ROJAS GARCIA, Fabiola  and  VILLERS RUIZ, Lourdes. Comparación de dos métodos para estimar la densidad de la madera de Pinus hartwegii Lindl. del Volcán La Malinche. Madera bosques [online]. 2005, vol.11, n.1, pp.63-71. ISSN 2448-7597.  https://doi.org/10.21829/myb.2005.1111262.

In order to consider the wood specific gravity of Pinus hartwegii in the La Malinche volcano two methods were used: the traditional one of the maximum moisture content (Smith, 1954) and the empirical method proposed recently (Valencia and Vargas, 1997); 22 small piecess wood were extracted with a Pressler drill, to which both methods were applied. The average values, standard deviation, minimum and maximum of the wood density were very similar. It was determined that the specific gravity of the wood was 0,496 g/cm3. It was demonstrated with a simple correlation that the results of both methods were very close to 1,0. The Pinus hartwegii wood is classified as moderately heavy. The specific gravity value obtained in this study can be used for biomass estimations of the wood from this species.

Keywords : Specific gravity; empirical method; maximum moisture method; Pinus hartwegii; Pressler drill.
