Relationship between the mean BD of tree components and the DBH of the tree for every tree species in unthinned (circles) and heavily thinned (triangles) plots. Stem w/o knots is the stem under bark without knots, Br ins are the branch insertions and Br w/o ins are the branches without their insertion. The regression line and the p value of the slope are indicated in the plot when it was significant. The stars indicate the p value significance: NS, p ≥ 0.05; *, p < 0.05; **, p < 0.01; ***, p < 0.001
