Abstract : Studies with the mango cultivars Dashehari, Amrapali and Rataul indicated that during postharvest ripening of fruits at room temperature (26°C), there was considerable variation between cultivars in respiration rate, loss in FW, sugar content and activities of enzymes associated with ripening such as pectin methyl esterase [pectinesterase] and polygalacturonase. A rise in climacteric respiration rate coincided with the highest level of sucrose and polygalacturonase activity. The highest rate of respiration was noted in Amrapali and the lowest in Dashehari.
