Abstract

This study was conducted to investigate the effects of pretreatment and shipping temperature on leaf chlorosis in cut Lilium Oriental hybrid ‘Siberia’. Cut lilies were shipped under various temperatures (5, 10, 15, 25°C) for 5 days. When cut lilies were shipped at 25°C, leaf chlorosis was accelerated. However, chlorosis was significantly decreased by shipping at 5 to 15°C. In addition, leaf chlorosis was significantly decreased when the cut lilies were pretreated with a solution containing Promalin (BA + GA4+7) as compared to the control. Promalin completely prevented postharvest leaf chlorosis, whereas GA3 and Chrysal SVB were ineffective. Leaf chlorosis decreased more with Promalin dip treatment than with spray treatment. This pretreatment solution also extended the vase life of cut lilies. When cut lilies were pretreated with Promalin, yield (Fv/Fm) of chlorophyll fluorescence was highly maintained. Especially chlorophyll content was significant increased by Promalin treatment. Thus, shipping between 5 and 15°C and Promalin dip pretreatment significantly decreased leaf chlorosis in cut ‘Siberia’ lilies.

본 연구는 오리엔탈 나리 절화 ‘Siberia’의 잎 황화에 대한 수송온도와 전처리의 효과를 알아보고자 수행하였다. 나리 절화는 5, 10, 15, 25°C에서 5일 동안 수송하였다. 25°C로 수송 시 잎 황화가 심하게 일어났지만 5°C에서 15°C로 수송 시에는 잎 황화가 크게 감소하였다. Promalin(BA + GA4+7) 전처리는 무처리와 비교해 잎 황화를 크게 감소시켰다. Promalin 처리는 수확 후 잎 황화를 완벽하게 예방하였지만 GA3와 Chrysal SVB 처리는 효과적이지 못했다. 잎 황화는 Promalin 분무처리보다 침지처리 시 더 감소되었다. 그리고 Promalin 처리는 나리의 절화 수명을 연장하였다. Promalin 전처리 시 엽록소 형광반응의 최대광량자수율값이 높게 유지되었으며, 특히 엽록소 함량이 크게 증가하였다. 따라서 나리 절화 ‘Siberia’는 5°C에서 15°C로 수송하였을 때와 Promalin 침지 전처리 시 잎 황화를 크게 경감하였다.
