Gibberellin-Induced Inhibition of Bud Development in Some Species of Prunus

Development of both floral and vegetative buds was inhibited by application of gibberellin to branches of Prunus species. The development of the lateral meristem was blocked, in general, through inhibition of mitosis, while, concurrently, the growth of certain other plant organs was stimulated in some cases. That higher dosages were required to block vegetattive than floral bud growth suggests that gibberellin also exerts the more specific effect of inhibiting floral initiation.
