Nucleolar number variation in Fritillaria (liliaceae) taxa from Greece

The current study aims to estimate the most frequent number of nucleoli in taxonomically interesting Fritillaria species. Silver nitrate staining is applied using a modified protocol 14 taxa and one hybrid from 17 populations Greece. This first report for all studied here. In general, ranges 0-8, with pontica F. theophrasti characterised by greatest observed nucleoli. results reinforce classification intriguing taxa, such as sporadum theophrasti, distinct species, even though they have recently been considered synonyms ehrhartii pontica, respectively.
