| Abstract: | Genome size was assessed by flow cytometry in 33 species belonging to seven genera of the tribe Cardueae (Asteraceae), which can be grouped in three taxonomic complexes. 2C nuclear DNA content ranged from 1.49 to 16.98 pg, which is more than elevenfold variation. Genome size correlated well with some karyological traits. Nuclear DNA amount variations also have systematic and evolutionary implications and/or are linked to adaptations to ecological conditions. |
