The susceptibility of various spruce species to Rhizosphaera kalkhoffii and some cultural characteristics of the fungus in vitro

摘要

AbstractTemperature and pH requirements for mycelial growth and conidial germination were investigated for variousRhizosphaera kalkhoffiiisolates. Conidial germination was also tested on spruce needles. Some factors of host susceptibility were determined using needle extract agar and buffer‐capacity of needle sa
