摘要/Abstract

摘要： 土壤盐渍化日趋严重,盐害已成为植物生产中严重的生境胁迫。因此,土壤盐渍化问题的研究成为近年来的热点。盐胁迫主要造成植物对土壤水分和养分吸收障碍。研究发现,植物内生真菌能在盐胁迫下促进植物对土壤养分和水分的吸收,缓解盐胁迫带来的伤害,从而提高植物生物量,维持植物生长和群体结构。本文从提高植物抵御盐胁迫的内生真菌的发掘、内生真菌对植物抵御盐胁迫的影响以及内生真菌的研究前景和目前存在的相关问题进行探讨和综述,期望能为发现和利用协助植物抵御盐害的微生物资源提供参考和依据。

Abstract: Soil salinization is becoming increasingly serious,and it has become a major constraint in plant production. Therefore,research on soil salinization has become a hotspot in recent years. Salt stress mainly causes difficulties in plant uptake of soil water and nutrients. Endophytic fungi may promote plant uptake of soil water and nutrients under salt stress,alleviate salt-induced damages,thereby maintaining plant growth,population structure and biomass. In this paper,we summarized the discovered endophytic fungi and their effects on plant resistance to salt stress,discussed the research prospects of endophytic fungi and current issues,aiming to provide reference and basis for discovering and utilizing of microbial resources to enhance plants resistance to salt stress.

Key words: salinization, plant, endophytic fungi
