Abstract

The study was conducted to develop the substitute substance of STS (silver thiosulfate) with cut Lilium longiflorum ‘Georgia’. Ethylene inhibitors, AVG (aminoethoxyvinyl glycine) 0.6mM, AIB ($\alpha$-aminoisobutyric acid) 5mM, and ethanol 2% treatment prolonged vase life longer than STS treatment. Anther removal treatment was more effective than stigma removal treatment. Combination treatment of GA_3 and BA 25mg․L^-^1 was very effective for the inhibition of leaf yellowing. Chlorophyll content was maintained for a long time in contrast with control. The selected treatment for the prolongation of vase life was AIB 5mM + GA_3 25 mg․L^-^1 + BA 25 mg․L^-^1 + anther removal treatment.

본 실험은 최근 환경오염물질로 구분되어 사용이 금지된 STS (silver thiosulfate) 대체물질을 개발하여 절화 나팔나리의 수명을 연장하고자 실시하였다. 에틸렌 발생억제제의 경우 AVG(aminoethoxyvinyl glycine) 0.6mM, AIB(α-aminoisobutyric acid) 5mM, ethanol 2% 농도에서 꽃의 수명이 가장 길었고 STS 처리구와 같았다. 나팔나리의 꽃 기관중 에틸렌 발생기관인 주두와 약을 제거한 실험에서는 약 제거 처리구가 가장 효과적이었다. GA3와 BA를 각각 25mg･L-1 농도로 처리한 경우 대조구에 비해 잎의 엽록소 함량이 장기간 유지될 수 있었다. 최종적으로 선발된 AIB 5mM + GA3 25mg･L-1 + BA 25mg･L-1 + 약 제거 처리구는 대조구에 비해 에틸렌의 발생량이 현저하게 감소하였으며 또한 꽃의 수명도 3일 연장되었다.
