Effect of chemicals on shelf-life of jamun (Syzygium cuminii (L.) Skeels) fruits

Abstract

The present experiment was conducted at Department of Fruit Science and Horticulture Technology, Odisha University of Agriculture and Technology, Bhubaneswar during the year 2018-19 to determine effect of post-harvest treatments of chemicals on shelf-life of jamun fruits cv. CISH J 42. Eight treatments were taken with different chemicals and growth regulator concentrations CaCl2 1%, CaCl2 1.5%, Ca (NO3)2 1%, Ca (NO3)2 1.5%, GA3 50 ppm, GA3 100 ppm followed by perforated polythene packaging, polythene packaging without any chemical and control. This experiment revealed that fruits treated with 1.5% CaCl2 and kept in perforated polyethylene bag, showed reduced in physiological loss in weight (59.364%), spoilage losses (58.333%), maintained the marketable quality (41.667%) and rendering them acceptable up to period of 6 days as compared to control (2 days) when stored under ambient condition.
