| 中文摘要 | The allelopathic effects of two submerged macrophytes, Najas minor and Potamogeton malaianus, on growth, photosynthesis and antioxidant systems of Scenedesmus obliquus were assessed in coexistence experiments. The growth of S. obliquus was significantly suppressed by the two macrophytes. Moreover, P. malaianus showed the stronger growth inhibition effect on S. obliquus than N. minor. P. malaianus obviously inhibited the photosynthetic rate of S. obliquus, while N. minor had no inhibitory effect. Lipid peroxidation and three antioxidant enzymes activities (superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD)) of S. obliquus were investigated at the end of the co-cultures. The two macrophytes significantly enhanced the malondialdehyde (MDA) content, a product of lipid peroxidation, in S. obliquus. Activities of the three antioxidant enzymes of S. obliquus were simultaneously stimulated in P. malaianus treatment, while no significant variation of POD activity was observed in N. minor treatment. The results indicated that the two macrophytes N. minor and P. malaianus had significant allelopathic effects on S. obliquus. However, the two macrophytes influenced S. obliquus in different ways. |
