选用11个冬小麦品种，以NaCl溶液为盐胁迫，探究冬小麦品种在不同浓度的NaCl溶液胁迫下8个性状指标上的差异，并对这些指标的相对值采用差异显著性分析。结果表明，随着NaCl盐溶液浓度升高，小麦萌发期各指标的相对耐盐系数均下降，且发芽率、发芽势、根长、胚芽鞘长、苗高、第1片叶的生长速率以及苗鲜质量在不同品种及不同浓度处理间差异显著；但NaCl盐溶液对小麦根数的影响差异不显著；因此，以上7个生理性状指标可以作为冬小麦萌发期室内筛选的有效指标；11个供试品种中，德抗961、青麦6号在萌发期表现出较强的耐盐能力。

In this study ,11 winter wheat species were selected to explore the differences of eight trait indicators under different concentrations of NaCl solution ,which was chosen as the salt stress .And the relative values of the indicators were analyzed by the analysis of the outstanding difference .The results showed that as the concentration of NaCl salt solution increases the relative salt tolerance coefficient of each index of the winter wheat decreased during the germination .In addition ,there were significant differences among the germination rate ,germination potential ,root length ,coleoptile length ,seedling height ,and the growth rate of the first leaf as well as the fresh weight of seedlings between different species and different concentrations .But the effect of NaCl salt solution on the number of the wheat roots was not significant .So the seven indexes of physiological traits can be used as an effective indicator of the selection of winter wheat during the germination indoor .The study also indicated that the tested varieties of Dek-ang 961 and Qingmai 6 exhibit stronger salt tolerance during the germination stage .
