Abstract

U radu je istražena genetička i morfološka varijabilnost šest populacija običnog bora na području Hrvatske te Bosne i Hercegovine. Raznolikost populacija analizirana je na temelju devet mjerenih morfoloških značajki iglica i češera te sedam mikrosatelitskih biljega. Vrijednosti efektivnog broja alela kretale su se od 2,307 (Saborsko) do 2,908 (Plitvička jezera), a vrijednosti alelnog bogatstva od 4,056 (Saborsko) do 4,919 (Plitvička jezera). Istraživanjem nije zabilježena statistički značajna vjerojatnost da istraživane populacije nisu u Hardy-Weinbergovoj ravnoteži, kao niti da su prošle kroz genetički usko grlo. Zabilježena je visoka varijabilnost istraživanih morfoloških značajki, te se koeficijent varijabilnosti na razini svih populacija kretao od 13,80 % za svojstvo širina štitića do 33,04 % za svojstvo debljina štitića. Unutarpopulacijska varijabilnost bila je veća od međupopulacijske varijabilnosti u obje analize, genetičkoj i morfološkoj. Za većinu mjerenih morfoloških značajki utvrđene su statistički značajne razlike između istraživanih populacija, dok na genetičkoj razini te razlike nisu potvrđene. Ovo istraživanje predstavlja inicijalnu platformu za daljnja istraživanja te formiranje smjernica za kvalitetno očuvanje genskih resursa i gospodarenje šumama običnoga bora na području Hrvatske i Bosne i Hercegovine.

Abstract (english)

This study investigated the genetic and morphological variability of sixpopulations of Scots pine in Croatia and Bosnia and Herzegovina. Population diversity was analyzed based on nine measured morphological traits of needles and cones and seven microsatellite markers. The values of the effective number of alleles ranged from 2.307 (Saborsko) to 2.908 (Plitvička jezera), and the allelic richness values from 4.056 (Saborsko) to 4.919 (Plitvička jezera). The research did not record a statistically significant probability that the studied populations were not in the Hardy-Weinberg equilibrium, nor that they passed through a genetic bottleneck. A high variability of the investigated morphological traits was recorded, and the coefficient of variability at all populations level ranged from 13.80% for the trait of cone scale apophysis width to 33.04% for the cone scale apophysis thickness. Intrapopulation variability was greater than interpopulation variability in both genetic and morphological analyses. Statistically significant differences between the studied populations were found for most of the measured morphological traits, while these differences were not confirmed at the genetic level. This research represents an initial platform for further research and the formation of guidelines for conservation of genetic resources and management of Scots pine forests in Croatia and Bosnia and Herzegovina.
