Abstract: In order to explore the effects of different treatments on the storage of muskmelon at room temperature,the‘Jinhongbao’muskmelon was used as the experimental material, the effects of preservatives 1-MCP and 1-MCP compound fungicide imazalil treatments on the storage of postharvest muskmelon at room temperature were investigated. The results showed that, the preservation effect of both 1-MCP and 1-MCP compound fungicide treatment was significantly better than the control. The preservation effect of 1-MCP compound fungicide treatment was better than that of 1-MCP treatment in delaying the decline of ascorbic acid and titratable acid contents, reducing decay rate and weight loss rate. In summary, compared with other treatments, 1-MCP compound fungicide treatment had the best preservation effect, which could effectively maintain the quality of melon.
