I have been interested in how useful the new 70-200 F4 VR lens will be for close-up photography. The 1m minimum focus distance is reported to give 0.274x magnification, which is useful for larger insects, especially on a crop body. Not all lenses impress at their closes focus point, so I made some amateur comparisons with the 70-300VR-G, the 105 VR micronikkor with TC1.7EII, and the Cosina Voigtlander 180mm f4 apo-lanthar. In addition, I combined the TC1.7EII with the 70-200 F4 VR and compared this combination with the 70-300 VR-G and the 300 F4 AFS, all at close focus distances.
From left to right: Voigtlander 180 F4 apo-Lanthar; Micronikkor 105 F2.8/G ED VR with TC1.7EII; Nikkor 70-200 F4/G ED VR; Nikkor 70-300 F4.5-5.6/G ED VR; AFS Nikkor 300 F4D ED. The Voigtlander and 70-300 are shown extended to closest focus position, they would be shorter otherwise. Te others are all internal focussing.
My initial conclusions are that, between 70-200mm there is not much to choose between the close focus results of the 70-200 F4 VR and the 70-300 VR. Of course the new lens gives you F4, and maybe it is also a touch better a wider apertures. If you want reach, and who doesn’t, the 70-200VR/TC1.7EII combination does not lose much at 100-200mm focal lengths, and clearly superior at 300mm. Not surprisingly the 300mm F4 AFS is better still, and gives you two extra stops. On the other hand, it’s not a zoom, and lacks VR. Whether the advantages of the VR zoom + TC will outweigh the optical excellence of the prime in real life shooting remains to be seen. A lot of closeups will be at F11 or beyond, but then if you use flash then VR is not necessary even handheld. It would be interesting to test the 70-200VR with the TC1.4EII and TC2.0EIII also.

My computer desk chair has a back made of a fabric with large holes in it, making it very useful for the cats (Archie demonstrates here) to grab onto it and basically render themselves impossible to move away from the chair.
This young Fallow Deer didn't seem too impressed with the Jackdaws, trying to help themselves to his fur to line their nests. They will put up with it to a degree, as they are starting to moult their winter coats and the Jackdaws also provide a useful bug picking service - but these two were getting a bit too cheeky!

Here I am again quite late in the afternoon and as much as I enjoy my mostly Internet free early mornings, I 've missed starting my day from here...so I hope to find a good balance in the coming days combining it all.
Today there are three different blog posts prepared over at Domestic stories, introducing you to the newly launched Chosen Three Teusdays.
There are three Etsy shops accumulated together, I not only love, but have also visited and made purchases myself at.
They are chosen and highly recommeded for they meet all my personal style and quality standards. My thoughts are that you might also enjoy visiting them for inspiration and not only.
I'll be sharing the direct links under the collages to be posted right after this picture.
In the meantime....
Hope you are all spending lovely Teusdays! ~ Ivy , xx

A banana is an edible fruit, botanically a berry, produced by several kinds of large herbaceous flowering plants in the genus Musa. (In some countries, bananas used for cooking may be called plantains.) The fruit is variable in size, color and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind which may be green, yellow, red, purple, or brown when ripe. The fruits grow in clusters hanging from the top of the plant. Almost all modern edible parthenocarpic (seedless) bananas come from two wild species – Musa acuminata and Musa balbisiana. The scientific names of most cultivated bananas are Musa acuminata, Musa balbisiana, and Musa × paradisiaca for the hybrid Musa acuminata × M. balbisiana, depending on their genomic constitution. The old scientific name Musa sapientum is no longer used.
Musa species are native to tropical Indomalaya and Australia, and are likely to have been first domesticated in Papua New Guinea. They are grown in at least 107 countries, primarily for their fruit, and to a lesser extent to make fiber, banana wine and banana beer and as ornamental plants.
Worldwide, there is no sharp distinction between "bananas" and "plantains". Especially in the Americas and Europe, "banana" usually refers to soft, sweet, dessert bananas, particularly those of the Cavendish group, which are the main exports from banana-growing countries. By contrast, Musa cultivars with firmer, starchier fruit are called "plantains". In other regions, such as Southeast Asia, many more kinds of banana are grown and eaten, so the simple two-fold distinction is not useful and is not made in local languages.
The term "banana" is also used as the common name for the plants which produce the fruit. This can extend to other members of the genus Musa like the scarlet banana (Musa coccinea), pink banana (Musa velutina) and the Fe'i bananas. It can also refer to members of the genus Ensete, like the snow banana (Ensete glaucum) and the economically important false banana (Ensete ventricosum). Both genera are classified under the banana family, Musaceae.
DESCRIPTION
The banana plant is the largest herbaceous flowering plant. All the above-ground parts of a banana plant grow from a structure usually called a "corm". Plants are normally tall and fairly sturdy, and are often mistaken for trees, but what appears to be a trunk is actually a "false stem" or pseudostem. Bananas grow in a wide variety of soils, as long as the soil is at least 60 cm deep, has good drainage and is not compacted. The leaves of banana plants are composed of a "stalk" (petiole) and a blade (lamina). The base of the petiole widens to form a sheath; the tightly packed sheaths make up the pseudostem, which is all that supports the plant. The edges of the sheath meet when it is first produced, making it tubular. As new growth occurs in the centre of the pseudostem the edges are forced apart. Cultivated banana plants vary in height depending on the variety and growing conditions. Most are around 5 m tall, with a range from 'Dwarf Cavendish' plants at around 3 m to 'Gros Michel' at 7 m or more. Leaves are spirally arranged and may grow 2.7 metres long and 60 cm wide. They are easily torn by the wind, resulting in the familiar frond look.
When a banana plant is mature, the corm stops producing new leaves and begins to form a flower spike or inflorescence. A stem develops which grows up inside the pseudostem, carrying the immature inflorescence until eventually it emerges at the top. Each pseudostem normally produces a single inflorescence, also known as the "banana heart". (More are sometimes produced; an exceptional plant in the Philippines produced five.) After fruiting, the pseudostem dies, but offshoots will normally have developed from the base, so that the plant as a whole is perennial. In the plantation system of cultivation, only one of the offshoots will be allowed to develop in order to maintain spacing. The inflorescence contains many bracts (sometimes incorrectly referred to as petals) between rows of flowers. The female flowers (which can develop into fruit) appear in rows further up the stem (closer to the leaves) from the rows of male flowers. The ovary is inferior, meaning that the tiny petals and other flower parts appear at the tip of the ovary.
The banana fruits develop from the banana heart, in a large hanging cluster, made up of tiers (called "hands"), with up to 20 fruit to a tier. The hanging cluster is known as a bunch, comprising 3–20 tiers, or commercially as a "banana stem", and can weigh 30–50 kilograms. Individual banana fruits (commonly known as a banana or "finger") average 125 grams, of which approximately 75% is water and 25% dry matter.
The fruit has been described as a "leathery berry". There is a protective outer layer (a peel or skin) with numerous long, thin strings (the phloem bundles), which run lengthwise between the skin and the edible inner portion. The inner part of the common yellow dessert variety can be split lengthwise into three sections that correspond to the inner portions of the three carpels by manually deforming the unopened fruit. In cultivated varieties, the seeds are diminished nearly to non-existence; their remnants are tiny black specks in the interior of the fruit.
Bananas are naturally slightly radioactive, more so than most other fruits, because of their potassium content and the small amounts of the isotope potassium-40 found in naturally occurring potassium. The banana equivalent dose of radiation is sometimes used in nuclear communication to compare radiation levels and exposures.
ETYMOLOGY
The word banana is thought to be of West African origin, possibly from the Wolof word banaana, and passed into English via Spanish or Portuguese.
