El objetivo del trabajo fue caracterizar la madera de Ziziphus mistol Griseb. y establecer relaciones entre la albura y el duramen. Fueron seleccionados 15 árboles al azar y apeados. Las muestras fueron obtenidas a la altura de 1,3 m (DAP). Se adoptó la terminología del Comité de Nomenclatura de la IAWA y Tortorelli. El conteo y medición de anillos se efectuó con el Equipo Computarizado ANIOL y el programa CATRAS. La relación albura/duramen fue analizada en función de la edad. Se aplicó el método de la llama y colorantes para la diferenciación albura/duramen. La madera se caracteriza por los siguientes rasgos anatómicos: porosidad difusa, vasos predominantemente solitarios, pequeños, muy numerosos, con punteaduras intervasculares alternas, radios 1-3 seriados, heterogéneos, parénquima paratraqueal vasicéntrico, aliforme, en bandas delgadas; fibras cortas con paredes muy gruesas. El espesor de la albura representa el 75% del diámetro del tronco, para un intervalo de 80 años, incrementándose con la edad, hasta un valor de 35 anillos para luego permanecer constante. El duramen presenta la obstrucción total de los vasos por sustancias gomosas.
The objective of this work was to characterize the wood of Ziziphus mistol Griseb. and set relationships between its sapwood and heartwood. Fifteen trees were randomly selected and felled. The samples were obtained at 1,3 m above ground (DBH). The nomenclature by the IAWA Committee and Tortorelli were adopted. Both the tree ring counting and measuring were performed with the ANIOL Computer Equipment and the CATRAS software. The sapwood/heartwood relationship was analyzed in terms of age. The flame and coloring methods were applied for differentiating sapwood/heartwood. The following anatomical features were used to characterize the wood: diffuse porosity, predominantly isolated, small, quite numerous vessels having alternate intervascular pits, heterogeneous, 1-3 rays seriate, aliform, vesselcentric paratracheal parenchyma, in narrow bands. The sapwood thickness accounts for 75% of the trunk diameter, in an 80 year range, that increases with age up to 35 rings remaining constant afterwards. The heartwood shows gummy-substances caused total vessel obstruction.
