| 摘 要： | 为了解海滨木巴戟(Morinda citrifolia)生长的抗逆性,对西沙群岛东岛的海滨木巴戟的生物学和生理生态特征进行了研究。结果表明,海滨木巴戟属于阳生性植物,具有较强的光资源竞争能力;其叶片氮、磷含量、叶绿素b含量较高,是其长期适应热带海岛生境的重要原因。海滨木巴戟叶片的海绵组织及气孔密度大,导管直径小,丙二醛含量、超氧化物歧化酶活性和过氧化氢酶活性高,脯氨酸含量低,均表明其具有较强的抗旱性。且生长环境中土壤的氮含量低,盐分含量高。因此,海滨木巴戟可作为热带海滨植被恢复中的优良适生物种。

| Abstract: | In order to understand the resistance of Morinda citrifolia, its eco-physiological characteristics were studied grown in Dongdao of Xisha Islands, China. The results showed that M. citrifolia was a heliophyte with strong competitive ability for light resources. The contents of N, P and chlorophyll b were high in leaves, which was an important character in adaptation to tropical costal island habitat. M. citrifolia had big sponge tissue and stoma density with small vessel diameter. The content of malondialdehyde, activities of superoxide dismutase and catalase were high with low proline content, which indicated that M. citrifolia had strong drought resistance. In addition, N content in soil was low with high salt content. So, M. citrifolia could be used as one of the tool species in the vegetation restoration in tropical coast. |
