| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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. |
