Se estudio la variacion de la densidad y dimensiones de las traqueidas en madera de dos procedencias de pino romeron de ocho anos y tres clases de diametro. En secciones transversales de seis arboles por procedencia, en la base, altura del pecho (AP) y 25, 50 y 75% de la altura total, se extrajeron secciones diametrales para determinar la densidad en su primera mitad, en submuestras a 25, 50, 75 y 100% de la longitud del radio. En la segunda mitad se seleccionaron las maderas temprana y tardia…

Caracterización anatómica y variabilidad de los componentes de la madera de Calycophyllum spruceanum (Benth). Hook.
TLDR
The anatomical characteristics, radial and longitudinal variation of the anatomical constituents of Calycophyllum spruceanun (Benth) Hook of a plantation from the Peruvian Amazon were evaluated and it was found that fiber length, wall thickness, tangential pore diameter and vessel length increased significantly towards the cortex; while the frequency of pores decreased.
Wood anatomy of Colombian Podocarpaceae (Podocarpus, Prumnopitys and Retrophyllum)
TLDR
There was remarkable uniformity in the characteristics of the six species of Colombian Podocarpaceae, although some differences in quantitative traits were found.
A MONOGRAPHIC REVISION OF RETROPHYLLUM (PODOCARPACEAE)
TLDR
Six living species of the genus Retrophyllum C.N. Page (Podocarpaceae) are revised and the typification of Nageia minor comprehensively discussed in an appendix, a key to the six species recognised is given.

Propiedades Físico-Mecánicas y Usos de Dos Especies de Podocarpus (P. rospigliosi Pilger; P. montanus var Meridensis Bucholz y Gray)
Las propiedades fisicas y mecanicas de las maderas son una de las principales caracteristicas que determinan los usos mas convenientes que deben darse a cada una de ellas. El objetivo del presente
Wood Formation from the Base to the Crown in Pinus Radiata: Gradients of Tracheid Wall Thickness, Wood Density, Radial Growth Rate and Gene Expression
TLDR
Differences in the rate of cambial cell division, differences in the rates and duration of tracheid wall thickening, and differences in gene expression underpin the gradients of wood properties found in pines.
Wood Quality of Sugi (Cryptomeria Japonica) Grown at four initial Spacings
TLDR
The dynamic Young's modulus, the modulus of rupture, and themodulus of elasticity in static bending increased with the decrease in the initial spacing, which affected the lumber quality of sugi wood.
Axial and Radial Variations in Xylem Anatomy of Angiosperm and Conifer Trees in Yunnan, China
TLDR
Axial and radial changes in xylem characteristics of six angiosperm tree species and three coniferous tree species in Yunnan, China indicated that the number of conducting vessels increases from trunk to twig as they become narrower, and axial trends in conduit lumen diameter and number were consistent with the WBE model.

Effects of crown size on wood characteristics of Corsican pine in relation to definitions of juvenile wood, crown formed wood and core wood
Summary Current use of the terms ‘juvenile wood’, ‘crown formed wood’ and ‘core wood’ is confusing: some authors have used the terms synonymously, while others have used each term in a more
Radial Variation in the size of Axial Elements in Relation to Stem Increment in Quercus Serrata
TLDR
Results indicate that earlywood vessel lumen diameter is the best indicator of the three anatomical properties tested and that a relationship exists between the maturation ages of the size of axial elements and radial stem increment.
Formation and Properties of Juvenile Wood in Southern Pines: A Synopsis
To satisfy the increasing demand for forest products, much of the future timber supply will be from improved trees grown on managed plantations. This fast-grown resource will tend to be harvested in
Radial Variation of Fiber Length Increment in Acacia Mangium
TLDR
The results of the cross-correlation function between wood fiber length increment and climatic factors showed that fiber lengths responded to changes in precipitation with a time lag of between zero to four months.
