Some Wood Properties of 10-Year-Old Eucalyptus Camaldulensis Dehnh. In Three Diametric Classes
(2022-01-01)
Multipurpose forests are becoming more frequent, but research on wood is still needed to target it for adequate industrial consumption. However, such determination requires a knowledge of the seed provenance and planting ...
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 ...
Identification of endangered or threatened Costa Rican tree species by wood anatomy and fluorescence activity

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 ...
Potential of Hevea brasiliensis Clones, Eucalyptus pellita and Eucalyptus tereticornis Wood as Raw Materials for Bioenergy Based on Higher Heating Value
(Springer, 2019-12-01)
About 11% of the world's primary energy consumption comes from biomass. However, a continuing material deficit indicates the need to find suitable timber for use as bioenergy. In this context, this study aims to determine ...
Combining steam explosion with 1-ethyl-3-methylimidazlium acetate treatment of wood yields lignin-coated cellulose nanocrystals of high aspect ratio
(Springer, 2016-06-01)
Lignin-coated cellulose nanocrystals (CNCs) were extracted from the tropical wood Angelim Vermelho in a yield of 47 % based on wood cellulose content. The procedure combined a mild steam explosion process with a treatment ...
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 ...
Classification of CITES-listed and other neotropical Meliaceae wood images using convolutional neural networks
(Biomed Central Ltd, 2018-03-23)
Background: The current state-of-the-art for field wood identification to combat illegal logging relies on experienced practitioners using hand lenses, specialized identification keys, atlases of woods, and field manuals. ...
