Abstract : The objective of this work was to evaluate the effect of the 1-MCP in the firmness of mangoes cv. Palmer stored under refrigeration. The mangos were treated with 1-MCP in concentrations of 0, 100 and 150 nl/litre, during 12 h at 22°C. Soon after, they were stored in a cold chamber (10±1°C and 80 to 90% UR), for 35 days. Every 7 days were retired 6 fruits of each treatment for to the following evaluations: firmness, total pectin, percentage of solubilization of pectins, activity of the pectinmethylesterase, polygalacturonase and â-D-galactosidase activities. The treatment with 1-MCP, associated to the refrigeration showed to be efficient in prolonging the useful life of the fruits. The treated fruits with 150 nl/litre presented smaller percentage of pectin solubilization and firmness in the end of the storage, when compared to the other treatments. After 35 days of refrigeration, all fruits were capable for consumption, indicating that other studies should be accomplished increasing the time of storage.
