Development of blue stain in mechanically harvested Scots pine (Pinus sylvestris) logs during storage

Abstract: Blue stain is a type of discoloration that considerably lowers the aesthetic qualities of wood. During harvesting, fungal inoculum finds its way into the wood through places of cutting, delimbing, and damage to the tree stem. The development of peripheral blue stain in the logs of Scots pine (Pinus sylvestris L.) due to damage by a harvester head was investigated, using logs felled and delimbed with a chainsaw as reference. The development of blue stain was related to the age class of the stand, the date of fe… Show more

“…Melville) using a mechanised harvesting machine are much more susceptible to colonization by blue‐stain fungi than chainsaw‐processed logs and the study was done in absence of obvious bark beetle attack which would normally bring blue‐stain fungi associated with the beetle (Uzunović et al., 1999a). A similar pattern was recently found for Scots pine logs in Poland (Szewczyk et al., 2020). In addition, in the Polish investigation, the blue‐stain area developed in sapwood stored after spring felling was significantly less than that after summer felling.…”

“…The mean area of blue‐stain in wood stored after spring felling was significantly lower than that in wood stored after summer felling. In addition, the development of blue‐stain in logs was visible between the 6th and 9th weeks after spring felling and between the 3rd and 6th weeks after summer felling (Szewczyk et al., 2020). Most likely, favourable microclimatic conditions, especially air temperature, could profoundly affect the development of blue‐stain fungi in sapwood.…”
