551. Phytochemicals and their correlation with molecular data in micromeria and Clinopodium (Lamiaceae) taxaDario Kremer, Valerija Dunkić, Ivan Radosavljević, Faruk Bogunić, Daniella Ivanova, Dalibor Ballian, Danijela Stešević, Vlado Matevski, Vladimir Ranđelović, Eleni Eleftheriadou, Zlatko Šatović, Zlatko Liber, 2022, original scientific article Abstract: A study of the phytochemical and molecular characteristics of ten Micromeria and six Clinopodium taxa (family Lamiaceae) distributed in the Balkan Peninsula was carried out. The phytochemicals detected in essential oils by gas chromatography, mass spectrometry, and molecular data amplified fragment length polymorphism were used to study the taxonomic relationships among the taxa and the correlations between phytochemical and molecular data. STRUCTURE analysis revealed three genetic groups, while Bayesian Analysis of Population Structure grouped the studied taxa into 11 clusters nested in the groups obtained by STRUCTURE. Principal components analysis performed with the 21 most represented compounds in the essential oils yielded results that were partly consistent with those obtained by STRUCTURE and neighbour-joining analyses. However, their geographic distributions did not support the genetic grouping of the studied taxa and populations. The Mantel test showed a significant correlation between the phytochemical and genetic data (r = 0.421, p < 0.001). Genetic distance explained 17.8% of the phytochemical distance between populations. The current taxonomic position of several of the studied taxa is yet to be satisfactorily resolved, and further studies are needed. Such future research should include nuclear and plastid DNA sequences from a larger sample of populations and individuals.

552. Trends in the Phenological Pattern of Hybrid Plane Trees (Platanus × acerifolia (Ait) (Wild)) in Sarajevo Ecological ConditionsMirzeta Memišević Hodžić, Dalibor Ballian, 2022, original scientific article Abstract: Phenological research of plant species is of great importance in the context of adaptation to climate change and changing environmental factors, especially in dynamic urban environments, such as the area of Sarajevo. This research aims to determine trends in the phenological pattern of hybrid plane trees in the area of Sarajevo so that recommendations can be made for the use of plane trees in greening urban and suburban areas since they largely depend on microclimatic conditions. In this paper, the authors researched the variability of leafing phenology of maple (Platanus × acerifolia (Ait) (Wild)) at six different localities in the area of Sarajevo. Observations were made in the spring of 2009, 2014, 2016, and 2020. Six phenological phases in the spring aspect of leaf development were monitored (0 - dormant buds, 1 - beginning of bud opening, 2 - open buds, 3 - leaf opening, 4 - young leaves, 5 - fully developed leaves). The results showed differences in the beginning and end of phenological phases by years and localities. Analysis of variance showed statistically significant differences in the duration of leaf development phases caused by the year of observation, locality, and the interaction of locality and year, which indicates the influence of seasonal climatic elements and micro-location conditions, as well as their interaction on the occurrence of phenophases. The results of this research can be used to recommend the use of plane trees in selected locations, with the selection of appropriate provenances and respect for phenological characteristics. Research needs to be continued and extended to leaf rejection research, which is particularly significant given the frequent heavy snowfall during the winter months in the investigated area.

553. Interakcija između efekata genetskestrukture i stanišnih uslova narast zelene duglazije u testovimaprovenijencija u Bosni i HercegoviniMirzeta Memišević Hodžić, Dalibor Ballian, Emina Šehović, 2020, original scientific article Abstract: Douglas fir (Pseudotsuga menziesii (Mirbel) Franco) is the most important and most productive species in Eu-rope, outside its natural range. This study aimed to examine the presence of interaction between the effects of the genetic structure of provenances from the United States and Canada and three localities of provenan-ce tests in Bosnia and Herzegovina.For this research, we measured diameters at breast height of all trees, and heights of 10 trees per provenance in three tests of Douglas fir at the age of plants 32 years. Four provenances are represented in all three tests and additional two provenances in two tests. We examined the variance between provenances and habitats using multivariate analysis, for four provenances in all three habitats, and six provenances in two habitats (Bo-sanska Gradiška and Zavidovići).Multivariate analysis of variance for four provenances at all three localities showed that there were no stati-stically significant differences in diameters at breast height and heights caused by the interaction of provenan-ces x localities. Multivariate analysis for six joint provenances at Bosanska Gradiška and Zavidovići tests showed that there were no statistically significant differences for diameter at breast height caused by interac-tion locality x provenance, and there were statistically significant differences caused by interactions of locality x provenances for height.The obtained results can be used for the introduction of Douglas fir on predefined habitats that correspond to the conditions of the experimental plots, as well as for the selection of the best provenances for raising clone plantations or seed plantations

555. Continental-wide population genetics and post-Pleistocene range expansion in field maple (Acer campestre L.), a subdominant temperate broadleaved tree speciesEric Wahlsteen, Evangelia V. Avramidou, Gregor Božič, Rida Mohammed Mediouni, Bernhard Schuldt, Halina Sobolewska, 2023, original scientific article Abstract: Acer campestre L. is a rarely silviculturally managed and poorly investigated European tree species which forms seminatural populations and can thus be considered as a model tree for studying post glacial colonisation and phylogeography. Herein, we studied the genetic structure of Acer campestre L. in order to investigate population and genetic diversity clines over the distribution range and for synthesizing the results into a post-Pleistocene range expansion hypothesis. We characterised the genetic diversity and population structure of 61 Acer campestre populations using 12 microsatellite markers. The three detected gene pools are structured geographically creating a longitudinal pattern corresponding with their proposed refugial origin. The results indicated a longitudinal population cline with three strong but highly admixed gene pools. Based on the possible signal from the structure results, a number of phylogeographic dispersal hypotheses were tested using approximate Bayesian computation, and this analysis supported the three refugia scenario with a simultaneous divergence prior to the last glacial maximum. Acer campestre shows a typical decrease in population diversity with northern and western distribution and signatures of surfng alleles in the western expansion axis in 2% of the included alleles. Acer campestre exhibits a high degree of admixture among populations and typical signatures of isolation by distance with no naturally delimited subpopulations. The population structure is rather impacted by geographically, than climatologically means with surfng alleles and alleles strongly limited to geographical areas. Our data also suggest that the population structure still today harbours signatures of post glacial migrations from Mediterranean as well as northern glacial refugia.
