ANATOMICAL AND CHEMICAL PROPERTIES OF JUVENILE Schizolobium amazonicum WOOD [PDF]

Revista Árvore, 2018
ABSTRACT The objective of this study was to determine the effects of tree age and of pith-bark and base-top positions on anatomical characteristics, and the effect of age on the chemical components of Schizolobium amazonicum (Paricá wood). The material was obtained from commercial plantations in the states of Maranhão and Pará with ages of 5, 7, 9 and ...

ESTIMATION OF AGE OF SEGREGATION OF JUVENILE AND MATURE Carya illinoinensis (Wangenh) K. Koch WOOD USING ANATOMICAL CHARACTERISTICS

Ciência Florestal, 2010
Knowledge of the demarcation of juvenile and mature wood is essential both for wood technology and forest management. Thinning, in most cases, must take into account this parameter, as the juvenile wood has inferior characteristics compared to mature ...

Effects of crown size on wood characteristics of Corsican pine in relation to definitions of juvenile wood, crown formed wood and core wood [PDF]

Forestry, 2002
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 restricted sense to imply the region of a log where wood structure and properties are influenced by ring number from the pith (or distance from it), or by crown ...

Relationships between microfibril angle, modulus of elasticity and compressive strength in Eucalyptus wood

Maderas: Ciencia y Tecnología, 2012
Many traits are known to be important in determining the value of Eucalyptus wood as sawn timber. The commercial importance of the microfibril angle (MFA) for wood quality is well established for a range of softwoods, but is less clear for hardwood ...
