目的 研究1-MCP结合臭氧处理对水晶葡萄低温贮藏期间品质的影响，以期为延长水晶葡萄采后保鲜期提供依据。方法 用浓度为1 μL/L的1-MCP先熏蒸2 h，随后使用4个不同浓度的臭氧对其处理2 h，处理完后贮藏于温度为(1±0.3)℃、相对湿度为(90±5)%的保鲜库内。结果 经1-MCP结合浓度为4 mg/L的臭氧处理贮藏到60 d时，腐烂率(20.43%)、褐变率(40.44%)、脱粒率(33.43%)均低于其余各处理组，可溶性固形物(13.36%)、可滴定酸(0.48%)含量均高于其余各组，维生素C(82.71 mg/kg)、多酚(398.62 mg/kg)含量也高于其余各组。结论 使用1-MCP熏蒸后，再使用4 mg/L的臭氧进行处理，更有利于维持水晶葡萄贮藏期间的品质。

The purpose is to study the effect of 1-MCP combined with ozone treatment on the quality of crystal Grape during low-temperature storage and to provide basis for prolonging the storage period of crystal grapes. Crystal grapes were first fumigated with a concentration of 1 μL/L 1-MCP and then treated with 4 different concentrations of ozone. After treatment, Crystal grapes were stored in fresh-preserved storehouse with a temperature of (1±0.3)°C and relative humidity of (90±5)%. The results showed that the rot rate (20.43%), browning rate (40.44%), and the threshing rate (33.43%) of the appearance phase indexes were lower than the remaining treatment groups when the 1-MCP combined with ozone treatment with a concentration of 4 mg/L was stored in 60 d, the content of soluble solids (13.36%) and titratable acids (0.48%) in the taste evaluation indexes were higher than that of the other groups, and the nutrient indexes vitamin C(82.71 mg/kg) and polyphenol (398.62 mg/kg) were also higher than the other groups. From the above, that used of 1-MCP fumigation and used of 4 mg/L ozone for treatment were more conducive to maintaining the quality of crystal grapes in during storage.
