Long-Term Climate Sensitivity of Resin-Tapped and Non-Resin-Tapped Scots Pine Trees Based on Tree Ring Width and Blue Intensity

The resin tapping of pine trees in Poland ended the early 1990s. However, we can still find individual trees, and sometimes larger groups that were tapped. This study focused on effect mechanical wounding during growth climatic sensitivity trees. concerned a 160-year-old stand northwestern which was last performed 1970s. All had remained standing because their high quality, destined them for seed collection. included both resin-tapped (RT) non-RT (NRT) Our based dendrochronological analysis two signals—annual tree ring widths (TRWs) delta blue intensity (DBI). We observed significant increase annual TRW after ceased, alongside decrease DBI. temporal stability response examined using daily correlations from 1921 to 2021. It found RT NRT pines similar. There differences only some years, most while occurring, then approximately 20 years ceased. these small mainly related strength correlation. also discovered obtain different types information TRWs