TAXONOMY
The genus Musa was created by Carl Linnaeus in 1753. The name may be derived from Antonius Musa, physician to the Emperor Augustus, or Linnaeus may have adapted the Arabic word for banana, mauz. Musa is in the family Musaceae. The APG III system assigns Musaceae to the order Zingiberales, part of the commelinid clade of the monocotyledonous flowering plants. Some 70 species of Musa were recognized by the World Checklist of Selected Plant Families as of January 2013; several produce edible fruit, while others are cultivated as ornamentals.
The classification of cultivated bananas has long been a problematic issue for taxonomists. Linnaeus originally placed bananas into two species based only on their uses as food: Musa sapientum for dessert bananas and Musa paradisiaca for plantains. Subsequently further species names were added. However, this approach proved inadequate to address the sheer number of cultivars existing in the primary center of diversity of the genus, Southeast Asia. Many of these cultivars were given names which proved to be synonyms.
In a series of papers published in 1947 onwards, Ernest Cheesman showed that Linnaeus's Musa sapientum and Musa paradisiaca were actually cultivars and descendants of two wild seed-producing species, Musa acuminata and Musa balbisiana, both first described by Luigi Aloysius Colla. He recommended the abolition of Linnaeus's species in favor of reclassifying bananas according to three morphologically distinct groups of cultivars – those primarily exhibiting the botanical characteristics of Musa balbisiana, those primarily exhibiting the botanical characteristics of Musa acuminata, and those with characteristics that are the combination of the two. Researchers Norman Simmonds and Ken Shepherd proposed a genome-based nomenclature system in 1955. This system eliminated almost all the difficulties and inconsistencies of the earlier classification of bananas based on assigning scientific names to cultivated varieties. Despite this, the original names are still recognized by some authorities today, leading to confusion.
The currently accepted scientific names for most groups of cultivated bananas are Musa acuminata Colla and Musa balbisiana Colla for the ancestral species, and Musa × paradisiaca L. for the hybrid M. acuminata × M. balbisiana.
Synonyms of M. × paradisica include:
A large number of subspecific and varietial names of M. × paradisiaca, including M. p. subsp. sapientum (L.) Kuntze
Musa × dacca Horan.
Musa × sapidisiaca K.C.Jacob, nom. superfl.
Musa × sapientum L., and a large number of its varietal names, including M. × sapientum var. paradisiaca (L.) Baker, nom. illeg.
Generally, modern classifications of banana cultivars follow Simmonds and Shepherd's system. Cultivars are placed in groups based on the number of chromosomes they have and which species they are derived from. Thus the Latundan banana is placed in the AAB Group, showing that it is a triploid derived from both M. acuminata (A) and M. balbisiana (B). For a list of the cultivars classified under this system see List of banana cultivars.
In 2012, a team of scientists announced they had achieved a draft sequence of the genome of Musa acuminata.
BANANAS & PLANTAINS
In regions such as North America and Europe, Musa fruits offered for sale can be divided into "bananas" and "plantains", based on their intended use as food. Thus the banana producer and distributor Chiquita produces publicity material for the American market which says that "a plantain is not a banana". The stated differences are that plantains are more starchy and less sweet; they are eaten cooked rather than raw; they have thicker skin, which may be green, yellow or black; and they can be used at any stage of ripeness. Linnaeus made the same distinction between plantains and bananas when first naming two "species" of Musa. Members of the "plantain subgroup" of banana cultivars, most important as food in West Africa and Latin America, correspond to the Chiquita description, having long pointed fruit. They are described by Ploetz et al. as "true" plantains, distinct from other cooking bananas. The cooking bananas of East Africa belong to a different group, the East African Highland bananas, so would not qualify as "true" plantains on this definition.
An alternative approach divides bananas into dessert bananas and cooking bananas, with plantains being one of the subgroups of cooking bananas. Triploid cultivars derived solely from M. acuminata are examples of "dessert bananas", whereas triploid cultivars derived from the hybrid between M. acuminata and M. balbinosa (in particular the plantain subgroup of the AAB Group) are "plantains". Small farmers in Colombia grow a much wider range of cultivars than large commercial plantations. A study of these cultivars showed that they could be placed into at least three groups based on their characteristics: dessert bananas, non-plantain cooking bananas, and plantains, although there were overlaps between dessert and cooking bananas.
In Southeast Asia – the center of diversity for bananas, both wild and cultivated – the distinction between "bananas" and "plantains" does not work, according to Valmayor et al. Many bananas are used both raw and cooked. There are starchy cooking bananas which are smaller than those eaten raw. The range of colors, sizes and shapes is far wider than in those grown or sold in Africa, Europe or the Americas.[35] Southeast Asian languages do not make the distinction between "bananas" and "plantains" that is made in English (and Spanish). Thus both Cavendish cultivars, the classic yellow dessert bananas, and Saba cultivars, used mainly for cooking, are called pisang in Malaysia and Indonesia, kluai in Thailand and chuoi in Vietnam. Fe'i bananas, grown and eaten in the islands of the Pacific, are derived from entirely different wild species than traditional bananas and plantains. Most Fe'i bananas are cooked, but Karat bananas, which are short and squat with bright red skins, very different from the usual yellow dessert bananas, are eaten raw.
In summary, in commerce in Europe and the Americas (although not in small-scale cultivation), it is possible to distinguish between "bananas", which are eaten raw, and "plantains", which are cooked. In other regions of the world, particularly India, Southeast Asia and the islands of the Pacific, there are many more kinds of banana and the two-fold distinction is not useful and not made in local languages. Plantains are one of many kinds of cooking bananas, which are not always distinct from dessert bananas.
HISTORICAL CULTIVATION
Farmers in Southeast Asia and Papua New Guinea first domesticated bananas. Recent archaeological and palaeoenvironmental evidence at Kuk Swamp in the Western Highlands Province of Papua New Guinea suggests that banana cultivation there goes back to at least 5000 BCE, and possibly to 8000 BCE. It is likely that other species were later and independently domesticated elsewhere in Southeast Asia. Southeast Asia is the region of primary diversity of the banana. Areas of secondary diversity are found in Africa, indicating a long history of banana cultivation in the region.
Phytolith discoveries in Cameroon dating to the first millennium BCE triggered an as yet unresolved debate about the date of first cultivation in Africa. There is linguistic evidence that bananas were known in Madagascar around that time. The earliest prior evidence indicates that cultivation dates to no earlier than late 6th century CE. It is likely, however, that bananas were brought at least to Madagascar if not to the East African coast during the phase of Malagasy colonization of the island from South East Asia c. 400 CE.
The banana may also have been present in isolated locations elsewhere in the Middle East on the eve of Islam. The spread of Islam was followed by far-reaching diffusion. There are numerous references to it in Islamic texts (such as poems and hadiths) beginning in the 9th century. By the 10th century the banana appears in texts from Palestine and Egypt. From there it diffused into North Africa and Muslim Iberia. During the medieval ages, bananas from Granada were considered among the best in the Arab world. In 650, Islamic conquerors brought the banana to Palestine. Today, banana consumption increases significantly in Islamic countries during Ramadan, the month of daylight fasting.
Bananas were certainly grown in the Christian Kingdom of Cyprus by the late medieval period. Writing in 1458, the Italian traveller and writer Gabriele Capodilista wrote favourably of the extensive farm produce of the estates at Episkopi, near modern day Limassol, including the region's banana plantations.
Bananas were introduced to the Americas by Portuguese sailors who brought the fruits from West Africa in the 16th century.
Many wild banana species as well as cultivars exist in extraordinary diversity in New Guinea, Malaysia, Indonesia, China, and the Philippines.
