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 to replace the stilbene concentration measurements achieved by gas chromatography mass spectrometry (GC-MS) having multiple pretreatment steps. Measurements of stilbene concentrations of Scots pine are important due to their effect on decay resistance. The cost-effective and reliable methods for phenotyping and measuring widely varying and strongly inherited stilbene concentrations are increasingly needed in Scots pine improvement due to soon available tools of genomic selection also in this field. The features of the measurements of stilbene concentrations on solid heartwood samples by using the studied device are discussed.
