Prior to the era of impregnated timber, the heartwood of two boreal conifers, Scots pine (Pinus sylvestris L.) and Siberian larch (Larix sibirica Ledeb.), was used in construc-tions prone to …
There is large variation in wood characteristics, which contradicts the expectations of the consumers for the uniform quality. For example in Scots pine (Pinus sylvestris L.), heartwood timber is more …
We studied the effect of decay on the water adsorption capacity and the concentration of extractives of Scots pine (Pinus sylvestris L.) heartwood by comparing corresponding properties of decayed and …
The natural durability of wooden structures subjected to decay has become more important along with increasing concern about the ecological impacts of wood preservation chemicals. The fact that wood is …
Extractives of bark, heartwood, knots and wounded xylem provide defense for living trees. In Scots pine (Pinus sylvestris L.) heartwood the most important groups of defensive extractives are stilbenes, which …
Heartwood is dead tissue rich of extractives. Those extractives, especially stilbenes pinosylvin and its’ monomethylether, protect products made of heartwood against decay. Individual trees differ strongly from each other in …
New recepies for timber preservatives as well as new timber modification methods are being invented in order to prolong the service life of wooden constructions in out-of-doors applications. There is …
The poster presents the main ideas and some results of the five year project funded by Finnish Forest Cluster strategic centre (Finnish Bioeconomy Cluster, FIBIC, from 2012). Our study concentrated …
Stilbenes, phenolic compounds rich in Scots pine (Pinus sylvestris L.) heartwood, have strong fungicidal properties. We studied the effect of stilbene extract as an impregnant for Scots pine sapwood in …
To exploit and breed naturally extractive-rich heartwood of Scots pine (Pinus sylvestris L.) cost-effective high-throughput techniques to measure the heartwood compounds are needed. We compared traditional wet-chemistry analyses of phenolic …
The aim of the project is to develop and experiment optical technology and related software to measure the extractive content of Scots pine, Pinus sylvestris L., heartwood. The technology is …
Fast and accurate methods are needed to measure durability related chemical characteristics from solid wood. In the field of forest tree breeding the measurements would be performed from increment core …
A candidate method based on UV-fluorescence of stilbenes is under development for fast measurement of stilbene concentration on solid heartwood of Scots pine (Pinus sylvestris L.). Development is focused on …
Scots pine (Pinus sylvestris L.) heartwood is rich of stilbenes, which are known to have antimicrobial and antifungal effects. Wide natural among-tree variation has been reported in heartwood stilbene content, …
There is wide natural variation among individual Scots pine (Pinus sylvestris L.) trunks in decay resistance-giving extractive, such as stilbenes, contents. Effective exploitation and research of pine heartwood requires fast …
