| 摘 要： | 以五山丰占、华航油占、原两优、谷优四4个水稻品种幼苗为材料,采用150 mmol/L NaCl对其进行盐胁迫处理,并测定了处理后水稻幼苗的根长、株高、叶绿素和丙二醛(MDA)含量,以研究NaCl胁迫对不同水稻品种生长和生理特性的影响。试验结果表明:不同水稻品种经NaCl处理后,其株高和根系生长均受到不同程度的抑制,水稻幼苗鲜质量和体内所含的自由水下降,叶片叶绿素含量降低,MDA含量增加。

| Abstract: | The effect of NaCl stress on the growth and physiological characteristics of different rice varieties were studied by using the seedlings of four rice varieties(Wu-shan-feng-zhan,Hua-hang-you-zhan,Yuan-er-you,Gu-you) as materials and determining the root length,fresh height,chlorophyll and malondialdehyde(MDA) content of the different rice seedlings after treatment with 150 mmol/L NaCl.The results showed that the plant height and root growth of different rice varieties was inhibited to a certain extent.The fresh weight and free water contained in the body were decreased.The chlorophyll content was lowered and MDA content were increased after treated with 150 mmol/L NaCl. |
