Gmelina arborea is planted in large areas of forest with the objective of producing solid wood using well known silvicultural techniques and taking advantage of the properties of the wood quality of fast-growing tree species managed in short rotation systems. The aim of this study was to analyze the morphology and dimension of fibers from the pith to the bark in trees from fast growth plantations in northern Costa Rica.
The results indicate that fiber morphology is irregular in both diameter and shape; with 1 to 4 septa, abundant crystals deposited in fiber lumina and minutely bordered pits with oblique and non- vestured apertures. Fiber length, width and cell wall thickness increased with tree age in the early stages. Lumen diameter was not correlated with tree age.
Key words: Fiber width; lumen diameter; cell wall thickness; fiber length
Gmelina arborease planta en grandes áreas de bosques con el objetivo de producir madera sólida mediante el uso de técnicas silvícolas bien conocidas, así como para aprovechar las ventajas de las propiedades de la calidad de la madera de especies arbóreas de rápido crecimiento y manejadas por sistemas de rotación corta. El objetivo de este estudio fue analizar la morfología y dimensión de las fibras, desde la médula hasta la corteza, en los árboles de rápido crecimiento de las plantaciones del norte de Costa Rica. Los resultados indican que la morfología de la fibra es irregular, tanto en diámetro como en forma; con 1 a 4 septa, cristales abundantes que se depositan en los lúmenes de la fibra y con hendiduras minuciosamente bordeadas con orificios no cubiertos y oblicuos. La longitud y ancho de la fibra y el grosor de la pared celular se incrementaron con la edad del árbol en las etapas tempranas. El diámetro del lumen no se correlacionó con la edad del árbol.
Palabras clave: Anchura de la fibra; diámetro del lumen; grosor de la pared celular; longitud de la fibra
