Abstract Effects of the application of gibberellin A3 (GA3) on sprouting of rhizomes and germination of seeds were tested in five species of the genus Dioscorea which are considered to be Tertiary relicts growing disjunctively in the Appalachians, the Balkans, and the Caucasus. Applied GA3 at higher than 1 micro;M markedly inhibited sprouting of rhizomes of all species. However, inhibition of seed germination of these species by GA3 application was not observed. It is hypothesized that before disjunction in the Tertiary period GA-induced dormancy probably prevailed in rhizomes of all members of the genus Dioscorea.
