Breeding system of the subantarctic plant species Pringlea antiscorbutica R. Br. And search for potential insect pollinators in the Kerguelen Islands
International audience The reproductive biology of Pringlea antiscorbutica R. Br. (Brassicaceae), an endemic species from the southern Indian Ocean islands, is investigated here. Controlled crosses were performed between plants grown in a common garden on the Kerguelen Islands. Searching for potenti...
