Jatropha hybrid - Young plant (65 DAS)
The same young hybrid plant, 65 days after sowing. The first real leaf (unlobed but slightly toothed) is still visible. Leaf margins are completely entire in the older leaves, like in the female parent, Jatropha scaposa. Conclusion: entire leaf margin of older leaf (like in J. scaposa) is dominant over toothed margin of J. curcas. Leaf blades are becoming large, like in J. scaposa (Dominance of large leaf size of J. scaposa). J. scaposa has a clearly thickened rootstock in this phase, but the hybrid plant has an only slightly thickened rootstock (intermediate heritability of root stock formation). In this phase both J. scaposa and the hybrid plant have deeper roots compared to J. curcas. (Dominance of the deep rooting character of J. scaposa). The intensely red pigmented young leaf of the hybrid plant becomes visible now.
