Abstract
The current research was carried out during two successive seasons (2015 and 2016) to study the effect of some pre-harvest treatments on ”Wonderful” pomegranate yield and fruit quality. This study conducted on 15 years old pomegranate trees grown in a sandy soil, drip irrigation system and planned at 3.5{u00D7}6m in a private orchard. The pomegranate trees treated with, calcium chloride CaCl₂ ̄at 2, 3 and 4%, potassium oxide K₂O at 1.5, 2 and 3%, mix of mineral compounds at 0.5, 1 and 1.5%, humic acid and mixture of amino acids were prepared at 0.5, 1.0 and 1.5 % and 0.3, 0.5 and 1.0 %, respectively and sprayed directly on the vegetative growth, in addition to, control treatment which only sprayed with water. All treatments were applied as foliar spraying twice/year (two and eight weeks after full bloom). Fruits were picked at mid-September in both seasons. At full ripe stage, fruits from each treatment were picked in the early morning, and immediately transported to the laboratory, these fruits were picked and bagged in carton boxes and stored at cold temperature (5{u00BA}C with 90-95% RH). Three replicates (one box for each replicate contain 30 fruits) from each treatment were used to study the physical and chemical properties of the stored fruits. Each 15 days a fruit sample was taken. Results revealed that there is clear difference between treatments where CaCl₂ treatment at 4% gave the highest fruit yield, fruit number, fruit weight, fruit length, fruit diameter, fruit grain and fruit juice in the two seasons before cold storage period in comparsion with control treatment. On the other hand, potassium oxide, humic acid, amino acids and mixture of mineral compounds treatments doen{u2019}st show any significant differences in comparsion with control treatment. During cold storage period, CaCl₂ at 4% treatment gave {u0369} the lowest values of fruit weight loss, decay percentage and fruit acidity
