| 摘 要： | 研究了互花米草在不同没顶水淹时间处理下,株高、叶面积等生长指标以及叶片光合速率与色素、脯氨酸、可溶性糖和蛋白质含量等生理指标变化情况。结果表明,随着水淹时间延长,米草株高和叶面积呈下降趋势,叶片光合速率下降;叶片中自由水/束缚水、叶绿素和类胡萝卜素含量、可溶性糖在不同水淹时长处理之间也存在显著差异;但可溶性蛋白质和游离脯氨酸含量在各处理间差异无显著性。

| Abstract: | In this paper,the variations of plant height,leaf area,leaf photosynthetic rate,photosynthetic pigment,praline,soluble sugar and protein content for Spartina alterniflora seedlings related to various waterlogging time length were investigated.The results showed that the height and leaf area tended to decrease with the increaseing waterlogging duration.Leaf photosynthetic rate decreased significantly with increaseing waterlogging.There were significant differences between various waterlogging time and the ratio of free water to bound water,photosynthetic pigment,and soluble sugar content.Content of protein and proline tended to remain stable. |
