Effects of waterlogging on growth and physiology of Spartina alterniflora

Abstract

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.
