Question
How do Dioscorea reproduce vegetatively?
Solution
Vegetative reproduction in stem From Unit 3 of class XI (Vegetative morphology) you are familiar with the structure of various underground stem and sub aerial stem modifications. These include rhizome (Musa paradisiaca, Zingiber officinale, and Curcuma longa); corm (Amorphophallus and Colocasia); tuber (Solanum tuberosum); bulb(Allium cepa and Lillium) runner (Centella Asiatica); stolon (Mentha, and Fragaria); offset (Pistia, and Eichhornia); sucker (Chrysanthemum) and bulbils (Dioscorea and Agave). The axillary buds from the nodes of the rhizome and the eyes of the tuber give rise to new plants.
