Abstract:

To establish an effective, reliable identification method and evaluation index of soybean resistance to low temperature and weak light, twelve vegetable soybean strains were primary studied on the difference of adaptability to low temperature and weak light with germination time, survival ratio, index of biochemistry and morphology. The result was proved germination time, survival ratio, active of SOD, POD and CAT of vegetable soybean existed evident differences under the condition of light (60-80μmol/(m2?s)), temperature(12℃), and relevant analysis showed that the protective enzyme activity and light temperature combination was very significant positive correlation.
