The Cuticles of Cox’s Orange Pippin Apples from a Manurial Trial

Abstract

The cuticles of fully-grown Cox fruits from a manurial trial were examined quantitatively. No differences attributable to fertilizer treatment were found in the weights of the cuticles per unit area of surface nor in their major components. This implies that the variations in susceptibility of fruits to storage rots that have been associated with nutritional differences in the manurial trial are not determined by variations in cuticle thickness or composition.
