Fig. 9

Variations of basic specific gravity (BSG) with relative radius at 1.3 m height for Abies alba and Pseudotsuga menziesii, and at 2 m height for Fagus sylvatica, Acer pseudoplatanus and Quercus petraea/robur. Each point represents the average of one 1 cm-thick tangential band; each grey curve represents one tree; the coloured solid lines show the LOESS smoothing for each species
