The experiment was carried out at Post-harvest Laboratory, Department of Horticulture, College of Agriculture, CCSHAU, Hisar to find out effect of post-harvest chemicals on physiological parameters of aonla under ambient storage conditions. The fruits were treated with different concentration of GA₃ (400, 500 and 600 ppm), Ca(NO₃)₂ (1.0, 2.0 and 3.0%), KMnO₄ (1000, 2000 and 3000 mg) and bael leaf extract (2.0, 3.0 and 4.0%) and packed in perforated polythene bags and stored at ambient temperature. The physiological changes were faster in untreated fruits (control). Post-harvest treatment with 1.0% Ca(NO₃)₂, followed by 600 ppm GA₃ were recorded lower physiological loss in weight, moisture and decay loss throughout the storage period. The maximum fruit firmness and specific gravity were observed in calcium nitrate 1.0% treated fruits. Among treatments, fruits treated with GA₃ 600 ppm had showed better colour retention.
