title: [Isolation of endophytic bacteria in potato and test of antagonistic action to bacterial ring rot of potato].
abstract: In this study, two hundred and forty bacterial strains were isolated from inner tissue of potato tubers collected from DaTong, TaiYuan and Inner Mongolia Autonomous regions. On the basis of antagonistic examination in vitro, fifty and five bacteria strains were characterized for antagonistic bacteria to ring rot of potato. It was 22.9 percentage of all bacteria strains. The biggest radius of suppression circle was 13 mm. Nine strains were chosen for their suppression of bacterial ring rot, blackleg and dry rot of potato. These strains were bacteriologically ideatified. Strain 118 was Pseudomonas fluorescens biovar V. Strain 110 was Bacillus pumilus. Strain 085 was Bacillus stearothermophilus. Strain 069 was Erwinia herbicola. Strain 043 was Xanthomomas fragariae. Strain 116 was Curtobacterium. Strains A-10' and T3 were Bacillus. Strain H1-6 was Pseudomonas fluorescens.
