Sažetak
International beech provenance trial Medvednica is located on the homonymous mountain near Zagreb, Croatia. Trial was established in 2007 with 21 provenances from 9 European countries. The trial was laid out according to RCBD experimental design, with each provenance represented by 50 plants in three replications (blocks), planted in rectangular plots with 2.0 × 1.0 m spacing (Ivanković et al. 2011). 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. Analyses of variance (ANOVA) were performed using the MIXED procedure in SAS software. Results showed significant differentiation among provenances in flushing phenology and height. Between provenance differences were further tested with post-hoc Tukey–Kramer’s test which showed higher level of differentiation for flushing phenology and lower level of differentiation for height growth. Multivariate regression tree 45 (MRT) analysis was used to determine the pattern of genetic differentiation (Hamann et al. 2011). MRT analysis of heights and survival rates separated provenances with respect to the latitude and longitude. Provenances from eastern habitats had lower mean heights and mean survival rate than those originating from the western habitats. MRT analysis of flushing phenology separated provenances with respect to the continentality variable and humidity. Provenances originating from relatively more humid habitats flushed later. With the increase of continentality and humidity, provenances showed a trend of earlier flushing. Results of this study suggest genetic differences among provenances, driven by natural selection in original sites. Further research in this provenance trial will provide better insight about adaptability of the provenances in a given environmental conditions. According to Gömöry (2009), 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.
