This explore was conducted to study the effect of NAA (Napthaleneacetic acid) and 2,4,5-T (2,4,5-Trichlorophenoxyacetic acid) on shelf life of apple cv. Red Delicious under 30 days of ambient storage conditions. The growth regulator treatments showed significant effect on shelf life of apple under 30days of ambient storage. Maximum physiological loss in weight (CPLW) (7.53%) was recorded under NAA@ 20ppm and lowest physiological loss in weight (4.33%) was recorded under control. The TSS, total sugars was improved by growth regulators, while as malic acid percentage was lowered compared to untreated fruits. The sugars exhibited an increasing trend with the growth regulators. NAA and 2,4,5-T applied at any timing (4WBAH, 3WBAH, 2WBAH and 1WBAH ) registered a decreasing trend on the ascorbic acid content of treated fruits during the storage period. The effect of NAA on TSS and total sugars was observed more pronounced than 2,4,5-T under 30days of ambient storage. However, NAA promotes more ripening in apples, accelerated starch degradation, increased rot%, decreased fruit firmness and ultimately affected the storage life and fruit quality parameters.
