Density of the microbial population on the roots of different barleyvarieties in acid and limed soddy-podzolic soils

摘要

A comparative evaluation of the number of microorganisms in the rhizoplane of different barley varieties in strongly acid and limed soddy-podzolic soils demonstrates that the ratio between populations of bacteria capable of growing in neutral and acid aluminum-containing media changes under stress differently in varieties with different resistance capacities. The relationship between the variety specificity with respect to bacterial complexes in the rhizoplane and the ability of the variety to alter the acidity in the root zone has been revealed.
