Influencia de la situación geográfica y la fisiografía en la calidad de la madera de "Quercus robur" L.

Abstract

Se seleccionaron 35 robles procedentes de varias zonas de Galicia sobre los que se determinaron sus principales características dendrométricas así como las condiciones del entorno. Los árboles fueron apeados para obtener probetas de madera libre de defectos, con dimensiones normalizadas, en las que se determinó el peso específico. Se constató la variación del peso específico de la madera entre individuos, siendo éste mayor en el duramen. La variación entre individuos fue parcialmente atribuida a circunstancias ambientales, que influyen de forma diferente en el peso específico del duramen y en el de la albura. Las características ambientales más influyentes en el peso específico fueron el relieve y la localización geográfica, siendo inapreciable la influencia de las variables dendrométricas. En cuanto a la localización geográfica, la madera de roble es más ligera cuanto más al interior de Galicia, más al oriente y mayor sea la altitud. La variación de la calidad de la madera entre individuos y entre zonas justifica que esta especie sea una fuente de diversidad a conservar. La localización de determinadas estaciones para el cultivo del roble no garantiza la obtención de madera más uniforme para la industria, debido a la baja relación entre peso específico y factores ambientales.
