Phenotypic characterization of 15 H. parviporum isolates and virulence validation of two selected isolates. a Mortality rate of Norway spruce seedlings infected by 15 Heterobasidion parviporum isolates and the control at 15 and 25 dpi. b Percentage of wood dry mass losses caused by 15 H. parviporum isolates and the control. c Norway spruce clone C30560 infected by S15 and S12 as well as wounded control in phloem and xylem in virulence validation.
