遗传多样性对在恶劣环境中恢复一种濒危盐碱地植物至关重要

虽然遗传多样性被认为能提高退化植物种群的恢复成功率，但之前研究其对恢复结果的影响的结果却不尽相同。我们假设，遗传多样性对恢复目标植物表现的重要性会随着环境压力的增加而增加，并随着与不同植物连续生命阶段相关的特定植物性状的变化而变化。为了验证这一假设，我们进行了一项全因子普通花园实验，在低氮和高氮条件下，交叉研究盐度和遗传多样性对长江口濒危特有盐碱地植物芒柄蕨的生长和繁殖的影响。遗传多样性对不同胁迫梯度和指标的影响各不相同。在高胁迫（高盐度、低养分）条件下，更高的多样性会增强克隆生长和种子生产等生殖性状，但在低胁迫条件下则不会。植物生长性状在任何胁迫下都没有表现出多样性效应。综述：我们的研究结果强调了在生态恢复中考虑种内遗传多样性的重要性，并有助于解释多样性的环境依赖效应。

期刊介绍： Journal of Ecology publishes original research papers on all aspects of the ecology of plants (including algae), in both aquatic and terrestrial ecosystems. We do not publish papers concerned solely with cultivated plants and agricultural ecosystems. Studies of plant communities, populations or individual species are accepted, as well as studies of the interactions between plants and animals, fungi or bacteria, providing they focus on the ecology of the plants. We aim to bring important work using any ecological approach (including molecular techniques) to a wide international audience and therefore only publish papers with strong and ecological messages that advance our understanding of ecological principles.
