Effects of endophytic bacterial strain BS-2(Bacillus subtilis) on rice seedling growth and its mechanism were investigated. Results were as f ollows: when the rice was inoculated with the bacterial suspension of 10~3 cfu ·mL~-1, the bacteria coul d colonize its inside; the bacteria, the bacterial culture suspension or its dilutions, and the secretion of the bacteria could acc elerate growth of rice seedlings at different degrees, for example, the fre sh weight and dry weight of the plant were increased; the bacteria also could i ncrease the content of the rice chlorophyll, enhance action of protection enzyme , advance resistance to adversity by improving adjustability, and promote the gro w th of rice seedlings.
