The taxonomic status of beech from the Balkan Peninsula is not yet clearly
defined. There is no agreement among different authors about the
morphological characteristics discriminating between the Balkan and European
and/or Eastern beech. For most characteristics, the mean values are different
but the ranges of variation overlap considerably. Provenance trial of beech
established in Serbia, at the locality Debeli Lug, has provided an
opportunity for research of interprovenance variability at the level of leaf
morphometric characteristics in juvenile development stage. Research included
10 provenances originating from the Western Balkans (Serbian provenance 36
and 38; Croatian provenance 24 and 25; Bosnian provenance 30 and 32) and from
Central Europe (German provenance 47 and 49; Austrian provenance 56 and
Hungarian provenance 42), where following morphometric characteristics were
analyzed: leaf length (Ll), leaf width (Lw), petiole lenght (Pl), leaf base
width on 1 cm (Blw), number of veins - left (Vl), number of veins - right
(Vr), distance between 3rd and 4th vein - left (Dv 3-4). The results of this
research show existence of clear differentiation among provenances from the
Western Balkan and from Central Europe, from the point of leaf dimensions,
number of veins and leaf base width.
