Abstract : Mango cv. Tommy Atkins fruits were harvested at stage 2 of maturity and treated with gaseous 1-methylcyclopropene (1-MCP; 100 or 500 nl/litre) at room temperature (25°C) in sealed chambers for 12 h. Then, the fruits were stored for 25 days at 11.5±1.7°C and 86.1±8.4% RH, followed by 7 days at 25.4±0.2°C and 97.6±1.2% RH. The effects of 1-MCP and modified atmosphere (MA), alone or in combination, on the ripening of fruits were investigated. The lowest respiration rates were observed in fruits treated with 100 nl 1-MCP/litre, without MA, and in those treated with 500 nl 1-MCP/litre and MA. 1-MCP kept the fruits more acid, with higher vitamin C contents, especially at 100 nl/litre. 1-MCP had no effect on total soluble solids. MA by film alone decreased soluble solids accumulation. The use of 1-MCP alone would represent lower postharvest costs, higher number of treated fruits and less postharvest management steps.