There are fuzzy bananas whose skins are bubblegum pink; green-and-white striped bananas with pulp the color of orange sherbet; bananas that, when cooked, taste like strawberries. The Double Mahoi plant can produce two bunches at once. The Chinese name of the aromatic Go San Heong banana means 'You can smell it from the next mountain.' The fingers on one banana plant grow fused; another produces bunches of a thousand fingers, each only an inch long.
—Mike Peed, The New Yorker
In 1999 archaeologists in London discovered what they believed to be the oldest banana in the UK, in a Tudor rubbish tip.
PLANTATION CULTIVATION IN THE CARIBBEAN,
CENTRAL & SOUTH AMERICA
In the 15th and 16th centuries, Portuguese colonists started banana plantations in the Atlantic Islands, Brazil, and western Africa. North Americans began consuming bananas on a small scale at very high prices shortly after the Civil War, though it was only in the 1880s that it became more widespread. As late as the Victorian Era, bananas were not widely known in Europe, although they were available. Jules Verne introduces bananas to his readers with detailed descriptions in Around the World in Eighty Days (1872).
The earliest modern plantations originated in Jamaica and the related Western Caribbean Zone, including most of Central America. It involved the combination of modern transportation networks of steamships and railroads with the development of refrigeration that allowed bananas to have more time between harvesting and ripening. North America shippers like Lorenzo Dow Baker and Andrew Preston, the founders of the Boston Fruit Company started this process in the 1870s, but railroad builders like Minor C Keith also participated, eventually culminating in the multi-national giant corporations like today's Chiquita Brands International and Dole. These companies were monopolistic, vertically integrated (meaning they controlled growing, processing, shipping and marketing) and usually used political manipulation to build enclave economies (economies that were internally self-sufficient, virtually tax exempt, and export oriented that contribute very little to the host economy). Their political maneuvers, which gave rise to the term Banana republic for states like Honduras and Guatemala, included working with local elites and their rivalries to influence politics or playing the international interests of the United States, especially during the Cold War, to keep the political climate favorable to their interests.
PEASANT CULTIVATION FOR EXPORT IN THE CARIBBEAN
The vast majority of the world's bananas today are cultivated for family consumption or for sale on local markets. India is the world leader in this sort of production, but many other Asian and African countries where climate and soil conditions allow cultivation also host large populations of banana growers who sell at least some of their crop.
There are peasant sector banana growers who produce for the world market in the Caribbean, however. The Windward Islands are notable for the growing, largely of Cavendish bananas, for an international market, generally in Europe but also in North America. In the Caribbean, and especially in Dominica where this sort of cultivation is widespread, holdings are in the 1–2 acre range. In many cases the farmer earns additional money from other crops, from engaging in labor outside the farm, and from a share of the earnings of relatives living overseas. This style of cultivation often was popular in the islands as bananas required little labor input and brought welcome extra income. Banana crops are vulnerable to destruction by high winds, such as tropical storms or cyclones.
After the signing of the NAFTA agreements in the 1990s, however, the tide turned against peasant producers. Their costs of production were relatively high and the ending of favorable tariff and other supports, especially in the European Economic Community, made it difficult for peasant producers to compete with the bananas grown on large plantations by the well capitalized firms like Chiquita and Dole. Not only did the large companies have access to cheap labor in the areas they worked, but they were better able to afford modern agronomic advances such as fertilization. The "dollar banana" produced by these concerns made the profit margins for peasant bananas unsustainable.
Caribbean countries have sought to redress this problem by providing government supported agronomic services and helping to organize producers' cooperatives. They have also been supporters of the Fair Trade movement which seeks to balance the inequities in the world trade in commodities.
EAST AFRICA
Most farms supply local consumption. Cooking bananas represent a major food source and a major income source for smallhold farmers. In east Africa, highland bananas are of greatest importance as a staple food crop. In countries such as Uganda, Burundi, and Rwanda per capita consumption has been estimated at 45 kilograms per year, the highest in the world.
MODERN CULTIVATION
All widely cultivated bananas today descend from the two wild bananas Musa acuminata and Musa balbisiana. While the original wild bananas contained large seeds, diploid or polyploid cultivars (some being hybrids) with tiny seeds are preferred for human raw fruit consumption. These are propagated asexually from offshoots. The plant is allowed to produce two shoots at a time; a larger one for immediate fruiting and a smaller "sucker" or "follower" to produce fruit in 6–8 months. The life of a banana plantation is 25 years or longer, during which time the individual stools or planting sites may move slightly from their original positions as lateral rhizome formation dictates.
Cultivated bananas are parthenocarpic, i.e. the flesh of the fruit swells and ripens without its seeds being fertilized and developing. Lacking viable seeds, propagation typically involves farmers removing and transplanting part of the underground stem (called a corm). Usually this is done by carefully removing a sucker (a vertical shoot that develops from the base of the banana pseudostem) with some roots intact. However, small sympodial corms, representing not yet elongated suckers, are easier to transplant and can be left out of the ground for up to two weeks; they require minimal care and can be shipped in bulk.It is not necessary to include the corm or root structure to propagate bananas; severed suckers without root material can be propagated in damp sand, although this takes somewhat longer.In some countries, commercial propagation occurs by means of tissue culture. This method is preferred since it ensures disease-free planting material. When using vegetative parts such as suckers for propagation, there is a risk of transmitting diseases (especially the devastating Panama disease).As a non-seasonal crop, bananas are available fresh year-round.

In global commerce in 2009, by far the most important cultivars belonged to the triploid AAA group of Musa acuminata, commonly referred to as Cavendish group bananas. They accounted for the majority of banana exports, despite only coming into existence in 1836. The cultivars Dwarf Cavendish and Grand Nain (Chiquita Banana) gained popularity in the 1950s after the previous mass-produced cultivar, Gros Michel (also an AAA group cultivar), became commercially unviable due to Panama disease, caused by the fungus Fusarium oxysporum which attacks the roots of the banana plant. Cavendish cultivars are resistant to the Panama Disease but in 2013 there were fears that the Black Sigatoka fungus would in turn make Cavendish bananas unviable.
Ease of transport and shelf life rather than superior taste make the Dwarf Cavendish the main export banana.
Even though it is no longer viable for large scale cultivation, Gros Michel is not extinct and is still grown in areas where Panama disease is not found. Likewise, Dwarf Cavendish and Grand Nain are in no danger of extinction, but they may leave supermarket shelves if disease makes it impossible to supply the global market. It is unclear if any existing cultivar can replace Cavendish bananas, so various hybridisation and genetic engineering programs are attempting to create a disease-resistant, mass-market banana.
RIPENING
Export bananas are picked green, and ripen in special rooms upon arrival in the destination country. These rooms are air-tight and filled with ethylene gas to induce ripening. The vivid yellow color consumers normally associate with supermarket bananas is, in fact, caused by the artificial ripening process. Flavor and texture are also affected by ripening temperature. Bananas are refrigerated to between 13.5 and 15 °C during transport. At lower temperatures, ripening permanently stalls, and the bananas turn gray as cell walls break down. The skin of ripe bananas quickly blackens in the 4 °C environment of a domestic refrigerator, although the fruit inside remains unaffected.
"Tree-ripened" Cavendish bananas have a greenish-yellow appearance which changes to a brownish-yellow as they ripen further. Although both flavor and texture of tree-ripened bananas is generally regarded as superior to any type of green-picked fruit, this reduces shelf life to only 7–10 days.Bananas can be ordered by the retailer "ungassed" (i.e. not treated with ethylene), and may show up at the supermarket fully green. Guineos verdes (green bananas) that have not been gassed will never fully ripen before becoming rotten. Instead of fresh eating, these bananas are best suited to cooking, as seen in Mexican culinary dishes.A 2008 study reported that ripe bananas fluoresce when exposed to ultraviolet light. This property is attributed to the degradation of chlorophyll leading to the accumulation of a fluorescent product in the skin of the fruit. The chlorophyll breakdown product is stabilized by a propionate ester group. Banana-plant leaves also fluoresce in the same way. Green bananas do not fluoresce. The study suggested that this allows animals which can see light in the ultraviolet spectrum (tetrachromats and pentachromats) to more easily detect ripened bananas.
