초록

본 연구목적은 아이리스 'Blue Magic' 절화의 수명연장, 절화 품질 향상 및 개화율을 촉진시키기 위하여 수행되었다. 절화 아이리스의 수명을 연장하기 위해 1-MCP는 250, 500, $750nL{\cdot}L^{-1}$로 처리하였다. 1-MCP 처리는 무처리구에 비해 개화소요일수가 1일 빨라졌으나 절화수명은 무처리구와 처리구간 큰 차이가 나타나지 않았다. 개화율은 대조구의 경우 64.2%에 비해 1-MCP 처리구 에서는 75% 또는 그 이상 이었다. 특히, $250nL{\cdot}L^{-1}$를 12시간 처리한 구에서는 모든 개체가 개화하였다. 화기로부터 에틸렌이 생성되는 것은 절화수명에 있어 가장 중요한 요인으로 간주되고 있다. Gas chromatography(GC)로 에틸렌 생성량을 측정한 결과 절화수명과 방출된 에틸렌 사이에는 직접적인 관련이 없었다. 무처리구와 비교하여 에틸렌 발생은 1-MCP의 농도가 증가할수록 다소 증가하는 것으로 나타났다. 1-MCP와 BA를 병행처리한 경우, 개화율이 촉진될 뿐만 아니라 절화수명도 연장되었다. 그러므로 아이리스 절화 수확 시 1-MCP를 처리하는 것은 미개화율을 억제함으로써 절화품질과 수명을 향상시킬 수 있다.

This research was aimed to extend the vase life, improve the cut flower quality and promote flowering rate of bulbous cut Iris 'Blue Magic'. Three different concentrations of 1-MCP ranging from 250 to $750nL{\cdot}L^{-1}$ were treated on cut Iris flowers for the vase life elongation. Several effects of 1-MCP treatment has shown such as early flowering as one day but vase life showed no significant differences comparing to the untreated control. Flowering rate was 75% or more in the treated ones as compare to 64.2% in untreated control. Especially, in a treatment with $250nL{\cdot}L^{-1}$ 1-MCP for 12 hours it showed all flowering. In many post-harvest experiments of cut flowers, ethylene production from flower organ has considered as most critical factor on vase life. Ethylene production from flower organ was measured by gas chromatography (GC) and it showed that there is no direct relation between flower longevity and emission of the ethylene gas in cut Iris. In comparison with the untreated control, ethylene generation rather seems to be increased as 1-MCP treatment increased. There was a synergy effect when 1-MCP and BA applied simultaneously in which flowering and vase life were fastened and also extended, respectively. Therefore, treatment of 1-MCP for cut Iris at flower early harvest is able to improve the flower quality both by diminishing non-flowering rate and by extended flower longevity.
