Abstract:Z dendrokronološkimi metodami smo analizirali debelinsko priraščanje smreke na osmih lokacijah v Sloveniji. Med njimi je bilo pet naravnih smrekovih združb, v druge je bila smreka umetno vnesena v preteklosti, oziroma je bil povečan njen naravni delež. Na vsaki ploskvi smo s prirastoslovnim svedrom odvzeli izvrtke najmanj 20 dreves. V dendrokronološkem laboratoriju smo jih posušili in zbrusili do visokega sijaja, nato pa skenirali s pomočjo sistema ATRICS ter izmerili širine branik v programih CooRecorder in CDendro. Ugotovili smo, da med naravnimi in antropogenimi rastišči ni značilnih razlik v debelinskem priraščanju. Na lokacijah Sorško polje, Ravnik in Mašun smo opazili spremembe v debelinskem priraščanju, ki kažejo, da se vpliv temperature zraka (toplejša poletja) in padavin (pogostejši pojav suše) na rast povečuje. Analiza značilnih let je pokazala, da so le-ta v zadnjih 30 letih pogostejša in da se pojavljajo na več lokacijah hkrati, predvsem pa se je povečalo število negativnih značilnih let, t.j. nadpovprečno toplih in suhih let.

Title:Dendrochronologycal analysis of the radial growth of Norway spruce (Picea abies (L.) Karst.) In its natural and secondary stands in Slovenia
Abstract:A dendrochronological analysis of the spruce's radial increment at eight different plots was conducted throughout Slovenia. The plots selected were diverse: five of them were natural spruce stands; in others, the spruce was introduced anthropogenically in the past for economic reasons, or its natural share in stands was increased. We took samples of at least 20 trees per plot and examined them in the dendrochronological laboratory using Advanced Tree-Ring Image Capturing System (ATRICS) and specialized dendrochronological software. We compared the growth in natural spruce stands with the secondary (anthropogenic) ones and found no statistical differences in growth patterns between these two groups. However, we found some evidence for climate change effect on radial increment at locations Sorško polje, Ravnik and Mašun, which indicates that air temperature and precipitation now have stronger effect on spruce growth than in the past. Analysis of pointer years suggests that extreme events (exceptionally warm and dry years) are more common and widespread in the last 30 years.
