Growth Traits Slash Pine Pulpwood Properties Wood Density
2023/6/5
Slash pine (Pinus elliottii) is the most important and a fast-growing material that is used for industrial timber and pulp production. A breeding program of slash pine that aims to improve wood proper...
Influence of site conditions and silvicultural practice on the wood density of Scots pine (Pinus sylvestris L.) – a case study from the Doksy locality, Czech Republic
shelterwood regeneration clearcut forest site softwoods physical properties variability
2018/3/6
After spruce, the Scots pine (Pinus sylvestris Linnaeus) is the second most important commercial coniferous tree
species in the Czech Republic. However, we are finding out that awareness of the varia...
Variation of wood density in Turkish hazel (Corylus colurna L.) grown in the Czech Republic
Corylus colurna L wood density variability
2015/4/14
The aim of this study was to investigate the wood density of Turkish hazel (Corylus colurna L.), an introduced species in the Czech Republic. Sample trees coming from a Czech site were tested for basi...
The relation between the microscopic structure and the wood density of European beech (Fagus sylvatica L.)

Stem wood density (SWD) of young Norway spruce trees (Picea abies [L.] Karst.) growing at ambient (A variant, 350 μmol(CO2)/mol) and elevated (E variant, A + 350 μmol(CO2)/mol) atmospheric CO2 concent...
Effects of Seed Origin and Site on Wood Density of Sitka Spruce（Picea sitchensis（Bong.）Carr.）Grown in Britain
Seed Origin Site Wood Density Sitka Spruce Plantations
2009/1/13
Since density may have a direct influence on wood properties and because density is a factor under genetic control, this study details the effects of seed origins and sites on density. In addition to...
Comparative Study of Wood Density by Specific Amount of Void Volume（Porosity）
Wood density Porosity Moisture content Green volume method Oven dry method Maximum moisture content method
2009/1/13
Various methods were progressively investigated to determine wood density within the most reliable void volume (porosity) values. Three softwood species of Bornmulleriana fir (Abies bornmulleriana Mat...
