Abstract:: Effects of chilling and gibberellin on release dormancy and flowering regulation of Lilium pumilum were studied by bulbs of Lilium pumilum which were refrigerated for 15，30，45，60 days at 4℃ and for 45 days at 4℃ combined treatment with 200 mg/L gibberellin.The results showed that the longer refrigerating，the shorter times of the bulb dormancy required.Treatment with 200 mg/L gibberellin compared to the control，3 days could be shorten for the time of release dormancy，5 days could be shorten from building stage to squaring stage.The bulbs of Lilium pumilum treated with gibberellin could accelerate the bulbs to release dormancy，bloom earlier.
