Abstract:
The effect of floral-bud removal at different stages of development on the plant height and on the total number of buds of Petunia was studied. Continuous removal of all the floral buds 2 d before anthesis caused a marked decrease in plant height and also increased the total number of floral buds formed thereafter. At other stages of floral bud development, bud removal had a lesser effect on both phenomena. Moreover, the plants did not respond to bud removal at anthesis.GA3 at 25 ppm applied to plants from which the buds had been removed, promoted stem elongation. The most pronounced effect was on plants from which the buds were removed 2 d before anthesis, but it had no effect on plants from which the buds were removed at anthesis stage.The possible involvement of endogenous growth hormones in the response of Petunia plants to floral-bud removal and to application of GA3 is discussed. © 1985 Annals of Botany Company.
