Abstract

The 1-methylcyclopropene (1-MCP) is the gaseous ethylene action inhibitor, which delay senescence and wilting by blocking the binding of its receptors. We investigated the effects of 1-MCP with different treated duration (0h (Control), 1h, and 4h) in cut flowers of Eustoma grandiflorum 'Voyage' and Cymbidium 'Lapine Hat'. The relative water uptake increased by 14.5% than control (9.8%) and the flower diameter maintained high from 3 to 11 days in 1-MCP treatment for 4h in E. grandiflorum 'Voyage'. The relative fresh weight was averagely high in 1-MCP treatment for 4h, however, the vase life was not significantly different in both cut flowers. Since the effects of 1-MCP treatment was differently responded by plant species and cultivars, interacted studies of duration and levels of 1-MCP are needed for the pronounced effects of postharvest quality.

에틸렌 활성 저해제인 1-methylcyclopropene(1-MCP)는 기체 물질로 에틸렌의 수용체 결합을 막아 노화 및 위조를 지연시킨다. 본 연구에서는 리시안셔스 'Voyage'와 심비디움 'Lapine Hat'에 다양한 1-MCP 전처리 기간(0시간(대조구), 1시간, 4시간)을 두어 수확 후 품질을 조사하였다. 리시안셔스 'Voyage'에서 1-MCP 4시간 처리 시 수분 흡수율은 14.5%로 대조구(9.8%)에 비하여 높았으며, 화폭은 3-11일 동안 가장 길게 유지되었다. 두 품종 모두 절화 수명은 1-MCP 처리 시간의 영향을 받지 않았다. 1-MCP 처리는 절화의 종류와 품종에 따라 미치는 영향이 상이하였으며, 전처리 효과를 극대화하기 위해서는 처리 기간과 농도의 복합 연구가 더욱 요구된다.
