Abstract

Inoculation test with three isolates of dieback fungus Guignardia cryptomeriae with different virulence was conducted into Cryptomeria japonica trees to investigate whether inoculum dosage influenced the size of canker lesion and wood discoloration. Toothpicks containing fungal hyphae were inoculated into the trunk of four trees of 13 years old. These trees were harvested and put to investigation one year after the inoculation. The size of wound made by sterilized toothpicks (control) affected the axial expansion of cambial necrosis, but not the expansion of wood discoloration. In the case of inoculation with fungal isolates with varying virulence, the inoculum dosage did not give any influence to the size of cambial necrosis and wood discoloration.
