摘要应用植物根际促生菌（PGPR）促进植物生长和防治土传病害主要是在集约化种植的农田中。在园艺集约栽培系统中，由于高施肥量，通常导致土壤盐渍化。因此，高浓度的无机盐积累在植物根际可能是一个因素，盐胁迫影响根系和根相关的根际细菌。在以前的报告（Matsuguchi和Sakai 1995）中，我们观察到高盐度的土壤引起菠菜根中荧光假单胞菌数量的显着减少。此外，高盐度的土壤的不利影响是更明显的荧光假单胞菌菌株比恶臭假单胞菌菌株，导致在根中的荧光假单胞菌的组成的改变，其中VP。putida}占优势。本研究的目的是..
Abstract Use of PGPR (plant growth-promoting rhizobacteria) for stimulating plant growth and for the biological control of soil-borne diseases is necessary mainly in fields with intensive cropping. The intensive cultivation systems in horticulture have generally led to soil salinity due tp the high rates of fertilizer application. Therefore, the high concentration of inorganic salts accumulated in the plant rhizosphere is likely to be a factor of salinity stress affecting both roots and root-associated rhizobacteria. In a previous report (Matsuguchi and Sakai 1995), we observed that high salinity of soil had induced a significant decrease in the populations of fluorescent pseudomonads in spinach roots. Furthermore, the adverse effect of high salinity of soil was more pronounced on Pseudomonas fluorescens strains than on Pseudomonas putida strains, resulting in an alteration of the composition of fluorescent pseudomonads in the roots where vP. putida} predominated. The objective of the present study was to...
