PHYSIOLOGICAL CHANGES AND SHELF LIFE OF MANGO INFLUENCED BY PREHARVEST BAGGING AND VARIOUS POSTHARVEST TREATMENTS

Abstract

The experiment was carried out at the Department of Horticulture, Sher-e-Bangla Agricultural University, Dhaka. The experiment was laid out in a Completely Randomized Design with three replications. The present research was conducted on the aspect of shelf life and quality of mango through pre-harvest bagging, ten postharvest treatments and two postharvest bagging. Two pre-harvest bagging namely, B: Pre-harvest bagging and B : Without Pre-harvest bagging were assigned to different post-harvest treatments, e.g. T 0 0 : Control, T 1 : Hot water dips, T 2 : Hot water + Bavistin, T Bavistin + Hot water, T 4 : Bavistin dips, T 5 :

Hot water + calcium chloride,

T 6 : calcium chloride + Hot water, T 7 :

calcium chloride dips, T 8 :

3 :

Bavistin + calcium chloride dips and T : calcium chloride + Bavistin and postharvest bagging P: Post-harvest bagging and P : Without Post-harvest bagging were used in the present study. Results revealed that the lowest disease incidence (9.6%, 16.55% and 22.85%) was found in pre-harvest bagging mangoes when treated with Bavistin and hot water dips (BT ) at 9th, 12th and 15th days after harvest respectively where the longest shelf life was observed in BP treatment combinations. The best performance was observed in mangoes when treated with preharvest

bagging, postharvest hot water and bavistin dips and postharvest bagging with perforated poly bags for long term storage quality control, transportation and marketing.
