目的 研究光、赤霉素和乙烯利对贯叶连翘 Hypericum perforatum种子萌发的影响 ,为贯叶连翘的人工栽培提供理论依据。方法 直接发芽法。结果 贯叶连翘种子光下萌发率达 79%,而暗中不萌发。赤霉素和乙烯利不仅能促进种子光下萌发 ,而且能诱导种子暗萌发。但乙烯利处理对幼苗胚根生长有明显的抑制作用。结论 贯叶连翘种子为需光种子 ,其需光性与赤霉素和乙烯利有关。

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. Gibberell in 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.
