Abstract: This study deals with the seed germination for Onopordum tauricum (Asteraceae). The cypselae were collected from two populations in the Marche and Umbria Region (Italy). The highest germination value (93.6%) was obtained after 24 hours of soaking in a 500 ppm GA3 solution and then incubated at a constant temperature of 20°C with a 12/12h light-dark photoperiod.

Key words: Onopordum, dormancy-breaking, gibberellin, milk-clotting agent.
