[Effect of phytoregulator reglag on symbiotic properties of Bradyrhizobium japonicum 634b].

The influence of inoculation compositions on the basis of nodule bacteria Bradyrhizobium japonicum 634b and phytohormonal plant preparation Reglalg on formation, functioning and productivity of soybean-rhisobium symbiosis was studied in the vegetation and field experiments. It was shown, that the phytohormonal component of the composition increases the nodulation and nitrogenase activity of the Bradyrhizobium japonicum 634b and effectiveness of the symbiotic system.
