摘　　要：从地上部叶片光合作用、地下部根系养分吸收和整体氧化胁迫3个方面综述了镉对不同植物生长的抑制作用。近年来,越来越多的研究者发现硒对镉毒害具有缓解作用。因此,综述了不同植物中硒如何调控改善镉胁迫下植物的光合作用、养分吸收和抗氧化能力。同时分析了硒如何降低植物中镉含量,并对未来的研究进行展望,以期为寻找有效缓解镉毒害的生产技术提供理论参考。The inhibitory effects of cadmium on the growth of different plants were reviewed from three aspects,including photosynthesis of aboveground leaves,nutrient absorption of underground roots and overall oxidative stress.In recent years,more and more researchers have found that selenium has a mitigating effect on cadmium toxicity.Therefore,this paper then summarizes how selenium in different plants regulates and improves photosynthesis,nutrient absorption and antioxidant capacity of plants under cadmium stress in response to the above three aspects of cadmium toxicity.At the same time,how to reduce the cadmium content in plants by selenium was analyzed,and the future research was prospected,in order to provide a theoretical reference for seeking the production technology of effective alleviation cadmium toxicity.
