Variability of survival and height growth in pedunculate oak provenance trials – “Jastrebarski lugovi” and “Koška”, Croatia
Pedunculate oak (Quercus robur L.), which accounts for one tenth of all the forest in Croatia, is one of the most valuable forest tree species. Provenance trials, where populations of different geographical origin are tested in a common environment (common garden test), are a tool suited to allow the study of intraspecific adaptive genetic variation. The aim of the research in provenance trials is to identify provenances that are characterized by good growth and adaptability, to be used as a source of seed for future afforestation. In Croatia, two trials (Jastrebarski lugovi and Koška) were established in 2008 and 2010 for research withinspecies genetic variability of pedunculated oak populations originating from Austria and Croatia. Genetic field trials involved 22 provenances (17 Croatian and 5 Austrian) planted over a total area of 3.75 ha in 2.5 by 2.0 m spacing. Trials were established according to a randomized complete block experimental design with three replications (blocks). In total, 6 600 saplings were planted. Research of adaptive genetic variability of oak populations was conducted by analysis of height growth and survival. Survival for first analyzed year at trial Jastrebarski lugovi was extremely good (98.73%), but after it visibly decreased. The total mean height of all plants in the trial in 2016 was 441.51 cm. The mean survival of studied plants at trial Koška in first analyzed year was 84.61%. In 2016, survival was 68.3% and average height of plants was 255.79 cm.
