Wood density within Norway spruce stems

Silva Fennica, 2008
We studied the variation in average wood density of annual rings, earlywood density, and latewood density in addition to ring width and latewood percentage within Norway spruce (Picea abies (L.) Karst.) stems from the pith to the bark, and from the ...

Temporally resolved intra-annual wood density variations in European beech (Fagus sylvatica L.) as affected by climate and aspect [PDF]

, 2012
We investigated the temporal variability of intra-annual wood density variations in European beech (Fagus sylvatica L.) in a valley in southwestern Germany. Samples were collected from 11 beech trees growing at north-west (NW) and south-west (SW) exposed

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 ...

Applications of CrAlN ternary system in wood machining of Medium Density Fibreboard (MDF) [PDF]

, 2009
Nowadays, medium density fibreboard (MDF) composite wood is more and more used in the furniture industry to replace bulk wood such as oak, beech, etc. Indeed, this material presents good mechanical properties, is easy to machine, homogeneous, exists in ...

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.

Predicting wood density of growth increments of Douglas-fir stands in New Zealand

New Zealand Journal of Forestry Science, 2018
Background Douglas-fir comprises 6% of New Zealand’s planted forest area and contributes to the national carbon sequestration estimate. Carbon stock changes in Douglas-fir stem wood can be calculated by multiplying the increment in stem volume under bark

Relationships Between Wood-Anatomical Features and Resistance Drilling Density in Norway Spruce and European Beech

Frontiers in Plant Science, 2022
Environmental conditions affect tree-ring width (TRW), wood structure, and, consequently, wood density, which is one of the main wood quality indicators.
