Gibberellin-induced dormancy in bulbils of Dioscorea.
The sprouting of bulbils of some plants in genus Dioscorea was inhibited by gibberellin (GA) treatment and was promoted by treatment with growth retardants. The results suggest that endogenous GAs in some manner induce and maintain the dormant state in these bulbils.
