Abstract

A propagation for Fatsia japonica using axillary bud explants were established. Cultures were initiated from axillary bud explants on MS medium supplemented with IAA $(1,2,3\;mgl^{-1})$, 2,4-D $(1,2,3\;mgl^{-1})$ or NAA $(1,2,3\;mgl^{-1})$ in combination with BA $(0.5\;mgl^{-1})$. The maximum shoot bud formation was obtained in MS medium supplemented with $0.5\;mgl^{-1}$ BA and $2;mgl^{-1}$ IAA after 4 weeks culture. The microshoot rooted within 4 week in MS medium containing $1.0\;mgl^{-1}$ IBA.

액아가 포함된 줄기절편을 $0.5\;mgl^{-1}$ BA와 함께 IAA, NAA, 2,4-D를 농도별 $(1,2,3\;mgl^{-1})$로 조합한 MS기본배지에 치상하여 신초를 유도하였다. 액아로부터 신초의 형성은 $0.5\;mgl^{-1}$ BA와 $2;mgl^{-1}$ IAA를 혼합처리한 배지에서 57%의 효율로 가장 높게 나타났다. 신초로부터 발근은 MS배지에 IBA를 $1\;mgl^{-1}$를 첨가하였을 때 가장 좋았다. 발생한 root의 길이는 평균 4주 후 약 4 cm로 측정되었다.
