Abstract

This study investigated the effects of various pretreatments, and the movable eco-friendly flower incubator (MEFI) system, on the quality of the cut spray-type Rosa hybrida L. ‘Lovely Lydia’ during export. Cut roses were pretreated with either 2 mL·L-1 ClO2 (Vital Oxide) or tap water (control) for 4 hours, and then held under a light-emitting diode (LED) emitting blue + ultraviolet (UV) light (i.e., the MEFI system) in cardboard boxes to simulate export. The vase life of roses treated with Vital Oxide + MEFI was longer (12.2 days) than the control. Flower diameter, fresh weight, and water uptake of roses were increased by tap water + MEFI and Vital Oxide + MEFI treatments, compared to control flowers. The Vital Oxide + MEFI treatment was more effective in maintaining postharvest quality than tap water + MEFI. Application of the MEFI system following pretreatment with 2 mL·L-1 Vital Oxide effectively improved the vase life and postharvest freshness of cut roses. This study demonstrated that ClO2, blue LED and the UV used in the MEFI system inhibited bacterial contamination throughout vase life, and consequently improved the quality of the cut rose ‘Lovely Lydia’.

본 연구는 수출용 스프레이 타입의 절화 장미 ‘Lovely Lydia’의 전처리 및 모의 수송 시 MEFI(movable eco-friendly flower incubator) 기술을 적용하여 품질에 미치는 효과를 알아보고자 수행하였다. 전처리는 수돗물을 대조구로 하여 Vital Oxide 2mL·L-1를 사용하였으며, 청색파장의 LED와 UV등을 수출 박스에 부착하여 MEFI 기술을 적용하였다. 모의 수송 후 품질 조사 결과, Vital Oxide로 전처리한 후 MEFI 기술을 적용한 처리구의 절화수명은 약 12.2일로 대조구보다 약 3일 정도 연장되었으며, 수돗물을 처리한 후 MEFI 기술을 적용한 처리구와 Vital Oxide로 전처리한 후 MEFI 기술을 적용한 처리구의 화폭 변화율, 생체중 변화율, 수분흡수량은 대조구보다 큰 것으로 조사되었다. 이 중 Vital Oxide로 전처리한 후 MEFI 기술을 적용한 처리구가 수돗물을 처리한 후 MEFI 기술을 적용한 처리구보다 박테리아 검정 결과 다소 적게 검출되어 선도 및 품질 유지에 더 효과적인 것으로 조사되었다. 따라서, Vital Oxide 2mL·L-1 전처리 후 MEFI 기술 적용 처리가 절화수명 및 선도유지에 효과적인 것으로 판단되며, 이는 ClO2 성분인 Vital Oxide 살균 효과와 MEFI 기술의 UV 살균효과, 청색파장 LED가 개화 유도 및 품질향상에 영향을 미친 것으로 판단된다.
