1-MCP,an inhibitor for ethylene reaction,was applied to mango fruit for 24 h after harvest at room temperature.1-MCP gas concentration was 0.25 μL/L,0.50 μL/L,1.0 μL/L,respectively.Quality retention of the fruit was assessed by measuring yellow index transfers,respiration intensity,ethylene production,malondialdehyde (MDA),and the activities of lipoxygenase (LOX) and POD.The result showed that the 0.50μl/L1-MCPtreatment significantly inhibited ethylene production,delayed the ethylene peak and better maintained the transfers yellow index and respiration intensity.The 1-MCP treatment retarded the increase accumulation of MDA,and improved the activities of POD and LOX during storage.These results suggested that 0.50 μL/L 1-MCP treatments had the beneficial effect on decreasing the ethylene production,improving storage quality and delaying ripening during the storage of mango fruits.
