抗寒性不同的葡萄品种叶片中氧化酶活性及变化规律

Activity of Oxidase in the Leaves of Grape Varieties with Different Cold-resistance and Regularity of the Activity Change

生长后期研究不同抗寒性的葡萄品种叶片中氧化酶（ＣＡＴ、ＰＯＤ、ＳＯＤ、ＡＳＡＰＯＤ）活性及变化规律表明：抗寒性强的品种酶活性高，抗寒性差的品种酶活性低，且随着气温的下降而下降，以抗寒性强的品种变化得慢，抗寒性差的品种变化得快。

This study indicated: in tile late growing season, the activity or oxidase (CAT, POD, SOD ASAPOD) in tile leaves or grape varieties with different cold-resistance and the activity change regularity were different. The variety with strong cold-resistance have high activity of oxidase and change slowly, while the variety with poor cold-resistance has low activity or oxidase and change quickly.
