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, which is also highly inherited. Cost-effective exploitation of Scots pine heartwood requires fast and reliable techniques to sort the raw-material according to its’ extractive content. Also breeding for chemical quality of Scots pine heartwood benefits from new technologies. In this study, two heartwood increment core samples have been drilled from each of 212 standing seed orchard grafts. The outer part of the heartwood of one of the cores has been ground for chemical analysis performed with a gas chromatograph. The UV fluorescence measurement has been performed on the outer part of the heartwood of the freshly split surface of the other core. The results of the measurements will be presented.
