초록

본 연구는 국내에서 육성된 절화용 거베라 19품종의 우량묘 생산을 위하여 적정 식물생장조절물질의 종류 및 조합을 알아보고, 국내 육성품종의 우량묘 대량생산을 위한 기초 자료로 제공하고자 실시하였다. 우량묘 생산을 위한 생장조절물질의 종류 및 조합에서 NAA와 BA의 혼용보다는 BA와 Kinetin의 흔용조건에서 대량증식이 양호하였다. 대량증식이 양호한 BA와 Kinetin의 혼용조합에서 품종에 따라 대량증식의 조건이 달리 나타났다. 19개 품종 중 대부분은 BA 1.0mg/L + Kinetin 0.5, 1.0 mg/L의 혼용조건에서 우량묘의 대량증식이 양호하였다. 그러나 '선녀', '옥샘', '피니', '핑크라이트'등 4개 품종은 BA의 농도가 높을수록 투명화묘의 발생이 많이 나타났다. 이들 품종들은 BA 0.5 mg/L + Kinetin0.1 mg/L의 흔용처리구에서 우량묘의 대량증식이 가능하였다. 생체중과 건물중은 BA 0.5 mg/L + Kinetin 0.1, 0.5mg/L 의 혼용 처리구에서 양호한 경향이었다. 엽병장에서는 전 처리구 모두 큰 차이는 없었다. 투명화묘의 조직관찰결과, 투명화묘의 기공형태는 정상묘에 비하여 기공이 열려있는 상태로 돌출되어 있었으며, 둥근 모양을 하고 있었다.

This study was carried out to obtain information about the valuable combination and concentration to produce good plants of cut gerbera flowers of 19 domestically - bred gerbera cultivars. BA and kinetin combination is more effective than NAA and BA combination to produce good plants and mass propagation of domestically - bredgerbera cultivars. Normally almost of 19 cultivars, mass propagation was more effective on the medium containing 1.0 mg/L BA + 0.5, 1.0 mg/L kinetin. But some cultivars, 'Sunnyeo', 'Oksaem','Piny', and 'Pink Light', vitrified plants were induced on MS medium high level of BA concentration(BA 1.0 mg/L), in comparison with those on the medium with low level of BA(0.1 mg/L).Fresh and dry weight, more effective on the medium containing BA 0.5 mg/L . Kinetin 0.1, 0.5 mg/L. Anatomical investigation of vitrified leaf, stomata of vitrified leaves were circular and inflated, where-as those of normal leaves.
