Morphological study of fibers of four trees of Eucalyptus saligna implanted in Concordia, Entre Rios, Argentina

Eucalyptus saligna is native to the East and Southeast of Australia. It is included in the Symphomyrtus group together with E. grandis and E. deanei. Originally, Eucalyptus saligna was mistaken for E. grandis in Argentina .The work was done on four trees planted at INTA in Concordia, Province of Ent...

It is included in the Symphomyrtus group together with E. grandis and E. deanei. Originally, Eucalyptus saligna was mistaken for E. grandis in Argentina .The work was done on four trees planted at INTA in Concordia, Province of Entre Rios, with discs removed at four different heights. Circular pieces have been cut and prepared to be observed under microscope by maceration and cutting sections. Fiber length, width and wall thickness were measured, and fieltrability coefficient was calculated - measuring 200 fibers or more from each sample. Results were: fiber length, 966 - 772; width, 14.4 - 13.1, and thickness, 2.7 - 2.9 - all expressed in microns-; and the fieltrability coefficient, 71 - 57. Values compared with those of Eucalyptus grandis were similar, except for fiber length which was 10% shorter and fiber width, resulting 9% thinner. Eucalyptus saligna es oriundo del este y sudeste de Australia. Se ubica en el grupo Symphomyrtus junto con E. grandis y E. deanei. Inicialmente se lo confundió en la Argentina con E. grandis. Se trabajó con cuatro árboles implantados en el INTA de Concordia Entre Ríos, con rodajas extraídas a cuatro alturas. Se cortaron sectores circulares que se prepararon para la observación microscópica, obteniéndose disgregados y cortes de secciones. Se midieron longitud, ancho y espesor de pared de fibra y se calculó el coeficiente de fieltrabilidad, midiendo 200 fibras o más de cada muestra. Las longitudes dieron entre 966 y 772, anchos entre 14,4 y 13,1, espesores de pared entre 2,7 y 2,9 (todos expresados en micrones) y el coeficiente de flexibilidad entre 71 y 57. Los valores comparados con los de Eucalyptus grandis fueron similares, a excepción de la longitud y el ancho de fibra que resultaron 10% y 9% menores, respectivamente.
