Abstract
Abstract Simulated pest injury to expanding or fully expanded apple leaves ( Malus domestica Borkh. ‘McIntosh’) by midrib cutting, lamina pricking, or heat injury from ironing reduced net photosynthesis (Pn). Only cutting of the basal half of the midrib of fully expanded leaves reduced transpiration (Tr). Application of gibberellic acid (GA 3 ), and particularly of 6 benzylamino purine (BA), to lamina lesions damaged by pricking, stimulated Pn. This Pn compensation of injured apple leaves mediated by phytohormones may overcome otherwise damaging levels of some pests.
