Effect of preharvest application of GA3 on postharvest behaviour of mango fruits.

GA3 was applied as a foliar spray to the mango cultivar Dashehari at 100, 200, 300 or 400 mg/litre after fruit set in 1988 and 1989, followed by another spray 10 days later. GA3 retarded the ripening of mango fruits for up to 6 days of storage under ambient temperatures between 36 plus or minus 2 and 40 plus or minus 3 deg C. With increasing GA3 concentrations, postharvest ripening during the first 6 days was delayed significantly. Fruits that received more than or equal to 200 mg GA3/litre, exhibited less total soluble solids (TSS), a lower TSS/acid ratio, less total carotenoids, and lower amylase and peroxidase activity at harvest. Total acidity, ascorbic acid and total chlorophyll in peel were significantly higher in these fruits.
