Abstract : Ripening is a genetically programmed stage of physiological development overlapping with senescence. Studies on hastening the onset of ripening in Kesar mango was undertaken during 2 consecutive seasons. The fruits were harvested at defined physiological maturity from a well-managed commercial mango orchard near Aurangabad (India). The sorted fruits were washed properly and treated with 2 different concentrations of ethrel solution in combination with fungicide. The ripening of fruits at recommended temperature (22±1°C) and ambient temperature (AT) was evaluated for quality attributes. The ripening induced physicochemical changes were assessed at a frequent interval of time to notify sensorial quality parameters. The total soluble solids, total sugars and reducing sugars exhibited increasing trend, whereas titratable acidity, ascorbic acid and physiological loss in weight decreased during the course of ripening. The manifestation of ripening quantity and quality attributes was more prominent at AT compared to the standard recommended temperature. Three days enhancement logging period for desired and uniform ripening quality attributes was observed with 500 and 1000 ppm ethrel concentration at similar temperature. The data on various ripening induced changes were recorded and correlated to expedite ripening quality attributes.
