| description | Some relationships between ray proportions, strength and shrinkage properties and basic density in hardwood species were highlighted. A better understanding of their relationships caused by the variation in moisture content in the hygroscopic domain could be a key factor in determining of wood stability properties and to determine the choice of a specific wood species according to its service life condition. The objectives of this study were (i) to determine the physical properties of various ring porous wood species (ii) and to evaluate the influence of wood rays (according to their proportions and volume) on physical properties of wood and more particularly on the Transverse Anisotropy Ratio for Shrinkage (TARS). This study focused on four ring-porous hardwood species; Castanea sativa, Quercus canariensis, Quercus petraea and Quercus robur, differing by the presence and abundance of their multiseriate wood rays. Basic densities, tangential shrinkages, radial shrinkages and the TARS of heartwood and sapwood from each wood species were determined. Wood-rays’ proportions and volume were measured by the image analysis method, and their influence on the last three shrinkages was investigated. A significant correlation between wood ray proportions, wood shrinkage values and basic density was observed. |

Se destacaron algunas relaciones entre las proporciones de los radios, las propiedades de resistencia y contracción y la densidad básica en especies de madera de angiospermas. Una mejor comprensión de sus relaciones causadas por la variación en el contenido de humedad en el dominio higroscópico podría ser un factor clave para determinar las propiedades de estabilidad de la madera y para determinar la elección de una especie de madera específica de acuerdo con su condición de vida útil. Los objetivos de este estudio fueron (i) determinar las propiedades físicas de varias especies de madera porosa anular (ii) y evaluar la influencia de los radios de madera (de acuerdo con sus proporciones y volumen) en las propiedades físicas de la madera y más particularmente en la relación de anisotropía transversal por contracción (TARS, por sus siglas en inglés). Este estudio se centró en cuatro especies de angiospermas de porosidad anular: Castanea sativa, Quercus canariensis, Quercus petraea y Quercus robur, que se diferencian por la presencia y abundancia de radios multiseriados en su madera. Se determinaron las densidades básicas, las contracciones tangenciales, las contracciones radiales y la relación TARS de duramen y de albura de la madera de cada especie. Las proporciones y el volumen de los radios de madera se midieron con el método de análisis de imágenes, y se investigó su influencia en las últimas tres contracciones. Se observó una correlación significativa entre las proporciones de los radios, los valores de contracción y la densidad básica.
