Contribution to knowledge about nuclear DNA amounts in the family Asteraceae: first assessments in one genus and 12 species, with chromosome counts for three taxa

We present in this paper the first assessments, made by means of flow cytometry, of nuclear DNA amounts in one genus, 11 species, and one variety (including the first data from wild material in the case of one of the species), all of them from the family Asteraceae. Chromosome numbers are provided for three of these taxa, the presented material including new data for one species. These data complement existing information on plant genome size in the largest plant family
