본 연구는 수출용 절화 백합 ‘Woori Tower’의 건식수송과 습식수송에 따른 품질을 비교하고, 절화수명 연장 및 품질 향상을 위한 적정 습식용액을 구명하고자 수행하였다. 실험재료로는 longiflorum 계통의 절화 백합 ‘Woori Tower’(Lilium longiflorum ‘Woori Tower’)를 사용하였다. 처리는 건식(dry transport, DT)과 습식용액으로 수돗물(tap water, TW), Chrysal AVB(C. AVB) 1mL·L-1, Chrysal SVB(C. SVB) 1pill·3L-1, 1-MCP kit(1-MCP) 2mg·L-1, GA 4+7 + BA 100mL·L-1, Vital Oxide(V.O) 2mL·L-1, H2 water(HW) 1.5mg·L-1으로 하였다. 조사 결과, 소비자 단계(실험 7일)에서 1번화와 2번화는 모두 만개하였으나 처리 간의 유의한 차이가 없었다. 3번화의 경우 C. SVB 처리구와 GA4+7 + BA 처리구만 만개하였으며, 대조구와 TW 처리구에서 불개화 현상이 나타난 것으로 조사되었다. 절화수명 조사결과, C. SVB 처리구는 9.5일, GA4+7 + BA 처리구는 9.0일로 대조구보다 1.8 ‑ 2.3일 연장되었으며, 위조 및 꽃잎 탈리와 엽황화가 다소 적게 발생되었다. 특히, C. SVB 처리구는 생체중 변화율이 높게 유지되었고, 수분균형이 실험 9일에 부(-)의 값으로 떨어지며 품질 유지에 효과적이었다. C. SVB 처리구는 건식수송과 TW 처리구보다 박테리아가 적게 검출되었으며, 에틸렌 발생량 또한 적게 나타나 절화수명 및 선도유지에 효과적인 것으로 판단된다. 따라서, 습식수송이 건식수송에 비하여 절화 백합의 품질 향상에 효과적인 것으로 판단된다. 특히, 습식용액으로 C. SVB는 에틸렌 발생을 억제하고 높은 수분균형 유지를 통해 갈변과 엽황화 발생을 낮추어 절화수명 및 품질에 효과적인 것으로 판단된다. The aims of the present study were to compare the quality of cut flowers of the lily (Lilium longiflorum) ‘Woori Tower’ when exported via dry transport (DT) and wet transport and to identify a wet shipping solution that would improve both the vase life and quality of the cut flowers. Cut ‘Woori Tower’ flowers were treated with tap water (TW), Chrysal AVB (C. AVB, 1 mL·L-1), Chrysal SVB (C. SVB, 1 pill·3 L-1), 1-methylcyclopropene kit (1-MCP, 2 mg·L-1), GA4+7 + BA (100 mL· L-1), Vital Oxide (V.O, 2 mL·L-1), or H2 water (HW, 1.5 mg·L-1) as DT and wet shipping solutions. First and second flowers were in full bloom during the consumer stage (Day 7), with no significant differences between treatment groups. For the third flowers, only the C. SVB and GA4+7 + BA treatment groups were in full bloom, and neither the control group nor the TW group had bloomed at all. The vase life of the C. SVB treatment group and the GA4+7 + BA treatment group were 9.5 and 9.0 d, respectively, which were longer by 1.8 to 2.3 d, and tilting, petal abscission, and yellowing occurred slightly less in these groups than in the DT group. In particular, the C. SVB treatment was associated with a higher fresh weight change rate and a longer positive water balance (9 d), which were effective for quality maintenance. Fewer bacteria were detected in the C. SVB treatment group than in the DT, TW, or wet shipping solution treatment groups, and the ethylene production of the C. SVB group was lower, thereby improving vase life and freshness. Therefore, wet shipping was more effective than DT in improving the quality of cut lily flowers. In addition, C. SVB was the most effective among the tested wet shipping solutions in improving vase life and flower quality, likely by inhibiting ethylene production and improving water balance.
