Fig. 6From: Patterns of within-stem variations in wood specific gravity and water content for five temperate tree speciesBasic specific gravity (BSG) for the outer area vs the inner area at 1.30 m height for softwood species, and 2 m for hardwood species. Each point represents a tree. Larger circles show the barycentre of each species. The solid diagonal line is the 1:1 lineBack to article page
