Effect of 1-MCP on post-harvest physiology and quality of summer squash
In order to discuss the effect of 1-methylcyclopropene treatment on index of physiology and biochemistry of summer squash on postharvest,the experiments were made by three treatments:control,5 μL/L 1-MCP treatment,10 μL/L 1-MCP treatment.All the treatments were treated for 20 h at room temperature(20 ℃) followed by storage at 20 ℃.The results showed that 1-MCP treatment could restrain the respiration rate,postpone the appearing time of respiration peak,delay the decline of Vitamin C and protein content of summer squash.In addition,the raise of cell membrane permeability was inhabited,the SOD and CAT activities are preserved at a high level.At the same time,it was found that the effect of 10 μL/L content was the best.
