| 摘 要： | 以Ⅱ优7号、冕粳147、合系22-2和合系22为材料,设4个不同浓度的NaCl模拟盐胁迫,研究水稻发芽和幼苗生长的一些形态指标。结果表明：不同水稻品种对盐胁迫敏感性存在差异;发芽期间根和芽对盐胁迫敏感性不同,150mmol/L高浓度时对芽的抑制作用均大于根;不同的盐浓度对幼苗的生长有一定的抑制作用,地上部比地下部对盐害更敏感。

| Abstract: | The experiments have four different concentrations of salt stress,the guide line of morphologic in the germination period and seed period were studied with four rice of Ⅱyou 7,Mianjing 147,Hexi 22-2 and Hexi 22.The results indicated that varieties of rice were significant of difference sensitive to salt stress.Germen was more restrained than root with 150mmol/L NaCl concentration.The growth of seeding was restrained with different concentrations of salt stress,and aboveground was less tolerance than underground portion. |
