Somatic Embryogenesis and Plant Regeneration in Suspension Cultures of Aralia elata S
두릅캘러스의 현탁배양에서 체세포배발생과 식물체 재분화
Abstract
This study was carried out to investigate the possibility of plant regeneration through somatic embryogenesis in suspension culture of Aralia elata S. Callus was induced from the explants of leaf and petiole cultured in the MS media containing 2,4-D and TDZ. More embryogenic calli were formed from petiole and with combination treatment of 24-D and TDZ. The quarter strength MS medium was effective for increasing number of somatic embryos. Mannitol supplemented to the quarter strength MS medium, reduced somatic embryo formation but inositol increased. Normal plantlets(86%) were regenerated from mature somatic embryos in MS basal medium and 50% of those survied when transplanted to the vermiculite in greenhouse.
두릅나무의 현탁배양에서 체세포배 형성과 식물체 재생의 가능성을 알아보고자 배발생 캘러스 유도조건과 배지농도 및 삼투조절제의 영향을 조사하였다. 어린 엽보다 엽병에서 캘러스 유도가 양호하였고, 2,4-D 단독처리보다는 2,4-D 1.0, 2.0 mg/L + TDZ 0.1 mg/L 처리에서 캘러스 유도량과 배발생 캘러스의 빈도가 가장 양호하였다. MS 기본배지의 농도를 1/4으로 줄인 1/4
