Аннотация:Composition of yeast communities in fruits of hedge rose (Rosa canina L.) was investigated during all ontogenetic periods from primordium to fruits' destruction. Yeasts were found to be numerous and diverse not only on surface of fruits but also inside. The whole number of yeasts inside fruits gradually increased during ripening and was maximal in winter before their destruction. Species composition of yeasts inside fruits and on fruit's surface was similar. The dominant species were represented by Cryptococcus albidus and related filobasidious species, Cystofilobasidium capitatum, Metschnikowia pulcherrima and Hanseniaspora guilliermondii. The relative abundance of these species changed during fruits ripening, and each species was characterized by its own type of dynamic. The abundance of basidiomycetous yeasts was higher on fruit's surface while as-comycetous yeasts were more numerous inside ripe fruits. So the outgoing of ascomycetous yeasts inside fruits in winter is assumed to be the strategy to escape negative factors.
