摘要
植物根际促生菌(plant growth-promoting rhizobacteria,PGPR)是一类能够高密度定殖在植物根际的微生物,兼有抑制植物病原菌、根际有害微生物,以及促进植物生长并增加作物产量的作用,通过对植物根际促生菌的定义、种类、作用机制、研究手段以及应用的分析,表明了PGPR的应用研究对资源的综合利用和环境保护具有重要的理论和现实意义。
PGPR （plant growth -promoting rhizobacteria） are microorganisms which can colonize in rhizosphere at high population density, inhibit plant pathogens and deleterious microorganisms, and promote crop growth and its yield. The analysis of the definition, sort, function mechanism, research methods and the application of PGPR shows that applied studies of PGPR makes great sense in theory and practice for resource utilization and environmental protection.
