| description | The anatomical characteristics, physical properties, mechanical properties and air-drying speed were determined for the wood of five trees of Quercus sideroxyla Humb. & Bonpl. (red oak) and two of Quercus rugosa Nee (white Oak), collected in three municipalities of the State of Durango. For the macroscopic anatomical study specimens of 12 cm x 7 cm x 1 cm were used and for the microscopic anatomical study, thin slices were cut and used along with fragmented material. Histochemical tests were carried out to determine tannins. The measurable elements were classified based on the average. They included the taxonomic position, morphological characteristics, geographic and altitudinal distribution and common names. The technological characteristics were determined in green and dry conditions, using specimens of various dimensions. The wood of the seven individuals, presented similar characteristics in some cases and different in others between subgenera and differences between individuals of the same subgenus were recorded. The physical characteristics of both species are classified as high to very high; the mechanical properties in both green and dry conditions are classified as hard, stiff and strong in the majority of the cases, with the notable exception of the strength in compression parallel of the two species and shear parallel of Q. rugosa which is moderately strong. The results were compared with data available in the literature for both species, coinciding in many characteristics with the studied in the present work. Based on the results suggested applications are given. |

Se determinaron las características anatómicas, físicas, mecánicas y de velocidad de secado al aire libre de la madera de cinco árboles de Quercus sideroxyla Humb. & Bonpl. (encino rojo) y dos de Quercus rugosa Née (encino blanco), recolectados en tres municipios del estado de Durango. Para el estudio anatómico macroscópico se usaron muestras de 12 cm x 7 cm x 1 cm y para el anatómico microscópico se hicieron laminillas fijas de cortes y de material disociado. Con pruebas histoquímicas se determinaron taninos. Los elementos mensurables se clasificaron con base en la media. Se incluye la posición taxonómica, características morfológicas, distribución geográfica y altitudinal y nombres comunes. Las características tecnológicas se determinaron en condición verde (saturada) y en condición seca (12% de contenido de humedad), usando probetas de diferentes dimensiones. La madera de los siete individuos, presentó características semejantes para unos casos y diferentes para otros entre subgéneros y diferencias entre individuos del mismo subgénero. Las características físicas de ambas especies se clasifican como altas a muy altas; las propiedades-mecánicas tanto en condición verde como en seca, se clasifican como duras, rígidas y resistentes para la mayoría de los casos, con la notable excepción de la resistencia en compresión paralela para las dos especies y en cortante paralelo para Q. rugosa que es moderadamente resistente. Los resultados se compararon con lo disponible en la literatura para ambas especies, coincidiendo en muchas características con las estudiadas en el presente trabajo. Con base en los resultados se sugieren usos.
