Varijabilnost morfoloških svojstava listova europske crne topole i hibridnih crnih topola u klonskom arhivu u Žepču
Mirzeta Memišević Hodžić, Dalibor Ballian, 2023, izvirni znanstveni članek

Povzetek: Black poplar (Populus nigra L.) is one of the most important European tree species, inhabiting alluvial habitats along the banks of large rivers. Today, it is one of the most endangered species of forest trees due to habitat devastation, regulation of river flows, excessive exploitation, and the introduction of non-native tree species with which it hybridized. This study aims to determine the variability of morphological properties of black poplar leaves n Bosnia and Herzegovina, within and among populations, and among river basins. Material from the clonal archive of black poplars was researched. The archive was founded in 2005 in Žepče. It contains clones from 161 trees of indigenous black poplars from 26 populations throughout Bosnia and Herzegovina (from the basins of 6 rivers) and 15 hybrid poplar species (table 1 and table 2). Ten leaves were collected from each clone by taking the fifth leaf from the top of the main shoot. Five leaves from each clone were measured. The measurement was performed with a digital movable scale with an accuracy of 0.1 mm and a protractor. The following traits were measured: leaf blade length, leaf blade width, petiole length, total leaf length, the angle between the first lateral nerve and central nerve, and distance from the leaf base to the widest part of the leaf. The number of teeth on one cm above the widest part of the leaf was counted. Data were processed using SPSS 26.0 and EXCEL by populations and river basins. Analysis of variance revealed that there are statistically significant differences among the studied populations (table 4), as well as among river basins (table 7), for all investigated traits. The petiole length trait showed the highest variability, and the lowest variability had the insertion angle of the first lateral and central nerve (table 3). The clones of population of hairy black poplars Čapljina had the lowest values of leaf traits and differed significantly in all measured properties from the others. The most common number of teeth per 1 cm of leaf edge for all populations was four teeth (figure 2), which appeared on 38.3% of leaves. This research gives us a small insight into the morphological characteristics of black poplars in the clone archive Žepče and can be the basis for further researches of the traits of black poplars needed for a successful continuation of work on breeding this species

Morphological traits of Scots pine (Pinus sylvestris L.) in international provenance tests in Bosnia and Herzegovina
Mirzeta Memišević Hodžić, Semir Bejtić, Selma Vejzagić, Dalibor Ballian, 2020, izvirni znanstveni članek

Povzetek: Scots pine (Pinus sylvestris L.) is one of the most important tree species in European forests. This study aims to determine whether there is inter-provenance variability in researched morphological traits in two international provenance tests of Scots pine in Bosnia and Herzegovina. We measured height, root collar diameter, and latest shoot length and counted branches on the latest branch whorl of Scots pine plants in two provenance tests. The provenance tests are located in Kupres and Žepče, in different climatic, edaphic, and orographic conditions. Kupres and Žepče contain 15 and 14 provenances, respectively, eleven of which are mutual to both sites. Descriptive statistics and analysis of variance showed differences among provenances in all investigated morphological traits. These differences were attributable to provenance test, provenance, and interaction between provenance test and provenance. The average values were higher in Žepče for all provenances and all studied traits. The Austria A1, Austria A2, Austria A3, and Poland P1 provenances showed the best growth in both tests, while the Italy I1 provenance showed good growth in Žepče but not in Kupres.
