Method of pruning apple tree crown size and increase in photosynthesis productivity

Abstract

The most important condition for increasing the productivity of fruit trees in intensive orchards is the optimal and efficient use of solar radiation, as well as an increase in leaf surface area. For apple trees, the size of the leaf surface, the illumination of the tree crowns and the increase in the productivity of photosynthesis are often determined by the combination of variety-rootstock combinations, the method of pruning and forming trees, and the size of the tree crowns. It has been established that the most effective rejuvenating and normalizing pruning is the shortening of fruit-bearing branches by 8-16 fruit buds.
