The shortest stratification period needed for breaking dormancy was chilling at 4℃ for 4 mo (germination percentage 40.7±3.1%) or combined stratification for 5 mo (2 mo of 30/20℃ followed by 3 mo of 4℃ stratification, germination percentage 40.1±4.2%).

以4℃层积打破种子休眠所需之最短时间为4个月（发芽率40.7±3.1%），而组合层积需时最短者为5个月（20/30℃层积2个月再入4℃层积3个月，发芽率40.1±4.2%）。
