THE VIRULENCE OF HETEROBASIDION PARVIPORUM POPULATION FROM NORWAY SPRUCE STAND IN SUWAłKI FOREST DISTRICT

Keywords: Heterobasidion parviporum, genets, virulence, Norway spruce
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.