STORAGE & TRANSPORT
Bananas must be transported over long distances from the tropics to world markets. To obtain maximum shelf life, harvest comes before the fruit is mature. The fruit requires careful handling, rapid transport to ports, cooling, and refrigerated shipping. The goal is to prevent the bananas from producing their natural ripening agent, ethylene. This technology allows storage and transport for 3–4 weeks at 13 °C. On arrival, bananas are held at about 17 °C and treated with a low concentration of ethylene. After a few days, the fruit begins to ripen and is distributed for final sale. Unripe bananas can not be held in home refrigerators because they suffer from the cold. Ripe bananas can be held for a few days at home. If bananas are too green, they can be put in a brown paper bag with an apple or tomato overnight to speed up the ripening process.
Carbon dioxide (which bananas produce) and ethylene absorbents extend fruit life even at high temperatures. This effect can be exploited by packing banana in a polyethylene bag and including an ethylene absorbent, e.g., potassium permanganate, on an inert carrier. The bag is then sealed with a band or string. This treatment has been shown to more than double lifespans up to 3–4 weeks without the need for refrigeration.
FRUIT
Bananas are a staple starch for many tropical populations. Depending upon cultivar and ripeness, the flesh can vary in taste from starchy to sweet, and texture from firm to mushy. Both the skin and inner part can be eaten raw or cooked. The primary component of the aroma of fresh bananas is isoamyl acetate (also known as banana oil), which, along with several other compounds such as butyl acetate and isobutyl acetate, is a significant contributor to banana flavor.
During the ripening process, bananas produce the gas ethylene, which acts as a plant hormone and indirectly affects the flavor. Among other things, ethylene stimulates the formation of amylase, an enzyme that breaks down starch into sugar, influencing the taste of bananas. The greener, less ripe bananas contain higher levels of starch and, consequently, have a "starchier" taste. On the other hand, yellow bananas taste sweeter due to higher sugar concentrations. Furthermore, ethylene signals the production of pectinase, an enzyme which breaks down the pectin between the cells of the banana, causing the banana to soften as it ripens.
Bananas are eaten deep fried, baked in their skin in a split bamboo, or steamed in glutinous rice wrapped in a banana leaf. Bananas can be made into jam. Banana pancakes are popular amongst backpackers and other travelers in South Asia and Southeast Asia. This has elicited the expression Banana Pancake Trail for those places in Asia that cater to this group of travelers. Banana chips are a snack produced from sliced dehydrated or fried banana or plantain, which have a dark brown color and an intense banana taste. Dried bananas are also ground to make banana flour. Extracting juice is difficult, because when a banana is compressed, it simply turns to pulp. Bananas feature prominently in Philippine cuisine, being part of traditional dishes and desserts like maruya, turrón, and halo-halo or saba con yelo. Most of these dishes use the Saba or Cardaba banana cultivar. Bananas are also commonly used in cuisine in the South-Indian state of Kerala, where they are steamed (puzhungiyathu), made into curries, fried into chips (upperi) or fried in batter (pazhampori). Pisang goreng, bananas fried with batter similar to the Filipino maruya or Kerala pazhampori, is a popular dessert in Malaysia, Singapore, and Indonesia. A similar dish is known in the United Kingdom and United States as banana fritters.
Plantains are used in various stews and curries or cooked, baked or mashed in much the same way as potatoes, such as the Pazham Pachadi prepared in Kerala.
Seeded bananas (Musa balbisiana), one of the forerunners of the common domesticated banana, are sold in markets in Indonesia.
FLOWER
Banana hearts are used as a vegetable in South Asian and Southeast Asian cuisine, either raw or steamed with dips or cooked in soups, curries and fried foods. The flavor resembles that of artichoke. As with artichokes, both the fleshy part of the bracts and the heart are edible.
LEAVES
Banana leaves are large, flexible, and waterproof. They are often used as ecologically friendly disposable food containers or as "plates" in South Asia and several Southeast Asian countries. In Indonesian cuisine, banana leaf is employed in cooking method called pepes and botok; the banana leaf packages containing food ingredients and spices are cooked on steam, in boiled water or grilled on charcoal. In the South Indian states of Tamil Nadu, Karnataka, Andhra Pradesh and Kerala in every occasion the food must be served in a banana leaf and as a part of the food a banana is served. Steamed with dishes they impart a subtle sweet flavor. They often serve as a wrapping for grilling food. The leaves contain the juices, protect food from burning and add a subtle flavor. In Tamil Nadu (India) leaves are fully dried and used as packing material for food stuffs and also making cups to hold liquid foods. In Central American countries, banana leaves are often used as wrappers for tamales.
TRUNK
The tender core of the banana plant's trunk is also used in South Asian and Southeast Asian cuisine, and notably in the Burmese dish mohinga.
FIBER
TEXTILES
The banana plant has long been a source of fiber for high quality textiles. In Japan, banana cultivation for clothing and household use dates back to at least the 13th century. In the Japanese system, leaves and shoots are cut from the plant periodically to ensure softness. Harvested shoots are first boiled in lye to prepare fibers for yarn-making. These banana shoots produce fibers of varying degrees of softness, yielding yarns and textiles with differing qualities for specific uses. For example, the outermost fibers of the shoots are the coarsest, and are suitable for tablecloths, while the softest innermost fibers are desirable for kimono and kamishimo. This traditional Japanese cloth-making process requires many steps, all performed by hand.
In a Nepalese system the trunk is harvested instead, and small pieces are subjected to a softening process, mechanical fiber extraction, bleaching and drying. After that, the fibers are sent to the Kathmandu Valley for use in rugs with a silk-like texture. These banana fiber rugs are woven by traditional Nepalese hand-knotting methods, and are sold RugMark certified.
In South Indian state of Tamil Nadu after harvesting for fruit the trunk (outer layer of the shoot) is made into fine thread used in making of flower garlands instead of thread.
PAPER
Banana fiber is used in the production of banana paper. Banana paper is made from two different parts: the bark of the banana plant, mainly used for artistic purposes, or from the fibers of the stem and non-usable fruits. The paper is either hand-made or by industrial process.

Maps. You've got to love them. They can come in very useful. Although I doubt this map will be guiding anyone anywhere again. Destiny has something entirely different in store for this particular map. She's become art.
Who hasn't heard about those infamous Bunga Bunga parties hosted by Italian Prime Minister Silvio Berlusconi? Well I have and i have to say they sound like they would certainly be pretty interesting to say the least. What quite goes on at a Bunga Bunga party i hear you say and it's still a hot topic of conversation but one meaning is "an orgy involving a powerful leader"; it was allegedly taught to Silvio Berlusconi by Muammar al-gaddafi. Now you can see why i say pretty interesting.
This girl looks like she's ready to go and hot to trot, Bunga Bunga indeed! The map she is painted on is of course Italy,well it just had to be didn't it?

BR Standard 4MT 2-6-4T No. 80136
Following Nationalisation of the railways in 1948, the new British Railways inherited numbers of large tank engines which were particularly useful for commuter and branch line services, and while the former LMS and GWR regions had a good supply, other regions did not. A building programme was instituted, with Robert Riddles in Brighton drawing up a new loco based on the LMS 2-6-4T, whose design traces back to Henry Fowler's 1927 tank. 155 locomotives were built between 1951 and 1956, mostly in Brighton with small batches in Derby and Doncaster.
