Abstract

Off-white, friable embryogenic calluses were formed on the internal integument of mature seeds of yuzu (Citrus junos) cultured on Murashige and Skoog's basal medium at a frequency of 1.2%. Embryogenic calluses were proliferated when cultured on medium with 1 mg/L 2,4-D. Upon transfer to medium with 0.1 mg/L kinetin, embryogenic calluses produced numerous somatic embryos. Embryogenic suspension cultures were established by placing embryogenic calluses into liquid medium with 1 mg/L 2,4-D. When plated onto medium with 0.5 mg/L ABA, embryogenic cells developed into somatic embryos at a high frequency, and then regenerated into plantlets. Plantlets were successfully transplanted to potting soil and grown in a greenhouse.

유자의 성숙종자를 MS 기본배지에 치상하여 종자의 내피에서 주심조직 유래의 희고 부서지기 쉬운 배발생캘러스가 1.2%의 빈도로 형성되었다. 이 캘러스는 1 mg/L 2,4-D를 첨가한 MS배지에서 증식되었다. 증식된 캘러스를 0.1 mg/L kinetin을 첨가한 MS 배지에 옮겼을 때 많은 수의 체세포배가 형성되었다. 배발생캘러스를 1 mg/L 2,4-D를 첨가한 액체 배지에 넣어 배발생 현탁배양계를 확립하였다. 배양된 현탁배양세포를 0.5 mg/L ABA를 첨가한 고체배지에 평판하였을 때 높은 빈도로 체세포배로 발달하였으며 MS 기본배지 혹은 1 mg/L kinetin 첨가배지에서 소식물체로 발달하였다. 소식물체는 성공적으로 토양으로 옮겨서 온실에서 육성되었다.
