摘要/Abstract

摘要： 【目的】研究1-甲基环丙烯（1-MCP）对水蜜桃新凤蜜露采后低温贮藏品质的影响。【方法】在（1.0±0.5） ℃低温条件下,以水蜜桃新凤蜜露为试验材料,设置0（CK）、0.5、1.0、1.5 μL/L 4个浓度1-MCP处理,分析1-MCP 对新凤蜜露采后贮藏果实硬度、可溶性固形物含量、呼吸速率、可滴定酸含量、好果率、失重率的影响。【结果】在低温贮藏过程中,0.5 μL/L 1-MCP处理下新凤蜜露果实硬度的下降速度一直比较平缓,在采后贮藏20 d和25 d时,仍保持较高水平,且显著高于1.0 μL/L 1-MCP和1.5 μL/L 1-MCP处理（P<0.05）;在贮藏第25天时,0.5 μL/L 1-MCP处理的可滴定酸含量仍最高,为0.59 %,极显著高于CK（P<0.01）,显著高于1.0 μL/L 1-MCP和1.5 μL/L 1-MCP处理（P<0.05）;CK的呼吸速率变化较3个1-MCP处理快,其活跃程度高;CK的呼吸速率在贮藏第10 天达到最高,为81.23 mg/（kg·h）;自贮藏第10天后,0.5 μL/L 1-MCP处理的果实失重率显著低于1.0 μL/L 1-MCP和1.5 μL/L 1-MCP处理（P<0.05）。【结论】浓度为0.5 μL/L 1-MCP处理的水蜜桃新凤蜜露采后贮藏效果表现最佳,可成为贮藏期间保持果实品质上乘的适宜选择。

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.
