Phenolic compounds as chemical markers of low taxonomic levels in the family Poaceae

The spectra of non-structural phenolics in herbage were used to study genetic affinity in polyploid complex of Dactylis L., next in complex of octoploid brome species, and in red fescue cultivar collection. The diploid (2n = 14) subspecies of Dactylis revealed distinct differences from the tetraploid (2n = 28) ones as a clearly specialized group. In the genus Bromus the affinity bounds of the species inside the section (e.g. Ceratochloa) were...