Designated Standard Class 4 Tank, the locomotives were distributed throughout the network, except in the Western Region which still had a plentiful supply of ex-Great Western "Large Prairie" tanks. They became particularly associated with the London, Tilbury & Southend line, until it was electrified in 1962, and with Glasgow's suburban services. Four were allocated to the Whitby depot in 1955 - three of them brand-new - but with the arrival of Diesel Multiple-Units to take over local services, they departed again between 1956 and 1958.
80136 was built in Brighton in 1956, and initially assigned to Plaistow and working the Tilbury line. In 1962 a change in scenery beckoned and she left for Shrewsbury, and worked in Shropshire and Mid-Wales until her withdrawal in 1965, less than ten years after being built. Like so many locomotives, she sat in Woodham Brothers' scrapyard on Barry Island until 1979. Rescued by Philip Oldfield, she became a labour of love, painstakingly and slowly restored with parts often built from scratch, and based at the Churnet Valley Railway. She first steamed in 1998 and worked at the Churnet Valley and then the Llangollen railway until her boiler ticket expired in 2008.
As with so many locomotives, she then had to wait her turn with work being done on an ad-hoc basis but in 2016 an agreement was reached with the owners to bring her to the NYMR to join her sister loco 80135. With most of the required work having been completed, she arrived in April as a separate boiler and frames, and the Motive Power Depot team at Grosmont reassembled her in record time, with just a month elapsing between remounting the boiler and passing inspection. She returned to regular service in August 2016. www.nymr.co.uk/br-standard-4mt-2-6-4t-no-80136

20 Interesting and Useful Water Facts
Roughly 70 percent of an adult’s body is made up of water.
At birth, water accounts for approximately 80 percent of an infant’s body weight.
A healthy person can drink about three gallons (48 cups) of water per day.
Drinking too much water too quickly can lead to water intoxication. Water intoxication occurs when water dilutes the sodium level in the bloodstream and causes an imbalance of water in the brain.
Water intoxication is most likely to occur during periods of intense athletic performance.
While the daily recommended amount of water is eight cups per day, not all of this water must be consumed in the liquid form. Nearly every food or drink item provides some water to the body.
Soft drinks, coffee, and tea, while made up almost entirely of water, also contain caffeine. Caffeine can act as a mild diuretic, preventing water from traveling to necessary locations in the body.
Pure water (solely hydrogen and oxygen atoms) has a neutral pH of 7, which is neither acidic nor basic.
Water dissolves more substances than any other liquid. Wherever it travels, water carries chemicals, minerals, and nutrients with it.
Somewhere between 70 and 75 percent of the earth’s surface is covered with water.
Much more fresh water is stored under the ground in aquifers than on the earth’s surface.
The earth is a closed system, similar to a terrarium, meaning that it rarely loses or gains extra matter. The same water that existed on the earth millions of years ago is still present today.
The total amount of water on the earth is about 326 million cubic miles of water.
Of all the water on the earth, humans can used only about three tenths of a percent of this water. Such usable water is found in groundwater aquifers, rivers, and freshwater lakes.
The United States uses about 346,000 million gallons of fresh water every day.
The United States uses nearly 80 percent of its water for irrigation and thermoelectric power.
The average person in the United States uses anywhere from 80-100 gallons of water per day. Flushing the toilet actually takes up the largest amount of this water.
Approximately 85 percent of U.S. residents receive their water from public water facilities. The remaining 15 percent supply their own water from private wells or other sources.
By the time a person feels thirsty, his or her body has lost over 1 percent of its total water amount.
The weight a person loses directly after intense physical activity is weight from water, not fat.

Mt Useful is located about 14km in a straight line south west of Licola deep in the Gippsland High Country. At at an altitude of 1434 metres Mt Useful can be snow covered in winter and proved a major obstacle for gold prospectors travelling through the area in the gold rush days of the mid to late 1800's and in fact there are quite a few graves of the early travellers who didnt make it over Mt Useful in the cold winter months.

A banana is an edible fruit, botanically a berry, produced by several kinds of large herbaceous flowering plants in the genus Musa. (In some countries, bananas used for cooking may be called plantains.) The fruit is variable in size, color and firmness, but is usually elongated and curved, with soft flesh rich in starch covered with a rind which may be green, yellow, red, purple, or brown when ripe. The fruits grow in clusters hanging from the top of the plant. Almost all modern edible parthenocarpic (seedless) bananas come from two wild species – Musa acuminata and Musa balbisiana. The scientific names of most cultivated bananas are Musa acuminata, Musa balbisiana, and Musa × paradisiaca for the hybrid Musa acuminata × M. balbisiana, depending on their genomic constitution. The old scientific name Musa sapientum is no longer used.
Musa species are native to tropical Indomalaya and Australia, and are likely to have been first domesticated in Papua New Guinea. They are grown in at least 107 countries, primarily for their fruit, and to a lesser extent to make fiber, banana wine and banana beer and as ornamental plants.
Worldwide, there is no sharp distinction between "bananas" and "plantains". Especially in the Americas and Europe, "banana" usually refers to soft, sweet, dessert bananas, particularly those of the Cavendish group, which are the main exports from banana-growing countries. By contrast, Musa cultivars with firmer, starchier fruit are called "plantains". In other regions, such as Southeast Asia, many more kinds of banana are grown and eaten, so the simple two-fold distinction is not useful and is not made in local languages.
The term "banana" is also used as the common name for the plants which produce the fruit. This can extend to other members of the genus Musa like the scarlet banana (Musa coccinea), pink banana (Musa velutina) and the Fe'i bananas. It can also refer to members of the genus Ensete, like the snow banana (Ensete glaucum) and the economically important false banana (Ensete ventricosum). Both genera are classified under the banana family, Musaceae.
DESCRIPTION
The banana plant is the largest herbaceous flowering plant. All the above-ground parts of a banana plant grow from a structure usually called a "corm". Plants are normally tall and fairly sturdy, and are often mistaken for trees, but what appears to be a trunk is actually a "false stem" or pseudostem. Bananas grow in a wide variety of soils, as long as the soil is at least 60 cm deep, has good drainage and is not compacted. The leaves of banana plants are composed of a "stalk" (petiole) and a blade (lamina). The base of the petiole widens to form a sheath; the tightly packed sheaths make up the pseudostem, which is all that supports the plant. The edges of the sheath meet when it is first produced, making it tubular. As new growth occurs in the centre of the pseudostem the edges are forced apart. Cultivated banana plants vary in height depending on the variety and growing conditions. Most are around 5 m tall, with a range from 'Dwarf Cavendish' plants at around 3 m to 'Gros Michel' at 7 m or more. Leaves are spirally arranged and may grow 2.7 metres long and 60 cm wide. They are easily torn by the wind, resulting in the familiar frond look.
When a banana plant is mature, the corm stops producing new leaves and begins to form a flower spike or inflorescence. A stem develops which grows up inside the pseudostem, carrying the immature inflorescence until eventually it emerges at the top. Each pseudostem normally produces a single inflorescence, also known as the "banana heart". (More are sometimes produced; an exceptional plant in the Philippines produced five.) After fruiting, the pseudostem dies, but offshoots will normally have developed from the base, so that the plant as a whole is perennial. In the plantation system of cultivation, only one of the offshoots will be allowed to develop in order to maintain spacing. The inflorescence contains many bracts (sometimes incorrectly referred to as petals) between rows of flowers. The female flowers (which can develop into fruit) appear in rows further up the stem (closer to the leaves) from the rows of male flowers. The ovary is inferior, meaning that the tiny petals and other flower parts appear at the tip of the ovary.
