沉水植物对逆境胁迫的响应研究进展

Advances in Response of Submerged Macrophytes to Stress

沉水植物在水生生态系统中发挥着重要作用,尤其是在污染水体中的恢复与重建已成为水环境生态修复研究的重点,重金属、有机物和高营养盐等是影响沉水植物生长的主要环境污染胁迫因子,探索沉水植物在逆境胁迫条件下的适应能力是当前研究需要解决的关键问题之一。综述了沉水植物在重金属、有机物和高营养盐逆境胁迫下生理形态和抗氧化系统变化的研究情况,旨在深入了解沉水植物对逆境胁迫的耐受机制,为生态环境修复中沉水植物的筛选与重建提供理论依据。

Submerged macrophytes play an important role in aquatic ecosystems,especially in the recovery and reconstruction of polluted water bodies,which have become the focus of ecological research on water environment.Heavy metals,organic matter and high nutrients are the main environmental pollution stress factors affecting the growth of submerged macrophytes.Exploring the adaptability of submerged macrophytes under adverse stress conditions is one of the key issues that need to be solved in current research.The research on the physiological morphology and antioxidant system of submerged macrophytes under the stress of heavy metals,organic matter and high nutrients was reviewed.The aim is to understand the tolerance mechanism of submerged macrophytes to stress,and provide a theoretical basis for the screening and reconstruction of submerged macrophytes in ecological restoration.
