Abstract:: Fresh Duchesnea indica seeds were experimented by different ways such as distilled water, tap water, H₂SO₄, HCl, NaOH, cleanser essence, illumination, germfree culture, different culture medium or scrubing part of seed capsule etc. The results showed that there were seed dormancy and different dormancy reasons in fresh Duchesnea indica. But, seed dormancy could be breaken in combination condition of heat and NaOH and illumination and so on. The germination percentage was over 90%. The reason of seed dormancy needed to be deeply researched.
