Abstract

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.

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.
