Abstract

This study was carried out to elucidate the influence of gibberellin soak and seed dressing with Toros wp. on the dehiscence of Eleutherococcus senticossus seeds. $GA_3$ treatment was effective on promoting after-ripening seed of Eleutherococcus senticossus whose concentration was higher until $500\;mg{\cdot}L^{-1}$, after-ripening period became shorter. But rotting percentage increased gradually up above $500\; mg{\cdot}L^{-1}\;GA_3$After all, $300\;mg{\cdot}L^{-1}\;GA_3$ was the most effective treatment for promoting after-ripening seed. Dressing treatment with Toros wp. on seeds reduced the dehiscent rate of E. senticosius. by suppressing activity of fungi living on the endocarp surface of seed.

가시오갈피의 종자 후숙을 촉진하고, 부패율을 낮추기 위하여 후숙전 Gibberellin 처리농도 및 침지시간, 토로스 분제를 사용한 종자소독처리에 따른 가시오갈피 종자의 배 배달 및 개갑특성을 조사하였다. 가시오갈피 종자 후속 전 적정 $GA_3$ 처리농도가 높아짐에 따라 개갑속도가 빨라지는 경향을 나타냈으며, $500\;mg\;{\cdot}\;L^{-1}$ 처리구 이상에서는 부패율 급증에 따른 개갑율 감소현상이 확인되어 부적합한 것으로 나타났다. 후숙전 종자소독처리는 가시오갈피 종자개갑에 유용한 미생물 (Trichoderma, Aspergillus 속 등)의 활동을 억제하여, 후숙과정을 지연시키는 것으로 확인되었다. 대조구 (물 24시간 침지)에 비해 $GA_3\;300\;mg\;{\cdot}\;L^{-1}$ 24시간 침지처리구에서 개갑기간이 40여일 단축되었으며, 저온휴면타파처리 ($5^{\circ}C$, 70일)후 개갑종자의 85% 이상이 정상적으로 발아하는 것이 확인되었다.
