Abstract


    In this study we report new flow cytometric data on genome size in about fifty species from the Balkan flora, frequently with many populations of each. The following genera are represented: Acer L., Centaurea L., Iris L., Leontodon L., Lilium L., Reichardia Roth, Rhamnus L, together with the gymnosperms Juniperus L. and Pinus L. Although this flora, and especially that from Central Dinaric Alps, is very rich in endemic species, unfortunately it has never been studied with respect to 2C DNA values. This parameter gives an early indicator of polyploid series, of instabilities linked to aneuploidy, hybridisation and finally speciation in a complex of related species. These cytometric analyses also included an estimation of base composition for many species, using Godelle’s simple fluorometric method(1).
