Effects of plant growth regulators (PGRs) and rhizobia on nodule number and nitrogenase activity. A Influence of PGRs (gibberellin A3 [GA3] and mepiquat chloride [MC]) and inoculation with rhizobia (Sinorhizobium fredii and Bradyrhizobium japonicum) on the nodule number of soybean roots. B Influence of rhizobial inoculation combined with PGRs (GA3 and MC) on the nitrogenase activity of soybean roots. Each bar is the mean of eight measurements of nodule number and nitrogenase activity. Student’s t test was used to evaluate the difference between the control and the treatments
