Objective To accelerate the artificial domestication of Disporum cantoniense (Lour.) Merr.wild variety.Methods Based on previous tests for different sowing time in 2006 and for different covers and different gibberellin in 2007,4 different stratification time were adopted to raise seedlings from D.cantoniense seeds in 2011,including A (90 d,starting from December 6,2010),B (60 d,starting from January 6,2011),C (30 d,starting from February 6,2011) and CK (0 d,no stratification).All seeds in treatment A,B,C and CK were planted in the soil on March 6,2011.Results Cold stratification could improve the emergence rate and emergence speed of seedlings,especially 90 days cold stratification,followed by 60 and 30 days.Conclusion Cold stratification could enhance the emergence rate of D.cantoniense wild seeds.
