Povzetek

Opravili smo dendrokronološke in dendroklimatološke raziskave lesa hrasta (Quercus sp.) z območja Dolenjske. S pomočjo programa TSAP/x in ARSTAN smo sestavili različne tipe kronologij širin branik in širin kasnega lesa. S pomočjo programa DENDROCLIM 2002 smo proučili zvezo med širinami branik in kasnega lesa ter klimo (skupne mesečne padavine in povprečne mesečne temperature). Lokalna kronologija širin branik in kasnega lesa za hrast z Dolenjske je dolga 191 let (1812 - 2003). Zaporedij širin ranega lesa ni bilo mogoče sinhronizirati in sestaviti kronologije. Dendroklimatološka analiza je pokazala, da na širino branik in na širino kasnega lesa odločilno vplivajo junijske padavine (pozitiven vpliv) in junijske temperature (negativen vpliv). Korelacijski koeficienti vpliva junijskih temperatur in junijskih padavin na širine branik in širine kasnega lesa so stabilni v času za obdobje zadnjih 100 let, za katerega imamo na voljo podatke o klimi.

Sekundarni naslov:	Local chronology of oak (Quercus sp.) from the Dolenjska region, Slovenia
Sekundarni povzetek:	Oak wood (Quercus sp.) from trees growing in the Dolenjska region of Slovenia was dendrochronologically and dendroclimatologically analysed. Using TSAP/x and ARSTAN computer programmes different types of tree-ring width and late-wood width chronologies were composed. Further DENDROCLIM 2002 computer programme was used to calculate the relation between tree-ring widths and late-wood widths to climate (sum of monthly precipitation and average monthly temperatures). A 191 year-long local chronology, spanning the period of 1812 -2003, has been constructed. The sequences of early-wood widths could not be synchronized or assembled into a chronology. The dendroclimatological analysis showed that growth-ring widths and late-wood widths were mainly affected by June precipitation (positive effect) and June temperatures (negative effect). Correlation coefficients showing the relation between tree-ring or late-wood widths to June temperatures and precipitation proved to be stable in time for the period of last 100 years, for which the instrumental climatological data are available.
