摘要
文章对盐胁迫下大麦幼苗生理指标进行了分析研究。结果表明,随NaCl浓度的升高,大麦茎叶中可溶性糖、脯氨酸含量增高,K+/Na+降低;大麦茎叶中脯氨酸含量随NaCl浓度升高呈倍数升高,在0.6%NaCl胁迫下,‘CM72’脯氨酸含量最高达1.526μmol.g-1。在同一NaCl浓度下,不同大麦品种间可溶性糖、脯氨酸含量及K+/Na+差异明显,‘CM72’渗透物质合成能力最强,耐盐性较好,‘泰兴9425’和‘苏啤3号’次之。
Effect of salinity stress on the physiological indexes of barley seedlings was studied.The results showed that the content of soluble sugar and proline in barley shoot increased,and the rate of K＋/Na＋decreased with increasing of NaCl concentration.The proline content of CM72 was 1.526 μmol·g-1 under 0.6% NaCl stress.There were some differences in soluble sugar content,proline content and the rate of K＋/Na＋among different barley cultivars under the same concentration of NaCl.With the high synthetic capability to osmotic compounds,CM72 showed great tolerance to salinity stress,Taixing 9425 and Supi 3 followed with it.
