摘要

During 1997–1999 the health condition of Sorbus aucuparia L. in the urban environment of the town Nitra was evaluated in relation to the type of usage or location of the trees, and occurrence, spread and harmfulness of the parasitic fungus Cytospora rubescens Fr. The developmental stages of the fungus in field and laboratory conditions, the virulence and growth rates of the mycelium isolated from trees of different usage or location was determined. The degree of damage by C. rubescens to S. aucuparia in Nitra was determined. No direct relation between degree of damage and the content of nine elements in the fungus C. rubescens was found.
