Relationship between mean annual ring width until boundary annual ring number between core wood and outer wood, and annual ring number from the pith of the boundary. Number of trees = 10. Mean annual ring width (ARW) until annual ring number of the boundary was calculated by averaging the annual ring width from the first to boundary ring number in each tree listed in Table 4
