decades (with much outbreeding between the different Siberian lineages for purposes of conservation genetics); a recessive allele should occasionally turn up in a homozygous state during such breeding, and in this particular case yield white tigers from normally-colored parents, but no such animals have been reported.
The famous white Siberian tigers found in captivity are actually not pure Siberian tigers. They are instead the result of Siberian tigers breeding with Bengal tigers. The gene for white coating is quite common among Bengal tigers, but the natural birth of a white Bengal tiger is still a very rare occasion in the wild, where white tigers are not bred selectively.
The white tiger is not considered a tiger subspecies, but rather a hybrid mutant variant of the existing tiger subspecies. If a pure white Siberian tiger were to be born, it would therefore not be selectively bred within the tiger conservation programs. It would, however, probably still be selectively bred outside the program in an effort to create more white Siberian tigers. Due to the popularity of white tigers, they are used to attract visitors to zoos. White tigers are found in zoos in China commonly. White Tigers are very large. They can weigh up to 300 kg and reach more than 4 meters of length.
Stripeless white tigers and golden tabby tiger
An additional genetic condition can remove most of the striping of a white tiger, making the animal almost pure white. One such specimen was exhibited at Exeter Change in England in 1820, and described by Georges Cuvier as "A white variety of Tiger is sometimes seen, with the stripes very opaque, and not to be observed except in certain angles of light." Naturalist Richard Lydekker said that, "a white tiger, in which the fur was of a creamy tint, with the usual stripes faintly visible in certain parts, was exhibited at the old menagerie at Exeter Change about the year 1820." Hamilton Smith said, "A wholly white tiger, with the stripe-pattern visible only under reflected light, like the pattern of a white tabby cat, was exhibited in the Exeter Change Menagerie in 1820.", and John George Wood stated that, "a creamy white, with the ordinary tigerine stripes so faintly marked that they were only visible in certain lights." Edwin Henry Landseer also drew this tigress in 1824.
The modern strain of snow white tigers came from repeated brother–sister matings of Bhim and Sumita at Cincinnati Zoo. The gene involved may have come from a Siberian tiger, via their part-Siberian ancestor Tony. Continued inbreeding appears to have caused a recessive gene for stripelessness to show up. About one fourth of Bhim and Sumita's offspring were stripeless. Their striped white offspring, which have been sold to zoos around the world, may also carry the stripeless gene. Because Tony's genome is present in many white tiger pedigrees, the gene may also be present in other captive white tigers. As a result, stripeless white tigers have appeared in zoos as far afield as the Czech Republic (Liberec), Spain and Mexico. Stage magicians Siegfried & Roy were the first to attempt to selectively breed tigers for stripelessness; they owned snow-white Bengal tigers taken from Cincinnati Zoo (Tsumura, Mantra, Mirage and Akbar-Kabul) and Guadalajara, Mexico (Vishnu and Jahan), as well as a stripeless Siberian tiger called Apollo.
In 2004, a blue-eyed, stripeless white tiger was born in a wildlife refuge in Alicante, Spain. Its parents are normal orange Bengals. The cub was named Artico ("Arctic").
Stripeless white tigers were thought to be sterile until Siegfried & Roy's stripeless white tigress Sitarra, a daughter of Bhim and Sumita, gave birth. Another variation which came out of the white strains were unusually light-orange tigers called "golden tabby tigers". These are probably orange tigers which carry the stripeless white gene as a recessive. Some white tigers in India are very dark, between white and orange.
Genetics
A white tiger's pale coloration is due to the lack of the red and yellow pigments that normally produce the orange color. This had long been thought to be due to a mutation in the gene for the tyrosinase enzyme. A knockout mutation in this gene results in albinism, the inability to make either pheomelanin or eumelanin, while the consequence of a less severe mutation in the same gene is the cause of a selective loss of pheomelanin, the so-called Chinchilla trait. The white phenotype in tigers had been attributed to this Chinchilla mutation in tyrosinase, and some publications prior to the 1980s refer to it as an albino gene for this reason.[citation needed] However, genomic analysis has demonstrated instead that a mutation in the SLC45A2 gene is responsible. The resultant single amino acid substitution in this transport protein, by a mechanism yet to be determined, causes the elimination of pheomelanin expression seen in the white tiger. This is a recessive trait, meaning that it is only seen in individuals that are homozygous for this mutation. Inbreeding promotes recessive traits and has been used as a strategy to produce white tigers in captivity.
The stripe color varies due to the influence and interaction of other genes. Another genetic characteristic makes the stripes of the tiger very pale; white tigers of this type are called snow-white or "pure white". White tigers, Siamese cats, and Himalayan rabbits have enzymes in their fur which react to temperature, causing them to grow darker in the cold. A white tiger named Mohini was whiter than her relatives in the Bristol Zoo, who showed more cream tones. This may have been because she spent less time outdoors in the winter. White tigers produce a mutated form of tyrosinase, an enzyme used in the production of melanin, which only functions at certain temperatures, below 37 °C (99 °F). This is why Siamese cats and Himalayan rabbits are darker on their faces, ears, legs, and tails (the color points), where the cold penetrates more easily. This is called acromelanism, and other cats breeds derived from the Siamese, such as the Himalayan and the snowshoe cat, also exhibit the condition. Kailash Sankhala observed that white tigers were always whiter in Rewa State, even when they were born in New Delhi and returned there. "In spite of living in a dusty courtyard, they were always snow white." A weakened immune system is directly linked to reduced pigmentation in white tigers.
Genetic defects
Outside of India, inbred white tigers have been prone to crossed eyes, a condition known as strabismus, an example of which is "Clarence the cross-eyed lion", due to incorrectly routed visual pathways in the brains of white tigers. When stressed or confused, all white tigers cross their eyes. Strabismus is associated with white tigers of mixed Bengal x Siberian ancestry. The only pure-Bengal white tiger reported to be cross-eyed was Mohini's daughter Rewati. Strabismus is directly linked to the white gene and is not a separate consequence of inbreeding. The orange litter-mates of white tigers are not prone to strabismus. Siamese cats and albinos of every species which have been studied all exhibit the same visual pathway abnormality found in white tigers. Siamese cats are also sometimes cross-eyed, as are some albino ferrets. The visual pathway abnormality was first documented in white tigers in the brain of a white tiger called Moni after he died, although his eyes were of normal alignment. The abnormality is that there is a disruption in the optic chiasm. The examination of Moni's brain suggested the disruption is less severe in white tigers than it is in Siamese cats. Because of the visual pathway abnormality, by which some optic nerves are routed to the wrong side of the brain, white tigers have a problem with spatial orientation, and bump into things until they learn to compensate. Some tigers compensate by crossing their eyes. When the neurons pass from the retina to the brain and reach the optic chiasma, some cross and some do not, so that visual images are projected to the wrong hemisphere of the brain. White tigers cannot see as well as normal tigers and suffer from photophobia, like albinos.
Other genetic problems include shortened tendons of the forelegs, club foot, kidney problems, arched or crooked backbone and twisted neck. Reduced fertility and miscarriages, noted by ”tiger man” Kailash Sankhala in pure-Bengal white tigers were attributed to inbreeding depression. A condition known as "star-gazing" (the head and neck are raised almost straight up, as if the affected animal is gazing at the stars), which is associated with inbreeding in big cats, has also been reported in white tigers. Some white tigers born to North American lines have bulldog faces with a snub nose, jutting jaw, domed head and wide-set eyes with an indentation between the eyes. However, some of these traits may be linked to poor diet rather than inbreeding.
There was a 450 lb (200 kg) male cross-eyed white tiger at the Pana'ewa Rainforest Zoo in Hawaii, which was donated to the zoo by Las Vegas magician Dirk Arthur. There is a picture of a white tiger which appears to be cross-eyed on just one side in Siegfried & Roy's book Mastering The Impossible. A white tiger, named Scarlett O'Hara, who was Tony's sister, was cross-eyed only on the right side.
A male white tiger named Cheytan, a son of Bhim and Sumita born at the Cincinnati Zoo, died at the San Antonio Zoo in 1992 from anaesthesia complications during root canal therapy. It appears that white tigers also react strangely to anaesthesia. The best drug for immobilizing a tiger is CI 744, but a few tigers, white ones in particular, undergo a re-sedation effect 24–36 hours later. This is due to their inability to produce normal tyrosinase, a trait they share with albinos, according to zoo veterinarian David Taylor. He treated a pair of white tigers from the Cincinnati Zoo at Fritz Wurm's safari park in Stukenbrock, Germany, for salmonella poisoning, which reacted strangely to the anaesthesia.
Mohini was checked for Chédiak-Higashi syndrome in 1960, but the results were inconclusive. This condition is similar to albino mutations and causes bluish lightening of the fur color, crossed eyes, and prolonged bleeding after surgery. Also, in the event of an injury, the blood is slow to coagulate. This condition has been observed in domestic cats, but there has never been a case of a white tiger having Chédiak-Higashi syndrome. There has been a single case of a white tiger having central retinal degeneration, reported from the Milwaukee County Zoo, which could be related to reduced pigmentation in the eye. The white tiger in question was a male named Mota on loan from the Cincinnati Zoo.
There is a myth that white tigers have an 80% infant mortality rate. However, the infant mortality rate for white tigers is no higher than it is for normal orange tigers bred in captivity. Cincinnati Zoo director Ed Maruska said: "We have not experienced premature death among our white tigers. Forty-two animals born in our collection are still alive. Mohan, a large white tiger, died just short of his 20th birthday, an enviable age for a male of any subspecies, since most males live shorter captive lives. Premature deaths in other collections may be artifacts of captive environmental conditions...in 52 births we had four stillbirths, one of which was an unexplained loss. We lost two additional cubs from viral pneumonia, which is not excessive. Without data from non-inbred tiger lines, it is difficult to determine whether this number is high or low with any degree of accuracy."Ed Maruska also addressed the issue of deformities: "Other than a case of hip dysplasia that occurred in a male white tiger, we have not encountered any other body deformities or any physiological or neurological disorders. Some of these reported maladies in mutant tigers in other collections may be a direct result of inbreeding or improper rearing management of tigers generally."
Inbreeding and outcrossing
Because of the extreme rarity of the white tiger allele in the wild,[9] the breeding pool was limited to the small number of white tigers in captivity. According to Kailash Sankhala, the last white tiger ever seen in the wild was shot in 1958. Today there is a large number of white tigers in captivity. A white Amur tiger may have been born at Center Hill and has given rise to a strain of white Amur tigers. A man named Robert Baudy realized that his tigers had white genes when a tiger he sold to Marwell Zoo in England developed white spots, and bred them accordingly. The Lowry Park Zoo in Tampa Bay has four of these white Amur tigers, descended from Robert Baudy's stock.
It has also been possible to expand the white-gene pool by outcrossing white tigers with unrelated orange tigers and then using the cubs to produce more white tigers. The white tigers Ranjit, Bharat, Priya and Bhim were all outcrossed, in some instances to more than one tiger. Bharat was bred to an unrelated orange tiger named Jack from the San Francisco Zoo and had an orange daughter named Kanchana. Bharat and Priya were also bred with an unrelated orange tiger from Knoxville Zoo, and Ranjit was bred to this tiger's sister, also from Knoxville Zoo. Bhim fathered several litters with an unrelated orange tigress named Kimanthi at the Cincinnati Zoo. ankam Ranjeeth had several mates at the Omaha Zoo.
