摘要: 土壤盐分过高抑制植物生长,已成为盐碱地区域农业发展的主要限制因素。植物根际促生细菌(Plant growth-promoting rhizobacteria,PGPR)促进盐碱地作物生长,增强作物耐盐能力,进而诱导作物盐耐受性。对能诱导植物盐耐受性的PGPR种类作了总结,并从PGPR自身产生物质及植物受到PGPR作用后生理变化两个方面评述PGPR提高植物耐盐性的机制。了解PGPR提高植物耐盐性的机理,为大规模利用微生物提高作物在盐碱等条件下的稳产高产提供理论依据。

Abstract: Soil salinity inhibits the growth of plants and has become one of the major factors that limit agricultural productivity. Plant-growth-promoting rhizobacteria (PGPR) colonizing the rhizosphere of many plants stimulated plant growth under salt stress condition, meanwhile, PGPR can induce plant salt tolerance. This paper reviewed PGPR species that could confer plants induced salt tolerance and the potential mechanisms of PGPR improving plant salt tolerance was reviewed from two aspects including PGPR metabolite and physiological changes in plants driven by PGPR under salt stress condition. Understanding the mechanisms responsible for induced salt tolerance conferred by PGPR, will provide theoretical basis for the large-scale application of rhizobacteria in saline environments.

Key words: plant-growth-promoting rhizobacteria (PGPR), plant, salt stress, induced salt tolerance
