Effect of 1-methylcyclopropene treatments on physiological and chemical characteristics of cucumber fruits suffered mechanical damage during post-harvest

Cucumber will be mechanical damaged inevitably in the process of storage and transportation during postharvest. In this experiment, cucumber fruits were pretreatment with 1-methylcyclopropene (1-MCP) at 1ppm to research the effects of 1-MCP on its physiological and chemical characteristics. The results showed that the respiration rate, electrolyte leakage, malondialdehyde (MDA) amounts of cucumber fruits with 1-MCP treatment were significant difference compared to the control. Cucumber fruits treated with 1-MCP could keep the activities of the catalase (CAT) , peroxidase (POD) , ascorbate peroxidase (APX) , phenylalanine aminolyase (PAL) in mechanical damage cucumber fruits, conducive to maintain the quality of the mechanical damage cucumber fruits. The experiment results showed that cucumber fruits treated with 1-MCP could relievethe injury which caused by mechanical damage and keep its character of quality.