The last descendants of Bristol Zoo's white tigers were a group of orange tigers from outcrosses which were bought by a Pakistani senator and shipped to Pakistan. Rajiv, Pretoria Zoo's white tiger, who was born in the Cincinnati Zoo, was also outcrossed and sired at least two litters of orange cubs at Pretoria Zoo. Outcrossing is not necessarily done with the intent of producing more white cubs by resuming inbreeding further down the line.
Outcrossing is a way of bringing fresh blood into the white strain. The New Delhi Zoo loaned out white tigers to some of India's better zoos for outcrossing, and the government had to impose a whip to force zoos to return either the white tigers or their orange offspring.
Siegfried & Roy performed at least one outcross. In the mid-1980s they offered to work with the Indian government in the creation of a healthier strain of white tigers. The Indian government reportedly considered the offer; however, India had a moratorium on breeding white tigers after cubs were born at New Delhi Zoo with arched backs and clubbed feet, necessitating euthanasia. Siegfried & Roy have bred white tigers in collaboration with the Nashville Zoo.
Because of the inbreeding and resulting genetic defects the Association of Zoos and Aquariums barred member zoos from breeding white tigers, white lions and king cheetahs in a white paper adopted by the board of directors in July 2011. It is noteworthy that the first person to speak out against the displaying of white tigers was William G. Conway, General Director of the New York Zoological Society, which later became known as the Wildlife Conservation Society when he said, "White tigers are freaks. It's not the role of a zoo to show two headed calves and white tigers." He warned AZA in 1983 of the harm to the zoo's credibility in catering to the public's fascination with freaks, but went unheeded until 2008 when AZA issued a request to their members to stop breeding white tigers and then later in July 2011 when the AZA formally adopted that stance as policy. Conway was attacked by Ed Maruska of the Cincinnati Zoo for his observation, but in the end Conway's belief was validated.
A complete scan of the genome led to the discovery that the white tiger’s distinguishing characteristic arises from a single naturally occurring mutation, the substitution of one amino acid for another—valine for alanine—in the protein identified as SLC45A2. The implication of this discovery means that white tigers can be bred from any colored Bengal tiger pair possessing the unique but naturally occurring recessive gene.
Popular culture
White tigers appear frequently in literature, video games, television, and comic books. Such examples include the Swedish rock band Kent, which featured a white tiger on the cover of their best-selling album Vapen & ammunition in 2002. This was a tribute to the band's home town Eskilstuna, as the local zoo in town had white tigers from the Hawthorn Circus as its main attraction. The white tiger has also been featured in the video for the song "Human" by the popular American synth-rock band The Killers. White Tiger is also the name of an American glam metal band from the 1980s.
In the live action version of Disney's 101 Dalmatians, Cruella de Vil kills a white tiger for its fur.
- Seto Bagh (or White tiger in English) is a Nepali language novel by Diamond - Shumsher Rana about an encounter with a white tiger.
- Aravind Adiga's novel The White Tiger won the Man Booker Prize in 2008. The central character and narrator refers to himself as "The White Tiger". It was a nickname given to him as a child to denote that he was unique in the "jungle" (his hometown), that he was smarter than the others.
- Video games including white tigers include Zoo Tycoon, the Warcraft universe, and Perfect World International. White Tigers are featured as a wild, tamable "pet" companion in Guild Wars Factions. White tigers are also seen in Heroes of Might and Magic IV. The protector of the mystical world of Shangri-La in Far Cry 4 is a white tiger that allies with the protagonist to defeat demons.
- Both the Power Rangers and the Japanese Super Sentai series from which the Power Rangers series is based on, have used White Tiger themed mecha. A trained white tiger from the Bowmanville Zoo in Ontario, Canada, was used in the Animorphs TV series. A superhero named White Tiger appears in "The Justice Friends" on Dexter's Laboratory.
- Marvel Comics also publishes several superheroes who go by the name White Tiger. A white tiger named White Blaze is frequently shown in the anime Ronin Warriors.
- Tigatron from the animated TV series Transformers: Beast Wars is based on the white tiger. There have been at least 4 heroes in Marvel comics called "The White Tiger": two gained powers from a group of three mystic amulets that they possessed, one was actually a tigress evolved by the High Evolutionary, and one was given an artificial version of the "Black Panther's Heart Shaped Herb".

Litorea caerulea
From Wikipedia -
The Australian Green Tree Frog, simply Green Tree Frog in Australia, White's Tree Frog, or Dumpy Tree Frog (Litoria caerulea) is a species of tree frog native to Australia and New Guinea, with introduced populations in New Zealand and the United States. The species belongs to the genus Litoria. It is physiologically similar to some species of the genus, particularly the Magnificent Tree Frog (Litoria splendida) and the Giant Tree Frog (Litoria infrafrenata).
The Green Tree Frog is larger than most Australian frogs, reaching 10 centimetres (4 inches) in length. The average lifespan of the frog in captivity, about sixteen years, is long in comparison with most frogs. Green Tree Frogs are docile and well suited to living near human dwellings. They are often found on windows or inside houses, eating insects drawn by the light.
Due to its physical and behavioural traits, the Green Tree Frog has become one of the most recognisable frogs in its region, and is a popular exotic pet throughout the world. The skin secretions of the frog have antibacterial and antiviral properties that may prove useful in pharmaceutical preparations.
The Green Tree Frog shares the Litoria genus with dozens of frog species endemic to Australasia. The common name of the species, "White's Tree Frog", is in honour of John White's first description in 1790. The Green Tree Frog was the first Australian frog scientifically classified.
The species was originally called the "blue frog" (Rana caerulea) despite its green colour. The original specimens White sent to England were damaged by the preservative and appeared blue. The colour of the frog is caused by blue and green pigments covered in a yellow layer; the preservative destroyed the yellow layer and left the frog with a blue appearance. The specific epithet, caerulea, which is Latin for blue, has remained. The frog is also known more simply as the "Green Tree Frog." However, that name is often given to the most common large green tree frog in a region, for example, the American green tree frog (Hyla cinerea).
The Green Tree Frog can grow up to 10 centimeters (4 inches) in length. Its color depends on the temperature and color of the environment, ranging from brown to green; the ventral surface is white. The frog occasionally has small, white, irregularly shaped spots on its back, up to five millimeters in diameter, which increase in number with age. The frog has large discs at the end of its toes, of about five millimeters in diameter at maturity. These help the frogs grip while climbing and allow them to climb vertically on glass. The eyes are golden and have horizontal irises, typical of the Litoria genus. The fingers are about one-third webbed, and the toes nearly three-quarters webbed. The tympanum (a skin membrane similar to an eardrum) is visible.
The Green Tree Frog is sometimes confused with the Magnificent Tree Frog (Litoria splendida), which inhabits only north-western Australia and can be distinguished by the presence of large parotoids and rostral glands on the head. The Giant Tree Frog (Litoria infrafrenata) is also sometimes confused with the Green Tree Frog. The main difference is a distinct white stripe along the edge of the lower jaw of the Giant Tree Frog, which is not present in the Green Tree Frog.
The tadpole's appearance changes throughout its development. The length of the species' tadpoles ranges from 8.1 millimeters (once hatched) to 44 millimeters. They are initially mottled with brown, which increases in pigmentation (to green or brown) during development. The underside begins dark and then lightens, eventually to white in adults. The eggs are brown, in a clear jelly and are 1.1–1.4 millimeters in diameter.
Although frogs have lungs, they absorb oxygen through their skin, and for this to occur efficiently, the skin must be moist. A disadvantage of moist skin is that pathogens can thrive on it, increasing the chance of infection. To counteract this, frogs secrete peptides that destroy these pathogens. The skin secretion from the Green Tree Frog contains caerins, a group of peptides with antibacterial and antiviral properties. It also contains caerulins, which have the same physiological effects as CCK-8, a digestive hormone and hunger suppressant. Several peptides from the skin secretions of the Green Tree Frog have been found to destroy HIV without harming healthy T-cells.
The Green Tree Frog is native to northern and eastern regions of Australia and to southern New Guinea. Distribution is limited mostly to areas with a warm, wet tropical climate. In New Guinea, the Green Tree Frog is restricted to the drier, southern region. Its range spans from Irian Jaya to Port Moresby, and is most abundant on Daru Island. There have been isolated records in northern New Guinea, however this is thought to have been through introduction by humans. The International Conservation Union (IUCN) suggests "scattered locations" in both New Guinea and Indonesia.
The species has been introduced to both the United States and New Zealand. In the United States, it is restricted to two regions within Florida, where it was possibly introduced through the pet trade. Only small populations have been found in Florida, and it is unknown whether they have caused any ecological damage as an invasive species. In New Zealand, a population was once present; however, there have been no sightings since the 1950s.
Green Tree Frogs are very docile. They are nocturnal and come out in early evenings to call (in spring and summer) and hunt at night. During the day they find cool, dark, and moist areas to sleep. During winter, Green Tree Frogs do not call and are not usually seen.
Depending on their location, Green Tree Frogs occupy various habitats. Typically, they are found in the canopy of trees near a still-water source. However, they can survive in swamps (among the reeds) or in grasslands in cooler climates. Green Tree Frogs are well known for inhabiting water sources inside houses, such as sinks or toilets. They can also be found on windows eating insects. They will occupy tanks (cisterns), downpipes (downspouts), and gutters, as these have a high humidity and are usually cooler than the external environment. The frogs are drawn to downpipes and tanks during mating season, as the fixtures amplify their call.
The species' call is a low, slow Brawk-Brawk-Brawk, repeated many times. For most of the year, they call from high positions, such as trees and gutters. During mating season the frogs descend, although remaining slightly elevated, and call close to still-water sources, whether temporary or permanent. Like many frogs, Green Tree Frogs call not only to attract a mate. They have been observed calling to advertise their location outside the mating season, usually after rain, for reasons that are uncertain to researchers. They will emit a stress call whenever they are in danger, such as when predators are close or when a person steps on a log in which a frog resides.
The species' diet consists mainly of insects and spiders, but can include smaller frogs and even small mammals. Frog teeth are not suited to cutting up prey, so the prey must fit inside the mouth of the frog. Many frogs propel their sticky tongues at prey. The prey sticks, and is consumed. A Green Tree Frog will use this technique for smaller prey; however for larger prey, it pounces, then forces the prey into its mouth with its hands.
The frog has a few native predators, among them snakes and a few species of lizards and birds. Since the European settlement of Australia, non-native predators have been introduced, primarily dogs and cats. The species has an average life expectancy in captivity of sixteen years, but some have been known to live for over twenty years, which is long for a frog. The average life expectancy in the wild is lower than in captivity, due to predation.
