Franco) in smreke (Picea abies (L.) Karst.) na podnebje na produktivnem rastišču Pečovnika pri Celju| Radial growth and response of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) and Norway spruce (Picea abies (L.) Karst.) to climate on productive site of Pečovnik near Celje|We analysed the growth of Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) and Norway spruce (Picea abies (L.) Karst.) at a productive site in Pečovnik near Celje. The analysed Douglas firs were slightly younger than spruces (67 vs 71 years) and grew slightly better (4.57 mm vs 3.26 mm per year). The climatic response of Douglas fir on the productive site was very pronounced. The radial increment was statistically significantly influenced by above-average temperatures in February and March and above-average precipitation in July. Compared to spruce, the climatic response of Douglas-fir is temporally stable and significantly more pronounced. Analysis of pointer years has shown that negative pointer years in Douglas-fir are always associated with very cold weather in February and March and positive years with above-average temperatures in the same two months. Summer precipitation has played a more important role in Douglas-fir only in the last three decades, but not before that. This suggests a potential lack of water in an otherwise very productive site that could lead to drought stress and poorer growth of Douglas-fir in the long term, given climate change trendsAnalizirali smo rast duglazije (Pseudotsuga menziesii (Mirb.) Franco) in smreke (Picea abies (L.) Karst.) na produktivnem rastišču na Pečovniku pri Celju. Analizirane duglazije so bile nekoliko mlajše od smrek (67 proti 71 let) in so nekoliko bolje priraščale (4,57 mm proti 3,26 mm na leto). Podnebni odziv duglazije na produktivnem rastišču je bil zelo izrazit. Na debelinski prirastek so statistično značilno vplivale nadpovprečne temperature v februarju in marcu, ter nadpovprečne padavine v juliju. V primerjavi s smreko je podnebni odziv duglazije časovno stabilen in bistveno izrazitejši. Analiza značilnih let je pokazala, da so negativna značilna leta pri duglaziji vedno povezana z zelo hladnim vremenom v februarju in marcu, pozitivna pa z nadpovprečnimi temperaturami v istih dveh mesecih. Poletne padavine imajo pomembnejšo vlogo pri duglaziji le v zadnjih treh desetletjih, pred tem pa ne. To nakazuje, da na sicer zelo produktivnem rastišču nastaja potencialno pomanjkanje vode, kar lahko na dolgi rok, ob trendih podnebnih sprememb, vodi v sušni stres in slabšo rast duglazijeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZveza gozdarskih društev Slovenije
