토천궁의 줄기마디를 이용한 효율적인 삽목번식 기술을 개발하고자 수행한 시험결과를 요약하면 다음과 같다. 1. 삽목시는 8월30일 1~2마디삽목에서 발근율이 81%로 가장 높았고 발근상태도 양호하였다. 2. 삽수채취에 따른 수량감소는 주당경수의 50%채취에서 9%이하 였으나 100% 채취에서는 10~23%로 비교적 높았다 3. 삽목묘의 포장정식후 활착율은 9월25일 및 10월25일 정식에서 각각 85%, 87%로 높았으나 11월25일 정식에서는 28%로 낮았다. 4. 10a당 수량은 9월25일및, 10월25일 정식에서 각각 127kg, 120kg으로 높았다.
Ligusticum chuanxiong has been an important oriental crude drug and cultivated for a long time in Korea. Ligusticum chuanxiong has been vegetatively propagating crop without seed due to its sterility and would be an allodiploid derived from the hybridization of two allied species. Generally, vegetative propagation is more costly per unit propagule than sexual(seedling) propagation. This study was conducted to find out the techniques of mass propagation by stem cutting for reduced seedling cost. When cutted on August 30 with 1st to 2nd internode, its highest rooting percentage was 81 percent. Rhizome yield of plants cutted in 50 percent on September 1 decreased to 9 percent less than control (rhizome propagation). Rooting percentage of rooted cutting plants after field planting on October 25 was the highest being 87 percent. Rhizome yield with planting appeared 127 and 120kg/10a on September 25 and October 25, respectively.
