Correlation between weight loss (WL %) by Poria placenta (Poria placenta Coocke sensu J. Erikson (PP) [Fries, FPRL 280] and Lighteness L*, for different heat treatments on Norway spruce (Picea abies Karst.). Treatment temperature (°C) is indicated for each process. For each treatment intensity, Lighteness L* from colour measurement was correlated with WL. From Welzbacher et al. (2008), with permission
