Figure 5From: The influence of moisture content variation on fungal pigment formation in spalted woodPigment production in beech (b) and sugar maple (sm) by Xylaria polymorpha (average of three strains) at various moisture content values in ten weeks of incubation: ezl – external zone lines; ep – external pigmentation; izl – internal zone lines; ip – internal pigmentation. Error bars represent one standard deviation of five replicates per set. Different letters represent significant differences at α = 0.05 within each category.Back to article page
