Abstract
The present investigation was carried out at PG laboratory in College of Horticulture, Rajendranagar during 2016-2017 and 2017-2018. The experiment was carried out in Completely Randomized Design with three replications. The physical parameters like physiological loss in weight (PLW), number of days for ripening, firmness, ripening percentage, shelf life, and spoilage were estimated. PLW, firmness and spoilage were estimated at 3 days interval during ripening. The data on physical parameters showed that there was significant influence of post harvest application of antioxidants and polyamines on shelf-life of sapota. Fruits treated with BA @ 100 ppm (T2) recorded lower PLW (17.76%), maximum number of days for ripening (8.50 days), and minimum spoilage where as shelf life (12.17 days) and firmness (1.95 kg cm-2), were higher in BA @ 100 ppm (T2) treated fruits during both the years and in pooled data respectively.
