A study of the population structure of the Hyphomycetes and prokaryotic organisms was conducted in the years 2001-2003. An exact experiment was performed in a randomized split-plot design, in four replications. Fungi of the genus Penicillium were the dominant species, which accounted for 44% and 22.3% of all isolates in cv. Sakwa and cv. Roma, respectively. Much higher counts of bacteria of the genus Pseudomonas were isolated from the rhizosphere of winter wheat cv. Roma than from the rhizosphere of cv. Sakwa. The population size of bacteria of the genus Pseudomonas and of the order Actinomycetales depended on the development phase of wheat plants.
