Abstract:
Object To provide the theoretical basis for the artificial planting of Hypericum perforatum L., the effects of light, gibberellin and ethephon on the germination of H. perforatum seeds were studied. Methods The method of direct germination was used. Results The seeds germinated to 79% in the light, while didn't germinate in the dark. Gibberellin and ethephon not only promoted the germination in the light, but also induced the germination in the dark. But ethephon inhibited the growth of seedling radicals severely. Conclusion The seed of H. perforatum is light-dependent seed, its light-dependence is related to gibberellin and ethephon.
