摘要：
Seeds of Glycine max (soybean) were inoculated with N-fixing bacterium Bradyrhizobium japonicum and grown in growth chamber to investigate interactive effects of atmospheric CO(2) and plants Nitrogen status on root and shoot length and biomass, nodule formation and Nitrogen concentration. Plants were grown with CO(2) at 3500 and 1000ppm with or without Bradyrhizobium japonicum inoculation. Root and shoot length and dry mass of Glycine max increased significantly with CO(2) enrichment provided with Bradyrhizobium japonicum as compared to deficient Nitrogen fixing bacterium. While ambient and enriched CO(2) levels resulted in increased Nitrogen concentration of Glycine max shoot and root which is inoculated with N-fixing bacterium. Nodule formation was also enhanced in plants supplied with Bradyrhizobium japonicum as compared to plants which is Bradyrhizobium japonicum deficient at both CO(2) concentrations.
