Study on cold hardiness and its physiological and biochemical characteristics of winter turnip rape (Brassica campetris)

摘要：

Superoxide dismutase(SOD)activity, peroxidase(POD) activity, soluble sugar contents, and soluble protein contents of 8 winter turnip rape cultivars were tested during overwintering period. The results indicated: the change in enzyme activity and the contents of soluble substace were similar of 8 cultivars, but the degree of change was difference in cultivars. The studies showed that the enzyme actiwity and soluble substance contents of strong hardiness cultivars higher than weak one. POD activity, soluble protein contents and soluble sugar contents were close related with winter hardiness of winter turnip rape, which could be regarded as one of the guides for selecting the hardiness cultivars in different low temperature.
