Abstract
DENDROCHRONOLOGICAL INVESTIGATIONS IN SLOVENIA. We present the results of the third year of investigations. The objectives were to obtain new knowledge on factors affecting tree growth and wood formation, and to construct Slovenian reference chronologies for dating. Tree-ring chronologies of larch (Larix decidua) and fir (Abies alba) showed good cross-matching within Slovenia and with those from other European regions. We constructed long regional chronologies for dating both species and continue to improve and prolong them. Dendroclimatological investigations exemplified by the fir from Slovenia and the red spruce (Picea rubens) from the USA indicate the lack of temporal stability in dendroclimatology, therefore caution is needed with dendroclimatic reconstruction. Dendrochronological methods were used to evaluate growth of Norway spruce (Picea abies) from climatically specific chill sites in the Karst valleys, and variability of population structure of supposedly native Norway spruce from Pokljuka. Wood anatomical features like resin canals in black pine (Pinus nigra) and changes due to fraying damage in young ash (Fraxinus excelsior) were studied as possible variables in dendrochronology. The ongoing research in oak (Quercus petraea and Q. robur) showed that both species from the same site can be cross-dated as well as they can be cross-dated with ash. In co-operation with the Restoration Centre and the Institute of Archaeology, ZRC SAZU we continued investigations of historic and archaeological timbers. Beside modern and historic ones we constructed 12 chronologies from 6 pile dwellings in the Ljubljana Moor. This chronologies are not dated yet, but first radiocarbon dates of the Heidelberg Academy of Sciences give a good orientation for their future dating. We report on co-operation with other institutions from Slovenia, European countries, and USA.
