【摘要】：[目的]比较不同基因型扁豆的耐盐性能。[方法]选用品种春扁豆(Ⅰ)(荚为绿色)、绿领红扁豆(荚为紫色)以及超级扁豆(Ⅰ)(荚为绿白色)为试验材料,在种子萌发期间用不同浓度的NaCl溶液进行盐胁迫,采用加权累积隶属函数法综合评定它们的耐盐性能。[结果]3种不同基因型扁豆开始感受盐胁迫的浓度为0.5%NaCl,随着NaCl溶液浓度增加,其种子萌发和幼苗生长受抑制程度加大,但在同一浓度NaCl溶液处理下,受抑制程度不同。[结论]3种基因型扁豆耐盐性能依次为:春扁豆(Ⅰ)绿领红扁豆超级扁豆(Ⅰ)。
[Abstract]:[objective] to compare the salt tolerance of different genotypes of lentils. [methods] A variety of spring lentils (I. E. green lentils, green lentils with purple pods) and super lentils (green and white pods) were selected as experimental materials. During seed germination, salt stress was carried out with different concentrations of NaCl solution. The salt tolerance of three different genotypes of lentils was evaluated by weighted cumulative membership function. [results] the concentration of salt stress of three different genotypes of lentils was 0.5NaCl. with the increase of concentration of NaCl solution, the inhibition of seed germination and seedling growth was increased. But under the same concentration of NaCl solution, the inhibition degree was different. [conclusion] the salt tolerance of three genotypes of lentils was: spring lentils (鈪，
