Özet

The influence of constant relative humidity and temperature conditions on mycelial growth and coremiophore formation by the timber disfiguring fungus Ophiostoma piceae was determined. The minimum relative humidity tolerated by O. piceae was found to be 93% - 94% under laboratory conditions on 2% malt extract agar and Sitka spruce sapwood, equivalent to a wood moisture content of 21% - 22% at 15°C. This figure corresponds with a previous observation that staining by this fungus only develops in stacked Sitka spruce timber stored in a Scottish sawmill yard when the mean relative humidity was in excess of 93%. Wood drying method did not significantly affect the extent of staining but may have modified the optimum temperature for fungal development on wood.
