Summary: | This paper presents the results of a study dealing with leaf morphological
variability of Quercus robur L. 148 trees were sampled from 5 population
across Serbia and 17 morphological traits were assessed. Interpopulation
variability was confirmed by the results of the analysis of variance (ANOVA).
A statistically significant (p <0.05) effect of population was obtained for
most of the studied morphological characters. Intrapopulation variability was
confirmed by statistically significant tree effects for all of the studied
leaf characters (all p < 0.05). The results of the multivariate analysis of
variance (MANOVA) confirmed a significant population and tree share in the
total phenotypic variability (all p <0.05). By applying the canonical
discriminant analysis (CDA), the first discriminant function accounted for
63% of the variability between populations and the second accounted for 20%
of the population variability. The leaf area (AREA), specific leaf area (SLA)
and surface area to perimeter ratio (ARPE) had the greatest effect on
population differentiation (CDA). It is assumed that different environmental
conditions affect population differentiation and that high intrapopulation
variability is due to intraspecific variability. |
