Variability of generative offspring of field maple (Acer campestre L.) in nursery testing
Dalibor Ballian, Mirzeta Memišević Hodžić, Miroslav Murlin, Stjepan Kvesić, 2022, original scientific article

Abstract: Field maple (Acer campestre L.) is naturally distributed in most of Europe, with the exception of its northern parts. Field maple can serve as a valuable model for researching the sensitivity of its populations to habitat fragmentation, considering the lack of silvicultural treatments in its stands. The research aims to determine the interpopulation and intrapopulation variability of field maple populations from Bosnia and Herzegovina in the nursery test.The authors researched measured root collar diameter, height, observed forkness and calculated slenderness coefficient of the one-year-old generative material from 18 Bosnian-Herzegovinian populations of field maple, produced in the nursery of Žepče. The descriptive statistics and variance analysis was performed.All analyzed traits showed a high degree of intrapopulation as well as interpopulation variability, as confirmed by the analysis of variance. The highest average height was found in the provenance Bosanski Brod (46.08 cm) and the smallest in Bosanska Dubica (19.11 cm). Kreševo provenance had the highest average root neck dia-meter (8.27 mm) and Bosanska Dubica (5.24 mm) the lowest. A very low percentage of forkness (6.86%) was determined, and the values of the slenderness coefficient were acceptable for all provenances.The results indicate the need for further systematic research on this ecologically valuable species.

Morphologic variability of the Acer campestre L. populations in Bosnia and Herzegovina
Stjepan Kvesić, Mirzeta Memišević Hodžić, Matjaž Čater, Dalibor Ballian, 2021, original scientific article

Abstract: Morphologic variability from 25 populations of Acer campestre L. in Bosnia and Herzegovina was analyzed. Morphometric structure of variability and between-population variability was performed based on 10 fruit-parameter characteristics and 19 leaf-parameter characteristics using multivariate statistical analysis. Results confirmed the separation of three submediterranean populations as a group in relation to other tested populations, from which the Banja Luka population is different. Measured leaf parameters were confirmed as a predominant carrier of the morphologic separation between populations. In other Acer species populations within A. monspessulanum and A. intermedium species are separated mainly by fruit and much less by leaf parameters. The southernmost submediterranean populations from Trebinje, Ljubuški, and Mostar regions have smaller leaf areas, which consequently places them within the same morphologic group; their variability is in tight connection with eco-geo-graphical factors, where the ecological distance is a much better predictor of morphological variability compared to geographical distance. The air temperature had the biggest influence on morphological variability regarding the highest in-between correlation. Achieved results may serve for the continuation of the research in other areas of Acer campestre to determine the interactive effect of ecological, geographical, climatic, and migrational factors on their morphologic population plasticity.
