Abstract (Swedish)
Aims: To compare growth variability of Scots pine (Pinus sylvestris L.) on different soil types, and to assess the potential of peat-soil pines for climatological and hydrological studies.
Methods: We used extensive dendrochronological anal- yses to investigate temporal and spatial responses of pines growing on peat soils and mineral soils in three regions of Lithuania.
Results: Significant correlations were observed be- tween tree populations growing on similar soil types in different geographical regions, whereas synchronicity was absent between neighbouring stands growing on different soil types. At mineral soils, tree growth was significantly correlated with winter and early summer temperatures, whereas a more complex response... (More)