The banana fruits develop from the banana heart, in a large hanging cluster, made up of tiers (called "hands"), with up to 20 fruit to a tier. The hanging cluster is known as a bunch, comprising 3–20 tiers, or commercially as a "banana stem", and can weigh 30–50 kilograms. Individual banana fruits (commonly known as a banana or "finger") average 125 grams, of which approximately 75% is water and 25% dry matter.
The fruit has been described as a "leathery berry". There is a protective outer layer (a peel or skin) with numerous long, thin strings (the phloem bundles), which run lengthwise between the skin and the edible inner portion. The inner part of the common yellow dessert variety can be split lengthwise into three sections that correspond to the inner portions of the three carpels by manually deforming the unopened fruit. In cultivated varieties, the seeds are diminished nearly to non-existence; their remnants are tiny black specks in the interior of the fruit.
Bananas are naturally slightly radioactive, more so than most other fruits, because of their potassium content and the small amounts of the isotope potassium-40 found in naturally occurring potassium. The banana equivalent dose of radiation is sometimes used in nuclear communication to compare radiation levels and exposures.
ETYMOLOGY
The word banana is thought to be of West African origin, possibly from the Wolof word banaana, and passed into English via Spanish or Portuguese.
TAXONOMY
The genus Musa was created by Carl Linnaeus in 1753. The name may be derived from Antonius Musa, physician to the Emperor Augustus, or Linnaeus may have adapted the Arabic word for banana, mauz. Musa is in the family Musaceae. The APG III system assigns Musaceae to the order Zingiberales, part of the commelinid clade of the monocotyledonous flowering plants. Some 70 species of Musa were recognized by the World Checklist of Selected Plant Families as of January 2013; several produce edible fruit, while others are cultivated as ornamentals.
The classification of cultivated bananas has long been a problematic issue for taxonomists. Linnaeus originally placed bananas into two species based only on their uses as food: Musa sapientum for dessert bananas and Musa paradisiaca for plantains. Subsequently further species names were added. However, this approach proved inadequate to address the sheer number of cultivars existing in the primary center of diversity of the genus, Southeast Asia. Many of these cultivars were given names which proved to be synonyms.
In a series of papers published in 1947 onwards, Ernest Cheesman showed that Linnaeus's Musa sapientum and Musa paradisiaca were actually cultivars and descendants of two wild seed-producing species, Musa acuminata and Musa balbisiana, both first described by Luigi Aloysius Colla. He recommended the abolition of Linnaeus's species in favor of reclassifying bananas according to three morphologically distinct groups of cultivars – those primarily exhibiting the botanical characteristics of Musa balbisiana, those primarily exhibiting the botanical characteristics of Musa acuminata, and those with characteristics that are the combination of the two. Researchers Norman Simmonds and Ken Shepherd proposed a genome-based nomenclature system in 1955. This system eliminated almost all the difficulties and inconsistencies of the earlier classification of bananas based on assigning scientific names to cultivated varieties. Despite this, the original names are still recognized by some authorities today, leading to confusion.
The currently accepted scientific names for most groups of cultivated bananas are Musa acuminata Colla and Musa balbisiana Colla for the ancestral species, and Musa × paradisiaca L. for the hybrid M. acuminata × M. balbisiana.
Synonyms of M. × paradisica include:
A large number of subspecific and varietial names of M. × paradisiaca, including M. p. subsp. sapientum (L.) Kuntze
Musa × dacca Horan.
Musa × sapidisiaca K.C.Jacob, nom. superfl.
Musa × sapientum L., and a large number of its varietal names, including M. × sapientum var. paradisiaca (L.) Baker, nom. illeg.
Generally, modern classifications of banana cultivars follow Simmonds and Shepherd's system. Cultivars are placed in groups based on the number of chromosomes they have and which species they are derived from. Thus the Latundan banana is placed in the AAB Group, showing that it is a triploid derived from both M. acuminata (A) and M. balbisiana (B). For a list of the cultivars classified under this system see List of banana cultivars.
In 2012, a team of scientists announced they had achieved a draft sequence of the genome of Musa acuminata.
BANANAS & PLANTAINS
In regions such as North America and Europe, Musa fruits offered for sale can be divided into "bananas" and "plantains", based on their intended use as food. Thus the banana producer and distributor Chiquita produces publicity material for the American market which says that "a plantain is not a banana". The stated differences are that plantains are more starchy and less sweet; they are eaten cooked rather than raw; they have thicker skin, which may be green, yellow or black; and they can be used at any stage of ripeness. Linnaeus made the same distinction between plantains and bananas when first naming two "species" of Musa. Members of the "plantain subgroup" of banana cultivars, most important as food in West Africa and Latin America, correspond to the Chiquita description, having long pointed fruit. They are described by Ploetz et al. as "true" plantains, distinct from other cooking bananas. The cooking bananas of East Africa belong to a different group, the East African Highland bananas, so would not qualify as "true" plantains on this definition.
An alternative approach divides bananas into dessert bananas and cooking bananas, with plantains being one of the subgroups of cooking bananas. Triploid cultivars derived solely from M. acuminata are examples of "dessert bananas", whereas triploid cultivars derived from the hybrid between M. acuminata and M. balbinosa (in particular the plantain subgroup of the AAB Group) are "plantains". Small farmers in Colombia grow a much wider range of cultivars than large commercial plantations. A study of these cultivars showed that they could be placed into at least three groups based on their characteristics: dessert bananas, non-plantain cooking bananas, and plantains, although there were overlaps between dessert and cooking bananas.
In Southeast Asia – the center of diversity for bananas, both wild and cultivated – the distinction between "bananas" and "plantains" does not work, according to Valmayor et al. Many bananas are used both raw and cooked. There are starchy cooking bananas which are smaller than those eaten raw. The range of colors, sizes and shapes is far wider than in those grown or sold in Africa, Europe or the Americas.[35] Southeast Asian languages do not make the distinction between "bananas" and "plantains" that is made in English (and Spanish). Thus both Cavendish cultivars, the classic yellow dessert bananas, and Saba cultivars, used mainly for cooking, are called pisang in Malaysia and Indonesia, kluai in Thailand and chuoi in Vietnam. Fe'i bananas, grown and eaten in the islands of the Pacific, are derived from entirely different wild species than traditional bananas and plantains. Most Fe'i bananas are cooked, but Karat bananas, which are short and squat with bright red skins, very different from the usual yellow dessert bananas, are eaten raw.
In summary, in commerce in Europe and the Americas (although not in small-scale cultivation), it is possible to distinguish between "bananas", which are eaten raw, and "plantains", which are cooked. In other regions of the world, particularly India, Southeast Asia and the islands of the Pacific, there are many more kinds of banana and the two-fold distinction is not useful and not made in local languages. Plantains are one of many kinds of cooking bananas, which are not always distinct from dessert bananas.
HISTORICAL CULTIVATION
Farmers in Southeast Asia and Papua New Guinea first domesticated bananas. Recent archaeological and palaeoenvironmental evidence at Kuk Swamp in the Western Highlands Province of Papua New Guinea suggests that banana cultivation there goes back to at least 5000 BCE, and possibly to 8000 BCE. It is likely that other species were later and independently domesticated elsewhere in Southeast Asia. Southeast Asia is the region of primary diversity of the banana. Areas of secondary diversity are found in Africa, indicating a long history of banana cultivation in the region.
Phytolith discoveries in Cameroon dating to the first millennium BCE triggered an as yet unresolved debate about the date of first cultivation in Africa. There is linguistic evidence that bananas were known in Madagascar around that time. The earliest prior evidence indicates that cultivation dates to no earlier than late 6th century CE. It is likely, however, that bananas were brought at least to Madagascar if not to the East African coast during the phase of Malagasy colonization of the island from South East Asia c. 400 CE.
