Sažetak
International beech provenance trial "Medvednica" was established 10 years ago on homonymous mountain near Zagreb, Croatia. Trial involve 21 provenance from 9 European countries which are arranged in a randomized complete block design with each provenance represented by 50 plants in three replications (blocks), planted in rectangular plots with 2.0 × 1.0 m spacing. The aim of this study was to determine the amount and pattern of adaptive genetic variability among populations for height growth, survival and flushing phenology. The data were obtained 2009 and 2016 for flushing phenology and 2010 and 2015 for height growth. Analyses of variance (ANOVA) were performed using the MIXED procedure in SAS software to determinate differentiation among provenances in flushing phenology and height. Multivariate regression tree (MRT) analysis was used to determine the pattern of genetic differentiation. Results of this study suggest genetic differences among provenances, driven by natural selection in original sites. Better insight about adaptability of the provenances in a given environmental conditions will be provided with further research in this provenance trial. Researches like this are important for identification of provenances which are characterized by good growth and adaptability, in order to use it as a seed source for future reforestations.
