Research on Dormancy and Germination Characteristics of Cercis canadensis 'Forest Pansy' Seeds
The seeds of Cercis canadensis 'Forest Pansy' were used as research materials. The internal structure,water absorption and germi-nation of the seeds were observed. The results showed that the seeds of Cercis canadensis'Forest Pansy' had double dormancy. The seeds were etched with concentrated sulfuric acid for different time and then treated with gibberellin of different concentrations. The results showed that the seed dormancy could be broken effectively and the seed germination of Cercis canadensis'Forest Pansy' could be promoted. It turned out that the best treatment was acid etching with concentrated sulfuric acid for 25 min and soaking with 300 mg/L gibberellin,and the germination rate was (60.0±3.3)％.
