摘要
本试验通过人工低温处理 ,探讨了萌发进程中三个熟期类型大豆品种间耐冷性生理指标间的差异 ,结果表明 :低温萌发进程中两早熟品种较中晚熟品种的 CAT酶活受抑程度小 ,可溶性蛋白含量增幅大 ,但 MDA含量变化趋势一致。
The physiological index difference of cold tolerance among three maturity type of soybean was studied during the course of germination by Controled low temperature stress. The results showed that two early variety's CAT enzyme activity inhibition was smaller, increment of soluble protein content was larger than those of the late-middle variety. But variation of MDA content did not coincide with variation tendency of variety maturity. The early maturity variety's adaptation to low temperature stress was stronger than that of late-middle maturity varieties.
