Abstract

Peucedanum japonicum $T_{HUNB}$ used as a edible and medicinal plants was investigated for in uitro regeneration. Callus formation occurred on leaf and stem explant cultures and showed spontaneous embryogenic and organogenic capability on MS basal medium supplemented with 0.1~5 mg/L NAA and 0~10 mg/L BA in dark. The regeneration was highest on the condition supplemented with 2.5 mg/L NAA and 10 mg/L BA. Development of the somatic embryo progressed through the globular, heart-shaped, torpedo-shaped and cotyledonary stage, typical of zygotic embryos. When the first somatic embryos was cultured on the medium supplemented with 0.2 mg/L NAA, secondary somatic embryo were induced with higher frequency on the hypocotyl then on the cotyledon and root.t.

식용 및 약용으로 사용되는 갯기름나물의 기내배양을 통한 재분화율을 조사하였다. 캘러스는 잎과 엽병의 절편체에서 발생하였고 0∼5 mg/L의 NAA와 0∼10 mg/L BA가 첨가된 MS 기본배지에 치상하여 암배양 결과 자발적인 배 분화와 기관 분화를 보여주었으며 2.5 mg/L NAA와 10 mg/L BA의 조건에서 재분화율이 가장 높았다. 체세포 배의 발생양상은 구형, 심장형, 어뢰형을 거쳐 자엽 단계로 발달하여 전형적인 접합자 배의 모습으로 발달하였다. 배 발생한 일차 체세포배를 0.2 mg/L의 NAA가 첨가된 배지에서 배양하였을 때, 이차 체세포배가 발생하였으며 주로 일차 체세포배의 배축과 하배축에서 많이 발생하였고 그 다음으로 자엽이나 뿌리 부분에서 발생하였다.
