Seed treatments with Bacillus cereus UW85 increased nodulation of soybeans in three field seasons and in three different sterilized soils in the growth chamber. In the field, 28 and 35 days after planting, UW85-treated plants had 31 to 133% more nodules than untreated plants. From 49 days after planting until seed harvest, there were no significant differences between nodulation of UW85-treated plants and untreated control plants. In the growth chamber, in sterilized soil-vermiculite mixtures, at 28 days after planting, UW85 seed treatments enhanced nodulation by 34 to 61%, indicating that the increase in nodulation was not dependent on the soil flora.
用蜡样芽孢杆菌UW85进行种子处理，在三个田间季节以及在生长室的三种不同灭菌土壤中，均增加了大豆的根瘤形成。在田间，种植后28天和35天，经UW85处理的植株比未处理的植株根瘤多31%至133%。从种植后49天到种子收获，经UW85处理的植株与未处理的对照植株在根瘤形成方面没有显著差异。在生长室中，在灭菌的土壤-蛭石混合物中，种植后28天，UW85种子处理使根瘤形成增加了34%至61%，这表明根瘤形成的增加不依赖于土壤菌群。
