摘　　要：以"8-102"品种甜樱桃为研究材料,对高浓度CO2处理不同时间(48、96、144h)后的甜樱桃果实的呼吸强度、果实颜色以及相关酶活性进行了研究。结果表明,不同时间的高浓度CO2处理均不同程度地抑制了果实的PPO活性,尤其短时高浓度CO2处理明显地延缓了果皮的着色过程,抑制了果实的呼吸强度和PPO、POD酶活性以及降低了MDA含量,减轻了果实的褐变程度,贮藏后期果实保持较好的贮藏品质。The respiration rate and color and related enzyme activities of sweet cherry fruit by treated with high concentration of CO2 for different times（48,96,144h）were studied.The results showed that the polyphenol oxidase （PPO） activities of fruit by treated with high concentration of CO2 for different times were inhibited different degrees,especially the activities of PPO, POD and respiration rate were inhibited significantty and the content of malondialdehyde（MDA） reduced for short-term treatment with high concentration of CO2, the coloring process of pericarp was delayed,and it alleviated the brownina of fruit and maintain a better storaoe quality post-storage.