As a pet
The Green Tree Frog is one of the most popular pet frogs throughout the world. Its docile nature, often cartoon-like appearance, and long life expectancy make it an attractive choice for exotic-pet owners. It is also one of the easier frogs to care for: their diet is broad and they have a strong resistance to disease. One problem commonly associated with keeping this species as a pet is overfeeding; Green Tree Frogs tend to become obese if overfed. In the wild, exertion of energy is required for a frog to capture its prey. However, in captivity they are usually given live feed in a confined space. This lessens the activity needed for feeding, resulting in weight gain. An overweight member of the species will deposit fat layers over the top of the head and body, giving it "dumpy" appearance. Thus the name, "Dumpy Tree Frog."
Conservation
Australian law gives protected status to the Green Tree Frog - along with all Australian fauna - under the federal Environment Protection and Biodiversity Conservation Act 1999. The IUCN lists it as a "least concern" species, given its broad range and population, balanced habitats, and because it is likely not declining fast enough for more threatened status.
Much of the Green Tree Frog's natural habitat has been destroyed. Also, some of the frogs have been found infected with chytrid fungus (causing chytridiomycosis). These two factors associated with the general decline in frog populations in Australia threaten to reduce the population of the Green Tree Frog. However, because of the long life expectancy of this species, any effects of a reduced reproduction rate will take longer to spot than they would in a species with a shorter life expectancy.

The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. In many contexts, potato refers to the edible tuber, but it can also refer to the plant itself. Common or slang terms include tater, tattie and spud. Potatoes were introduced to Europe in the second half of the 16th century by the Spanish. Today they are a staple food in many parts of the world and an integral part of much of the world's food supply. As of 2014, potatoes were the world's fourth-largest food crop after maize (corn), wheat, and rice.
Wild potato species can be found throughout the Americas, from the United States to southern Chile. The potato was originally believed to have been domesticated independently in multiple locations, but later genetic testing of the wide variety of cultivars and wild species traced a single origin for potatoes. In the area of present-day southern Peru and extreme northwestern Bolivia, from a species in the Solanum brevicaule complex, potatoes were domesticated approximately 7,000–10,000 years ago. In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated.
Following millennia of selective breeding, there are now over 1,000 different types of potatoes. Over 99% of presently cultivated potatoes worldwide descended from varieties that originated in the lowlands of south-central Chile, which have displaced formerly popular varieties from the Andes.
The importance of the potato as a food source and culinary ingredient varies by region and is still changing. It remains an essential crop in Europe, especially eastern and central Europe, where per capita production is still the highest in the world, while the most rapid expansion in production over the past few decades has occurred in southern and eastern Asia, with China and India leading the world in overall production as of 2014.
Being a nightshade similar to tomatoes, the vegetative and fruiting parts of the potato contain the toxin solanine and are not fit for human consumption. Normal potato tubers that have been grown and stored properly produce glycoalkaloids in amounts small enough to be negligible to human health, but if green sections of the plant (namely sprouts and skins) are exposed to light, the tuber can accumulate a high enough concentration of glycoalkaloids to affect human health.
ETYMOLOGY
The English word potato comes from Spanish patata (the name used in Spain). The Spanish Royal Academy says the Spanish word is a hybrid of the Taíno batata (sweet potato) and the Quechua papa (potato). The name originally referred to the sweet potato although the two plants are not closely related. The 16th-century English herbalist John Gerard referred to sweet potatoes as "common potatoes", and used the terms "bastard potatoes" and "Virginia potatoes" for the species we now call "potato". In many of the chronicles detailing agriculture and plants, no distinction is made between the two. Potatoes are occasionally referred to as "Irish potatoes" or "white potatoes" in the United States, to distinguish them from sweet potatoes.
The name spud for a small potato comes from the digging of soil (or a hole) prior to the planting of potatoes. The word has an unknown origin and was originally (c. 1440) used as a term for a short knife or dagger, probably related to the Latin "spad-" a word root meaning "sword"; cf. Spanish "espada", English "spade" and "spadroon". It subsequently transferred over to a variety of digging tools. Around 1845, the name transferred to the tuber itself, the first record of this usage being in New Zealand English. The origin of the word "spud" has erroneously been attributed to an 18th-century activist group dedicated to keeping the potato out of Britain, calling itself The Society for the Prevention of Unwholesome Diet (S.P.U.D.). It was Mario Pei's 1949 The Story of Language that can be blamed for the word's false origin. Pei writes, "the potato, for its part, was in disrepute some centuries ago. Some Englishmen who did not fancy potatoes formed a Society for the Prevention of Unwholesome Diet. The initials of the main words in this title gave rise to spud." Like most other pre-20th century acronymic origins, this is false, and there is no evidence that a Society for the Prevention of Unwholesome Diet ever existed.
CHARACTERISTICS
Potato plants are herbaceous perennials that grow about 60 cm high, depending on variety, with the leaves dying back after flowering, fruiting and tuber formation. They bear white, pink, red, blue, or purple flowers with yellow stamens. In general, the tubers of varieties with white flowers have white skins, while those of varieties with colored flowers tend to have pinkish skins. Potatoes are mostly cross-pollinated by insects such as bumblebees, which carry pollen from other potato plants, though a substantial amount of self-fertilizing occurs as well. Tubers form in response to decreasing day length, although this tendency has been minimized in commercial varieties.
After flowering, potato plants produce small green fruits that resemble green cherry tomatoes, each containing about 300 seeds. Like all parts of the plant except the tubers, the fruit contain the toxic alkaloid solanine and are therefore unsuitable for consumption. All new potato varieties are grown from seeds, also called "true potato seed", "TPS" or "botanical seed" to distinguish it from seed tubers. New varieties grown from seed can be propagated vegetatively by planting tubers, pieces of tubers cut to include at least one or two eyes, or cuttings, a practice used in greenhouses for the production of healthy seed tubers. Plants propagated from tubers are clones of the parent, whereas those propagated from seed produce a range of different varieties.
GENETICS
There are about 5,000 potato varieties worldwide. Three thousand of them are found in the Andes alone, mainly in Peru, Bolivia, Ecuador, Chile, and Colombia. They belong to eight or nine species, depending on the taxonomic school. Apart from the 5,000 cultivated varieties, there are about 200 wild species and subspecies, many of which can be cross-bred with cultivated varieties. Cross-breeding has been done repeatedly to transfer resistances to certain pests and diseases from the gene pool of wild species to the gene pool of cultivated potato species. Genetically modified varieties have met public resistance in the United States and in the European UnionThe major species grown worldwide is Solanum tuberosum (a tetraploid with 48 chromosomes), and modern varieties of this species are the most widely cultivated. There are also four diploid species (with 24 chromosomes): S. stenotomum, S. phureja, S. goniocalyx, and S. ajanhuiri. There are two triploid species (with 36 chromosomes): S. chaucha and S. juzepczukii. There is one pentaploid cultivated species (with 60 chromosomes): S. curtilobum. There are two major subspecies of Solanum tuberosum: andigena, or Andean; and tuberosum, or Chilean. The Andean potato is adapted to the short-day conditions prevalent in the mountainous equatorial and tropical regions where it originated; the Chilean potato, however, native to the Chiloé Archipelago, is adapted to the long-day conditions prevalent in the higher latitude region of southern Chile.
The International Potato Center, based in Lima, Peru, holds an ISO-accredited collection of potato germplasm. The international Potato Genome Sequencing Consortium announced in 2009 that they had achieved a draft sequence of the potato genome. The potato genome contains 12 chromosomes and 860 million base pairs, making it a medium-sized plant genome. More than 99 percent of all current varieties of potatoes currently grown are direct descendants of a subspecies that once grew in the lowlands of south-central Chile. Nonetheless, genetic testing of the wide variety of cultivars and wild species affirms that all potato subspecies derive from a single origin in the area of present-day southern Peru and extreme Northwestern Bolivia (from a species in the Solanum brevicaule complex). The wild Crop Wild Relatives Prebreeding project encourages the use of wild relatives in breeding programs. Enriching and preserving the gene bank collection to make potatoes adaptive to diverse environmental conditions is seen as a pressing issue due to climate change.
Most modern potatoes grown in North America arrived through European settlement and not independently from the South American sources, although at least one wild potato species, Solanum fendleri, naturally ranges from Peru into Texas, where it is used in breeding for resistance to a nematode species that attacks cultivated potatoes. A secondary center of genetic variability of the potato is Mexico, where important wild species that have been used extensively in modern breeding are found, such as the hexaploid Solanum demissum, as a source of resistance to the devastating late blight disease. Another relative native to this region, Solanum bulbocastanum, has been used to genetically engineer the potato to resist potato blight.
Potatoes yield abundantly with little effort, and adapt readily to diverse climates as long as the climate is cool and moist enough for the plants to gather sufficient water from the soil to form the starchy tubers. Potatoes do not keep very well in storage and are vulnerable to moulds that feed on the stored tubers and quickly turn them rotten, whereas crops such as grain can be stored for several years with a low risk of rot. The yield of Calories per acre (about 9.2 million) is higher than that of maize (7.5 million), rice (7.4 million), wheat (3 million), or soybean (2.8 million).
VARIETIES
There are close to 4,000 varieties of potato including common commercial varieties, each of which has specific agricultural or culinary attributes. Around 80 varieties are commercially available in the UK. In general, varieties are categorized into a few main groups based on common characteristics, such as russet potatoes (rough brown skin), red potatoes, white potatoes, yellow potatoes (also called Yukon potatoes) and purple potatoes.
For culinary purposes, varieties are often differentiated by their waxiness: floury or mealy baking potatoes have more starch (20–22%) than waxy boiling potatoes (16–18%). The distinction may also arise from variation in the comparative ratio of two different potato starch compounds: amylose and amylopectin. Amylose, a long-chain molecule, diffuses from the starch granule when cooked in water, and lends itself to dishes where the potato is mashed. Varieties that contain a slightly higher amylopectin content, which is a highly branched molecule, help the potato retain its shape after being boiled in water. Potatoes that are good for making potato chips or potato crisps are sometimes called "chipping potatoes", which means they meet the basic requirements of similar varietal characteristics, being firm, fairly clean, and fairly well-shaped.
The European Cultivated Potato Database (ECPD) is an online collaborative database of potato variety descriptions that is updated and maintained by the Scottish Agricultural Science Agency within the framework of the European Cooperative Programme for Crop Genetic Resources Networks (ECP/GR)—which is run by the International Plant Genetic Resources Institute (IPGRI).
PIGMENTATION
Dozens of potato cultivars have been selectively bred specifically for their skin or, more commonly, flesh color, including gold, red, and blue varieties that contain varying amounts of phytochemicals, including carotenoids for gold/yellow or polyphenols for red or blue cultivars. Carotenoid compounds include provitamin A alpha-carotene and beta-carotene, which are converted to the essential nutrient, vitamin A, during digestion. Anthocyanins mainly responsible for red or blue pigmentation in potato cultivars do not have nutritional significance, but are used for visual variety and consumer appeal. Recently, as of 2010, potatoes have also been bioengineered specifically for these pigmentation traits.
