Abstract
One early treatment (late May) with 25 ppm gibberellic acid (GA3) strongly depressed summer and fall bloom and resulting off-season fruits of ‘Temple’ orange (Citrus reticulata Blanco × C. sinensis (L.) osbeck). A late June treatment failed to repress and even tended to increase the number of off-season fruits. A repeated treatment at both dates, had a smaller effect than a single early treatment. A possible effect of a late GA application on the persistence of off-season fruitlets is suggested. Girdling of a part of scaffold branches gave a response similar to that of the early GA treatment.
