Abstract:: In order to relieve wild seed dormancy of Saposhnikovia Divaricata and to improve the germination capacity，different concentrations of gibberellin(GA₃)were selected to treat the seeds.The results showed that gibberellin could improve the germination rate and germinating performance of the wild Saposhnikovia Divaricata seeds.Soaked in 500 mg/L and 400 mg/L GA₃ for 24 h，the seed germination rate increased 27.85% and 26.29% than the control，and germinability increased 63.86% and 64.02% respectively；treated with 500 mg/L，400 mg/L，300 mg/L，200 mg/L and 100 mg/L GA₃ for 36 h，the seed germination rate increased 22.45%，22.34%，23.79%，12.30% and 5.17% respectively than the control，and germinability increased 43.34%，45.89%，40.69%，38.32% and 32.04% respectively.Seed soaking time should more than 24 h，the suitable concentration was 400 mg/L；if soaked 36 h，the concentration was 300 mg/L.
