- Number of trees = 10. D, stem diameter at 1.3 m above the ground; ARW, annual ring width; WFL, wood fiber length; VEL, vessel element length; BD, basic density; AD, air-dry density after drying at around 22 °C and 65% relative humidity for 2 weeks (11.3 ± 0.5% of moisture content); DMOE, dynamic Young’s modulus; MOE, modulus of elasticity; MOR, modulus of rupture; U, absorbed energy in impact bending; CS, compressive strength parallel to grain; SS, shearing strength of small clear specimens. Values in left and right sides of diagonal show correlation coefficients and significant correlations p values. Correlation coefficients with bold style indicate correlation coefficients with p value less than 0.05
