Abstract:
The aim of this paper was to assess the inter-provenance variability of beech at the level of morphological characteristics of leaves. The research was conducted in the provenance trial of beech, established 2007 in Serbia at the locality „Debeli Lug“, and included 17 provenances: five Serbian, two Croatian, three Bosnian, three German, one Austrian, one Hungarian and two Romanian provenances. Ten 12-and-13-year-old beech trees were randomly selected from each provenance and 30 leaves were collected from each tree. Herbaria material was used for measuring of the six morphological parameters: leaf length, leaf width, petiole length, number of veins on the right side from the midrib, number of veins on the left side from the midrib and distance between the 3rd and 4th vein. The data were processed by the „STATGRAPHICS Centurion XVI“. Descriptive statistics, analysis of variance (ANOVA), LSD test (Fisher’s least significant difference test) and cluster analysis were done. Based on the obtained results, it can be stated that there were statistically significant differences between mean values of all measured characteristics of leaves. The highest average values for four out of six characteristics of leaves were recorded in Bosnian provenance (number 30); while the lowest average values (or among the lowest) were recorded in German provenances (number 47 and 49). The closest linkage was registered between two Croatian provenances (number 24 and 25); while the German provenance number 48 did not form close linkage with any other provenance.
