Abstract:
An experiment was conducted to investigate the effect of pre-harvest treatments on shelf-life and quality of mango cv. Amrapali fruits during storage at ambient conditions (25 ± 5°C; 65 ± 5% RH). Mango trees were sprayed with 0.5, 1.0 and 1.5 % CaCl₂ and 25, 50 and 75 ppm GA₃ at 20 and 10 days before harvest (DBH) with the objective of extending the shelf-life of fruits and delay the ripening process. Fruits trees sprayed with 75 ppm GA₃ at 20 DBH (T₃) and 1.50% CaCl₂ at 20 DBH(T₆) took more number of days for ripening (16.3 and 16.0 days) while it was least in control (8.3 days). Fruits sprayed with GA₃ @75ppm at 20 DBH showed shelf life upto 21.0 days followed by 1.50% CaCl₂ at 20 DBH (20.8days) as against 11.3 days of control trees. Spray of 75 ppm GA₃ at 20 DBH and spray of 1.50% CaCl₂ at 20DBH significantly improved the physico-chemical parameters and organoleptic evaluation of mango fruits compared to control.
