Anatomía comparada de leño y corteza de Geoffroea striata y Geoffroea decorticans

| description | Two are the arboreal species of the genus Geoffroea that vegetate in Argentina: Geoffroea striata Morong (manduvi-rá) and Geoffroea decorticans Burkart (chañar). Both have floristic importance, are used locally but their woods have no commercial value. The objectives of this work are: to describe the wood and bark anatomy of Geoffroea striata and contribute to their knowledge, to compare it anatomically with Geoffroea decorticans. The material was collected from natural forests of Isla del Cerrito Locality in Chaco (Chaco eastern district) and Los Flores, in Santiago del Estero ( Chaco western district). Five trees of each species were selected at random, obtaining a disc of 5 cm from the trunk at 1,3 m. In wood descriptions the IAWA Nomenclature was used. Bark descriptions were made according to standards of tissues distribution and the terminology of Roth. It may be Concluded that Geoffroea striata is a tree of great anatomical affinity with Geoffroea decorticans, being susceptible to have an alternative use of its wood. The variables present in the wood having meaningful differences are: vessel length, number of pores/mm2; fiber external and internal diameter, fiber wall thickness, as well as ray length. In bark, the principal differences reside in the external aspect. Both species present evolutionary characters in wood and bark. |

En Argentina vegetan dos especies arbóreas del género Geoffroea: Geoffroea striata Morong (manduvi-rá) y Geoffroea decorticans Burkart (chañar). Ambas tienen importancia florística, son usadas localmente pero sus maderas no tienen valor comercial. En este trabajo se describen la madera y la corteza de Geoffroea striata y para contribuir a su conocimiento, se realiza anatomía comparada con Geoffroea decorticans. El material fue colectado en el bosque natural de la Localidad Isla del Cerrito en Chaco (distrito chaqueño oriental) y de Los Flores, en Santiago del Estero (distrito chaqueño occidental). Se seleccionaron al azar cinco individuos de cada especie, obteniéndose una rodaja de 5 cm del tronco a 1,3 m del suelo. Para las descripciones del leño o madera se usó la terminología establecida por el Comité de Nomenclatura de IAWA. Las descripciones de corteza se realizaron según los criterios de distribución de patrones de tejidos y la terminología de Roth. Se concluyó que Geoffroea striata es una especie de gran afinidad anatómica con Geoffroea decorticans, pudiendo tener un uso alternativo su madera. En el leño las variables con diferencias significativas son: longitud de vasos, número de vasos/mm2; diámetro externo, interno y espesor de pared de fibras, así como la longitud de radios. En la corteza, las principales diferencias residen en el aspecto externo. Ambas especies presentan caracteres evolutivos en corteza y madera.
