Population of entophytic bacteria in maize roots and its dynamic analysis

Abstract

Abstract: In 2001～2002,14 maize cultivars in Liaoning Province were used for the analysis of their entophytic bacteria population.The entophytic bacteria strains with a higher frequency in maize roots were Bacillus spp.,Enterobacter spp.,Serratia spp.,Pseudomonas spp.,Xanthomonas spp.,Clavibacter spp.,Bacillus spp.,Enterobacter spp.and Serratia spp.Comparatively,Bacillus spp.was the most prevalent entophytic bacterium,including 8 species,B.subtilis,B.megaterium,B.cereus,B.licheniformis,B.anthracis, B.mycoides,B.pumilus and B.circulans,and with an average isolation frequency of 75.5% at seedling stage and 77.6% at adult stage.There existed significant differences in the population and dynamics of endophytic bacteria among maize cultivars and growth periods,and a significant correlation was found between maize genetic background and entophytic bacteria population.

Key words: Maize, Entophytic bacteria, Population, Dynamic analysis, Genetic background
