Significant difference of anatomical wood properties among initial tree density zoning symbols were examined (Tukey HSD)
ns no significant difference (p ≥ 0.05), DE-J in the row of RW means that ring width in J trees were significantly different from those in D tress and E trees (p < 0.05). RN ring number, RW ring width, LP latewood percentage, AWD average wood density, EWD earlywood density, LWD latewood density, MFA(E) MFA of earlywood tracheids, MFA(L) MFA of latewood tracheids
