Glaucium flavum, Papaveraceae, seed dispersal, dormancy, germination, synaptospermyAbstract
Many plant species produce two kind of seeds, dispersed seeds and non-dispersed seeds. Generaly, dispersed seeds have no dormancy while non-dispersed seeds have. In the present paper, this hypothesis is tested with Glaucium flavum seeds, through an experimental framework, which also included inter- and intraindividual variation. Results do not sustain the predictions. Dispersed seeds are more dormant than the others. In this species, dormancy in dispersed seeds must be consider with synaptospermy. Dormancy can be an adaptation to seedling competition.
