摘要： The effects of different buckle shed time on catalase (CAT) activity and malondialdehyde (MDA) content in grape leaves (tender, function and old leaves) were studied involving the following: without buckle shed (CK), buckle shed on January 1st, 2018 (BS I), buckle shed on January 20th, 2018 (BS II), sampled 6 times with interval one week. The result showed that buckle shed increased the CAT activity of grape tender and function leaves, the grape tender leaves of BS. and BS. at the sampling date 4 had the highest and increased by 32.36% and 39.14% respectively, but the grape function leaves of BS. and BS. at the sampling date 2 had the highest and increased by 25.46% and 26.53% respectively. The buckle shed had no significant effect on CAT activity of grape old leaves in early sampled date. The different buckle shed time had no significant effect on CAT activity of grape leaves. Buckle shed increased the MDA content in grape tender leaves, the grape tender leaves of BS. and BS. at the sampling date 4 had the highest and increased by 204.0% and 202.7% respectively. Buckle shed decreased the MDA content in grape function leaves, the grape function leaves of BS. and BS. at the sampling date 2 had the lowest and increased by 46.39% and 48.19% respectively. The MDA content of grape old leaves in the early sampled was decreased compared with control, but in the later sampled increased.
