硅肥对于提高植物抗性的作用机理研究进展

Research Progress on the Mechanism of Silicon(Si)in Increasing Plant Resistance

硅元素虽然不是植物的必需营养元素,但越来越多的研究结果表明,硅对于植物抵抗生物与非生物的胁迫具有重要作用。近年来,关于硅元素对植物的功能研究非常活跃。从硅元素能显著提高植物抵抗生物、非生物胁迫能力,硅肥根施和叶施的争论,硅在植物体内的运输及相关基因,硅介导植物产生系统抗性的分子机制等方面对硅元素在植物与病原物互作中的作用机理进行了综述,并提出了今后研究方向,为更合理利用硅肥提供一定的理论基础。

Although silicon is not an essential nutrient for plants,more and more research results show that silicon plays an important role in plants’resistance to biological and abiotic stresses.In recent years,research on the function of silicon on plants has been very active.This paper reviewed the mechanism of silicon in plant pathogen interaction from the aspects of silicon can significantly improve plant resistance to biotic and abiotic stresses,the debate on silicon application in roots and leaves,silicon transport in plants and related genes,and silicon mediated molecular mechanism of plant systemic resistance.The research direction in the future was put forward to provide a theoretical basis for more rational use of silicon fertilizer.