GENETICALLY ENGINEERED POTATOES
Genetic research has produced several genetically modified varieties. 'New Leaf', owned by Monsanto Company, incorporates genes from Bacillus thuringiensis, which confers resistance to the Colorado potato beetle; 'New Leaf Plus' and 'New Leaf Y', approved by US regulatory agencies during the 1990s, also include resistance to viruses. McDonald's, Burger King, Frito-Lay, and Procter & Gamble announced they would not use genetically modified potatoes, and Monsanto published its intent to discontinue the line in March 2001.
Waxy potato varieties produce two main kinds of potato starch, amylose and amylopectin, the latter of which is most industrially useful. BASF developed the Amflora potato, which was modified to express antisense RNA to inactivate the gene for granule bound starch synthase, an enzyme which catalyzes the formation of amylose. Amflora potatoes therefore produce starch consisting almost entirely of amylopectin, and are thus more useful for the starch industry. In 2010, the European Commission cleared the way for 'Amflora' to be grown in the European Union for industrial purposes only—not for food. Nevertheless, under EU rules, individual countries have the right to decide whether they will allow this potato to be grown on their territory. Commercial planting of 'Amflora' was expected in the Czech Republic and Germany in the spring of 2010, and Sweden and the Netherlands in subsequent years. Another GM potato variety developed by BASF is 'Fortuna' which was made resistant to late blight by adding two resistance genes, blb1 and blb2, which originate from the Mexican wild potato Solanum bulbocastanum. In October 2011 BASF requested cultivation and marketing approval as a feed and food from the EFSA. In 2012, GMO development in Europe was stopped by BASF.
In November 2014, the USDA approved a genetically modified potato developed by J.R. Simplot Company, which contains genetic modifications that prevent bruising and produce less acrylamide when fried than conventional potatoes; the modifications do not cause new proteins to be made, but rather prevent proteins from being made via RNA interference.
HISTORY
The potato was first domesticated in the region of modern-day southern Peru and extreme northwestern Bolivia between 8000 and 5000 BC. It has since spread around the world and become a staple crop in many countries.
The earliest archaeologically verified potato tuber remains have been found at the coastal site of Ancon (central Peru), dating to 2500 BC. The most widely cultivated variety, Solanum tuberosum tuberosum, is indigenous to the Chiloé Archipelago, and has been cultivated by the local indigenous people since before the Spanish conquest.
According to conservative estimates, the introduction of the potato was responsible for a quarter of the growth in Old World population and urbanization between 1700 and 1900. In the Altiplano, potatoes provided the principal energy source for the Inca civilization, its predecessors, and its Spanish successor. Following the Spanish conquest of the Inca Empire, the Spanish introduced the potato to Europe in the second half of the 16th century, part of the Columbian exchange. The staple was subsequently conveyed by European mariners to territories and ports throughout the world. The potato was slow to be adopted by European farmers, but soon enough it became an important food staple and field crop that played a major role in the European 19th century population boom. However, lack of genetic diversity, due to the very limited number of varieties initially introduced, left the crop vulnerable to disease. In 1845, a plant disease known as late blight, caused by the fungus-like oomycete Phytophthora infestans, spread rapidly through the poorer communities of western Ireland as well as parts of the Scottish Highlands, resulting in the crop failures that led to the Great Irish Famine. Thousands of varieties still persist in the Andes however, where over 100 cultivars might be found in a single valley, and a dozen or more might be maintained by a single agricultural household.
PRODUCTION
In 2016, world production of potatoes was 377 million tonnes, led by China with over 26% of the world total (see table). Other major producers were India, Russia, Ukraine and the United States. It remains an essential crop in Europe (especially eastern and central Europe), where per capita production is still the highest in the world, but the most rapid expansion over the past few decades has occurred in southern and eastern Asia.
NUTRITION
A raw potato is 79% water, 17% carbohydrates (88% is starch), 2% protein, and contains negligible fat (see table). In an amount measuring 100 grams, raw potato provides 322 kilojoules (77 kilocalories) of energy and is a rich source of vitamin B6 and vitamin C (23% and 24% of the Daily Value, respectively), with no other vitamins or minerals in significant amount (see table). The potato is rarely eaten raw because raw potato starch is poorly digested by humans. When a potato is baked, its contents of vitamin B6 and vitamin C decline notably, while there is little significant change in the amount of other nutrients.
Potatoes are often broadly classified as having a high glycemic index (GI) and so are often excluded from the diets of individuals trying to follow a low-GI diet. The GI of potatoes can vary considerably depending on the cultivar or cultivar category (such as "red", russet, "white", or King Edward), growing conditions and storage, preparation methods (by cooking method, whether it is eaten hot or cold, whether it is mashed or cubed or consumed whole), and accompanying foods consumed (especially the addition of various high-fat or high-protein toppings). In particular, consuming reheated or cooled potatoes that were previously cooked may yield a lower GI effect.
In the UK, potatoes are not considered by the National Health Service (NHS) as counting or contributing towards the recommended daily five portions of fruit and vegetables, the 5-A-Day program.
COMPARISON TO OTHER STAPLE FOODS
This table shows the nutrient content of potatoes next to other major staple foods, each one measured in its respective raw state, even though staple foods are not commonly eaten raw and are usually sprouted or cooked before eating. In sprouted and cooked form, the relative nutritional and anti-nutritional contents of each of these grains (or other foods) may be different from the values in this table. Each nutrient (every row) has the highest number highlighted to show the staple food with the greatest amount in a 100-gram raw portion.
TOXICITY
Potatoes contain toxic compounds known as glycoalkaloids, of which the most prevalent are solanine and chaconine. Solanine is found in other plants in the same family, Solanaceae, which includes such plants as deadly nightshade (Atropa belladonna), henbane (Hyoscyamus niger) and tobacco (Nicotiana spp.), as well as the food plants eggplant and tomato. These compounds, which protect the potato plant from its predators, are generally concentrated in its leaves, flowers, sprouts, and fruits (in contrast to the tubers). In a summary of several studies, the glycoalkaloid content was highest in the flowers and sprouts and lowest in the tuber flesh. (The glycoalkaloid content was, in order from highest to lowest: flowers, sprouts, leaves, skin, roots, berries, peel [skin plus outer cortex of tuber flesh], stems, and tuber flesh.)
Exposure to light, physical damage, and age increase glycoalkaloid content within the tuber. Cooking at high temperatures—over 170 °C—partly destroys these compounds. The concentration of glycoalkaloids in wild potatoes is sufficient to produce toxic effects in humans. Glycoalkaloid poisoning may cause headaches, diarrhea, cramps, and, in severe cases, coma and death. However, poisoning from cultivated potato varieties is very rare. Light exposure causes greening from chlorophyll synthesis, giving a visual clue as to which areas of the tuber may have become more toxic. However, this does not provide a definitive guide, as greening and glycoalkaloid accumulation can occur independently of each other.
Different potato varieties contain different levels of glycoalkaloids. The Lenape variety was released in 1967 but was withdrawn in 1970 as it contained high levels of glycoalkaloids. Since then, breeders developing new varieties test for this, and sometimes have to discard an otherwise promising cultivar. Breeders try to keep glycoalkaloid levels below 200 mg/kg). However, when these commercial varieties turn green, they can still approach solanine concentrations of 1000 mg/kg. In normal potatoes, analysis has shown solanine levels may be as little as 3.5% of the breeders' maximum, with 7–187 mg/kg being found. While a normal potato tuber has 12–20 mg/kg of glycoalkaloid content, a green potato tuber contains 250–280 mg/kg and its skin has 1500–2200 mg/kg.
GROWTH AND CULTIVATION
SEED POTATOES
Potatoes are generally grown from seed potatoes, tubers specifically grown to be free from disease and to provide consistent and healthy plants. To be disease free, the areas where seed potatoes are grown are selected with care. In the US, this restricts production of seed potatoes to only 15 states out of all 50 states where potatoes are grown. These locations are selected for their cold, hard winters that kill pests and summers with long sunshine hours for optimum growth. In the UK, most seed potatoes originate in Scotland, in areas where westerly winds prevent aphid attack and thus prevent spread of potato virus pathogens.
PHASES OF GROWTH
Potato growth is divided into five phases. During the first phase, sprouts emerge from the seed potatoes and root growth begins. During the second, photosynthesis begins as the plant develops leaves and branches. In the third phase, stolons develop from lower leaf axils on the stem and grow downwards into the ground and on these stolons new tubers develop as swellings of the stolon. This phase is often, but not always, associated with flowering. Tuber formation halts when soil temperatures reach 27 °C; hence potatoes are considered a cool-season, or winter, crop. Tuber bulking occurs during the fourth phase, when the plant begins investing the majority of its resources in its newly formed tubers. At this phase, several factors are critical to a good yield: optimal soil moisture and temperature, soil nutrient availability and balance, and resistance to pest attacks. The fifth and final phase is the maturation of the tubers: the plant canopy dies back, the tuber skins harden, and the sugars in the tubers convert to starches.
CHALLENGES
New tubers may start growing at the surface of the soil. Since exposure to light leads to an undesirable greening of the skins and the development of solanine as a protection from the sun's rays, growers cover surface tubers. Commercial growers cover them by piling additional soil around the base of the plant as it grows (called "hilling" up, or in British English "earthing up"). An alternative method, used by home gardeners and smaller-scale growers, involves covering the growing area with organic mulches such as straw or plastic sheets.
Correct potato husbandry can be an arduous task in some circumstances. Good ground preparation, harrowing, plowing, and rolling are always needed, along with a little grace from the weather and a good source of water. Three successive plowings, with associated harrowing and rolling, are desirable before planting. Eliminating all root-weeds is desirable in potato cultivation. In general, the potatoes themselves are grown from the eyes of another potato and not from seed. Home gardeners often plant a piece of potato with two or three eyes in a hill of mounded soil. Commercial growers plant potatoes as a row crop using seed tubers, young plants or microtubers and may mound the entire row. Seed potato crops are rogued in some countries to eliminate diseased plants or those of a different variety from the seed crop.
Potatoes are sensitive to heavy frosts, which damage them in the ground. Even cold weather makes potatoes more susceptible to bruising and possibly later rotting, which can quickly ruin a large stored crop.
PESTS
The historically significant Phytophthora infestans (late blight) remains an ongoing problem in Europe and the United States. Other potato diseases include Rhizoctonia, Sclerotinia, black leg, powdery mildew, powdery scab and leafroll virus.
Insects that commonly transmit potato diseases or damage the plants include the Colorado potato beetle, the potato tuber moth, the green peach aphid (Myzus persicae), the potato aphid, beet leafhoppers, thrips, and mites. The potato cyst nematode is a microscopic worm that thrives on the roots, thus causing the potato plants to wilt. Since its eggs can survive in the soil for several years, crop rotation is recommended.
During the crop year 2008, many of the certified organic potatoes produced in the United Kingdom and certified by the Soil Association as organic were sprayed with a copper pesticide to control potato blight (Phytophthora infestans). According to the Soil Association, the total copper that can be applied to organic land is 6 kg/ha/year.
