Characteristics and physical properties of poplar woods from Río Negro, Patagonia Argentina
Poplar cultivation began in Northern Patagonia, mainly in the Rio Negro province, as windbreaks for the protection of horticultural and fruit crops in its irrigated valleys. At present there are 6000 km of linear length of forest curtains and about 900 ha of poplar plantations in that province. The...

| description | Poplar cultivation began in Northern Patagonia, mainly in the Rio Negro province, as windbreaks for the protection of horticultural and fruit crops in its irrigated valleys. At present there are 6000 km of linear length of forest curtains and about 900 ha of poplar plantations in that province. The wood is used chiefly for the manufacture of containers and packaging, and is also used in building, furniture industry, laminated wood (plywood) and cellulose paste. No information is available on the characteristics and properties of these woods, which would be necessary for optimizing its exploitation and maximizing its value for different uses. This study describes macro and microscopic characteristics and physical properties of the wood of three clones widely used in the area, P. nigra cv. thaisiana, P. alba var bolleana y P. x canadensis conti 12, obtained from five individuals for each clone from windbreaks in Allen, Rio Negro Province, Argentine Patagonia. Low density (< 0.40) and macroscopic characteristics of the wood of the three clones determine its quality for lamination, cellulose paste and container and packaging manufacture. They showed medium volumetric contraction (11.82%, 10.32% y 12.15%, respectively) and were placed among partially stable to lightly unstable woods (V: 0.36 - 0.37). High anisotropic indexes (A > 2.3) revealed low dimensional stability, indicating the need for adequate drying processes for its use in windows and linings. |

La populicultura en Norpatagonia, principalmente en la provincia de Río Negro, comenzó con el objetivo de establecer cortinas rompevientos para proteger cultivos frutihortícolas en sus valles irrigados. En la actualidad existen 6000 km de longitud lineal de cortinas y unas 900 ha de plantaciones en macizo de álamo en dicha provincia. El destino de la madera de estos álamos es principalmente la fabricación de embalajes, pero se utiliza también en la construcción, industria del mueble, debobinado y pasta celulósica. No existe información de características y propiedades de esta valiosa materia prima, que es necesaria para optimizar su aprovechamiento y maximizar su valor en diferentes usos. En este trabajo se describen características estéticas, algunas características microscópicas y propiedades físicas de la madera de Populus nigra cv thaisiana, P. alba var bolleana y P. x canadensis ‘conti 12’, a partir de cinco ejemplares adultos de cada especie, provenientes de cortinas rompevientos de la localidad de Allen, provincia de Rio Negro, Patagonia Argentina. La baja densidad (< 0.40) y las características estéticas de la madera de las tres especies determinan su calidad para debobinado, pasta celulósica y fabricación de envases y embalajes. Los valores de contracción volumétrica (11.82%, 10.32% y 12.15%, respectivamente) y del coeficiente de contracción (V: 0.36 - 0.37) indican su ubicación entre las maderas medianamente nerviosas (medianamente estables). Los índices de anisotropía altos (A > 2.3) revelan su baja estabilidad dimensional, indicando la necesidad de realizar correctos secados de la misma para su uso en aberturas y revestimientos.
