IntroductionIntroductionMany special ways of training trees have been proposed over the past century and before (DeJong et al., 1999). Some systems are specific to dwarf trees, some are designed for better light distribution, some for ease of harvest, some for better support for crop, some for protection from wind, some for better fruit quality, and still others for better spray coverage to control pests. For the grower, choice of a system should be based on general cropping efficiency balanced with the cost of establishing and maintaining it. The success of a system in one area does not ensure its success in a different climate or economic situation (Westwood, 1995).

Pruning of Deciduous Fruit TreesPruning of Deciduous Fruit Trees

The kind of fruit is important in determining the best pruning method because of the different flowering habits and the different ultimate fruit size at harvest.

Fruits such as peach, that initiate their flowers on current shoots and that have naturally large fruits respond better to heavy pruning than those that set flowers on older spurs (apple and pear) and have naturally small fruits (cherry).

ConclusionConclusion

In general, It could be concluded that V and Y training systems gave the greatest LAI, light interception and yield efficiency as compared with SS, CL and inter-stem CL training systems. Density was the predominant factor affecting tree growth, LA, light interception and fruit yield years regardless of training system.
