ABSTRACT:
Study samples were collected at six sites in the Węgierka Zwykła plum orchard at five different time points (from April to October 1999). Quantitative and qualitative composition of microflora inhabiting plum trees significantly depended on their occurrence in soil and air. Qualitative microbial analysis revealed the presence of 30 species of bacteria, 20 species of yeasts and 60 cultures of moulds. The highest counts in the samples were found for microorganisms of the genera Micrococcus, Staphylococcus, Rhodotorula, Cladosporium, Penicillium and Trichoderma. Yeast strains belonging to the genera Rhodotorula, Candida and Debaryomyces, Aerobasidium, and filamentous fungi of Rhizopus nigricans species, characterised by relatively good ability of fermentation of many sugars, dominated on tree surface.
