Effect of post-harvest treatments on shelf life and quality of mango (Mangifera indica L.) cv. Banglora

Abstract

An experiment was conducted at Department of Horticulture, Faculty of Agriculture, Annamalai University during 2013 to investigate the effect of post-harvest treatments on shelf-life and quality of Mango cv. Banglora. Immediately harvested Banglora Mango fruits were collected from Department Orchard. The fruits were stored at ambient conditions (25 ± 5°C; 65 ± 5% RH). Mango were sprayed with 0.5 and 1.5 % CaCl2 and 200 and 300 ppm GA3 and wrapping with News paper and perforated polyethylene bags. The objective of this experiment extending the shelf-life of fruits and delay the ripening process. Fruits sprayed with T2- GA3 200 ppm + wrapping with Newspaper + stored in wooden box took more number of days for ripening, physiological loss, firmness, shelf life, spoilage, TSS, Sugar content, Titrable acidity, Ascorbic acid content. While it was least in control. Fruits sprayed with GA3 @ 200 ppm + wrapping with News paper showed shelf life up to 18.24 days followed by 0.5 % CaCl2 at (14.48 days) as against 8.03 days of control. The physico-chemical parameters evaluation of mango fruits were compared to control.
