摘　　要：病原微生物侵染引起的果蔬病害日趋严重,现阶段果蔬病害的防治措施主要依赖化学防治,但长期大量施用合成农药的弊端如化学残留、环境污染、抗药性病原菌株出现等日益凸显。近年来,生物防治由于其安全性及高效、经济、环保等优点,成为研究热点。荧光假单胞菌(Pseudomonas fluorescens)分布广泛,施用方便,许多菌株能有效抑制多种病原微生物,成为最具应用价值的一类生防菌和根际促生菌。本文综述了荧光假单胞菌控制果蔬病害的生防效果、主要作用机制(直接寄生作用、营养物质和空间位点竞争、次生抗性代谢物、诱导宿主系统抗性)以及菌剂混配、物理方法、化学处理、分子技术在提高荧光假单胞菌生防效力等方面的研究进展,为荧光假单胞菌在生物防治领域的进一步开发利用提供一定的基础资料。Fruit and vegetables diseases are always caused by pathogenic microorganisms and traditionally,chemical control such as fungicide treatment was widely applied,which helped to cause chemical residues,environmental pollution and resistance in fungi,etc.rlternatively,microbial biocontrol methods were favored due to their safety,effectiveness and environmental harmlessness.In this paper,we reviewed the update investigations about the biocontrol effect and involved mechanisms of Pseudomonas fluorescens,one kind of biocontrol bacteria and plant growth-promoting rhizobacteria.We provided the basic information of P.fluorescens on biological control and discussed related mechanisms including parasitism,competition for nutrients and space sites,production of secondary resistance metabolites and initiation of systemic resistance,responsible for the biocontrol effect.rlso,we illustrated the current research result for the improvement of biocontrol efficacy,such as inoculant mixing,physical methods,chemical treatments and molecular technologies.
