The research was conducted on a provenance test of beech established in the
Educational-research centre „Majdanpečka domena” - Faculty of Forestry,
University of Belgrade. This paper presents the results of an analysis of the
morphometric characteristics of leaves, at the level of 10 provenances in the
juvenile developmental stage, originating from South-Eastern Europe. Herbaria
material was used to measure the following parameters: leaf length, leaf
width, petiole length, leaf base width at 1 cm (from petiole base), the
number of veins -on the left, the number of veins - on the right, and
distance between the 3rd and 4th vein - on the left. Based on research
results, it can be concluded that the obtained differences between the mean
values of all measured foliar characteristics of the analyzed provenances are
statistically significant, and that there is significant correlation between
the length and width of leaves and the Ellenberg’s quotient (EQ). The
relationship between the adaptive traits of beech from different provenances
and ecological parameters of their seed source stands indicates genetic
differentiation of beech, as a consequence of the population adaptation to
local environmental conditions. Therefore, in the future, ecological criteria
must be a priority in the selection of seed sources and planting materials,
with special consideration of the global climate change.
