Was studied the activity of oxidative-reducing enzymes in these systems. It was established that insufficient water supply had a negative influence on the processes of forming and functioning of the symbiotic apparatus of soybean, which was created with the participation of strains 646, 604k and Tn5 mutants 113, T21-2. Drought depressed the growth of root nodules, which led to a decrease in the nitrogen fixation activity of the symbiotic apparatus. It has been shown that the application of B. japonicum T21-2 for pre-sowing inoculation allowed formation of highly effective nitrogen fixing systems under optimum and insufficient water supply of plants compared with inoculation by rhizobial of other strains examined. An increase in the activity of ascorbate and guaiacol peroxidase in soybean roots and nodules, which was affected by water deficit compared to that which grew under optimal conditions was revealed. It has been established that the use of lectins, as a component of the inoculum suspension, irrespective of the level of water supply, changes the activity of antioxidant enzymes, which can confirm its significance in the regulation of soybean-rhizobial systems and the reaction of inoculated soybean plants in drought.
