Abstract

Fresh seed derived from a population of non-radiate groundsel from the Coto Donana, Spain, showed strong innate dormancy over a wide temperature range; fresh seed of groundsel from Dundee, Scotland, exhibited >80% germination at 20°C. Dormancy may be caused by an inhibitor present in the embryo or seed coat which might act by preventing the synthesis or liberation of gibberellins required for germination. The innate dormancy exhibited by seed of non-radiate Mediterranean S. vulgaris, enables the species to adopt a winter annual life cycle, typical of Mediterranean ephemerals.
