Understanding biological processes in forests is necessary to orientate ecosystem management towards potential C sequestration. To achieve this, information is required about changes in forest biomass C pools, including the stem components (bark, sapwood and heartwood).
This study aimed to determine whether there are differences in C concentration in axial and radial directions within stem biomass in Pinus nigra, Pinus pinaster and Pinus sylvestris.
Wood samples from a permanent plantation in northern Spain were examined for C concentration and wood bulk density.
The results showed that C concentration was higher in heartwood than in sapwood in the three species. Pinus
spp. sapwood C concentration increased along the stem, while the C concentration in heartwood tissue showed
the opposite behavior. In bark, Pinus pinaster showed a decreasing trend, in contrast to Pinus nigra and Pinus
sylvestris, where higher values were found at the base and top of the stem. Finally, wood bulk density decreased in heartwood, sapwood and bark areas when stem height increased. Estimating C content taking into account
different anatomical parts and heights is important in considering the specificity of the different parts because of
their potential commercial or ecological use in forest ecosystems.|
