摘要
经济林病害影响和制约着我国经济林产业的发展,生物防治因对环境和人类健康友好而备受关注。目前生防菌已被广泛应用于植物病害的生物防治,其通过对病原菌的竞争作用、重寄生作用、拮抗作用和对植物的促生作用、诱导抗性作用达到病害防治的效果。植物精油则通过影响病原菌细胞壁、细胞膜的合成及功能,干扰其呼吸与能量代谢、遗传物质的合成及相关功能调控、生物膜的功能及群体感应系统达到抑制病原菌的效果。综述了经济林病害中生防菌抑制病原菌的拮抗机理与精油抑菌机理,为经济林病害生物防治提供科学依据,并展望了低成本、高效率的植物精油抑菌剂在经济林病害生物防治中的潜力。
Non-wood forest diseases affect and restrict the development of non-wood forest industry in China.Biological control has attracted more attentions for its friendliness to environment and human health.At present,biological control agents have been widely used,which can control diseases through the competition for nutrients,hyperparasitism and production of antibiotics against phytopathogens,and the stimulation of plant growth and induction of host defense mechanisms.Plant essential oils could inhibit pathogens by affecting the synthesis and function of cell wall and cell membrane of pathogens,interfering with respiration and energy metabolism of pathogens,synthesis of genetic material and related function regulation,function of biofilm and quorum sensing system.The antagonistic mechanism of biocontrol agents against pathogens and the inhibitory mechanism of plant essential oil were reviewed to provide reference for biological control of non-wood forest diseases.The potential of low cost and high efficiency plant essential oil in biological control of non-wood forest diseases was also prospected.
