Germination ecology of bulbils

Bulbils serve as a means of vegetative reproduction and of dispersal for many plants. Using Chinese yam, Dioscorea polystachya, as a model, Walck et al. examine how bulbil germination is controlled in nature, and find that cold stratification markedly increases root and shoot emergence. They conclude that bulbil germination, being similar to seeds of many temperate plants, adaptively occurs in spring at the beginning of a favourable period for survivorship and growth.
