Climatic parameters are the main environmental factors affecting tree growth. The main aim of
the presented study was to determine whether different oak species growing under contrasting environmental
conditions show different sensitivity to climatic parameters. Four oak stands with Quercus robur,
Quercus petraea, Quercus polycarpa and Quercus dalechampii growing in the same area were evaluated. Standard
dendrochronological methods were used for sample preparation, ring width measurements, cross-dating,
chronology development, and the assessment of growth-climate response patterns. Although the species
grew under different environmental conditions, their local tree-ring chronologies are highly correlated. The
radial growth responses to climatic parameters differ slightly, but the response depends more on local site
conditions than on the oak species. At the same time, the strongest correlations between radial growth and
climatic parameters were identical among species and sites. The amount of water available in the soil was
the main climate-dependent factor limiting radial growth. Approximately since the 1990s, the distribution
of rainfalls within the growing season has changed at the expense of spring precipitation. The significance
of relative soil moisture content during spring for oak growth increased and the significance of summer
values decreased.
