The virulence of Heterobasidion parviporum population from Norway spruce stand in Suwałki Forest District

Abstract

 

The aim of this study was to determine the virulence of H. parviporum genets with known genetic similarity and representing pathogen’s population, which infested a part of Norway spruce stand. Genets caused average 47% mortality of spruce seedlings in infection experiment in vitro. The mortality rate varied from 16% to 80%. In infection experiment in vivo the mycelium of H. parviporum caused the wood necrosis on distance from 0.8 to 7.78 mm. 56% of genets of investigating population characterized by high virulence, 22% by average and 22% by low virulence.
