Biological diversity of dogwood (Cornus mas L.) population in the Stara Planina region

Abstract

In the Stara Planina population, dogwood (Cornus mas L.), is one of the most spreaded fruit species, according to the method developed by Braun-Blanquet, 1964 - it spreads over 80-100% of areas, and it covers 25-50% of surface. In the Stara Planina region, the area Radičevac, the most important biological and pomological traits of dogwood (Cornus mas L.), on randomly selected sample of 30 genotypes, were observed with the aim to recognize biological diversity of this population. Based on important properties of vegetative and generative organs such as tree, fruit branches and flowers, pomological fruit properties and yielding, genotypes 1, 5, and 20 were the most valuable and investigation on them will continue.

U populaciji Stare planine dren (Cornus mas L.) spada u grupu najzastupljenijih vrsti voćaka, jer se po metodi Braun-Blanquet - sreće u 80-100% proučavanih površina, a po pokrivenosti na 25-50% površina. Na Staroj Planini, na potezu Radičevac, proučavane su najvažnija biološko-pomološka svojstva drena (Cornus mas L.), na slučajno odabranom uzorku od 30 genotipova, a sa ciljem sagledavanja biološke divergentnosti ove populacije. Na osnovu važnijih pokazatelja vegetativnih i generativnih organa kao što su stablo, grančice i cvet, pomoloških parametara ploda, i rodnosti, najbolja biološko-pomološka svojstva u izučavanoj populaciji pokazali su genotipovi 1, 5 i 20, zbog čega će se njihovo proučavanje dalje nastaviti.
