中文摘要：
土壤中的重金属污染尤其是镉（Cd）污染是目前全球关注的环境热点问题之一。Cd对于人体和动植物都是非必需元素，且有很强的毒性。Cd对植物的毒害机理研究相对人体和动物起步较晚，最近也逐渐成了重金属研究的焦点。越来越多的研究证实Cd对植物的毒害首先是作用于细胞内的氧化还原系统，造成活性氧（ROS）积累一氧化胁迫，进而引起一系列氧化还原反应，使抗氧化系统发生改变。本文回顾和总结了进人植物体内的Cd与植物的抗氧化系统关系的研究进展，详细阐述了其氧化胁迫的可能机理，并提出了新的研究方向。
英文摘要：
Soil contamination by heavy metals, especially by cadmium （Cd）, has been one of the world wide environmental hot issues in recent years. Cd is non-essential element for humans and animals as well as plants, and is highly toxic to them. The study of mechanisms of Cd toxicity to plants is relatively later, but recently has been becoming a studying focus. There are ample evidence that toxicity of Cd to plants is due to Cd inducing oxidative Stress in plant cells and consequently ROS especially hydrogen peroxide （H2O2 ） accumulation, which will result in a series of reaction in redox system and changes of antioxidant system. This paper reviews the advances of study on Cd-induced oxidative stress and possible mechanisms, and proposed a new research field.
