摘　　要：锰是植物体内重要生命元素之一,在植物的生长发育过程中发挥着重要作用。它对植物的光合放氧、维持细胞器的正常结构、活化酶活性等方面具有不可替代的作用。但是,过量的锰亦会对植物造成毒害。它可抑制Fe2+和Mg2+等元素的吸收及活性,并可破坏叶绿体结构导致叶绿素合成下降及光合速率降低。作者详细阐述了锰在植物体内的生理功能及植物的多种解毒或耐性机制。并对锰与植物关系方面的研究做出了进一步展望。Manganese is one of the most important biotic elements in plants which plays a significant part of role during the plants growth and development.It has an irreplaceable role in plants photosynthetic oxygen evolution,maintaining the normal structure of cell organelles and enzyme activity.However,excess manganese will lead to manganese toxicity and it can inhibit the absorption and activity of Fe2＋ and Mg2＋ and other elements,which lead to destruction of chloroplast structure and decrease of chlorophyⅡ synthesis and photosynthetic rate.Author illustrates physiological function of manganese in plants and also various mechanisms of plants to overcome manganese toxicity.Meanwhile,more prospects on the research between manganese and plants have been introduced.
