Influence of Training Systems on Leaf Mineral Contents, Growth, Yield and Fruit Quality of “Anna” Apple Trees

The influence of two training systems (tiller, and open central leader) on leaf mineral contents, growth, fruit set, yield, and fruit quality of "Anna" apples cultivar was estimated in the experiment conducted during two successive seasons at private orchard located Cairo Alexandria desert road about 80 Km from Cairo. Results indicated that, tiller training system significantly increased leaf Nitrogen, and Potassium contents. Moreover, shoots length, diameter, and leaf area were increased significantly under tiller training system as compared with open central leader training system (control). Also, fruit set, yield, and fruit quality increased significantly with tiller training system compared with control. Present study can lead to conclude that tiller training system significantly affect growth, yield, and fruit quality, and it is recommended to apply cultural practices for improving irradiance conditions which consequently enhance production in apple orchards.
