| description | In order to study if mechanical elements are involved in conduction, relationships between wood anatomical variables and functional relations were analyzed. For this purpose canonical correlation analysis was performed. Vessel area, diameter and length were selected as the dependant set to represent xylem conductivity, and fiber diameter, length and wall thickness as well as fiber percentage as the independent set, associated to mechanical elements, assuming that they are involved in conduction too. Results showed that both sets of variables were highly correlated showing the association between conduction and mechanical systems. Aspidosperma quebracho-blanco has specialized xylem to avoid water stress. Solitary vessels provide efficient water conduction, while tracheids and fiber-tracheids provide a subsidiary system responsible also of water movement. In this species xylem works as an interconnected network in which conductive and resistance systems are interrelated. |

Se analizó la asociación entre variables anatómicas del leño y las relaciones funcionales en el xilema de Aspidosperma quebracho-blanco para estudiar si los elementos asociados con la resistencia mecánica también intervienen en la conducción. Para ello se utilizó el método de correlaciones canónicas. Se seleccionaron las variables área, diámetro y longitud de elementos de vasos como variables del conjunto dependiente para explicar la conducción y las variables diámetro, espesor de pared, longitud y porcentaje de fibras como variables del conjunto independiente asociadas a la resistencia con el supuesto de que ellas también intervienen en la conducción. Los resultados mostraron que ambos conjuntos están altamente correlacionados denotando la asociación entre los sistemas de conducción y la resistencia mecánica en el xilema. El quebracho blanco presenta un xilema muy especializado para tolerar el estrés hídrico. Los vasos solitarios proporcionan eficiencia en la conducción mientras que las traqueidas vasicéntricas y fibrotraqueidas forman un sistema subsidiario e intervienen también proporcionando seguridad en la conducción. En esta especie el xilema funciona como de una red interconectada.
