Abstract
An optimization in vitro seed germination was established by using triphenol tetrazolium chloride (TTC) test, which has been known as two rare orchids (Gastrodia verrucosa Blume and Hetaeria sikokiana Tuyama) in Jeju island. We have established proper NaOCl treatment for in vitro germination of G. verrucosa and H. sikokiana through TTC test. In the case of H. sikokiana, seed viability through TTC test was high with 95% in control. However, NaOCl 1% treatment for 30 minutes showed the highest embryo swelling rate to seed viability. Likewise, swelling formation of embryos, diameter of embryos, protocorm formation and diameter of protocorms of G. verrucosa was 87%, $59{\mu}m$, 91% and $138{\mu}m$ through NaOCl 1% treatment for 30 minutes. This result will be applied on the basic information for improving in vitro seed germination rate of G. verrucosa and H. sikokiana.
