Fig. 4From: Improving aboveground biomass estimates by taking into account density variations between tree componentsRelationship 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 < 0.001Back to article page
