中文摘要：

随着植物病害的日趋严重，生物防治已经成为国内外学者研究的重点，其中，荧光假单胞菌尤为重要。本研究综述了荧光假单胞菌的培养特征（形态特征、生理生化特性、培养条件和与其他菌的异同）；从不同类群的植物分离到防治病害的荧光假单胞菌；荧光假单胞菌的生防效果（单独使用和与其他菌或物质交互使用的防治效果）；荧光假单胞菌及活性物质防治植物病害的作用方式和作用机理；荧光假单胞菌在医学、农业和环保领域中的危害。对其风险和在生物防治领域的发展前景做了评价和展望。

英文摘要：

Biological control agents,especially Pseudomonas fluorescens ,have become one of the most impor-tant and useful options for plant disease management.This study reviews the culture characteristics of P .fluo-rescens ,including the morphological characteristics,physiological and biochemical characteristics,culture con-ditions and the similarities or differences with other bacteria also isolated from various plant groups to control diseases.The disease control efficiency of P .fluorescens when used alone or together with other bacteria or treatment preparations is summarized.The modes of action of both P .fluorescens and bio-active substances used for controlling plant diseases are elucidated.Hazards of P .fluorescens in medicine,agriculture and envi-ronmental protection are discussed.The outlook and prospects for biological control in the field are also evalua-ted and a field risk assessment presented.
