초록

카네이션의 약배양 기술을 확립하고자 저온 전처리, 암처리, Ficoll처리가 약배양에 미치는 효과를 조사하였다. 약배양에 적합한 화분의 발육단계인 1핵기 소포자 전후 화분의 약을 가지는 카네이션 화뢰의 직경은 4~6mm이었다. 카네이션 약배양 후 캘러스 형성과 배양 후 약의 반응에 가장 효과적인 저온전처리 기간은 7일이었다. 명배양하는 것보다 암배양하는 것이 캘러스 형성과, 형성된 캘러스로부터 root 분화에 효과적이었다. Ficoll처리는 캘러스 형성에 큰 효과는 없었지만, 형성된 캘러스로부터 신초와 root가 분화되었다.

These studies were carried out to investigate the effects of cold pretreatment, dark condition, and Ficoll on the callus formation and organ differentiation in anther culture of carnation for the purpose of settling the techniques of anther culture of 'Rony' carnation. Diameter of flower buds containing anthers with microspores before or after uniuncleated stage was between 4 and 6 mm. A high percentage of callus formation and responding anthers were achieved by low temperature pretreatment at $4^{\circ}C$ for 7 days. Callus formation was promoted under dark condition. Roots were differentiated from calli formed under darkness. Ficoll didn't promote callus formation but promoted differentiation of shoots and roots.