The banana may also have been present in isolated locations elsewhere in the Middle East on the eve of Islam. The spread of Islam was followed by far-reaching diffusion. There are numerous references to it in Islamic texts (such as poems and hadiths) beginning in the 9th century. By the 10th century the banana appears in texts from Palestine and Egypt. From there it diffused into North Africa and Muslim Iberia. During the medieval ages, bananas from Granada were considered among the best in the Arab world. In 650, Islamic conquerors brought the banana to Palestine. Today, banana consumption increases significantly in Islamic countries during Ramadan, the month of daylight fasting.
Bananas were certainly grown in the Christian Kingdom of Cyprus by the late medieval period. Writing in 1458, the Italian traveller and writer Gabriele Capodilista wrote favourably of the extensive farm produce of the estates at Episkopi, near modern day Limassol, including the region's banana plantations.
Bananas were introduced to the Americas by Portuguese sailors who brought the fruits from West Africa in the 16th century.
Many wild banana species as well as cultivars exist in extraordinary diversity in New Guinea, Malaysia, Indonesia, China, and the Philippines.
There are fuzzy bananas whose skins are bubblegum pink; green-and-white striped bananas with pulp the color of orange sherbet; bananas that, when cooked, taste like strawberries. The Double Mahoi plant can produce two bunches at once. The Chinese name of the aromatic Go San Heong banana means 'You can smell it from the next mountain.' The fingers on one banana plant grow fused; another produces bunches of a thousand fingers, each only an inch long.
—Mike Peed, The New Yorker
In 1999 archaeologists in London discovered what they believed to be the oldest banana in the UK, in a Tudor rubbish tip.
PLANTATION CULTIVATION IN THE CARIBBEAN,
CENTRAL & SOUTH AMERICA
In the 15th and 16th centuries, Portuguese colonists started banana plantations in the Atlantic Islands, Brazil, and western Africa. North Americans began consuming bananas on a small scale at very high prices shortly after the Civil War, though it was only in the 1880s that it became more widespread. As late as the Victorian Era, bananas were not widely known in Europe, although they were available. Jules Verne introduces bananas to his readers with detailed descriptions in Around the World in Eighty Days (1872).
The earliest modern plantations originated in Jamaica and the related Western Caribbean Zone, including most of Central America. It involved the combination of modern transportation networks of steamships and railroads with the development of refrigeration that allowed bananas to have more time between harvesting and ripening. North America shippers like Lorenzo Dow Baker and Andrew Preston, the founders of the Boston Fruit Company started this process in the 1870s, but railroad builders like Minor C Keith also participated, eventually culminating in the multi-national giant corporations like today's Chiquita Brands International and Dole. These companies were monopolistic, vertically integrated (meaning they controlled growing, processing, shipping and marketing) and usually used political manipulation to build enclave economies (economies that were internally self-sufficient, virtually tax exempt, and export oriented that contribute very little to the host economy). Their political maneuvers, which gave rise to the term Banana republic for states like Honduras and Guatemala, included working with local elites and their rivalries to influence politics or playing the international interests of the United States, especially during the Cold War, to keep the political climate favorable to their interests.
PEASANT CULTIVATION FOR EXPORT IN THE CARIBBEAN
The vast majority of the world's bananas today are cultivated for family consumption or for sale on local markets. India is the world leader in this sort of production, but many other Asian and African countries where climate and soil conditions allow cultivation also host large populations of banana growers who sell at least some of their crop.
There are peasant sector banana growers who produce for the world market in the Caribbean, however. The Windward Islands are notable for the growing, largely of Cavendish bananas, for an international market, generally in Europe but also in North America. In the Caribbean, and especially in Dominica where this sort of cultivation is widespread, holdings are in the 1–2 acre range. In many cases the farmer earns additional money from other crops, from engaging in labor outside the farm, and from a share of the earnings of relatives living overseas. This style of cultivation often was popular in the islands as bananas required little labor input and brought welcome extra income. Banana crops are vulnerable to destruction by high winds, such as tropical storms or cyclones.
After the signing of the NAFTA agreements in the 1990s, however, the tide turned against peasant producers. Their costs of production were relatively high and the ending of favorable tariff and other supports, especially in the European Economic Community, made it difficult for peasant producers to compete with the bananas grown on large plantations by the well capitalized firms like Chiquita and Dole. Not only did the large companies have access to cheap labor in the areas they worked, but they were better able to afford modern agronomic advances such as fertilization. The "dollar banana" produced by these concerns made the profit margins for peasant bananas unsustainable.
Caribbean countries have sought to redress this problem by providing government supported agronomic services and helping to organize producers' cooperatives. They have also been supporters of the Fair Trade movement which seeks to balance the inequities in the world trade in commodities.
EAST AFRICA
Most farms supply local consumption. Cooking bananas represent a major food source and a major income source for smallhold farmers. In east Africa, highland bananas are of greatest importance as a staple food crop. In countries such as Uganda, Burundi, and Rwanda per capita consumption has been estimated at 45 kilograms per year, the highest in the world.
MODERN CULTIVATION
All widely cultivated bananas today descend from the two wild bananas Musa acuminata and Musa balbisiana. While the original wild bananas contained large seeds, diploid or polyploid cultivars (some being hybrids) with tiny seeds are preferred for human raw fruit consumption. These are propagated asexually from offshoots. The plant is allowed to produce two shoots at a time; a larger one for immediate fruiting and a smaller "sucker" or "follower" to produce fruit in 6–8 months. The life of a banana plantation is 25 years or longer, during which time the individual stools or planting sites may move slightly from their original positions as lateral rhizome formation dictates.
Cultivated bananas are parthenocarpic, i.e. the flesh of the fruit swells and ripens without its seeds being fertilized and developing. Lacking viable seeds, propagation typically involves farmers removing and transplanting part of the underground stem (called a corm). Usually this is done by carefully removing a sucker (a vertical shoot that develops from the base of the banana pseudostem) with some roots intact. However, small sympodial corms, representing not yet elongated suckers, are easier to transplant and can be left out of the ground for up to two weeks; they require minimal care and can be shipped in bulk.It is not necessary to include the corm or root structure to propagate bananas; severed suckers without root material can be propagated in damp sand, although this takes somewhat longer.In some countries, commercial propagation occurs by means of tissue culture. This method is preferred since it ensures disease-free planting material. When using vegetative parts such as suckers for propagation, there is a risk of transmitting diseases (especially the devastating Panama disease).As a non-seasonal crop, bananas are available fresh year-round.
CAVENDISH
In global commerce in 2009, by far the most important cultivars belonged to the triploid AAA group of Musa acuminata, commonly referred to as Cavendish group bananas. They accounted for the majority of banana exports, despite only coming into existence in 1836. The cultivars Dwarf Cavendish and Grand Nain (Chiquita Banana) gained popularity in the 1950s after the previous mass-produced cultivar, Gros Michel (also an AAA group cultivar), became commercially unviable due to Panama disease, caused by the fungus Fusarium oxysporum which attacks the roots of the banana plant. Cavendish cultivars are resistant to the Panama Disease but in 2013 there were fears that the Black Sigatoka fungus would in turn make Cavendish bananas unviable.
Ease of transport and shelf life rather than superior taste make the Dwarf Cavendish the main export banana.
Even though it is no longer viable for large scale cultivation, Gros Michel is not extinct and is still grown in areas where Panama disease is not found. Likewise, Dwarf Cavendish and Grand Nain are in no danger of extinction, but they may leave supermarket shelves if disease makes it impossible to supply the global market. It is unclear if any existing cultivar can replace Cavendish bananas, so various hybridisation and genetic engineering programs are attempting to create a disease-resistant, mass-market banana.
