| 摘 要： | 为鉴定苜蓿品种耐盐性的差别,以18个苜蓿品种种子为试验材料,在6个NaCl浓度下对各品种种子萌发期的耐盐性进行了研究,其品种间存在显著性差异(P<0.05,P<0.01)。通过对不同品种种子的发芽势、发芽率、耐盐适宜浓度和半致死浓度4个鉴定指标进行综合分析,结果表明:WL232hq和三得利的耐盐性最强,其次是WL232和游客,耐盐性最弱的金达和龙引BeZa87。

| Abstract: | For identifying the differences of salt resistance of alfalfa varieties,the seeds of 18 alfalfa were taken as materials to analyze the salt resistance of 18 alfalfa on seed germination under 6NaCl concentrations and there were significant differences between the 18 alfalfa(P<0.05,P<0.01)varieties.Through analyzing the four indexes of the seed germination potential,germination rate,the concentration of salt tolerance and the concentration of half lethal,the result showed that the salt tolerance of WL232hq and Sandeli were the strongest,followed by WL232 and Youke,Jinda and Longyin BeZa87 were the weakest. |
