[Objective] To explorer of the germination characteristics of Cardamine hupingshanensis seeds and provide guidance for its introduction and cultivation. [Method] The ecological environment investigation of Cardamine hupingshanensis was carried out in Hupingshan National Nature Reserve, and the seeds germination rate were determined in different conditions including light, temperature, pH value and storage. [Results] In Hupingshan National Nature Reserve, Cardamine hupingshanensis seeds have no dormancy, and can germinate naturely in the Hupingshan habitat. Their germination characteristics were fully adapted to the low-temperature streams environment. The germination rate was higher at the temperature from 15 ℃ to 25 ℃, and the germination rate and speed decreased quickly at the temperature of more than 25 ℃. The germination of Cardamine hupingshanensis seed was not susceptible to the pH value. Light also have an impact on seed germination, but was not the decision condition. The seed longevity of Cardamine hupingshanensis was about 80 d under conditions of natural ventilation. [Conclusion] The temperature and light factors should be considered on artificial breeding, and the temperature of germination process should not exceed 25 ℃. Moreover, the seeds should be saved under low-temperature drying conditions.
