Influence of pre harvest application of plant bio regulators and chemicals on post harvest quality and shelf life of Mango (Mangifera indica L.)

Abstract

Present study was conducted to know the influence of pre harvest application of plant bio regulators and chemicals on post harvest quality and shelf life of mango cv. Banganpalli at fruit research station, sangareddy, Telangana, India during the 20015-16. Among plant bio regulators maximum shelf life was recorded with pre harvest application of SA (14.16 days) through maintaining the quality as well as fruit physiological parameters viz., total sugars (12.13%), reducing sugars (5.05%), ascorbic acid (54.62 mg/100 gm), fruit firmness (4.66 kg/cm2) and lower PLW% (19.33%) compares to control at ripe stage. Pre harvest application of CPPU has recorded maximum shelf life (13.83 days) by maintaining the higher amounts of total sugars (12.58%) and lower PLW% (19.69%) compare to control and other group of chemicals. Among interaction between plant bio regulators and chemicals maximum shelf life was recorded with pre harvest application of SA along with boron (15.66 days) and retaining the higher amounts of ascorbic acid (60.50 mg/100 gm).
