Abstract

Our study evaluated the effect of pretreatment and shipping solution on the quality of the Lilium OT hybrid ‘Zambesi’, which is harvested in South Korea and exported to Japan. We found that vase life was prolonged by approximately 1-2 days when pretreatment or shipping solution was applied. Moreover, both tap water pretreatment followed by shipping using Chrysal AVB and Chrysal SVB pretreatment followed by shipping using tap water + 1-MCP produced less browning and wilting. The change in flower diameter was very small (0.06 cm) when pretreatment with Chrysal SVB was followed by shipping using tap water + 1-MCP. On the auction stage, the flower diameter increased slightly and then slowly decreased. The rate of fresh weight change, after pretreatment with Chrysal SVB and shipping using tap water + 1-MCP, was slightly higher than that of the other treatments. For water uptake, the result was similar. For water balance, which is affected by fresh weight and water uptake, Chrysal SVB followed by shipping using tap water + 1-MCP showed a two-day delay in obtaining a negative value, compared to the other treatments. Also, water balance was greater in flowers pretreated with Chrysal SVB and shipped using Chrysal AVB; these flowers exhibited the longest vase life. The rate of stomatal size change according to brightness, using Chrysal SVB followed by either shipping with tap water + 1-MCP or Chrysal AVB, was slightly higher than the other treatments; this result was similar to that for water balance. Therefore, the vase life of cut lily was longer when only one pretreatment or shipping solution was applied. For pretreatment, Chrysal SVB was more effective than tap water. For shipping solution, tap water + 1-MCP or Chrysal AVB effectively extended vase life and maintained quality.

본 연구는 수출용 절화 백합 Lilium OT hybrids ‘Zambesi’의 일본 수출 과정을 모의 수송 환경으로 적용하여 전처리(pretreatment)와 수송 시 건식 처리 및 습식용액(shipping wet solution) 처리에 따른 절화 백합의 품질을 비교 분석하고자 연구를 수행하였다. 절화수명을 조사한 결과, 전처리와 수송 시 습식용액 중 한 처리만 하여도 수명이 약 1-2일 정도 연장되는 것으로 나타났다. 그러나 특히 노화 양상에서 tap water 처리 후 습식용액 Chrysal AVB로 수송한 처리구와 Chrysal SVB 처리 후 습식용액 tap water + 1-MCP로 수송한 처리구가 갈변, 위조의 노화 양상이 적게 나타났다. 화폭의 경우, 경매장 시점인 실험 1일에 Chrysal SVB 처리 후 습식용액 tap water + 1-MCP로 수송한 처리구가 0.06cm로 가장 개화가 덜 된 상태를 유지하였으며, 소비자 단계에서는 다소 화폭이 증가하다가 완만하게 감소하였다. 생체중 변화율을 조사한 결과, Chrysal SVB 처리 후 습식용액 tap water + 1-MCP로 수송한 처리구가 다른 처리구에 비해 높게 유지되었으며, 수분 흡수량도 많은 것으로 조사되었다. 수분균형 조사 결과, Chrysal SVB 처리 후 습식용액 tap water + 1-MCP로 수송한 처리구는 다른 처리구에 비해 약 2일 정도 늦게 ‘–’ 값으로 떨어지는 것으로 나타났다. 또한, 절화수명 연장에 효과적이었던 Chrysal SVB 처리 후 습식용액 Chrysal AVB 로 수송한 처리구의 수분균형이 다른 처리구에 비해 높은 것으로 나타났다. 명·암에 따른 기공 크기 변화율 조사 결과, Chrysal SVB 처리 후 습식용액 tap water + 1-MCP로 수송한 처리구와 Chrysal SVB 처리 후 습식용액 Chrysal AVB로 수송한 처리구가 다른 처리구들과 유의한 차이를 보였으며, 수분균형과 비슷한 결과였다. 따라서, 절화 백합 ‘Zambesi’는 전처리와 수송 시 습식용액 중 하나만 처리하여도 절화수명이 연장되는 것으로 나타났으며, 특히 전처리는 tap water 처리보다 Chrysal SVB 처리, 수송 시 습식용액은 tap water + 1-MCP 또는 Chrysal AVB 처리가 절화수명 연장 및 품질 유지에 우수한 것으로 판단된다.
