盐胁迫条件下甜高粱品种KF0680-1和KF0680-2的萌发及其α -淀粉酶表达研究
Germination and Expression of α-Amylase of KF0680-1 and KF0680-2 ( Cultivars of Sweet Sorghum) under Salt Stress
摘要
Abstract
[Object] The aim was to study on germination and expression of a-amylase of KP0680-1 and KF0680-2 (cultivars of sweet sorghum) under salt stress. [ Method] In the research, KF0680-1 and KF0680-2, cultivars of sweet sorghum, were used to measure related indices of germination and expression of a-amylase to discuss effect of salt stress on two cultivars. [ Result ] Germination of sweet sorghum would be promoted if treated with salt in low concentration and inhibited if treated in high concentration. In the latter condition, roots and seedlings were smaller than that of control group in length, but expression of a-amylase in the two cultivars was promoted under proper salt stress. [ Conclusion ] The research indicates that KFD680-1 and KP0680-2 are inhibited in growth by salt stress and the latter is stronger in salt resistance than the former under salt in low concentration. In addition, expression of a-amylase could be promoted by salt in proper volume. The results provide references for selection of sweet sorghum which could be planted in northwestern areas.关键词
