Abstract:
Two PGPR strains A21-4 and HG28-5 were used as materials,the effect of two PGPR on emergence,growth and rhizosphere soil microbial ecology of pepper,and its root colonization activity were studied adopting plug experiment.The results showed that seed inoculation with A21-4 and HG28-5 were all significantly enhanced the emergence potential,increasing rates 40.54% and 37.84%;At the same time,A21-4 and HG28-5 were all significantly promoted seedling growth,chlorophyll content and root activities.Increasing chlorophyll content rates were 65.49% and 43.66%,improving root activities 77.91% and 55.81%;Moreover,A21-4 and HG28-5 were all significantly enhanced the soil enzyme activities,and increased the organic matters and available P contents on the rhizosphere soils.Especially,inoculation with A21-4 could improve the urease activity 66.01%,and increase the organic matter content 66.62%;Inoculation with HG28-5 could improve the phosphatase activity 88.16%,increase the available P content 67.53%.Inaddition,A21-4 and HG28-5 were all successfully colonized on the rhizosphere soil and roots of pepper.The colonization ability were 2.15×105 cfu/cm and 4.75×105 cfu/cm in the DLF test,in the plug experiment,A21-4 and HG28-5 were persisted on root of pepper with a relative high population density which were more than 105 cfu/cm and 106  cfu/cm,persisted on the rhizosphere soils were more than 104 cfu/cm and 105 cfu/cm,respectively.
