Jatropha hybrid - Stem (110 DAS)

Interspecific hybrid (Jatropha scaposa x Jatropha curcas). At 110 days after sowing, only the basal part of the stem is woody (like in J. curcas) and very thick, unlike any of the parents. The other part of the stem stays green and herbaceous, like in J. scaposa. The petioles are thick, like in J. scaposa. The stem is single, unbranched, like in J. scaposa and unlike J. curcas where 1 up to 3 branches arise from the axils of the cotyledonary leaves and the first real leaf.