According to an Environmental Working Group analysis of USDA and FDA pesticide residue tests performed from 2000 through 2008, 84% of the 2,216 tested potato samples contained detectable traces of at least one pesticide. A total of 36 unique pesticides were detected on potatoes over the 2,216 samples, though no individual sample contained more than 6 unique pesticide traces, and the average was 1.29 detectable unique pesticide traces per sample. The average quantity of all pesticide traces found in the 2,216 samples was 1.602 ppm. While this was a very low value of pesticide residue, it was the highest amongst the 50 vegetables analyzed.
HARVEST
At harvest time, gardeners usually dig up potatoes with a long-handled, three-prong "grape" (or graip), i.e., a spading fork, or a potato hook, which is similar to the graip but with tines at a 90° angle to the handle. In larger plots, the plow is the fastest implement for unearthing potatoes. Commercial harvesting is typically done with large potato harvesters, which scoop up the plant and surrounding earth. This is transported up an apron chain consisting of steel links several feet wide, which separates some of the dirt. The chain deposits into an area where further separation occurs. Different designs use different systems at this point. The most complex designs use vine choppers and shakers, along with a blower system to separate the potatoes from the plant. The result is then usually run past workers who continue to sort out plant material, stones, and rotten potatoes before the potatoes are continuously delivered to a wagon or truck. Further inspection and separation occurs when the potatoes are unloaded from the field vehicles and put into storage.
Immature potatoes may be sold as "creamer potatoes" and are particularly valued for taste. These are often harvested by the home gardener or farmer by "grabbling", i.e. pulling out the young tubers by hand while leaving the plant in place. A creamer potato is a variety of potato harvested before it matures to keep it small and tender. It is generally either a Yukon Gold potato or a red potato, called gold creamers or red creamers respectively, and measures approximately 2.5 cm in diameter. The skin of creamer potatoes is waxy and high in moisture content, and the flesh contains a lower level of starch than other potatoes. Like potatoes in general, they can be prepared by boiling, baking, frying, and roasting. Slightly older than creamer potatoes are "new potatoes", which are also prized for their taste and texture and often come from the same varieties.
Potatoes are usually cured after harvest to improve skin-set. Skin-set is the process by which the skin of the potato becomes resistant to skinning damage. Potato tubers may be susceptible to skinning at harvest and suffer skinning damage during harvest and handling operations. Curing allows the skin to fully set and any wounds to heal. Wound-healing prevents infection and water-loss from the tubers during storage. Curing is normally done at relatively warm temperatures 10 to 16 °C with high humidity and good gas-exchange if at all possible.
STORAGE
Storage facilities need to be carefully designed to keep the potatoes alive and slow the natural process of decomposition, which involves the breakdown of starch. It is crucial that the storage area is dark, ventilated well and, for long-term storage, maintained at temperatures near 4 °C. For short-term storage, temperatures of about 7 to 10 °C are preferred.
On the other hand, temperatures below 4 °C convert the starch in potatoes into sugar, which alters their taste and cooking qualities and leads to higher acrylamide levels in the cooked product, especially in deep-fried dishes. The discovery of acrylamides in starchy foods in 2002 has led to international health concerns. They are believed to be probable carcinogens and their occurrence in cooked foods is being studied for potentially influencing health problems.
Under optimum conditions in commercial warehouses, potatoes can be stored for up to 10–12 months. The commercial storage and retrieval of potatoes involves several phases: first drying surface moisture; wound healing at 85% to 95% relative humidity and temperatures below 25 °C; a staged cooling phase; a holding phase; and a reconditioning phase, during which the tubers are slowly warmed. Mechanical ventilation is used at various points during the process to prevent condensation and the accumulation of carbon dioxide.
When stored in homes unrefrigerated, the shelf life is usually a few weeks.
If potatoes develop green areas or start to sprout, trimming or peeling those green-colored parts is inadequate to remove copresent toxins, and such potatoes are no longer edible.
YIELD
The world dedicated 18.6 million ha in 2010 for potato cultivation. The average world farm yield for potato was 17.4 tonnes per hectare, in 2010. Potato farms in the United States were the most productive in 2010, with a nationwide average of 44.3 tonnes per hectare. United Kingdom was a close second.
New Zealand farmers have demonstrated some of the best commercial yields in the world, ranging between 60 and 80 tonnes per hectare, some reporting yields of 88 tonnes potatoes per hectare.
There is a big gap among various countries between high and low yields, even with the same variety of potato. Average potato yields in developed economies ranges between 38–44 tonnes per hectare. China and India accounted for over a third of world's production in 2010, and had yields of 14.7 and 19.9 tonnes per hectare respectively. The yield gap between farms in developing economies and developed economies represents an opportunity loss of over 400 million tonnes of potato, or an amount greater than 2010 world potato production. Potato crop yields are determined by factors such as the crop breed, seed age and quality, crop management practices and the plant environment. Improvements in one or more of these yield determinants, and a closure of the yield gap, can be a major boost to food supply and farmer incomes in the developing world.
USES
Potatoes are prepared in many ways: skin-on or peeled, whole or cut up, with seasonings or without. The only requirement involves cooking to swell the starch granules. Most potato dishes are served hot but some are first cooked, then served cold, notably potato salad and potato chips (crisps). Common dishes are: mashed potatoes, which are first boiled (usually peeled), and then mashed with milk or yogurt and butter; whole baked potatoes; boiled or steamed potatoes; French-fried potatoes or chips; cut into cubes and roasted; scalloped, diced, or sliced and fried (home fries); grated into small thin strips and fried (hash browns); grated and formed into dumplings, Rösti or potato pancakes. Unlike many foods, potatoes can also be easily cooked in a microwave oven and still retain nearly all of their nutritional value, provided they are covered in ventilated plastic wrap to prevent moisture from escaping; this method produces a meal very similar to a steamed potato, while retaining the appearance of a conventionally baked potato. Potato chunks also commonly appear as a stew ingredient. Potatoes are boiled between 10 and 25 minutes, depending on size and type, to become soft.
OTHER THAN FOR EATING
Potatoes are also used for purposes other than eating by humans, for example:
Potatoes are used to brew alcoholic beverages such as vodka, poitín, or akvavit.
They are also used as fodder for livestock. Livestock-grade potatoes, considered too small and/or blemished to sell or market for human use but suitable for fodder use, have been called chats in some dialects. They may be stored in bins until use; they are sometimes ensiled. Some farmers prefer to steam them rather than feed them raw and are equipped to do so efficiently.
Potato starch is used in the food industry as a thickener and binder for soups and sauces, in the textile industry as an adhesive, and for the manufacturing of papers and boards.
Maine companies are exploring the possibilities of using waste potatoes to obtain polylactic acid for use in plastic products; other research projects seek ways to use the starch as a base for biodegradable packaging.
Potato skins, along with honey, are a folk remedy for burns in India. Burn centres in India have experimented with the use of the thin outer skin layer to protect burns while healing.
Potatoes (mainly Russets) are commonly used in plant research. The consistent parenchyma tissue, the clonal nature of the plant and the low metabolic activity provide a very nice "model tissue" for experimentation. Wound-response studies are often done on potato tuber tissue, as are electron transport experiments. In this respect, potato tuber tissue is similar to Drosophila melanogaster, Caenorhabditis elegans and Escherichia coli: they are all "standard" research organisms.
Potatoes have been delivered with personalized messages as a novelty. Potato delivery services include Potato Parcel and Mail A Spud.
WIKIPEDIA
The potato is a starchy, tuberous crop from the perennial nightshade Solanum tuberosum. In many contexts, potato refers to the edible tuber, but it can also refer to the plant itself. Common or slang terms include tater, tattie and spud. Potatoes were introduced to Europe in the second half of the 16th century by the Spanish. Today they are a staple food in many parts of the world and an integral part of much of the world's food supply. As of 2014, potatoes were the world's fourth-largest food crop after maize (corn), wheat, and rice.
Wild potato species can be found throughout the Americas, from the United States to southern Chile. The potato was originally believed to have been domesticated independently in multiple locations, but later genetic testing of the wide variety of cultivars and wild species traced a single origin for potatoes. In the area of present-day southern Peru and extreme northwestern Bolivia, from a species in the Solanum brevicaule complex, potatoes were domesticated approximately 7,000–10,000 years ago. In the Andes region of South America, where the species is indigenous, some close relatives of the potato are cultivated.
Following millennia of selective breeding, there are now over 1,000 different types of potatoes. Over 99% of presently cultivated potatoes worldwide descended from varieties that originated in the lowlands of south-central Chile, which have displaced formerly popular varieties from the Andes.
The importance of the potato as a food source and culinary ingredient varies by region and is still changing. It remains an essential crop in Europe, especially eastern and central Europe, where per capita production is still the highest in the world, while the most rapid expansion in production over the past few decades has occurred in southern and eastern Asia, with China and India leading the world in overall production as of 2014.
Being a nightshade similar to tomatoes, the vegetative and fruiting parts of the potato contain the toxin solanine and are not fit for human consumption. Normal potato tubers that have been grown and stored properly produce glycoalkaloids in amounts small enough to be negligible to human health, but if green sections of the plant (namely sprouts and skins) are exposed to light, the tuber can accumulate a high enough concentration of glycoalkaloids to affect human health.
ETYMOLOGY
The English word potato comes from Spanish patata (the name used in Spain). The Spanish Royal Academy says the Spanish word is a hybrid of the Taíno batata (sweet potato) and the Quechua papa (potato). The name originally referred to the sweet potato although the two plants are not closely related. The 16th-century English herbalist John Gerard referred to sweet potatoes as "common potatoes", and used the terms "bastard potatoes" and "Virginia potatoes" for the species we now call "potato". In many of the chronicles detailing agriculture and plants, no distinction is made between the two. Potatoes are occasionally referred to as "Irish potatoes" or "white potatoes" in the United States, to distinguish them from sweet potatoes.
The name spud for a small potato comes from the digging of soil (or a hole) prior to the planting of potatoes. The word has an unknown origin and was originally (c. 1440) used as a term for a short knife or dagger, probably related to the Latin "spad-" a word root meaning "sword"; cf. Spanish "espada", English "spade" and "spadroon". It subsequently transferred over to a variety of digging tools. Around 1845, the name transferred to the tuber itself, the first record of this usage being in New Zealand English. The origin of the word "spud" has erroneously been attributed to an 18th-century activist group dedicated to keeping the potato out of Britain, calling itself The Society for the Prevention of Unwholesome Diet (S.P.U.D.). It was Mario Pei's 1949 The Story of Language that can be blamed for the word's false origin. Pei writes, "the potato, for its part, was in disrepute some centuries ago. Some Englishmen who did not fancy potatoes formed a Society for the Prevention of Unwholesome Diet. The initials of the main words in this title gave rise to spud." Like most other pre-20th century acronymic origins, this is false, and there is no evidence that a Society for the Prevention of Unwholesome Diet ever existed.
CHARACTERISTICS
Potato plants are herbaceous perennials that grow about 60 cm high, depending on variety, with the leaves dying back after flowering, fruiting and tuber formation. They bear white, pink, red, blue, or purple flowers with yellow stamens. In general, the tubers of varieties with white flowers have white skins, while those of varieties with colored flowers tend to have pinkish skins. Potatoes are mostly cross-pollinated by insects such as bumblebees, which carry pollen from other potato plants, though a substantial amount of self-fertilizing occurs as well. Tubers form in response to decreasing day length, although this tendency has been minimized in commercial varieties.
