Název v původním jazyce

Mating interactions between coexisting diploid, triploid and tetraploid cytotypes of Hieracium echioides (Asteraceae)

Popis výsledku v původním jazyce

Only diploids were found in progeny from 2x x 2x crosses. The other types of crosses yielded more than one cytotype in progeny, however, one cytotype predominated in each cross type: diploids (92%) in 2x x 3x crosses, tetraploids (88%) in 3x x 2x, triploids (96%) in 2x x 4x crosses, triploids (90%) in 4x x 2x crosses, tetraploids (60%) in 3x x 3x crosses, pentaploids (56%) in 3x x 4x crosses, triploids (80%) in 4x x 3x crosses and tetraploids (88%) in 4x x 4x crosses. No aneuploids were detected among karyologically analysed plants. Unreduced egg cells production was detected in triploids and tetraploids, on the contrary, formation of unreduced pollen was recorded only in two cases in triploids. Triploid plants produced x, 2x and 3x gametes, however, in male gametes predominated x (92%) gametes whereas in female gametes predominated 3x (88%) gametes.
