Karyotaxonomic analysis of supramontane populations of species of the genus Astragalus in Slovakia
The authors have drawn the inference of the presentation of supramontane species as floristic elements or geoelements as well as their glacial and postglacial evolution on the basis of own karyological analyses of native supramontane species. More advanced classification and interpretation methods and techniques are required for investigation of Astragalus alpinus group, Astragalus penduliflorus and particularly Astragalus australis auct. Within the Slovakian part of Western Carpathians, both Astragalus alpinus and Astragalus penduliflorus have diploid chromosome numbers 2n = 16. In Astragalus australis auct. in the territory only hexaploid populations 2n = 48 have been found.
