초록

상온에서 기체로 존재하는 기존의 에틸렌 작용억제제인 1-MCP와 달리 상온에서 액상으로 존재하여 분무살포가 가능한 에틸렌 작용억제제를 개발할 목적으로 cyclopropene 유도체의 하나로서 2-decylcyclopropene-1-carboxylic acid ethyl ester(DCPE)를 합성하여 부유 단감을 대상으로 그 처리효과를 분석하였다. $4{\cdot}10^{-4}$ M의 DCPE를 수확 전에 분무살포 처리한 단감을 수확하여 45일간 저온저장한 후 상온($20^{\circ}C$)에 1주간 방치하면서 성숙 관련 지표의 변화를 조사한 결과, 에틸렌의 작용에 의해 유발되는 과육 연화의 진행이 효과적으로 지연되었으며, 그 억제 효과는 1 ppm의 1-MCP 처리와 대등한 수준이었다. 또한 DCPE는 적어도 한달간 성분 손실 없이 냉장 보관이 가능하였다. 따라서 DCPE는 단감 과실의 수확 후 과육의 연화를 지연시키는 약제로의 활용이 가능할 것으로 기대된다.
