Laboratory Investigations of Mold Growth on Transverse and Longitudinal Wood Surfaces

The possible influence of anatomical sections wood on mold growth was investigated by means a laboratory experiment. selected fungi, Aspergillus sp., Penicillium and Alternaria sp. were inoculated spraying the surface specimens prepared from pine (Pinus sylvestris) spruce (Picea abies). incubation carried out under stable environmental conditions (temperature 22 °C, relative humidity 75, 87, 95%) over three months. Mold evaluated based regular microscopic macroscopic observations. recorded coverage fractions qualitative indicators development later expressed dimensionless index. differences in found to be relatively insignificant. In contrast, comparison measured data with other experimental studies showed large differences, especially initial phase. discrepancy is probably related among protocols. It concluded that would improved if common standardized methodology developed followed.
