Abstract

This research was conducted to figure out the effect of 1-methylcyclopropene, one of inhibitors of ethylene on the vase life of cut alstroemeria 'Alpine', snapdragon 'Fuji no Yuki', dahlia 'Toast, and lily 'Georgia'. Four kinds of cut flowers were treated with 250, 500, and 750 ppb of 1-MCP respectively for 12 hours. In case of cut alstroemeria, no significant difference was found between the untreated control and the treated ones in the days to flowering. The vase life in the treated ones, however, was extended for over two days, and the treated one with 250 ppb had the longest record with 17.1 days. In every treated ones of cut snapdragon, the remaining florets was more than that of the untreated control. The vase life showed, however, no difference. With the 1-MCP treatment, the vase life of cut dahlia was longer about two days than that of the untreated control. However, water uptake showed the opposite result. The vase life of cut lily showed no significant differences in all treatments. In case of water absorption, the treated one with 750 ppb uptaken more water by 3 ml.

본 연구는 에틸렌 작용 억제제 중 하나인 1-methylcyclopropene(MCP)이 알스트로메리아, 금어초, 다알리아 및 나리의 절화수명에 미치는 영향을 알아보기 위하여 실시하였다. 4종의 절화에 1-MCP 250, 500, 750 ppb를 각각 12시간 처리하였다. 알스트로메리아의 경우 개화소요일수는 대조구와 1-MCP 모든 처리구에서 유의차가 없었다. 절화수명은 대조구보다 처리구에서 2일 이상 연장되었으며, 250 ppb 처리구가 17.1일로 가장 길었다. 금어초는 잔여소화율이 대조구와 비교하여 1-MCP 모든 처리구에서 높아졌다. 그러나 절화수명은 대조구와 처리구 사이에 유의차가 없었다. 다알리아의 절화수명은 1-MCP 처리시 대조구보다 2일 정도 연장되었다. 수분흡수량은 절화수명과 반대 양상을 나타내었다. 나리의 절화수명은 대조구 12.6일과 비교하여 모든 처리구간 유의차가 없었다. 수분흡수량의 경우 대조구와 비교할 때 1-MCP 750 ppb 처리구에서 약 3 mL 더 많았다.
