摘要
盐胁迫是影响果树生长发育的重要因素之一,影响了果树的一系列生理生化特性,高浓度的盐会造成果树减产甚至死亡。根据国内外相关的文献资料,现从外部形态、光合特性、离子含量和膜透性4个方面对盐胁迫下果树的响应机制进行了探讨,并从提高酶的抗氧化能力、合成渗透调节物质以及离子的选择性吸收3个方面对盐胁迫下果树的缓解机制进行了综述。
Salt stress was one of the important factors affecting the growth and development of fruit trees,a series of physiological and biochemical characteristics would be affected under salt stress.The high concentration of salt will cause the fruit trees yield reduction and even death.According to the domestic and foreign literatures,this article from the response mechanism of fruit trees under salt stress in 4aspects of the external morphology,photosynthesis,ion content,membrane permeability were discused and the alleviation mechanism of fruit trees under salt stress in 3aspects of improving the enzymatic antioxidant capacity,synthesis of osmotic regulation substances,lon selective absorption were reviewed.
