Effect of rhizospheric bacteria on the growth and heavy metal accumulation in plants grown on soils under technogenic loads
The study has been focused on the impact of rhizospheric bacteria Azotobacter and Bacillus from bio-preparations Azotobakterin, Fosfobakterin, and Kremnebakterin on the distribution of heavy metals (Pb, Cd, Co, Ni) and As in agricultural crops (lettuce, radish), as well as on plant growth and development on technogenic soils with different pollution levels. A difference in the effect of rhizospheric bacteria on plant morphogenesis and heavy metals accumulation in plants under different technogenic loads has been shown. The ratio of heavy metals accumulation in plants decreased with bacterization on a strongly polluted soil, which can be of significant practical importance in the application of bacterial techniques in agroproduction on technogenic soils.
