Abstract:
[Objective] To determine dormancy mechanism of Taxus mairei(Lemee et Levl.) S.Y.Hu ex Liu Seeds,the best method of dormancy breaking.[Method]The seeds were handled by lotic water or excitatory autacoid or cold-warm-cold stratification treatment or cold-warm-cold stratification treatment with excitatory autacoid,then compare withgermination inhibition of Brassica campestris seeds handling with water solution from the seeds after four dormancy breaking methods,to dertemine the best dormancy breaking method.[Conclusion] The best damancy breaking method was cold(4℃)—warm(23℃)—cold(4℃) stratification treatment with 0.05% gibberellic acid for 120 days.
