Abstract : A study was conducted to verify the behaviour of mango cv. Palmer fruits treated with 1-methylcyclopropene (1-MCP) and stored under refrigeration. The treatments comprised 3 levels of 1-MCP (0, 100 and 150 nl/l) and different storage periods (0, 7, 14, 21, 28 and 35 days of cool storage in set up 1, and 0, 7+4, 14+ 4, 21+4, 28+4 and 35 days of cold storage+4 days of room storage in set up 2). The application of 1-MCP to fruits kept under refrigeration decreased the weight and ascorbic acid losses, delaying but not avoiding the ripening. The treatment with 150 nl 1-MCP/l was not more efficient than that with 100 nl/l in terms of the chemical characteristics. The increased weight loss of fruits stored under environmental conditions promoted expressive shriveling and loss of quality, on the basis of the analyses of soluble solids, soluble sugars and titratable acidity.
