Abstract:
In this paper,the effects of different treatments on
Bupleurum dracaenoides Huan C.Wang,Z.R.He&H.Sun seed germination were studied.Results showed that the optimum germination temperature for
B.dracaenoides was 20℃.Treatment with 100 mg/L of GA
3,0.5% KMnO
4,and 3% H
2O
2 improved seed germination,but did not advance seed germination and emergence time.Microwave radiation significantly improved the seed germination rate,with 25 s found to be the optimal radiation time.The most effective ultraviolet radiation treatment time for seed germination was 0.5 h,with a germination rate of 81%.When the ultraviolet radiation time was gradually increased,the germination potential of seeds was inhibited to different degrees.Thus,optimal treatment to maximize
B.dracaenoides seed germination was to soak seeds in 100 mg/L of GA
3 for 12 h at a temperature of 20℃.
