Abstract: [Objective] To provide a theoretical basis for scientific cultivation,a experiment was conducted to study the factors influencing germination of C. officinalis seeds.[Method] A filter paper bed within constant temperature and light was used.[Results] There were significant differences in germination of C. officinalis between different varieties,growing years,storage time,husking and tested temperature but threshing had no significant effect.[Conclusion] The optimum temperature for germination of C. officinalis seeds was about 20℃.Red type of C. officinalis was stronger than white type in germination capacity and cold resistance.Husking treatment improved germination capacity and the germination capacity of new seeds was higher than that of seeds stored over two year seeds.

Key words: Cyathula officinalis Kuan, seed, germination characteristics
