Fig. 3. Variations of branch traits of different plant sizes (DBH or tree height) with branch age for Pinus koraiensis. DBH, diameter at breast height; RPA, pith area-to-total cross-sectional area ratio; RPHA, phloem area-to-total cross-sectional area ratio; RRC, total resin canal area-to-total cross-sectional area ratio; RXA, xylem area-to-total cross-sectional area ratio; WD, wood density; WN, wood nitrogen content. *, p > 0.05; **, p > 0.01; ***, p > 0.001.
