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 based on UV light excited fluorescence of phenolic stilbenes, which are the important resistance-related compounds in Scots pine heartwood. The project contributes to new and improved products as well as to material-efficient production techniques, technologies and services. New measurement technology would enable the tree breeders to produce improved forest regeneration material, which would produce decay resistant heartwood when aging. Graded extractive-rich heartwood timber could be used in certain decay-resistance requiring applications or it could be used as raw-material for chemical industry.
