新疆冬小麦选育品种苗期耐盐性鉴定
Evaluation of Salt Tolerance in Winter Wheat Cultivars in Xinjiang at Seedling Stage
摘要
Abstract
[Objective] This project aims to initially determine the slat tolerance of winter wheat through plant changes during wheat seedling stage under salt stress and explore the early screening methods of wheat salt tolerant germplasm,thus screening salt tolerant varieties of winter wheat in Xinjiang in the hope of providing the material basis for the breeding of new salt tolerant wheat varieties.[Method] 46 cultivars of winter wheat suitable to be planted in southern and northern Xinjiang were chosen to be the experimental materials,and the water cuhure method was used to study the difference in salt tolerance of the tested cultivars at seedling stage.[Result]The salt tolerance of the tested winter wheat varieties in Xinjiang varied greatly.There were 3 varieties with strong salt tolerance,namely,Xindong 18,Kadong 3 and Honghe 1.These three species showed high yield at the seedling stage.There were 2 varieties with strong salt tolerance,21 varieties with moderate salt tolerance,the rather weak ones were 17 and three had weak salt tolerance.[Conclusion] The correlation analysis of salt tolerance showed that the inhibitory effect on root growth was stronger than that on stem and leaf growth,so root length and root number can be regarded as a sensitive index for measuring winter wheat salt tolerance.关键词
