Genetska variabilnost bukve (Fagus sylvatica L.) v Sloveniji
Raziskava obravnava genetsko variabilnost, genetsko raznolikost in genetsko diferenciacijo bukve (Fagus sylvatica L.) v Sloveniji. S pomočjo izoencimske analize smo pregledali 13 avtohtonih bukovih populacij. Polimorfizem smo odkrili na 11 od 12 analiziranih izoencimskih lokusih, 9 lokusov je polimorfnih v vseh populacijah. Opazen je rahel trend naraščanja genetske variabilnosti v smeri od severa proti jugu, medtem ko povprečna ugotovljena heterozigotnost Ho od severa proti jugu upada. Genetska diferenciranost je razmeroma majhna, med populacijami pa nismo odkrili diferenciranosti, ki bi ji lahko pripisali jasno geografsko pogojenost.
The study investigates the genetic variability, genetic diversity and genetic differentiation of the beech (Fagus sylvatica L.) in Slovenia. On the basis ofisozyme analysis, 13 indigenous beech populations were examined. Polymorphism was revealed in 11 isozyme loci, 9 loci show polymorphism in all treated populations. The trend of slight north-south increase of genetic variability is present, while mean observed heterozygosity Ho decreases in thenorth-south direction. Genetic differentiation is relatively weak and we revealed no geographically conditioned differentiation among the populations.
