Notably, contrasting patterns of radial variation of WD have been demonstrated and are related to regeneration guilds (light-demanding vs. shade- bearing) but haven't been demonstrated to be related to leaf phenology (deciduous vs. evergreen). With the destructive method and the “archimed” principle, we investigated the WD radial variation of nine timber tree species harvested in the eastern region of Cameroon. The result showed that WD differed significantly among these nine species (P > 0.05). Keywords: wood density, radial variation, tropical forest, shade tolerance, leaf phenology, congo basin.
