Abstract: | The effects of humidification, storage in liquid nitrogen (1or 30 d) and rewarming rate on seed germination were studiedin two Spanish endemics. Humidification resulted in higher germinationpercentages only in the species with hard covers, especiallyin slowly rewarmed seeds. In an experiment lasting 21 weeks,seeds stored in liquid nitrogen were removed for 10 min eachweek to mimic the withdrawal of samples from a seed bank; thishad no effect on germination.Copyright 1998 Annals of BotanyCompany Centaurea hyssopifolia,Limonium dichotomum, cryopreservation, cypsela, endemics, germination, humidification, seeds. |
