塔里木河流域4种野生豆科植物种子耐盐性研究

应用室内培养皿萌发试验，在0、0.4%、0.8%、1.2%和1.6% 5个质量分数的盐溶液胁迫下，对采集于塔里木河流域的野生胀果甘草Glycyrrhiza inflata、疏叶骆驼刺Alhagi sparsifolia、苦豆子Sophora alopecuroides、苦马豆Sphaerophysa salsula 4种牧草种子萌发时的耐盐碱性进行了检测。结果表明：4种牧草种子对盐胁迫的耐受性不同，骆驼刺和甘草具有较强的耐盐性，苦马豆次之，苦豆子的耐受性最差；低盐胁迫对4种种子的萌发、胚芽、胚根的生长都有一定促进作用；随着盐质量分数增高，发芽率呈下降趋势，胚芽、胚根的生长也受到抑制。

Study on the salt tolerance of four wild legumes in Tarim River Basin

The salt tolerance of 4 wild legumes,including Glycyrrhiza inflata,Alhagi sparsifolia,Sophora alopecuroides and Sphaerophysa salsula from Tarim River basin,were evaluated under 5 levels of salt stress(0,0.4%,0.8%,1.2% and 1.6% of NaCl solution) in seed germination period.The result showed that their salt tolerance was different,in which,G.inflata and A.sparsifolia performed the better salt endurance,and followed by S.salsula and S.alopecuroides.The low concentrate salt solution stimulated the seed germinati...
