- 摘要:
- 采用Hogland营养液水培方法，研究了不同浓度NaCl胁迫处理下油菜幼苗过氧化氢酶（CAT）活性、叶绿素含量、丙二醛含量、可溶性蛋白和脯氨酸含量的变化规律。结果表明：随着NaCl处理浓度的增加，油菜幼苗叶片中的CAT活性及叶绿素含量都呈现先上升后下降的趋势，脯氨酸及丙二醛含量升高，可溶性蛋白含量下降。
- Abstract:
- Hoagland solution culture method was applied to investigate the dynamic of several physical and biochemical indexes in the leaves of rape seedings，under different NaCl-stress pressure.The results showed that with the increase of salt concentration，the CAT activity and the chlorophyll content increased firstly，then slowly decreased.The proline content and MDA content increased gradually，and the soluble protein content decreased.The results were good to the integrated management of soil，the improving the salt tolerance of plants and the development and utilization of salt water resources.
