摘要
植物内生真菌具有普遍存在性和生物多样性,许多种类在植物体内作为生防菌,能有效地防治植物病害,增强植物对病原菌的抗性。鉴此,综述了植物内生真菌在植物病害生物防治中的作用,从其分泌抗菌物质、与病菌竞争生态位和营养物质、诱导系统抗性、产生植物激素等方面分析植物内生真菌的生防机制,并对其作为植物病害生防因子进行开发与应用中存在的问题进行了讨论。
Plant endophytic fungi are of universal existence with biodiversity.Some of those species are used as biocontrol agents and effectively control plant diseases and enhance resistance of plants to pathogens.The roles of endophytic fungi in biological control of plant diseases are reviewed.The biocontrol mechanisms include their secretion of antimicrobial substances,competition of niche and nutrients with bacteria,induction of systemic resistance,production of plant hormones,etc.In addition,several problems in research and application of plant endophytic fungi as biocontrol agents are discussed.
