Relationship between L* value and moisture content in heartwood in 40-year-old Japanese cedar trees. r, correlation coefficient; **, significant at 1% level. Samples were categorized into three groups based on the results of moisture content measurements. The six individuals with the highest and the six individuals with the lowest moisture content were categorized in the HMC (closed circles) group and the LMC (open circles) group, respectively. The remaining eight individuals were classed as “others” (open diamonds)
