THE INFLUENCE OF SUMMER PRUNING ON THE PHYSIOLOGY AND MORPHOLOGY OF STONE FRUIT TREES
The effects of summer pruning and hedging on vegetative and reproductive growth in stone fruit are reviewed, and related results from our studies on these topics are presented. Summer pruning when compared to dormant pruning is a growth reduction process. The effect is greater the earlier in the season it is accomplished. Summer pruning promotes new shoot development, improves light penetration into the canopy, delays senescence of the shoot and leaves and may reduce winter hardiness depending on the time of pruning, but it has had an inconsistent effect on fruit quality, fruit size and yield in peach. Summer hedging in cherry has been very effective in improving yield and controlling tree size.
