Abstract
The results of study of pathogenic mycobiota biodiversity of Viola L. leaves of the collection of the Central Siberian Botanical Garden, SB RAS are presented in the article. The composition of Viola L. leaf pathogenes involving 8 species has been determined for Western Siberia for the first time. Pathocomplexes are described. The micromycetes Ascochyta violae , Cercospora violae , Phyllosticta violae and Septoria violae form the basis of pathogenic complexes. Similarity measure of micromycetes composition of the plant leaves is assessed. More than half of comparison variants showed a reliably high similarity of the mycobiota (KSC = 1.0-0.6). It has been established that, under studied conditions, pycnidial fungi formed sporulation organs of different degrees of ripeness towards the end of vegetation period.
