Abstract: 【Objective】To study the effect of 1-Methylcyclopropene(1-MCP) on postharvest low temperature storage quality of Xinfengmilu peach fruit.【Methods】At low temperature of(1.0±0.5) ℃,four 1-MCP treatments,0(CK),0.5,1.0,and 1.5 μL/L were set up to analyse the effect of 1-MCP on Xinfengmilu peach fruit postharvest storage fruit firmness,soluble solid content,respiratory rate,titratable acid content,sound fruit rate,weight loss rate using Xinfengmilu peach fruit as experiment material.【Results】During low temperature storage,the decline rate of Xinfengmilu fruit firmness of 0.5 μL/L 1-MCP treatment was relatively slow,and maintained at high level after 20 d and 25 d of postharvest storage,significantly higher than 1.0 μL/L and 1.5 μL/L 1-MCP treatment(P<0.05). On the 25 d of storage,the titratable acid content of 0.5 μL/L 1-MCP treatment was the highest at 0.59%,extremely significantly higher than CK(P<0.01),and significantly higher than 1.0 μL/L and 1.5 μL/L 1-MCP treatment(P<0.05). The respiratory rate change of CK was faster than the three 1-MCP treatments,and the activity was high. The respiratory rate of CK reached the highest on the 10th day of storage,at 81.23 mg/(kg·h). After 10 d storage,the fruit weight loss rate of 0.5 μL/L 1-MCP treatment was significantly lower (P<0.05) than 1.0 μL/L and 1.5 μL/L 1-MCP treatment.【Conclusion】At the concentration of 0.5 μL/L 1-MCP treated Xinfengmilu peach fruit had the best postharvest storage performance,making it a suitable choice for maintaining high quality fruit during storage.
