Effect of Preharvest Application of Some Antioxidants on The Fruit Yield, Quality and Storability of “Manfalouty” Pomegranate Fruits (Punica granatumL.)
Year: 2020
Type: article
Abstract: Pomegranate (Punica granatum L.) is one the most important sub-tropical fruits due to its nutritional, pharmacological and therapeutic values.The aim of this work was to study the effects of some antioxidants, salicylic acid (SA) and ascorbic acid (ASA) on the yield, cracking and quality of fruits at harvest as well as fruit chilling injuries, weight loss % and quality at cold storage and shelf life of "Manfalouty" cultivar.Seven treatments, ASA at 250 or 500 ppm SA at 250 or 500 ppm, ASA+ SA at 250 + 250 or 500 + 500 ppm and control were applied three times (July, August, September).All treatments of SA and / or ASA improved total yield, fruit weight, fruit juice %, TSS and TSS/TA ratio at harvest.In fruits with ASA at 500ppm induced the highest total yield, fruit weight and TSS in both seasons followed by T2 (ASA at 250ppm) at harvest.However, T7 (SA+ASA at 500+500ppm) recorded the highest aril weight % and juice % at harvest for both seasons.All treatments significantly reduced the weight loss and chilling injuries at cold storage and shelf life during both seasons.