After flowering, potato plants produce small green fruits that resemble green cherry tomatoes, each containing about 300 seeds. Like all parts of the plant except the tubers, the fruit contain the toxic alkaloid solanine and are therefore unsuitable for consumption. All new potato varieties are grown from seeds, also called "true potato seed", "TPS" or "botanical seed" to distinguish it from seed tubers. New varieties grown from seed can be propagated vegetatively by planting tubers, pieces of tubers cut to include at least one or two eyes, or cuttings, a practice used in greenhouses for the production of healthy seed tubers. Plants propagated from tubers are clones of the parent, whereas those propagated from seed produce a range of different varieties.
GENETICS
There are about 5,000 potato varieties worldwide. Three thousand of them are found in the Andes alone, mainly in Peru, Bolivia, Ecuador, Chile, and Colombia. They belong to eight or nine species, depending on the taxonomic school. Apart from the 5,000 cultivated varieties, there are about 200 wild species and subspecies, many of which can be cross-bred with cultivated varieties. Cross-breeding has been done repeatedly to transfer resistances to certain pests and diseases from the gene pool of wild species to the gene pool of cultivated potato species. Genetically modified varieties have met public resistance in the United States and in the European UnionThe major species grown worldwide is Solanum tuberosum (a tetraploid with 48 chromosomes), and modern varieties of this species are the most widely cultivated. There are also four diploid species (with 24 chromosomes): S. stenotomum, S. phureja, S. goniocalyx, and S. ajanhuiri. There are two triploid species (with 36 chromosomes): S. chaucha and S. juzepczukii. There is one pentaploid cultivated species (with 60 chromosomes): S. curtilobum. There are two major subspecies of Solanum tuberosum: andigena, or Andean; and tuberosum, or Chilean. The Andean potato is adapted to the short-day conditions prevalent in the mountainous equatorial and tropical regions where it originated; the Chilean potato, however, native to the Chiloé Archipelago, is adapted to the long-day conditions prevalent in the higher latitude region of southern Chile.
The International Potato Center, based in Lima, Peru, holds an ISO-accredited collection of potato germplasm. The international Potato Genome Sequencing Consortium announced in 2009 that they had achieved a draft sequence of the potato genome. The potato genome contains 12 chromosomes and 860 million base pairs, making it a medium-sized plant genome. More than 99 percent of all current varieties of potatoes currently grown are direct descendants of a subspecies that once grew in the lowlands of south-central Chile. Nonetheless, genetic testing of the wide variety of cultivars and wild species affirms that all potato subspecies derive from a single origin in the area of present-day southern Peru and extreme Northwestern Bolivia (from a species in the Solanum brevicaule complex). The wild Crop Wild Relatives Prebreeding project encourages the use of wild relatives in breeding programs. Enriching and preserving the gene bank collection to make potatoes adaptive to diverse environmental conditions is seen as a pressing issue due to climate change.
Most modern potatoes grown in North America arrived through European settlement and not independently from the South American sources, although at least one wild potato species, Solanum fendleri, naturally ranges from Peru into Texas, where it is used in breeding for resistance to a nematode species that attacks cultivated potatoes. A secondary center of genetic variability of the potato is Mexico, where important wild species that have been used extensively in modern breeding are found, such as the hexaploid Solanum demissum, as a source of resistance to the devastating late blight disease. Another relative native to this region, Solanum bulbocastanum, has been used to genetically engineer the potato to resist potato blight.
Potatoes yield abundantly with little effort, and adapt readily to diverse climates as long as the climate is cool and moist enough for the plants to gather sufficient water from the soil to form the starchy tubers. Potatoes do not keep very well in storage and are vulnerable to moulds that feed on the stored tubers and quickly turn them rotten, whereas crops such as grain can be stored for several years with a low risk of rot. The yield of Calories per acre (about 9.2 million) is higher than that of maize (7.5 million), rice (7.4 million), wheat (3 million), or soybean (2.8 million).
VARIETIES
There are close to 4,000 varieties of potato including common commercial varieties, each of which has specific agricultural or culinary attributes. Around 80 varieties are commercially available in the UK. In general, varieties are categorized into a few main groups based on common characteristics, such as russet potatoes (rough brown skin), red potatoes, white potatoes, yellow potatoes (also called Yukon potatoes) and purple potatoes.
For culinary purposes, varieties are often differentiated by their waxiness: floury or mealy baking potatoes have more starch (20–22%) than waxy boiling potatoes (16–18%). The distinction may also arise from variation in the comparative ratio of two different potato starch compounds: amylose and amylopectin. Amylose, a long-chain molecule, diffuses from the starch granule when cooked in water, and lends itself to dishes where the potato is mashed. Varieties that contain a slightly higher amylopectin content, which is a highly branched molecule, help the potato retain its shape after being boiled in water. Potatoes that are good for making potato chips or potato crisps are sometimes called "chipping potatoes", which means they meet the basic requirements of similar varietal characteristics, being firm, fairly clean, and fairly well-shaped.
The European Cultivated Potato Database (ECPD) is an online collaborative database of potato variety descriptions that is updated and maintained by the Scottish Agricultural Science Agency within the framework of the European Cooperative Programme for Crop Genetic Resources Networks (ECP/GR)—which is run by the International Plant Genetic Resources Institute (IPGRI).
PIGMENTATION
Dozens of potato cultivars have been selectively bred specifically for their skin or, more commonly, flesh color, including gold, red, and blue varieties that contain varying amounts of phytochemicals, including carotenoids for gold/yellow or polyphenols for red or blue cultivars. Carotenoid compounds include provitamin A alpha-carotene and beta-carotene, which are converted to the essential nutrient, vitamin A, during digestion. Anthocyanins mainly responsible for red or blue pigmentation in potato cultivars do not have nutritional significance, but are used for visual variety and consumer appeal. Recently, as of 2010, potatoes have also been bioengineered specifically for these pigmentation traits.
GENETICALLY ENGINEERED POTATOES
Genetic research has produced several genetically modified varieties. 'New Leaf', owned by Monsanto Company, incorporates genes from Bacillus thuringiensis, which confers resistance to the Colorado potato beetle; 'New Leaf Plus' and 'New Leaf Y', approved by US regulatory agencies during the 1990s, also include resistance to viruses. McDonald's, Burger King, Frito-Lay, and Procter & Gamble announced they would not use genetically modified potatoes, and Monsanto published its intent to discontinue the line in March 2001.
Waxy potato varieties produce two main kinds of potato starch, amylose and amylopectin, the latter of which is most industrially useful. BASF developed the Amflora potato, which was modified to express antisense RNA to inactivate the gene for granule bound starch synthase, an enzyme which catalyzes the formation of amylose. Amflora potatoes therefore produce starch consisting almost entirely of amylopectin, and are thus more useful for the starch industry. In 2010, the European Commission cleared the way for 'Amflora' to be grown in the European Union for industrial purposes only—not for food. Nevertheless, under EU rules, individual countries have the right to decide whether they will allow this potato to be grown on their territory. Commercial planting of 'Amflora' was expected in the Czech Republic and Germany in the spring of 2010, and Sweden and the Netherlands in subsequent years. Another GM potato variety developed by BASF is 'Fortuna' which was made resistant to late blight by adding two resistance genes, blb1 and blb2, which originate from the Mexican wild potato Solanum bulbocastanum. In October 2011 BASF requested cultivation and marketing approval as a feed and food from the EFSA. In 2012, GMO development in Europe was stopped by BASF.
In November 2014, the USDA approved a genetically modified potato developed by J.R. Simplot Company, which contains genetic modifications that prevent bruising and produce less acrylamide when fried than conventional potatoes; the modifications do not cause new proteins to be made, but rather prevent proteins from being made via RNA interference.
HISTORY
The potato was first domesticated in the region of modern-day southern Peru and extreme northwestern Bolivia between 8000 and 5000 BC. It has since spread around the world and become a staple crop in many countries.
The earliest archaeologically verified potato tuber remains have been found at the coastal site of Ancon (central Peru), dating to 2500 BC. The most widely cultivated variety, Solanum tuberosum tuberosum, is indigenous to the Chiloé Archipelago, and has been cultivated by the local indigenous people since before the Spanish conquest.
According to conservative estimates, the introduction of the potato was responsible for a quarter of the growth in Old World population and urbanization between 1700 and 1900. In the Altiplano, potatoes provided the principal energy source for the Inca civilization, its predecessors, and its Spanish successor. Following the Spanish conquest of the Inca Empire, the Spanish introduced the potato to Europe in the second half of the 16th century, part of the Columbian exchange. The staple was subsequently conveyed by European mariners to territories and ports throughout the world. The potato was slow to be adopted by European farmers, but soon enough it became an important food staple and field crop that played a major role in the European 19th century population boom. However, lack of genetic diversity, due to the very limited number of varieties initially introduced, left the crop vulnerable to disease. In 1845, a plant disease known as late blight, caused by the fungus-like oomycete Phytophthora infestans, spread rapidly through the poorer communities of western Ireland as well as parts of the Scottish Highlands, resulting in the crop failures that led to the Great Irish Famine. Thousands of varieties still persist in the Andes however, where over 100 cultivars might be found in a single valley, and a dozen or more might be maintained by a single agricultural household.
PRODUCTION
In 2016, world production of potatoes was 377 million tonnes, led by China with over 26% of the world total (see table). Other major producers were India, Russia, Ukraine and the United States. It remains an essential crop in Europe (especially eastern and central Europe), where per capita production is still the highest in the world, but the most rapid expansion over the past few decades has occurred in southern and eastern Asia.
NUTRITION
A raw potato is 79% water, 17% carbohydrates (88% is starch), 2% protein, and contains negligible fat (see table). In an amount measuring 100 grams, raw potato provides 322 kilojoules (77 kilocalories) of energy and is a rich source of vitamin B6 and vitamin C (23% and 24% of the Daily Value, respectively), with no other vitamins or minerals in significant amount (see table). The potato is rarely eaten raw because raw potato starch is poorly digested by humans. When a potato is baked, its contents of vitamin B6 and vitamin C decline notably, while there is little significant change in the amount of other nutrients.
Potatoes are often broadly classified as having a high glycemic index (GI) and so are often excluded from the diets of individuals trying to follow a low-GI diet. The GI of potatoes can vary considerably depending on the cultivar or cultivar category (such as "red", russet, "white", or King Edward), growing conditions and storage, preparation methods (by cooking method, whether it is eaten hot or cold, whether it is mashed or cubed or consumed whole), and accompanying foods consumed (especially the addition of various high-fat or high-protein toppings). In particular, consuming reheated or cooled potatoes that were previously cooked may yield a lower GI effect.
In the UK, potatoes are not considered by the National Health Service (NHS) as counting or contributing towards the recommended daily five portions of fruit and vegetables, the 5-A-Day program.
