| 摘 要： | 显微化学观察表明，越冬期间，葡萄枝条组织中的全蛋白含量及其变化动态与抗寒性密切相关。主要表现为全蛋白存在于韧皮薄壁细胞中；在抗寒锻炼过程中蛋白质逐渐增加，严冬时达到最大值；且抗寒种类全蛋白含量高，降解迟。随着秋冬光温的降低，过氧化物酶活性逐渐提高，抗寒种类提高幅度大；韧皮部酶活性高于木质部且稳定性强。过氧化物酶活性的适应性变化，对葡萄抗寒力的发展具有重要作用。

| Abstract: | The total protein content and peroxidase activity of grape shoots wasclosely correlated with its cold resistance during the overwintering period.Theobservation shwed,during the cold hardening and overwintering period,the totalprotein of grape shoots gradually increased and the content was the highest in the severewinter;meanwhile,hardy species had more total protein and disintegrated late,Thepeeroxidase activity of grape shoots gradually increased as the temperature fell fromautumn to winter,and the peroxidase activity of hard varieties was stronger;moreever,the peroxidnse activity of pholem was higher than xylem and more stable. |
