Callus was induced from mature embryos of Alstroemeria cv. Butterflycultured on MS medium supplemented with 2·0 or 4·0mg dm3 2,4D or picloram and incubated at 25°Cin the dark. The effect of auxin concentration and precultureof embryos was studied. Callus was capable of regeneration aftertransfer to MS medium containing 4.0 mg dm°3 BAP. Shootsand whole plantlets were regenerated. The effect of growth regulators,used in the callus induction medium and the regeneration medium,on plant regeneration was studied Key words: Alstroemeria, callus, plant regeneration. 相似文献

Interaction Between Cryopreservation, Rewarming Rate and Seed Humidification on the Germination of Two Spanish Endemic Species 总被引:2,自引:1,他引:1

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. 相似文献
