Values are presented as mean; ± standard deviation;
mean that the same letters are not significantly different at a p-value of 0.05 according to Duncan’s new multiple range test;
= p < 0.05;
SL = significance level; ns = non significant; RHW = red-colored heartwood tree; BHW = black-colored heartwood tree; SW = sapwood; HW = heartwood; T = tangential direction; and R = radial direction.
