Diameter growth and wood density in African and Amazonian timber species.. Correlation between diameter growth (cm*yr-1) and wood density (g*cm-3) of selected timber species from Amazonia and West Africa (r = -0.81, significance level p = 0.0001, model: growth = 2.2455*exp(-2.5652*x)). Data from: Terminalia ivorensis, (T.i.), Brachystegia eurycoma (B.e.), B. cynometra (B.c.), Daniellia ogea (D.o.): Triplochiton scleroxylon (T.s.), Sterculia rhinopetala (S.r.) Nesogordonia papaverifera (N.p.), Trilepsium madagascariense (T.m.);): Swietenia macrophylla (S.m.), Cedrela odorata (C.o.): Amburana cearensis (A.c.), Cedrela odorata (C.o.Bol), Cedrelinga catenaeformis (C.c.); This study:Cariniana micrantha (C.m.), Caryocar villosum (C.v.), Manilkara huberi (M.h.). Growth data consists of mean values from 18 individuals or more. Wood density data: own measurements and those of the Global Wood Density Database.

The correlation between specific means of wood density and growth rates derived from tree ring studies is highly significant (r = 0.81, Fig 9).
