Improving Quality of Wonderful Pomegranate by Using Bagging and Different Agrochemical Treatments

Abstract

The present study was carried out during the two successive seasons of 2014 and 2015 on five years old Wonderful pomegranate cultivar (Punica granatum, L) in order to investigate the effect of fruit bagging, spraying with lime milk, super nano, CaCO 3 , vitamin C and kaolin, as well as, nitrogen and potassium fertilization on the fruit quality especially the incidence of sunburn. The obtained results showed that all treatments significantly affected fruit sunburn percentage and number of sunburned fruits, especially bagging, super nano and kaolin sprays. A significant decrease in the sunburn severity occurred with the bagging and super nano sprays treatments. All different treatments increased fruit TSS and vitamin C. Spraying super nano on the fruit was the best in increasing TSS/acidity ratio. Spraying lime milk or super nano on the tree and were the best in increasing fruit anthocyanin content.

Understanding Phenological Stages of Pomegranates vis-à-vis Flowering and Fruiting Regulation

“…Application of 10 ppm CPPU at flowering followed by a spray of 30 ppm CPPU along with GA3 10 ppm at 21, 42, and 63 days after flowering significantly enhanced fruit set, yield, fruit weight, and sugar contents in 'Bhagwa' (Khemnar et al 2019). Apart from PGRs, the application of silicate and fruit bagging resulted in a harvest of larger fruits with improved color and quality in 'Wonderful' (Samra & Shalan 2013;Abdel-Sattar et al 2017). The positive influence of fruit bagging on fruit color and the nutritional value of arils were also noted by Salama et al (2018), Griñán et al (2019, and Asrey et al (2020).…”
