MONTES DE OCA-CANO, E.; GARCIA-RAMIREZ, P.; NAJERA-LUNA, J. A.  y  MENDEZ-GONZALEZ, J.. Fitting biomass equations for Pinus durangensis in the region of El Salto, Durango. Rev. Chapingo ser. cienc. for. ambient [online]. 2009, vol.15, n.1, pp.65-71. ISSN 2007-4018.

The objective of this study was to formulate linear and nonlinear equations to estimate biomass by component, for leaves, branches, stem and total, for trees from three to ten years old, in the region of El Salto, Dgo. The results indicate that the work best at the Individual level. The total component shows the best statistical adjustment, whereas the greates variations are found in the branch and stem components. In addition percentage of biomass is analyzed by component where it is observed that the stem contributes 46.9 % of the biomass, the leaves 35.6 % and the branches only 17.3 % of the total biomass. Within the age range analyzed, the biomass in the stem increases by 2.96 % annually, the biomass in the leaves decreases by 3.13 % and the biomass in the branches increases by 0.17 %.
