Abstract

This study was carried out to investigate conveyance environment during shipping export to Japan and the optimum pre-treatment of cut Dendranthema grandiflorum 'Baekma'. Shipping from Korea to Japan, which usually takes three to five days, requires keeping the flower at the ideal temperature. When inspection took place in Japan, the ideal temperature was lost and deterioration began. Once the ideal temperature is lost, deterioration takes place. The results of this work showed that vase life was extended by treatment Chrysal RVB and NaOCl compared to the control (distilled water), and Chrysal RVB was used to maintain the flower from bud to full bloom. Bacterial growth was not observed after pretreatment with NaOCl or $ClO_2$. However, $ClO_2$ pre-treatment was observed to affect the early growth period of the bacteria. The chlorophyll content was the highest after Chrysal RVB or NaOCl pretreatment compared to the other treatments. Therefore, these results support pretreatment with NaOCl and Chrysal RVB of Dendranthema grandiflorum 'Baekma' for export to Japan.

본 연구는 절화 국화 'Baekma'를 일본으로 선박 수출 시 수송 환경을 분석하였으며, 절화 국화의 선도를 유지하기 위한 최적 전처리제를 구명하고자 하였다. 그 결과 일본으로 절화 국화를 수출시 약 3일~5일이 소요되었으며, 국내 이동, 선박 운송 및 일본 내에서 이동은 저온이 유지되었으나, 일본에서 검역시 상온에 노출되는 것으로 조사되었다. 이는 품질의 손상을 야기하는 것으로 수송 전체 기간동안 저온조건을 유지해야 할 것으로 판단되었다. 또한, 전처리제는 Chrysal RVB, NaOCl 처리구가 절화수명 연장에 효과적이었으며, Chrysal RVB 전처리는 절화 국화가 끝까지 만개하여 화형이 유지되었다. 박테리아 검정 결과 NaOCl, $ClO_2$ 처리구의 박테리아가 검출되지 않아 살균 성분이 세균증식을 막아준 것으로 판단되었다. 그러나 $ClO_2$처리구는 수확 후 초기 생육에 영향을 미치는 것으로 사료되었다. Chrysal RVB 처리 및 NaOCl 처리구의 엽록소 함유량이 가장 높은 것으로 조사되었다.
