“…Accordingly, species with larger average leaf area exhibited higher LWR than those with smaller leaf area. The leaf area seems to be a good explanatory variable of biomass allocation patterns because it defines not only the extent of interception of radiant energy, but also the absorption of CO 2 , and facilitates the transfer of water between foliage and atmosphere (Margolis et al 1995, Leuchner et al 2012, Weraduwage et al 2015. Our results reinforce the importance of leaf traits for plant performance .…”

Mensah, S., Glèlè Kakaï, R., Seifert, T., 2016. Patterns of biomass allocation between foliage and woody structure: the effects of tree size and specific functional traits. Ann. For. Res. 59(1): 49-60.Abstract. Biomass allocation is closely related to species traits, resources availability and competitive abilities, and therefore it is often used to capture resource utilisation within plants. In this study, we searched for patterns in biomass allocation between foliage and wood (stem plus branch), and how they changed with tree size (diameter), species identity and functional traits (leaf area and specific wood density). Using data on the aboveground biomass of 89 trees from six species in a Mistbelt forest (South Africa), we evaluated the leaf to wood mass ratio (LWR). The effects of tree size, species identity and specific traits on LWR were tested using Generalised Linear Models. Tree size (diameter) was the main driver of biomass allocation, with 44.43 % of variance explained. As expected, LWR declined significantly with increasing tree diameter. Leaf area (30.17% explained variance) and wood density (12.61% explained variance) also showed significant effects, after size effect was accounted for. Results also showed clear differences among species and between groups of species. Per unit of wood mass, more biomass is allocated to the foliage in the species with the larger leaf area. Inversely, less biomass is allocated to the foliage in species with higher wood density. Moreover, with increasing diameter, lower wood density species tended to allocate more biomass to foliage and less biomass to stems and branches. Overall, our results emphasise the influence of plant size and functional traits on biomass allocation, but showed that neither tree diameter and species identity nor leaf area and wood density are the only important variables.

“…Some studies have indicated that leaf area/sapwood relationships are site specific and affected by stand treatment histories while other studies have found only minor effects of these factors [14]. There is also some evidence that leaf area/sapwood relations can vary over the geographic range of a species [15,22] LAIs presented in this study should be viewed with caution because of the non-local origin of the leaf area/sapwood coefficients for Norway spruce and the broadleaf species, and the different methodologies used to develop the leaf area/sapwood coefficients for Norway spruce and Scots pine.…”

“…Los datos para calibrar el crecimiento y producción del modelo se obtuvieron de la literatura (García y Tella 1986, Puertas 2003). La biomasa de las raíces no se ha estimado en el campo, así que se asumió que las raíces representan una parte constante de la biomasa aérea de los árboles (Margolis et al 1995), Tras una exhaustiva revisión bibliográfica no se encontraron valores para pino silvestre en los Pirineos, y dado que las relaciones de biomasa aérea/subterránea en el gé-nero Pinus están centradas en un rango estrecho de valores (Richarson 1998), se utilizaron datos publicados de esa relación (Malkönen 1974, Litton et al 2003. La simulación de la limitación de nutrientes se limitó al nitrógeno, el nutriente limitante en estos bosques .…”
