Abstract
Uniconazole applied to cotyledons inhibited the flowering response in Pharbitis nil. The application of gibberellin A1 (GA1) to cotyledons overcame the effect of uniconazole and restored the flowering response. The transport of GA1 from cotyledons to plumules was confirmed by GC-MS analyses. The results indicate that GAs transported from cotyledons are concerned with regulating the endogenous level of GAs in plumules.
