Abstract : Kesar, a commercial mango cultivar from western India, was studied for assessing the storage life during 2004-05. The fruits were harvested at defined physiological maturity stage from well-managed commercial mango orchard near Aurangabad. The fruits were washed adequately and treated with gibberellic acid (50, 100 and 150 ppm) in combination with calcium chloride (8%) and fungicide. The fruits of various treatments were loosely packed in CFB boxes and stored at ambient temperature to assess postharvest storage life. The total soluble solids (TSS) and total sugars reported increasing trend, whereas titratable acidity, ascorbic acid and physiological loss in weight (PLW) were found linearly decreasing during the ripening. The fruits treated with 100 ppm GA3 and 8% CaCl2 were observed superior in respect of pre-ripening quality attributes. The treatment retarded the physicochemical changes feasible for manifestation of ripening quality features and certainly helped considerably in delaying the ripening. This has profoundly notified the extended storage life of Kesar mango. The observations on physicochemical changes and sensorial quality parameters were used as ripening and storage life monitoring indices.
