| 摘 要： | 植物根际促生菌是一类可以显著提高植物生活力或植物抗病害能力的天然土壤细菌,除可经由多种途径促进植物的营养吸收与物质积累、提高植物的各项生长参数与生理生化指标外,其还可通过多种途径对植物病害加以防治.根际促生菌的生物防治活性依赖于其在植物根际的定殖,并经由特定生防活性物质的分泌、对植物系统抗性的诱导来加以实现.利用根际促...

| Abstract: | Plant growth promoting rhizobacteria (PGPR) is a type of soil bacteria that can enhance plant growth and disease resisting ability. Besides improving nutrients’ absorption, plant substance accumulation, and promoting various growth parameters of physiological and biochemical indexes of plants, PGPR can also protect plants from diseases in various ways. The biological control activity of PGPR relies on the colonization of plant rhizosphere, which is realized by the secretion of specific biological control active substances and the inducing of systemic resistance of plants. The rhizosphere colonization of PGPR can inhibit pathogens, which is crucial to the control of some plant diseases that are difficult to be realized by chemical agents. This paper discusses the biological control mechanism of PGPR, and the possibility of using PGPR as biological control agent for plant diseases, which might provide new views for the ecological agriculture development. |
