| description | The anatomical characteristics of the wood of Pinus arizonica Engelmann, P. cooperi C. E. Blanco, P. durangensis Martínez, P. herrerae Martínez, P. leiophylla Schlecht. & Cham. and P. teocote Schlecht. & Cham are presented. The study material was obtained from two to four trees per species collected in pine-oak forests in the municipalities of Santiago Papasquiaro, San Dimas and Durango, in the state of Durango, Mexico. To observe the microscopic characteristics, slices of 20 µm in thickness were cut and stained with rapid green-safranin or with astra blue-basic fuchsine and dissociated material stained with Bismarck brown. For the macroscopic characteristics, specimens of 7 cm × 5 cm × 1 cm were produced. The proportion of early-wood is three times greater than that of late-wood in all of the specimens; the values of wall thickness and lumen diameter differed between early and late wood. Radii and axial resin canals presented differences in size and abundance. Pinus herrerae presents the widest rings and P. leiophylla and P. teocote the narrowest. The macroscopic characteristics of the six species studied are generally similar among individuals of the same species, regardless of collection site. Wood color and grain are influenced by the proportions of early and late woods present in each ring and the width of those characteristics. Pinus arizonica and P. cooperi presented differences in color between the sapwood and heartwood. The results are presented in tables and illustrated with photographs. |

Se presentan las características anatómicas de la madera de Pinus arizonica Engelmann, P. cooperi C. E. Blanco, P. durangensis Martínez, P. herrerae Martínez, P. leiophylla Schlecht. & Cham. y P. teocote Schlecht. & Cham. El material de estudio para cada especie se obtuvo de dos a cuatro árboles por especie recolectados en bosques de pino-encino en los municipios de Santiago Papasquiaro, San Dimas y Durango, del estado de Durango, México. Para las características microscópicas se hicieron cortes de 20 µm de grosor que se tiñeron con safranina-verde rápido o con fucsina básica-azul de astra y material disociado teñido con pardo de Bismark. Para las características macroscópicas se elaboraron tablillas de 7 cm x 5 cm x 1 cm. La proporción de madera temprana es tres veces mayor que la madera tardía en todos los ejemplares. Los valores del grosor de la pared y el diámetro del lumen entre madera temprana y tardía son diferentes. Los radios y los canales resiníferos axiales y radiales presentaron diferencias en su tamaño y su abundancia; P. herreraepresenta los anillos más anchos P. leiophylla y P. teocote los más angostos. Las características macroscópicas de las seis especies son similares entre individuos de la misma especie independientemente del sitio de recolección, en términos generales. El color y el veteado están influenciados por la proporción de madera temprana y tardía presente en cada anillo y la anchura de los mismos. P. arizonica y P. cooperi presentaron diferencia de color entre albura y duramen. Las especies estudiadas tienen características que las hacen muy útiles y representan un valioso recurso para la entidad.