COMPARISON TO OTHER STAPLE FOODS
This table shows the nutrient content of potatoes next to other major staple foods, each one measured in its respective raw state, even though staple foods are not commonly eaten raw and are usually sprouted or cooked before eating. In sprouted and cooked form, the relative nutritional and anti-nutritional contents of each of these grains (or other foods) may be different from the values in this table. Each nutrient (every row) has the highest number highlighted to show the staple food with the greatest amount in a 100-gram raw portion.
TOXICITY
Potatoes contain toxic compounds known as glycoalkaloids, of which the most prevalent are solanine and chaconine. Solanine is found in other plants in the same family, Solanaceae, which includes such plants as deadly nightshade (Atropa belladonna), henbane (Hyoscyamus niger) and tobacco (Nicotiana spp.), as well as the food plants eggplant and tomato. These compounds, which protect the potato plant from its predators, are generally concentrated in its leaves, flowers, sprouts, and fruits (in contrast to the tubers). In a summary of several studies, the glycoalkaloid content was highest in the flowers and sprouts and lowest in the tuber flesh. (The glycoalkaloid content was, in order from highest to lowest: flowers, sprouts, leaves, skin, roots, berries, peel [skin plus outer cortex of tuber flesh], stems, and tuber flesh.)
Exposure to light, physical damage, and age increase glycoalkaloid content within the tuber. Cooking at high temperatures—over 170 °C—partly destroys these compounds. The concentration of glycoalkaloids in wild potatoes is sufficient to produce toxic effects in humans. Glycoalkaloid poisoning may cause headaches, diarrhea, cramps, and, in severe cases, coma and death. However, poisoning from cultivated potato varieties is very rare. Light exposure causes greening from chlorophyll synthesis, giving a visual clue as to which areas of the tuber may have become more toxic. However, this does not provide a definitive guide, as greening and glycoalkaloid accumulation can occur independently of each other.
Different potato varieties contain different levels of glycoalkaloids. The Lenape variety was released in 1967 but was withdrawn in 1970 as it contained high levels of glycoalkaloids. Since then, breeders developing new varieties test for this, and sometimes have to discard an otherwise promising cultivar. Breeders try to keep glycoalkaloid levels below 200 mg/kg). However, when these commercial varieties turn green, they can still approach solanine concentrations of 1000 mg/kg. In normal potatoes, analysis has shown solanine levels may be as little as 3.5% of the breeders' maximum, with 7–187 mg/kg being found. While a normal potato tuber has 12–20 mg/kg of glycoalkaloid content, a green potato tuber contains 250–280 mg/kg and its skin has 1500–2200 mg/kg.
GROWTH AND CULTIVATION
SEED POTATOES
Potatoes are generally grown from seed potatoes, tubers specifically grown to be free from disease and to provide consistent and healthy plants. To be disease free, the areas where seed potatoes are grown are selected with care. In the US, this restricts production of seed potatoes to only 15 states out of all 50 states where potatoes are grown. These locations are selected for their cold, hard winters that kill pests and summers with long sunshine hours for optimum growth. In the UK, most seed potatoes originate in Scotland, in areas where westerly winds prevent aphid attack and thus prevent spread of potato virus pathogens.
PHASES OF GROWTH
Potato growth is divided into five phases. During the first phase, sprouts emerge from the seed potatoes and root growth begins. During the second, photosynthesis begins as the plant develops leaves and branches. In the third phase, stolons develop from lower leaf axils on the stem and grow downwards into the ground and on these stolons new tubers develop as swellings of the stolon. This phase is often, but not always, associated with flowering. Tuber formation halts when soil temperatures reach 27 °C; hence potatoes are considered a cool-season, or winter, crop. Tuber bulking occurs during the fourth phase, when the plant begins investing the majority of its resources in its newly formed tubers. At this phase, several factors are critical to a good yield: optimal soil moisture and temperature, soil nutrient availability and balance, and resistance to pest attacks. The fifth and final phase is the maturation of the tubers: the plant canopy dies back, the tuber skins harden, and the sugars in the tubers convert to starches.
CHALLENGES
New tubers may start growing at the surface of the soil. Since exposure to light leads to an undesirable greening of the skins and the development of solanine as a protection from the sun's rays, growers cover surface tubers. Commercial growers cover them by piling additional soil around the base of the plant as it grows (called "hilling" up, or in British English "earthing up"). An alternative method, used by home gardeners and smaller-scale growers, involves covering the growing area with organic mulches such as straw or plastic sheets.
Correct potato husbandry can be an arduous task in some circumstances. Good ground preparation, harrowing, plowing, and rolling are always needed, along with a little grace from the weather and a good source of water. Three successive plowings, with associated harrowing and rolling, are desirable before planting. Eliminating all root-weeds is desirable in potato cultivation. In general, the potatoes themselves are grown from the eyes of another potato and not from seed. Home gardeners often plant a piece of potato with two or three eyes in a hill of mounded soil. Commercial growers plant potatoes as a row crop using seed tubers, young plants or microtubers and may mound the entire row. Seed potato crops are rogued in some countries to eliminate diseased plants or those of a different variety from the seed crop.
Potatoes are sensitive to heavy frosts, which damage them in the ground. Even cold weather makes potatoes more susceptible to bruising and possibly later rotting, which can quickly ruin a large stored crop.
PESTS
The historically significant Phytophthora infestans (late blight) remains an ongoing problem in Europe and the United States. Other potato diseases include Rhizoctonia, Sclerotinia, black leg, powdery mildew, powdery scab and leafroll virus.
Insects that commonly transmit potato diseases or damage the plants include the Colorado potato beetle, the potato tuber moth, the green peach aphid (Myzus persicae), the potato aphid, beet leafhoppers, thrips, and mites. The potato cyst nematode is a microscopic worm that thrives on the roots, thus causing the potato plants to wilt. Since its eggs can survive in the soil for several years, crop rotation is recommended.
During the crop year 2008, many of the certified organic potatoes produced in the United Kingdom and certified by the Soil Association as organic were sprayed with a copper pesticide to control potato blight (Phytophthora infestans). According to the Soil Association, the total copper that can be applied to organic land is 6 kg/ha/year.
According to an Environmental Working Group analysis of USDA and FDA pesticide residue tests performed from 2000 through 2008, 84% of the 2,216 tested potato samples contained detectable traces of at least one pesticide. A total of 36 unique pesticides were detected on potatoes over the 2,216 samples, though no individual sample contained more than 6 unique pesticide traces, and the average was 1.29 detectable unique pesticide traces per sample. The average quantity of all pesticide traces found in the 2,216 samples was 1.602 ppm. While this was a very low value of pesticide residue, it was the highest amongst the 50 vegetables analyzed.
HARVEST
At harvest time, gardeners usually dig up potatoes with a long-handled, three-prong "grape" (or graip), i.e., a spading fork, or a potato hook, which is similar to the graip but with tines at a 90° angle to the handle. In larger plots, the plow is the fastest implement for unearthing potatoes. Commercial harvesting is typically done with large potato harvesters, which scoop up the plant and surrounding earth. This is transported up an apron chain consisting of steel links several feet wide, which separates some of the dirt. The chain deposits into an area where further separation occurs. Different designs use different systems at this point. The most complex designs use vine choppers and shakers, along with a blower system to separate the potatoes from the plant. The result is then usually run past workers who continue to sort out plant material, stones, and rotten potatoes before the potatoes are continuously delivered to a wagon or truck. Further inspection and separation occurs when the potatoes are unloaded from the field vehicles and put into storage.
Immature potatoes may be sold as "creamer potatoes" and are particularly valued for taste. These are often harvested by the home gardener or farmer by "grabbling", i.e. pulling out the young tubers by hand while leaving the plant in place. A creamer potato is a variety of potato harvested before it matures to keep it small and tender. It is generally either a Yukon Gold potato or a red potato, called gold creamers or red creamers respectively, and measures approximately 2.5 cm in diameter. The skin of creamer potatoes is waxy and high in moisture content, and the flesh contains a lower level of starch than other potatoes. Like potatoes in general, they can be prepared by boiling, baking, frying, and roasting. Slightly older than creamer potatoes are "new potatoes", which are also prized for their taste and texture and often come from the same varieties.
Potatoes are usually cured after harvest to improve skin-set. Skin-set is the process by which the skin of the potato becomes resistant to skinning damage. Potato tubers may be susceptible to skinning at harvest and suffer skinning damage during harvest and handling operations. Curing allows the skin to fully set and any wounds to heal. Wound-healing prevents infection and water-loss from the tubers during storage. Curing is normally done at relatively warm temperatures 10 to 16 °C with high humidity and good gas-exchange if at all possible.
STORAGE
Storage facilities need to be carefully designed to keep the potatoes alive and slow the natural process of decomposition, which involves the breakdown of starch. It is crucial that the storage area is dark, ventilated well and, for long-term storage, maintained at temperatures near 4 °C. For short-term storage, temperatures of about 7 to 10 °C are preferred.
On the other hand, temperatures below 4 °C convert the starch in potatoes into sugar, which alters their taste and cooking qualities and leads to higher acrylamide levels in the cooked product, especially in deep-fried dishes. The discovery of acrylamides in starchy foods in 2002 has led to international health concerns. They are believed to be probable carcinogens and their occurrence in cooked foods is being studied for potentially influencing health problems.
Under optimum conditions in commercial warehouses, potatoes can be stored for up to 10–12 months. The commercial storage and retrieval of potatoes involves several phases: first drying surface moisture; wound healing at 85% to 95% relative humidity and temperatures below 25 °C; a staged cooling phase; a holding phase; and a reconditioning phase, during which the tubers are slowly warmed. Mechanical ventilation is used at various points during the process to prevent condensation and the accumulation of carbon dioxide.
When stored in homes unrefrigerated, the shelf life is usually a few weeks.
If potatoes develop green areas or start to sprout, trimming or peeling those green-colored parts is inadequate to remove copresent toxins, and such potatoes are no longer edible.
YIELD
The world dedicated 18.6 million ha in 2010 for potato cultivation. The average world farm yield for potato was 17.4 tonnes per hectare, in 2010. Potato farms in the United States were the most productive in 2010, with a nationwide average of 44.3 tonnes per hectare. United Kingdom was a close second.
New Zealand farmers have demonstrated some of the best commercial yields in the world, ranging between 60 and 80 tonnes per hectare, some reporting yields of 88 tonnes potatoes per hectare.
There is a big gap among various countries between high and low yields, even with the same variety of potato. Average potato yields in developed economies ranges between 38–44 tonnes per hectare. China and India accounted for over a third of world's production in 2010, and had yields of 14.7 and 19.9 tonnes per hectare respectively. The yield gap between farms in developing economies and developed economies represents an opportunity loss of over 400 million tonnes of potato, or an amount greater than 2010 world potato production. Potato crop yields are determined by factors such as the crop breed, seed age and quality, crop management practices and the plant environment. Improvements in one or more of these yield determinants, and a closure of the yield gap, can be a major boost to food supply and farmer incomes in the developing world.
