The species belonging to the genera Cryptococcus and Hansenula with saturnian spores predominate in the rhizosphere of agricultural plants. The sporiferous strains of Debaryomyces, Hanseniaspora apiculata, Metschnikowia pulcherrima, and asporogenic Candida krusei and Trichosporon cutaneum prevail in the rhizosphere of wild plants. Candida krusei and Trichosporon cutaneum prevail in the rhizosphere of wild plants. The cultures of Rhodotorula, Candida krusei and Metschnikowia pulcherrima are typical of the phyllosphere of both cultural and wild plants. The phyllosphere of cultural plants contains also the asporogenic strains of Cryptococcus, Candida tropicalis, Trichosporon pullulans, Tr. cutaneum, and Hansenula, while Hanseniaspora apiculata and Saccharomyces cerevisiae predominate in the phyllosphere of wild plants. The yeast flora of the majority of studied plants is diverse and comprises 10--20 species (in cabbage, potato, linden, aspen, and pear trees). The rhizophere and phyllosphere of some plants contain only 2 to 4 yeast species (onion, hop, wild apple).
