Abstract: Mulberry was treated with 1-methylcyclo-propene (1-MCP) before storage at 0－2 ℃, and changes in vitamin C, chlorophyll, titratable acid, hardness, respiration intensity and decay during the storage were determined. Results showed that 1-MCP treatment delayed the decline of hardness, vitamin C content and chlorophyll after 48 hours, and titratable acid content even with a slight increase in the beginning. Also, 1-MCP treatment decreased the rate of decay of mulberry. Meanwhile, no obvious decrease in respiration intensity of mulberry was observed. However, no linear correlation between the rate of decay and the concentration of 1-MCP was found, which suggests that there is an optimum 1-MCP concentration for preventing the decay of mulberry.
