Sažetak
We analysed sapwood characteristics in 344 pedunculate oak (Quercus robur L.) samples from the south-western part of the Pannonian Basin. The samples came from 13 sites, located in Slovenia, Croatia and Serbia. The trees had an average of 13.3 sapwood rings, with a minimum of 5 and maximum of 32. Fifteen log-log linear regression models were employed to assess the statistical relationship between sapwood and heartwood variables. The number of sapwood rings (N-SW), which is usually needed in dendroarchaeological dating, is significantly related to the number of heartwood rings (N-HW), heartwood width (W-HW) and heartwood growth rate (G(HW)). Older and more slowly growing trees had a higher average number of sapwood rings. Using N-HW and W-HW, we employed an additional multiple regression model and calculated coefficients for N-SW predictions for real-world dendroarchaeological dating from the south-western part of the Pannonian Basin.
