Název v původním jazyce

Karyo-taxonomic study of the genus Pseudolysimachion (Scrophulariaceae) in the Czech Republic and Slovakia

Popis výsledku v původním jazyce

Flow cytometry was used to determine ploidy levels in the Czech and Slovak taxa of the genus Pseudolysimachion. In P. maritimum and P. spicatum two cytotypes were found: diploid (2n=2x=34) and tetraploid (2n=4x=68). In both species the tetraploid cytotype predominated. The two cytotypes of P. maritimum have no taxonomic significance because ploidy level is not obviously correlated with morphology, distribution of pattern or ecology. Tetraploid populations of P. spicatum belong to two morphologically different subspecies, subsp. spicatum and subsp. fischeri. The diploid cytotype should be provisionally classified as a third subspecies of P. spicatum, which is morphologically similar to the Asian subsp. porphyrianum. Only diploid plants of P. orchideum were found. One diploid population sample of P. spurium subsp. foliosum and one tetraploid sample of P. incanum subsp. pallens were also analyzed. In addition, three tetraploid populations of hybrid origin were investigated.
