Abstract : Mango, being a climacteric fruit, has short shelf-life because of fast ripening followed by senescence accompanied with quality changes and decay loss. To extend the shelf-life, various treatments, i.e. control, 50 and 100 ppm 1-MCP for 24 h and KMnO4 impregnated in chalk sticks, were imposed to mango cv. Lucknow Safeda and stored under ambient condition (30±3°C and 70-80% RH). Various storage attributes were studied at successive stages of storage. In general, cumulative physiological loss in weight, yellowness index, evolution of ethylene and total soluble solids (TSS) increased while firmness, greenness and acidity contents decreased on prolonging the storage period. Among various treatments, 100 ppm 1-MCP was found the most effective for extending the shelf-life for 3 days higher over non-treated fruits, as it delayed ripening, resulted in more firmness, imparted attractive bright yellow colour, palatability and TSS/acid blend coupled with minimum spoilage.
