[Objective] To study the effects of cycocel(CCC) on growth and hypericin content of Hypericum perforatum L..[Method] Different concentrations of CCC were sprayed on Hypericum perforatum L.to determine the dynamic changes of growth morphology,chlorophyll fluorescent characteristics and hypericin content of Hypericum perforatum L..[Result] The results showed that the growth of Hypericum perforatum L.was inhibited by CCC,while the content of hypericin was improved significantly.The photosynthetic fluorescence effect of Hypericum perforatum L.could be regulated by appropriate concentration of CCC.[Conclusion] The production and medicinal content of Hypericum perforatum L.can be improved by proper concentration of plant hormone in large scale production and cultivation.In this study,physiological growth of Hypericum perforatum L.was regulated by different concentrations of plant hormone with chlorophyll fluorescence as index for the first time,in order to provide an enlightening insight for the safety production of Chinese medicinal herb.
