The germination rate and longevity of seeds of Gastrodia elata Blume have been observed for 48 weeks using Mycena osmundicola strain H-21, one of fungi stimulating seed germination. Storage condition of post-harvest seeds was observed in the different temperature ranges of $-30^{circ}C,;-5^{circ}C,;5^{circ}C;and;30^{circ}C$ for 48 weeks. After storage period of 48 weeks, the germination rate of G elata was 65.7% at $5^{circ}C$ and 71.6% at $-5^{circ}C$, respectively. Although the germination rate of G. elata was 77.3% for 11 weeks at $25^{circ}C$, the germination rate had been decreased gradually to 49.3% at 13 weeks, 0.3% at 23 weeks and then 0% at 25 weeks. The germination rate was reached to the level of 10% for 2 weeks at $-30^{circ}C$ and then decreased to 0%.