RIPENING
Export bananas are picked green, and ripen in special rooms upon arrival in the destination country. These rooms are air-tight and filled with ethylene gas to induce ripening. The vivid yellow color consumers normally associate with supermarket bananas is, in fact, caused by the artificial ripening process. Flavor and texture are also affected by ripening temperature. Bananas are refrigerated to between 13.5 and 15 °C during transport. At lower temperatures, ripening permanently stalls, and the bananas turn gray as cell walls break down. The skin of ripe bananas quickly blackens in the 4 °C environment of a domestic refrigerator, although the fruit inside remains unaffected.
"Tree-ripened" Cavendish bananas have a greenish-yellow appearance which changes to a brownish-yellow as they ripen further. Although both flavor and texture of tree-ripened bananas is generally regarded as superior to any type of green-picked fruit, this reduces shelf life to only 7–10 days.Bananas can be ordered by the retailer "ungassed" (i.e. not treated with ethylene), and may show up at the supermarket fully green. Guineos verdes (green bananas) that have not been gassed will never fully ripen before becoming rotten. Instead of fresh eating, these bananas are best suited to cooking, as seen in Mexican culinary dishes.A 2008 study reported that ripe bananas fluoresce when exposed to ultraviolet light. This property is attributed to the degradation of chlorophyll leading to the accumulation of a fluorescent product in the skin of the fruit. The chlorophyll breakdown product is stabilized by a propionate ester group. Banana-plant leaves also fluoresce in the same way. Green bananas do not fluoresce. The study suggested that this allows animals which can see light in the ultraviolet spectrum (tetrachromats and pentachromats) to more easily detect ripened bananas.
STORAGE & TRANSPORT
Bananas must be transported over long distances from the tropics to world markets. To obtain maximum shelf life, harvest comes before the fruit is mature. The fruit requires careful handling, rapid transport to ports, cooling, and refrigerated shipping. The goal is to prevent the bananas from producing their natural ripening agent, ethylene. This technology allows storage and transport for 3–4 weeks at 13 °C. On arrival, bananas are held at about 17 °C and treated with a low concentration of ethylene. After a few days, the fruit begins to ripen and is distributed for final sale. Unripe bananas can not be held in home refrigerators because they suffer from the cold. Ripe bananas can be held for a few days at home. If bananas are too green, they can be put in a brown paper bag with an apple or tomato overnight to speed up the ripening process.
Carbon dioxide (which bananas produce) and ethylene absorbents extend fruit life even at high temperatures. This effect can be exploited by packing banana in a polyethylene bag and including an ethylene absorbent, e.g., potassium permanganate, on an inert carrier. The bag is then sealed with a band or string. This treatment has been shown to more than double lifespans up to 3–4 weeks without the need for refrigeration.
FRUIT
Bananas are a staple starch for many tropical populations. Depending upon cultivar and ripeness, the flesh can vary in taste from starchy to sweet, and texture from firm to mushy. Both the skin and inner part can be eaten raw or cooked. The primary component of the aroma of fresh bananas is isoamyl acetate (also known as banana oil), which, along with several other compounds such as butyl acetate and isobutyl acetate, is a significant contributor to banana flavor.
During the ripening process, bananas produce the gas ethylene, which acts as a plant hormone and indirectly affects the flavor. Among other things, ethylene stimulates the formation of amylase, an enzyme that breaks down starch into sugar, influencing the taste of bananas. The greener, less ripe bananas contain higher levels of starch and, consequently, have a "starchier" taste. On the other hand, yellow bananas taste sweeter due to higher sugar concentrations. Furthermore, ethylene signals the production of pectinase, an enzyme which breaks down the pectin between the cells of the banana, causing the banana to soften as it ripens.
Bananas are eaten deep fried, baked in their skin in a split bamboo, or steamed in glutinous rice wrapped in a banana leaf. Bananas can be made into jam. Banana pancakes are popular amongst backpackers and other travelers in South Asia and Southeast Asia. This has elicited the expression Banana Pancake Trail for those places in Asia that cater to this group of travelers. Banana chips are a snack produced from sliced dehydrated or fried banana or plantain, which have a dark brown color and an intense banana taste. Dried bananas are also ground to make banana flour. Extracting juice is difficult, because when a banana is compressed, it simply turns to pulp. Bananas feature prominently in Philippine cuisine, being part of traditional dishes and desserts like maruya, turrón, and halo-halo or saba con yelo. Most of these dishes use the Saba or Cardaba banana cultivar. Bananas are also commonly used in cuisine in the South-Indian state of Kerala, where they are steamed (puzhungiyathu), made into curries, fried into chips (upperi) or fried in batter (pazhampori). Pisang goreng, bananas fried with batter similar to the Filipino maruya or Kerala pazhampori, is a popular dessert in Malaysia, Singapore, and Indonesia. A similar dish is known in the United Kingdom and United States as banana fritters.
Plantains are used in various stews and curries or cooked, baked or mashed in much the same way as potatoes, such as the Pazham Pachadi prepared in Kerala.
Seeded bananas (Musa balbisiana), one of the forerunners of the common domesticated banana, are sold in markets in Indonesia.
FLOWER
Banana hearts are used as a vegetable in South Asian and Southeast Asian cuisine, either raw or steamed with dips or cooked in soups, curries and fried foods. The flavor resembles that of artichoke. As with artichokes, both the fleshy part of the bracts and the heart are edible.
LEAVES
Banana leaves are large, flexible, and waterproof. They are often used as ecologically friendly disposable food containers or as "plates" in South Asia and several Southeast Asian countries. In Indonesian cuisine, banana leaf is employed in cooking method called pepes and botok; the banana leaf packages containing food ingredients and spices are cooked on steam, in boiled water or grilled on charcoal. In the South Indian states of Tamil Nadu, Karnataka, Andhra Pradesh and Kerala in every occasion the food must be served in a banana leaf and as a part of the food a banana is served. Steamed with dishes they impart a subtle sweet flavor. They often serve as a wrapping for grilling food. The leaves contain the juices, protect food from burning and add a subtle flavor. In Tamil Nadu (India) leaves are fully dried and used as packing material for food stuffs and also making cups to hold liquid foods. In Central American countries, banana leaves are often used as wrappers for tamales.
TRUNK
The tender core of the banana plant's trunk is also used in South Asian and Southeast Asian cuisine, and notably in the Burmese dish mohinga.
FIBER
TEXTILES
The banana plant has long been a source of fiber for high quality textiles. In Japan, banana cultivation for clothing and household use dates back to at least the 13th century. In the Japanese system, leaves and shoots are cut from the plant periodically to ensure softness. Harvested shoots are first boiled in lye to prepare fibers for yarn-making. These banana shoots produce fibers of varying degrees of softness, yielding yarns and textiles with differing qualities for specific uses. For example, the outermost fibers of the shoots are the coarsest, and are suitable for tablecloths, while the softest innermost fibers are desirable for kimono and kamishimo. This traditional Japanese cloth-making process requires many steps, all performed by hand.
In a Nepalese system the trunk is harvested instead, and small pieces are subjected to a softening process, mechanical fiber extraction, bleaching and drying. After that, the fibers are sent to the Kathmandu Valley for use in rugs with a silk-like texture. These banana fiber rugs are woven by traditional Nepalese hand-knotting methods, and are sold RugMark certified.
In South Indian state of Tamil Nadu after harvesting for fruit the trunk (outer layer of the shoot) is made into fine thread used in making of flower garlands instead of thread.
PAPER
Banana fiber is used in the production of banana paper. Banana paper is made from two different parts: the bark of the banana plant, mainly used for artistic purposes, or from the fibers of the stem and non-usable fruits. The paper is either hand-made or by industrial process.
