Analysing the adaptability of European beech provenances in Croatia

A provenance experiment of European beech (Fagus sylvatica L.) was established in Croatia in 1998. Six provenances were selected. Flushing as a property of physiological character was monitored in 7 phenophases, which were recorded on 7 dates during the year 2001. Differences in entering phenophase 3 (indicating the very beginning of flushing, importance in determining resistance to late frosts), were analysed using product limit estimator. A log rank test was conducted to determine whether there were any statistically significant differences in entering phenophase 3 among the provenances. For multiple comparisons post hoc Hochberg’ s (step-up) algorithm has been used. Flushing similarity was analysed with hierarchical and non-hierarchical cluster analysis. The provenances were ranked with AHP in order to select the most adaptable ones using the following criteria: survival, entering phenophase 3, mean height.
