Abstract
granatum L.) “Wonderful” cultivar since they play a major role in fruit quality. The current study was carried out during the two successive seasons of 2018 and 2019 on ten years old trees grown in sandy soil in a private orchard located at El Bostan, El- Behera Governorate, Egypt. The effect of B, Ca, Zn, Cu and Mn applied at full bloom stage and 6 weeks after full bloom on “Wonderful” trees was studied. The results indicated that the highest value of vegetative growth was obtained from calcium chloride at 4% and zinc sulphate at 0.4% compared with other treatments. Spraying trees with calcium chloride at 4% and zinc sulphate at 0.4% decreased the percentages of fruit drop, cracking, sunburn and increased significantly yield (kg/ tree) and fruit physical parameters such as fruit weight (g), fruit size (cm3) and firmness in comparison to other treatments. Fruit biochemical characteristics such as TSS %, ascorbic acid mg /100ml, Anthocyanin and enhancing coloration have been also positively affected by using this treatment compared with other treatments. It might be recommended that foliar spraying “Wonderful” trees with calcium chloride at 4% and zinc sulphate at 0.4% at full bloom stage and 6 weeks after full bloom where, decreased cracking, sunburn and gave the highest values of yield (kg /tree) and fruit quality under the conditions of the experiment in located at El Bostan, El- Behera Governorate, Egypt.
