Gostota lesa - metode določanja in pomen pri razvoju gozdno lesnega biogospodarstva

open access: yesActa Silvae et Ligni, 2021
Wood density is an important physical property that can be easily measured and is closely related to many other wood properties. Furthermore, wood density is a good indicator of the usability and applicability of wood in the wood processing, construction

Allocation of Wood Density in European Oak (Quercus robur L.) Trees Grown under a Canopy of Scots Pine [PDF]

open access: yes, 2021
The allocation of wood density in trees depends on many factors, but mainly on the tree species. A great number of studies have analysed wood density in dominant or codominant trees, but only a few have focused on trees grown under canopy.

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

open access: yesJournal 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.

Effect of wood density and cracks on the moisture content of coated Norway spruce (Picea abies (L.) Karst) [PDF]

open access: yes, 2019
A protective coating is often used on the cladding of wooden facades to limit the absorption of moisture. Low wood moisture content (MC) is essential to obtain satisfactory durability performance. Wood density is known to influence the water sorption and

Wood density within Norway spruce stems

open access: yesSilva 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]

open access: yes, 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
