高温胁迫对2个冬小麦品种幼苗的影响
Effects of High Temperature Stress on Seedlings of Two Winter Wheat Varieties
摘要
Abstract
[Objective] The study aimed to compare the effects of high temperature stress on the physiological index of the seedlings in 2 winter wheat varieties so as to lay the foundation for the further research of their tolerance mechanism. [ Method] With the winter wheat varieties of Jimai 19 and Linmai 2 as tested materials, using the dish planted method, their seedlings were treated at the high temperature stress at 40 ℃ for 7 d to compare their physiological index such as plant height, dry weight, Fv/Fm, relatively conductivity and pigment content. [Result] Compared with CK variety, the high temperature stress could decrease the contents of anthocyanosides, chlorophyll and carotenoids, reduce the plant height and the Fv/Fm value of Linmai 2, increase its relatively conductivity and had obvious reduction on its dry weight; the high temperature stress could restrain the plant height of Jimai 19, but had no influence on its other index. [ Conclusion ] The ability of the tolerance on the high temperature stress for Jimai 19 was stronger than that for Linmai 2.关键词
