Flower bud formation in various Prunus species can be curtailed or completely prevented with use of gibberellic acid—depending upon the concentration used. Many of the important tree fruit crops grown in California, including peach, plum, cherry, and apricot belong to this genus. These trials indicated that gibberellic acid sprays may be useful in reducing or eliminating hand thinning and in controlling crop levels in cling peaches.
