An increasing problem of Spruce bark beetle (Ips typographus) attacks on softwood, particularly Norway spruce (Picea abies) has lead to a situation where there is a large stock of beetle …
Recently, German spruce forests had been severely affected by a bark-beetle calamity (2018 – 2024), which put forth a calamity area of > 500 000 ha (BMEL 2024). In Germany, …
Norway spruce wood exhibits structural variations in its different tissue types. The main part of the tree consists of earlywood, which forms at the beginning of the growing season and …
Properties of tracheids are related to the usability of wood for different end-products in pulp and paper industry and in sawmill. Tracheid morphology is correlated with, e.g., optical and physical …
Norway spruce (Picea abies) is widely used not only in Norway but in many other European countries. Due to its refractory behavior after drying it is difficult to impregnate with …
In this study, raw material potential of Norway spruce (Picea abies (L.) Karst.) entailed by sorting of pulpwood was studied. The objective was to examine what kinds of groups could …
The moisture content (mc) of wood is of great importance to several processes in mechanical pulp mills. Debarking, chipping, refining and indirect bleaching are factors that are affected by the …
Plant oils have significantly higher thermal conductivity than air, thus conducting heat more effectively to the surface and into wood. Although known for long time, drying in oil under vacuum …
The gravimetric method that is used today to determine the moisture content in wood is very tedious. The results are received after 24 hours, and it can be quite hard …
In this study the moisture content of Norway spruce stump wood after harvesting was examined. The material was collected immediately after harvesting at the clear cutting area and after different …
Coated specimens of fast-grown and slow-grown Norway spruce (Picea abies (L.) Karst) and of Scots pine heartwood (Pinus Sylvestris L.) were subjected to liquid water exposure based on the European …
Development of surface moulds and staining fungi on painted spruce panels with known origin and wood properties was investigated over a period of 4 years. Materials of Norway spruce (Picea …
The study is based on data from the first 6 sites of a 14 sites survey, covering a range of growing conditions in south-eastern Norway. The timber was strength-graded with …
The aim of this preliminary study was to investigate differences in mechanical and fungicidal properties of three different wood species (English oak (Quercus sp.), common beach (Fagus sylvatica) and Norway …
Wood properties depends on different biotic and abiotic factors what are mainly effecting wood physical and mechanical properties. The same time the wood quality is changing. However, essential lost in …
