Abstract
The present study was carried out during the two successive seasons of 2014 and 2015 on five years old Wonderfulpomegranate cultivar (Punica granatum, L) in order to investigate the effect of fruit bagging, spraying with lime milk,super nano, CaCO3, vitamin C and kaolin, as well as, nitrogen and potassium fertilization on the fruit quality especiallythe incidence of sunburn. The obtained results showed that all treatments significantly affected fruit sunburn percentageand number of sunburned fruits, especially bagging, super nano and kaolin sprays. A significant decrease in the sunburnseverity occurred with the bagging and super nano sprays treatments. All different treatments increased fruit TSS andvitamin C. Spraying super nano on the fruit was the best in increasing TSS/acidity ratio. Spraying lime milk or super nanoon the tree and were the best in increasing fruit anthocyanin content.
