Growth Tendency of Quercus robur L. Provenances in Bosnia and Herzegovina Provenance Test with Relation to Fixation Index
Öz
Aim
of study:
Specific genetic structure of the remaining populations of pedunculate oak (Quercus robur L.) in Bosnia and Herzegovina makes them significant for the
preservation of the diversity of this species in Bosnia and Herzegovina and
Europe. For this reason, we established provenance test in 2009. The aim of the
study is to determine the correlation between provenance growth and fixation
index. The ultimate goal is the reintroduction of the species in suitable
areas.
Material
and method: The research included measuring the height and the
root collar diameter of four-, six- and eight-year-old plants in the provenance
test and molecular analyses using isoenzymes.
Main
results:
Variance analysis showed statistically significant differences between
populations in all tested characteristics, which was confirmed by the Duncan
test. Provenances of Miljevina Foča, Stojčevac, and Visoko Muhašinovići are at
the bottom of the list with the lowest growth of four-, six-, and
eight-year-old plants. Provenances of Drvar, Mutnica Cazin, Kaćuni, and Jelah
showed the best growth.
Highlights: Eight provenances showed positive fixation index values, particularly Miljevina Foča, Bosanska Dubica, and Drvar. Positive fixation index value of Miljevina provenance matches its low growth, while this is not the case in Drvar and Bosanska Dubica provenances.
