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 1×10(8) 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.
对内生细菌 Azospirillum sp. 菌株 B510 的接种实验，该菌株是从田间生长的水稻表面消毒茎中分离出来的，在温室盆栽和日本北海道的稻田中进行。B510 在温室条件下显著促进了新生成叶片和地上部生物量的生长。当水稻幼苗用 1×10(8) CFU ml(-1)处理，然后移栽到稻田中时，分蘖数和种子产量显著增加。Azospirillum sp. 菌株 B510 是一种很有前途的细菌接种剂，可用于促进植物生长和农业实践。
