非生物胁迫下硅素营养对植物的作用及其机理

Effect of Silicon on Plant and Relevant Mechanism under Abiotic Stresses

硅是对植物生长有益的一种营养元素,能提高作物的产量,改善作物品质。目前有文献报道,硅还可以提高植物对非生物胁迫的抵抗能力。综述了国内外有关硅素营养在减轻铝、锰、盐分、重金属对植物毒害中的作用及机理方面的研究。

Silicon was one of beneficial mineral elements for the growth of plants. It could increase the yields of crop and improve the qualities of crop. Some literatures reported silicon could improve plants the resistant ability of abiotic stresses. The paper reviewed the effect of silicon on alleviation of toxicity of Al^(3+),Mn^(2+) ,salinity and heavy metal to plants and their mechanisms.
