RAPD (random amplified polymorphic DNA) analysis was examined to detect variation of in vitro cultured 30 rhizomes of Cymbidium goeringii Lindley and Cymbidium kanran Makino, with long-term (8 years) subculture, respectively. Out of 151 DNA bands detected, the 40 were polymorphic with a polymorphic ...

난과 (Orchidaceae) 식물이란? | 식물학상 단자엽식물 중 가장 진화된 식물인 난과 (Orchidaceae) 식물은 전 세계적으로 800속, 20,000~ 25,000 종으로 분화되어 있으며(Arditti, 1992), 우리나라 에는 29속 92종 11변종이 있다(Chung et al., 1985). | |
난과 (Orchidaceae) 식물은 전 세계적으로 어느 정도 분화되어 있는가? | 식물학상 단자엽식물 중 가장 진화된 식물인 난과 (Orchidaceae) 식물은 전 세계적으로 800속, 20,000~ 25,000 종으로 분화되어 있으며(Arditti, 1992), 우리나라 에는 29속 92종 11변종이 있다(Chung et al., 1985). | |
식물 기내 배양의 이점은? | 난은 대부분 타식성 식물이기 때문에 유전인자의 조성이 heterozygous한 형태이며, 이종속간에도 교잡이 잘되기 때문에 유전인자가 매우 다양한 식물이다(Garay and Sweet, 1974; Harn, 1973). 식물의 기내배양은 체세포분열을 통한 식물체의 재분화로 동질성을 지닌 클론을 대량으로 얻을 수 있다는 이점을 가지고 있으나 기내배양 과정 중 유전적 변이가 일어남으 로써 종종 원치 않는 방향으로 재분화식물체의 증식이 이루어진다(Karp, 1991; Scowcroft et. al. |
