A laboratory study was conducted to evaluate the effect of GA3 treatment on the shelf-life of chilli cv. Pusa Jwala. Chilli fruits were treated with 0, 50, 100, and 200 ppm GA3 for 10 minutes and air-dried before packing. Data on physiological loss in weight (PLW), fruit decay loss, total chlorophyll and vitamin C content were recorded at 5-day-intervals until day 25. PLW increased with increasing period of storage in all treatments, with GA3 at 200 ppm exhibiting the lowest PLW (20.8% on the 25th day of storage, compared with 33.4% in the control). Decay loss increased with increasing period of storage in all treatments. No decay loss was observed on the 5th day of storage, but the highest decay loss on the 25th day of storage was observed in the control (12.7%) compared with GA3-treated fruits. Total chlorophyll content decreased during storage in all treatments; the highest chlorophyll content on the 25th day of storage (1.6 mg/100g) was recorded with GA3 at 200 ppm. Ascorbic acid content inc
reased with increasing period of storage; the highest (165 mg/100g) being observed with GA3 at 100 and 200 ppm on the 25th day of storage.
