| 摘 要： | 为了解热带珊瑚岛对植物生长的影响,对狗牙根(Cynodon dactylon)、大叶相思(Acacia auriculaeformis)和木麻黄(Casuarina equisetifolia)在热带珊瑚岛的生态适应性进行了研究。结果表明,与海南文昌苗木基地的同种植物相比,珊瑚岛胁迫生境下3种植物叶片中的抗氧化酶活性(SOD、CAT和POD)和脯氨酸含量均显著提高(P0.05);大叶相思和狗牙根的丙二醛含量也极显著提高(P0.01),但木麻黄则没有显著变化。这表明这些植物可以通过提高抗氧化酶活性和渗透调节物质含量来适应珊瑚岛的胁迫生境。

| Abstract: | In order to understand the effect of the environment of tropical coral islands on plant growth, the ecological adaptability of three species grown in tropical coral islands was studied, including Cynodon dactylon, Acacia auriculaeformis and Casuarina equisetifolia. The results showed that the antioxidant enzyme activities, such as SOD, CAT and POD, and proline content in three species grown in coral islands increased significantly (P < 0.05) compared with the same species grown in Seedling Base in Wenchang, Hainan Province. The malondialdehyde content in leaves of A. auriculaeformis and C. dactylon grown in coral islands also significantly increased (P < 0.01), while it had no difference in C. equisetifolia. Therefore, it was indicated that these species would adapt well to the harsh environmental conditions on the coral island through enhanced activities of antioxidant enzymes and increased contents of osmotic adjustment substances. |
