目的 为探究1-MCP结合低温处理对“阳光玫瑰”葡萄贮藏品质的变化。方法 以葡萄为试材，分别用0.5、1、1.5、2 μL/L 1-MCP进行处理，无1-MCP处理的作为对照(CK)。将试材置于温度为(0±0.5)℃、相对湿度为75%的保鲜库中贮藏，每20 d测定1次葡萄的生理指标。结果 较其他浓度处理，1 μL/L 1-MCP结合低温处理，抑制了“阳光玫瑰”葡萄的硬度、呼吸强度、MDA含量和PPO活性的升高，减少了落粒率和腐烂率的发生，延缓了SSC、TA含量的下降。结论 1 μL/L1-MCP结合低温处理，推迟了“阳光玫瑰”葡萄在贮藏期间的后熟衰老进程，最大限度地保持了果实的新鲜品质，延长了果实的贮藏期，可作为“阳光玫瑰”葡萄规模化贮运保鲜的实用技术。

The work aims to investigate the changes in storage quality of "Shine Muscat" grapes treated with 1-MCP combined with low-temperature treatment. Grapes were used as test materials, and treated separately with 0.5, 1, 1.5, 2 μL/L 1-MCP. Those without 1-MCP treatment were used as controls (CK). The test materials were stored in a fresh-keeping warehouse at (0±0.5)℃ and 75% relative humidity, and the physiological indicators of grapes were measured every 20 days. As a result, compared with other concentration treatments, the combination of 1 μL/L 1-MCP and low-temperature treatment suppressed the increase in hardness, respiratory intensity, MDA content, and PPO activity of "Shine Muscat" grapes, reduced the occurrence of grain drop and decay rates, and delayed the decrease in SSC and TA content. In conclusion, the combination of 1 μL/L1-MCP and low-temperature treatment delays the post ripening and aging process of "Shine Muscat" grapes during storage, maximally maintaining the fresh quality of the fruits and prolonging their storage period. It can be used as a practical technology for large-scale storage, transportation, and preservation of "Shine Muscat" grapes.
