Plant and Soil Mechanisms of Plant Resistance to Cd Toxicity under Application of Plant Growth Promoting Rhizobacterium in Soil Contaminated with Heavy Metal

Plant and soil mechanisms of barley plant resistance to Cd toxicity as influenced by the plant growth-promoting rhizobacterium P. fluorescens 21 were studied in a series of pot experiments on artificially Cd-contaminated gray forest soil. It has been established that the application of the bacterium improved the growth of plants and eliminated the toxicity of the heavy metal due to enhancing barrier functions of the plant root system and barrier functions of the soil.
