目的 研究在冷藏条件下臭氧熏蒸方法对木纳格葡萄采后贮藏的适用性。方法 以新疆木纳格葡萄为试材，研究在0 ℃和−1 ℃条件下的对照组，以及经2.5 μL/L和5 μL/L臭氧熏蒸处理后对木纳格葡萄贮藏效果和品质的影响。结果 在−1 ℃下经2.5 μL/L臭氧熏蒸处理的木纳格葡萄，其贮藏期间呼吸强度弱，很好地保持了果实的可溶性固形物含量和可滴定酸含量，贮藏各时期果实腐烂率、落粒率较低，贮藏后具有较高的好果率，保持了果实的品质。结论 在−1 ℃下经2.5 μL/L臭氧熏蒸处理为木纳格葡萄最适宜的环境贮藏参数。

The work aims to study the applicability of ozone fumigation methods in the Munage grape postharvest storage under refrigerated conditions. With Xinjiang Munage grape as the tested material, the control group respectively at 0 ℃ and −1 ℃, and the influence of 2.5 μL/L and 5 μL/L ozone fumigation on the storage effect and quality of Munage grape were studied. The results showed that the respiration intensity of Munage grape treated by 2.5 μL/L ozone fumigation at −1 ℃ was weak, and the fruit soluble solid content and titratable acid content were kept well during the storage. The decay rate of the fruit and the shattering rate were low. The rate of intact fruit after the storage was higher, which helped maintain the fruit quality. 2.5 μL/L ozone fumigation at −1 ℃ is the most suitable environmental storage parameter for Munage grape.
