본 연구는 기존에 절화용으로 개발되지 않았던 암대극을 새로운 관상식물로 개발하기 위해 수행되었다. 실험은 보존용액에 따른 절화 암대극의 영향을 구명하고자 수분흡수율, 절화수명, 상대생체중을 조사하였다. 수확 후 절화는 8-hydroxyquinoline sulfate (8-HQS) 10, 50, 100 ㎎·L-1, silver thiosulfate (STS) 0.1, 0.2 mM, Chrysal, Floralife의 보존용액에 처리 되었다. 실험은 온도 22.6℃, 상대습도 45%, 일장 9/15h, 광도 9.89 μmol·m-2·s-1 환경에서 수행되었다. 절화 암대극의 수분흡수율은 8-HQS 10 ㎎·L-1 보존용액에 처리 시 무처리된 절화보다 유의하게 높게 측정되었다. 그러나 절화 암대극의 수명은 무처리와 8-HQS 10 ㎎·L-1 보존용액 처리 시 차이가 관찰되지 않았다. 절화 수명은 STS 보존용액 처리 시 처리농도가 증가함에 따라 감소하였다. 절화 암대극의 상대 생체중은 상업용 절화수명연장제인 Chrysal 및 Floralife 보존용액 처리 시 무처리 보다 유의하게 감소하였다. 이러한 결과는 절화 암대극의 사용에 있어 유용한 자료가 될 것이다.

This study was conducted with the purpose of examining the suitability of Euphorbia jolkinii Boiss. as cut flower, so that it may be introduced as a new ornamental crop. For this purpose, effect of various holding solutions on vase solution uptake rate, vase life, and relative fresh weight of cut flowering branches of E. jolkinii was examined. After harvest, cut branches were treated with 10, 50, and 100 ㎎·L-1 of 8-hydroxyquinoline sulfate (8-HQS), 0.1 and 0.2 mM of silver thiosulfate (STS), Chrysal, and Floralife. The cut branches of E. jolkinii were placed under the environmental conditions maintained at air temperature of 22.6°C, relative humidity of 45%, and 9/15h photoperiod that was controlled using fluorescent lamps (light intensity of 9.89 μmol·m-2·s-1). A holding solution containing 10 ㎎·L-1 8-HQS was found to be significantly effective for vase solution uptake rate compared to control, 50 ㎎·L-1 8-HQS, and 100 ㎎·L-1 8-HQS treatments. However, no significant difference was found in vase life between the branches treated with 10 ㎎·L-1 8-HQS holding solution and branches of the control group. Increasing holding solution concentrations of STS was found to have negative effect on the vase life of cut E. jolkinii branches. Relative fresh weight of cut E. jolkinii branches were significantly decreased by two commercial holding solutions, Chrysal and Floralife. It is expected that these results would aid further studies on utilization of E. jolkinii as cut flower crop.
