Inhibition of Flower Bud Initiation and Development in Apple by Defoliation, Gibberellic Acid and Crop Load Manipulation
… crop years. The GA4+7 treatments suppressed return bloom of both spur and lateral flowers more than the GA3 treatments. The effectiveness of GA declined with delayed application. Both GA treatments reduced lateral flowering the most on the basal 1/3 of the shoot. In a four year study, apple …
