Fig. 1From: Energetics of the distribution of cell wall in wood based on an eigenvalue analysisRelationship between shrinkage and wood density under air-dry conditions. Black line indicates the regression line. Samplings of similar wood density were performed from within gray rectangle area. Typical optical micrographs of the transverse section are depicted for the low and high-shrinkage samples. Scale bars represent 5Â mmBack to article page
