Abstract

The effect of inoculation of wheat plant seeds by cells of 2 endophytic strains of Bacillus subtilis on the formation of endomycorrhiza in the roots under salt stress was studied. It was found that the indicators of mycorrhization of plant roots decreased both during salt stress in the soil and during seed treatment with endophytic bacteria. At the same time, under conditions of salt stress, an increase in mycorrhization rates was found in plants inoculated with B. subtilis. It was revealed that B. subtilis bacteria reduced stress in plants resulting from soil salinization. The obtained results showed the possible nature of the simultaneous relationship of plants with representatives of two kingdoms – bacteria and fungi. Probably, under conditions of stress action on the host plants, it is more profitable for all 3 participants of the symbiotic system to survive together, preserving the reproductive potential for the next generations.
