[Actinomycetes in the rhizosphere of barley plants grown in the strongly acidic soddy podzolic soil].
The study of various factors (soil acidity, the variety of barley plants, and their developmental phases) on the rhizosphere actinomycete complex showed that it is soil acidity that substantially influences the population of rhizosphere actinomycetes. The effect of soil acidity was most likely due to the different tolerance of rhizosphere actinomycetes to high concentrations of the aluminum and hydrogen ions. The developmental phases of barley plants correlated with the population indices of only one genus of actinomycetes, Micromonospora.
