Conversion between basic density and apparent density at any moisture content in Eucalyptus grandis
(Walter De Gruyter Gmbh, 2014-12-01)
Wood basic density (BD) is related to other wood characteristics and its determination is important in forest inventory, though BD must be differentiated from the apparent density (AD), which relates to the moisture content ...
DENDROMETRIC AND CHEMICAL TRAITS AND BASIC DENSITY WOOD OF Eucalyptus grandis X Eucalyptus urophylla HYBRIDS
(Centro Pesquisas Florestais, Ufsm, 2016-01-01)
The present study evaluated the dendrometric, chemical and basic density wood from five hybrids of Eucalyptus grandis x Eucalyptus urophylla at 2.25 years old. The experiment was implemented in 3.5 x 2 meters spacing, with ...
Tropical woods: influence of density in hardness parallel and normal to the grain for some Brazilian tropical tree species
(IPEF-INST PESQUISAS ESTUDOS FLORESTAIS, 2010)
The aim of this work is to verify the possibility to correlating specific gravity and wood hardness parallel and perpendicular to the grain. The purpose is to offer one more tool to help in the decision about wood species ...
WOOD DENSITY VARIATION AND TREE RING DEMARCATION IN Gmelina arborea TREES USING X-RAY DENSITOMETRY
(UNIV FEDERAL LAVRAS-UFLA, 2009)
Due to its relationship with other properties, wood density is the main wood quality parameter. Modern, accurate methods - such as X-ray densitometry - are applied to determine the spatial distribution of density in wood ...
Functional relationships between wood structure and vulnerability to xylem cavitation in races of Eucalyptus globulus differing in wood density
(Oxford University Press, 2018-02)
Wood density can be considered as a measure of the internal wood structure, and it is usually used as a proxy measure of other mechanical and functional traits. Eucalyptus is one of the most important commercial forestry ...
X-ray Microdensitometry Applied to Determination of Wood Density Variation of Eucalyptus grandis W. Hill trees
(IPEF-INST PESQUISAS ESTUDOS FLORESTAISPIRACICABA, 2012)
This study aimed to analyze the variation of wood density in the radial and longitudinal trunk of Eucalyptus grandis trees. Six 23 years old trees were selected and cross sections were cut in three longitudinal positions ...
Multivariate association of wood basic density with site and plantation variables in Eucalyptus spp.
(2020-01-01)
Wood density, an important parameter for evaluating forest biomass productivity and wood product quality control, is influenced by a complex combination of variables of forest plantations, including environmental conditions ...
Density as estimator of dimensional stability quantities of Brazilian tropical woods
(2017-08-01)
Wood is a material widely used in various sectors of construction, such as in structures and building components. The volume of wood extracted from tropical forests has reached a considerable amount, and this wood is ...
Physical and chemical changes in juvenile and mature wood of shizolobium parahyba caused by thermal modification
(2020-01-01)
In the Brazilian Atlantic Forest, the pioneer species Schizolobium parahyba, known as guapuruvu, is a fastgrowing tree with potential for ecological restoration in forest management projects. However, an undesirable feature ...
