Abstract

Chromosome number and karyotype are determined for three species: Scorzonera parviflora  (Asteraceae) (2n=14) Silene noctiflora (Caryophyllaceae) (2n=24) and Ranunculus repens (Ranunculaceae) (2n=32). Idiogram was prepared for each species. Symmetrical karyotypes were class 1A in Scorzonera parviflora, class 2A in Silene noctiflora and class 2B in Ranunculus repens.Karyotype formula were 7m  inScorzonera parviflora, 8m+ 4sm in Silene noctiflora  and 13sm+3m in Ranunculus repens.
