In this experiment, seeds of Echinacea purpure were used as materials to investigate the effects of several factors on the germination and seedling growth. The results showed that 6-BA, SNP and NAA all promoted the germination and seedling growth of E. purpure seeds. The best effects were obtained, when application of soaking treatment for seeds with 5 mg/L NAA before inoculating them onto MS media supplied with 0.1 mg/L IAA, the highest seed germination rate was 86.7%, and the best rooting rate of seedlings was 83.3%. However, seed sprouting and development of seedling were inhibited, when Mn 2+ was added into mediums.
