Relationships between crown biomass components (b _C, g) (y axis) and stem biomass components (b _ST, g) (x axis), obtained from the destructive sampling data, for the dry and semiarid sites plotted as quadratic functions to illustrate the differences for the moderate (treatments T _{5 – 800}, T _{10 – 800} and T _5 + 10), high (treatments T _{5 – 9500}, T _{5 − 1600} and T _{10 − 1600}) and very high (non-thinned plots T _C) tree density groups
