Abstract:
Direct and inoculation methods indicated high concentrations of bacteria on the following plants: Carex nigra, Eriophorum vaginatum, Drosera rotundifolia, and Ledum palustre. The correlation between bacterial abundance, species, and organs of the studied plants was revealed. Proteobacteria were shown to predominate in the phyllosphere, while bacilli and actinomycetes prevailed in rhizoplane and rhizosphere. Members of the genera Pseudomonas and Erwinia predominated in the phyllosphere. High values of the nitrogen-fixing activity of bacterial populations in the rhizosphere were revealed, which reached a maximum in the rhizosphere under sundew.
