    Inoculation experiments with the endophytic bacterium Azospirillum sp. strain B510, an isolate from surface-sterilized stems of field-grown rice, were conducted in pots in a greenhouse, and in paddy fields in Hokkaido, Japan. B510 significantly enhanced the growth of newly generated leaves and shoot biomass under greenhouse conditions. When rice seedlings were treated with 1×108 CFU ml-1, then transplanted to paddy fields, tiller numbers and seed yield significantly increased. Azospirillum sp. strain B510 is a promising bacterial inoculant for plant growth promotion and agricultural practices.
