Structure of soil complexes of microscopic fungi under different varieties of broad beans

Considering of broad beans as an integral component of biological crop rotations, the presence of phytopathogenic, toxigenic, opportunistic, and allergenic microscopic fungi in soils under their different varieties should be examined. At the Botanical garden BelSU (Belgorod) on a natural infectious background were grown and studied of 16 different broad beans varieties. Were taking into account the indicators of frequency of occurrence and abundance of species, they determined the structures of soil mycocomplexes under different varieties. Analysis of the data showed that most micromycetes in the rhizosphere under bean varieties belonged to the Ascomycota division, which is part of it as 4th classes of Sordariomycetes, Dothideomycetes, Eurotiomycetes and Saccharomycetes. The species diversity of the soil mycobiota of steaming soil was characterized by 26 species, and under the studied bean varieties 57 species of fungi were identified. In the mycocomplex under varieties, species of different ranks of frequency of occurrence developed that were not noted in the paring soil: Alternaria tenuissima and Stemphyllium solani were rarely and accidentally found in the control soil, but they were not found in under the beans during budding - flowering...
