Abstract

Rhizosphere is the portion of the soil that is influenced by the root system and rhizoplane is defined as the residue of soil adherent to the root surface. The main goal of this study was to determine the mycobiota in the rhizosphere and rhizoplane of Vitis labrusca cv. Isabel in Pernambuco, Brazil, by isolation and morphological identification of strains. A total of 271 samples, representing 31 species, were found in the rhizosphere. For the rhizoplane, 387 isolates and 27 species were obtained. In the rhizosphere of the V. labrusca, the most frequently identified genera were Aspergillus (11.6%), Fusarium (30%) and Penicillium (10.1%), and Aspergillus (31.5%), Fusarium (9.8%) and Trichoderma (27%) in the rhizoplane. The species most frequently isolated from the rhizosphere was the potential plant pathogen Fusarium oxysporum, but in the rhizoplane, Aspergillus japonicus, was most frequently isolated. Both species were found during the rainy as well as dry season, whereas overall species diversity changed between both seasons.
