Titre : Embryological features, pollen and seed viability of Arnica montana (Asteraceae) – a threatened endemic species in Europe Type de document : Imprimé Auteurs : Elina Yankova-Tsvetkova ; Petka Yurukova-Grancharova ; Georgi Baldjiev ; Antonina Vitkova Année de publication : 2016 Article en page(s) : 39-44 Langues : Anglais (eng) Mots-clés : Arnica montana L., 1753 Résumé : The embryological features, mode of reproduction and reproductive capacity (pollen and seed viability) on two naturalized populations of Arnica montana in Bulgaria were studied. The embryological study shows that A. montana is a facultative apomictic species in which sexual reproduction predominates. In this species, it was established that there is a comparatively high viability of the mature pollen and embryos, which enables the successful realization of its reproductive capacity. The results of the study on A. montana reveal that both sexual and asexual vegetative reproduction with rhizomes undoubtedly play more important roles than the apomixis (namely diplospory) for support and preservation of the populations.
