Variability in density of spruce (Picea abies [L.] Karst.) wood with the presence of reaction wood

Journal of Forest Science, 2007
The study was aimed to assess the integral value that determines wood properties - wood density at a moisture content of 0% and 12%. The wood density was researched in a sample tree with the presence of reaction compression wood.

Wood density variations of Norway spruce (Picea abies (L.) Karst.) under contrasting climate conditions in southwestern Germany [PDF]

Annals of Forest Research, 2013
We analyzed inter-annual variations in ring width and maximum wood density of Norway spruce (Picea abies (L.) Karst.) at different altitudes in Baden-Württemberg, southwestern Germany, to determine the climate response of these parameters under ...

Physical properties of four ring-porous hardwood species: Influence of wood rays on tangential and radial wood shrinkage [PDF]

, 2019
Some relationships between ray proportions, strength and shrinkage properties and basic density in hardwood species were highlighted. A better understanding of their relationships caused by the variation in moisture content in the hygroscopic domain ...

Modelling the variation in wood density of New Zealand-grown Douglas-fir

New Zealand Journal of Forestry Science, 2017
Background Wood density is an important property that affects the performance of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) timber. In order to develop strategies to achieve certain end-product outcomes, forest managers and wood processors ...

Spatial variation of wood density for Eucalyptus grandis by near infra red hyperspectral imaging combined with X-ray analysis [PDF]

, 2019
Most near-infrared spectroscopy (NIRS) studies for wood density use multiple spectral acquisitions taken manually at several points from pith to bark.

Systematic Review: Climate and Non-Climate Factors Influencing Wood Density in the Boreal Zone

BioResources, 2023
Wood density is a crucial factor in determining the quality of wood in boreal ecosystems within the Northern Hemisphere. Climate variables play a significant role in shaping wood density, posing challenges for forest managers and stakeholders in the wood

Variability of European beech wood density as influenced by interactions between tree-ring growth and aspect

Forest Ecosystems, 2016
Background: Wood density is considered to be the most important predictor of wood quality but despite its importance, diffuse-porous tree species have been the subject of only a limited number of studies.

Influence of production variables and starting material on charcoal stable isotopic and molecular characteristics [PDF]

, 2008
We present a systematic study on the effect of starting species, gas composition, temperature, particle size and duration of heating upon the molecular and stable isotope composition of high density (mangrove) and low density (pine) wood.
