| description | The objective of this research was to estimate basic wood specific gravity and its level of variation among biomass components of trees of several species of the genera Pinus and Quercus of northern Durango, Mexico. A total of 843 wood core sepecimens were taken at different heights and at different diameter sections from 113 trees. Fresh wood blocks of 2,5 cm x 2,5 cm x 2,5 cm were measured and once they were oven dried they were weighted to estimate the wood specific gravity. Results showed that the basic wood specific gravity was statistically different between biomass components along the diameter and height gradients (P > F = 0,0001) for trees of the genus Pinus unlike for trees of the genus Quercus. Mathematical evaluations show that wood cores for measuring the bole wood specific gravity must be taken at a height of 0,22H instead of the traditional height of 1,3 m at which it is conventionally evaluated. |

El objetivo de esta investigación fue el de estimar la densidad básica de la madera y su nivel de variación con la altura y el diámetro en árboles de varias especies de los géneros Pinus y Quercus del norte del estado de Durango, México. Para esto se tomaron 843 especímenes a diferentes alturas del fuste y en diferentes secciones diamétricas de un muestreo aleatorio en 113 árboles. Se elaboraron probetas con dimensiones de 2,5 cm x 2,5 cm x 2,5 cm. Los resultados muestran que la densidad básica es estadísticamente diferente entre los componentes de albura y duramen (P > F = 0,0001) y la altura relativa (P > F = 0,0001) del fuste en el género Pinus. Para el género Quercus no se encontraron diferencias estadísticamente significativas con los componentes de la madera o con la altura relativa. Los cálculos matemáticos indican que la densidad básica se debe de estimar a una altura dada por 0,22H y no como convencionalmente se hace a 1,3 m.
