The objective of this study was the investigation of the resistance of modifiedwood against sapstaining fungi and the investigation of the influences of fungalgrowth. Specimens of Scots pine sapwood (Pinus sylvestris L.) and Beech wood(Fagus sylvatica L.) were investigated after being treated with an amino-alkylfunctionaloligomeric siloxane, a sodium water glass solution and 1,3-dimethylol-4,5-dihydroxyethylene urea (DMDHEU).The following is a structured outline of this study:Laboratory tests for the resistance against the blue stain fungusAureobasidium pullulansThe objective was to develop a laboratory test method against blue stain formodified wood as well as the determination of the resistance against blue stain.After definition of a suitable test method, the laboratory tests displayed animproved resistance against blue stain for all tested modified wood specimens.Regardless of the wood species, the fungal infestation was reduced but notinhibited. Among the treated specimens, the water glass treated specimensshowed the lowest, the siloxane treated specimens the highest infestationrespectively.