USES
Potatoes are prepared in many ways: skin-on or peeled, whole or cut up, with seasonings or without. The only requirement involves cooking to swell the starch granules. Most potato dishes are served hot but some are first cooked, then served cold, notably potato salad and potato chips (crisps). Common dishes are: mashed potatoes, which are first boiled (usually peeled), and then mashed with milk or yogurt and butter; whole baked potatoes; boiled or steamed potatoes; French-fried potatoes or chips; cut into cubes and roasted; scalloped, diced, or sliced and fried (home fries); grated into small thin strips and fried (hash browns); grated and formed into dumplings, Rösti or potato pancakes. Unlike many foods, potatoes can also be easily cooked in a microwave oven and still retain nearly all of their nutritional value, provided they are covered in ventilated plastic wrap to prevent moisture from escaping; this method produces a meal very similar to a steamed potato, while retaining the appearance of a conventionally baked potato. Potato chunks also commonly appear as a stew ingredient. Potatoes are boiled between 10 and 25 minutes, depending on size and type, to become soft.
OTHER THAN FOR EATING
Potatoes are also used for purposes other than eating by humans, for example:
Potatoes are used to brew alcoholic beverages such as vodka, poitín, or akvavit.
They are also used as fodder for livestock. Livestock-grade potatoes, considered too small and/or blemished to sell or market for human use but suitable for fodder use, have been called chats in some dialects. They may be stored in bins until use; they are sometimes ensiled. Some farmers prefer to steam them rather than feed them raw and are equipped to do so efficiently.
Potato starch is used in the food industry as a thickener and binder for soups and sauces, in the textile industry as an adhesive, and for the manufacturing of papers and boards.
Maine companies are exploring the possibilities of using waste potatoes to obtain polylactic acid for use in plastic products; other research projects seek ways to use the starch as a base for biodegradable packaging.
Potato skins, along with honey, are a folk remedy for burns in India. Burn centres in India have experimented with the use of the thin outer skin layer to protect burns while healing.
Potatoes (mainly Russets) are commonly used in plant research. The consistent parenchyma tissue, the clonal nature of the plant and the low metabolic activity provide a very nice "model tissue" for experimentation. Wound-response studies are often done on potato tuber tissue, as are electron transport experiments. In this respect, potato tuber tissue is similar to Drosophila melanogaster, Caenorhabditis elegans and Escherichia coli: they are all "standard" research organisms.
Potatoes have been delivered with personalized messages as a novelty. Potato delivery services include Potato Parcel and Mail A Spud.

Danny has Waardenburg's Syndrome which is a genetic disorder. I need to update his look to include it which for him means a white lock at his forehead, two differently colored eyes, and some possible pigmentation differentials.
Love these boys to death! Danny was quick to be shelled and Glenn has gone through a few versions. I think I like this one for Glenn though he still needs to be tweaked. I definitely need a half decent wig for him- I suck at cutting and styling for him. If this fiber wig I butchered for him (turned it backwards) had sideburns, it might work with a but more shortening and a lot of hair product. Hmm. WIP, definitely.

Scientific Name: Ursus maritimus
Description : Polar bears are considered the largest land carnivores in the world, matched only by very large individual Kodiak brown bears. Both sexes differ in size throughout their range; males being much larger than females and continuing to grow for a longer period of time. These bears have long, massive skulls, necks and bodies with long legs and large paws. Ears and tail are short. The nose is more prominent or “Roman†with a black rhinarium (nose pad). The tongue is black and the eyes brown. The surface of the skin is also black. Fur colour varies slightly with the season: new coats grown just prior to the winter season are very white appearing as slightly creamy white against the stark white of their icy winter environment. This pelage is thick, coarse and long with dense underfur. Guard hairs, found throughout the pelage, are shiny, almost glossy, oily and waterproof and have hollow shafts. Polar bears moult annually between the end of May and August. The coat becomes thinner and has a yellow wash or is almost a golden colour.
Male polar bears weigh between 400 – 600 kg, and have been recorded up to a maximum of 800 kg. Females are smaller than the males weighing up to 300 kg, and when pregnant up to 460 kg. Polar bears are 2.5 – 3.5 m long.
Distribution : The polar bear is circumpolar in distribution, inhabiting all Arctic seas and coastlines. It is found on the pack-ice off the Alaskan coast north of Bering Strait, off the coasts of Greenland and along the Eurasian Arctic coast from Spitsbergen to Wrangell Island. Rare stragglers reach Iceland. Individual bears have been seen on the frozen Arctic Ocean as far as latitude 88 degrees North, only 2 degrees from the North Pole. In Canada, they are found along the Arctic coasts from Alaska to Labrador and from the tip of James Bay to northern Ellesmere Island. Polar bears do roam as far as 150 kilometres inland into the coniferous forests, where they live very differently from the polar bears which belong to the high Arctic.
Habitat : They prefer areas of annual ice, which they use as a hunting platform and protective cover. This includes snow-drifted pressure ridges, refrozen cracks and areas of open water surrounded by ice. In areas where the pack ice melts by mid to late summer they come inland and live in coniferous forest areas. Here they remain until the ice re-freezes. Areas of solidly frozen sea ice and the open seas are avoided. Generally they are most common along coastal areas. Some do enter the permanent pack ice.
Food : The ringed seal is by far the most common prey. They also eat bearded seal, harp seal and hooded seal. Young walrus are sometimes taken. During the summer months they feed upon the shoreline carrion, fish, mussels, crabs, starfish, lemmings and the eggs and nestling young of waterfowl and cliff-dwelling birds. They will also graze on kelp, grasses and eat mushrooms and crowberries.
Reproduction and Development : Normally they are solitary animals outside the breeding season, the exception being a mother with cubs. Polar bears mate in mid-summer. Females first start to breed at 3 to 5 years of age. In April and May adult females are in oestrus and ready to accept a mate. They are polyandrous, meaning one female will mate with more than one male in one breeding season. Males fight among themselves for the female’s attention and a couple will pair off for a period of a few days to two weeks. With females, delayed implantation occurs, the fertilized egg does not implant in the uterus until mid-September to mid-October. Embryonic development begins at this time. Gestation periods, therefore, vary a great deal when including this period of delay. Females choose suitable locations to build their maternity dens in mid-October and retreat to them for the winter season. They give birth to one to four cubs somewhere between late November and early January. Twins are most common. The newborns are small; 25 to 30 cm long and weigh less than 1 kg. They are covered with very fine hair, appearing almost naked and their eyes are closed. Their eyes open at 6 weeks. Growth is very quick; at two months their fur has thickened; they weigh about 5 kg and move about the den. By mid-March to early April, when the den is opened, the cubs weigh about 10 kg and are surprisingly strong. The cubs suckle for nine months, occasionally one year. They are very dependent on their mother and stay with her for two years. At that time they weigh 90 - 180 kg and are half grown.
Adaptations : Polar bears are wonderfully adapted to their Arctic surroundings.
Locomotion. On land a shuffling walk may be increased to a rolling gallop of 40 km/h and can outrun caribou over a short distance. Bears are often seen standing high on their hind legs, necks stretched to scan the landscape. On thin ice, legs are spread to distribute body mass. Thickly padded and furred soles allow the bear to move quietly as well as providing good traction. Small bumps and cavities on the soles act like suction cups keeping bears from slipping on the ice. The claws are used to dig into icy slopes and to grip prey. They are strong swimmers, paddling with their forefeet only and trailing their hind feet which act as a rudder. They can stay submerged for over one minute, keeping their eyes open. They swim at a speed of approximately 6.4 km/h, often covering long distances.
Insulation. Polar bears have a thick layer of sub-cutaneous fat and very dense underfur with several layers of glossy guard hair on the outside. Their pelt is much thicker in winter and provides excellent insulation. The fat layer also adds to buoyancy in the water. Water is shed easily from the oily waterproof fur. Small, furry ears have a heavy network of blood vessels, keeping them warm and conserving heat. The tail is short and rounded also conserving heat. Fur is very dense around the soles of the feet.
Pelage. The creamy white appearance of the coat allows the bear to be inconspicuous when hunting seal. Each hair is similar to an optical fibre; colourless and hollow. Being translucent, it reflects the heat from the sun down to the base of the hair, where it is absorbed by the black skin. Whiteness comes from reflection of light rather than pigmentation.
Hunting. Bears use their keen sense of smell to detect seal breathing holes. These can be up to a kilometer away and covered by a layer of snow and ice. They will stand or lie by the seal’s blowhole in the ice for hours; they may swim towards seals resting on the ice flows with only their nose showing above the water. They will dive quietly, then swim up to the ice edge and jump out on the seal, and will also crawl towards a sunbathing seal using every piece of raised ice to conceal the approach.
Denning. Both sexes occupy dens for shelter. Topographic factors influence the den sites. In Canadian core areas, dens frequently occur on south-facing slopes where northerly prevailing winds create the best drifts, where the wind-chill is least and insulation from received solar radiation is greatest. One of the three largest denning areas worldwide is in Canada. There are three main types of winter refuges: maternity dens, temporary dens and winter shelters. During the winter any bear may dig a temporary den and use it for a few days during a storm, or take shelter in a natural cavity. Winter shelters are used for longer periods of time as resting places. This type of shelter is usually roomier with additional features such as alcoves, porches and ventilation holes. Bears do not hibernate in the strict sense of the word; they have the ability to slow down their metabolism to conserve energy at any time of year. The state of self-induced lethargy while in the shelter allows them to preserve their vital fat reserves. During this time, the body temperature of the polar bear decreases by a few degrees from normal and the respiration rates are markedly reduced. Maternity dens are built and occupied by pregnant females and can vary in size. The denning chamber is at the upper end of an entrance tunnel 1 to 2 m long. It averages 1.5 m in diameter with a height of 90 to 100cm in the middle. Drifting snow seals the entrance. The chamber is higher than the tunnel, trapping bear body heat inside. Dens not only provide a safe place to give birth to her cubs, but are also a place of protection for the cubs during their first few months. During this time she does not leave the den, remaining with her cubs and living on her reserves of fat. In the spring, with her fat severely depleted she must leave to find food to sustain herself and her cubs. After they leave the maternity den she will build temporary refuges in which to nurse, rest and shelter her young cubs and warms them as they all sleep together. She heads with her cubs towards the nearest supply of food, usually towards pack ice.
Sight and sounds. Polar bears have good eyesight. Their eyes have inner eyelids that keep the glare of the sun on snow and ice from blinding them. When defending a food source from other bears they use a deep growl. They hiss and snort to show aggression. Angry bears use loud roars and growls. Mothers scold cubs with a low growl.
Threats to Survival : Polar bears are one of the animals most threatened by global warming. They depend entirely on sea ice as a platform from which to hunt seals. Reduction of the total ice cover in the Arctic is a serious concern globally. When the ice does not form or forms too late in the season many polar bears starve. In Hudson Bay, scientists have found the main cause of death for cubs to be either lack of food or lack of fat on nursing mothers. Exploitation of minerals and fossil fuels in the Arctic pose a continuous threat. Of the oil and natural gas deposits globally, 20% are located in the Arctic. As the ice cap recedes these become more accessible. Countries are competing which each other in claiming ownership of Arctic and its resources. This can only result in further and more drastic impact on polar bear habitat.
