Abstract

This experiment was conducted to examine the ideal condition for multiple colors dyeing of cut rose, 'Akito'. Four different colors of dye were applied to make multiple flower colors in cut rose by absorption method. Acidic condition around pH 3.5 showed the fastest absorption speed in all four colors. There is no difference at each pH levels, at part of leaves dyeing, it is more affected colors rather than pH levels in purple and blue colors. From vary concentration of each dyes, $10g{\cdot}L^{-1}$ concentration of dyeing solution gave the best color definition. But it's not significant and result was different by each color in a same concentration. 10 minutes of dyeing performed pastel color and 30 minutes performed the best color definition, but the 30 minutes treatment accompanied with significant dyeing on the leaves also. As a result of this experiment, optimum condition for dyeing cut rose, 'Akito' requires pH 3.5, $5-10g{\cdot}L^{-1}$ of dye concentration and 10-30 minutes treatment.

본 실험은 절화장미 'Akito' 품종을 재료로 하여 4가지 색상(yellow, orange, purple, blue)을 동시에 염색하기 위한 최적 조건을 구명하고자 수행하였다. 염료용액의 pH를 3.5에서 9.0으로 처리하였을 경우, pH 가 3.5에서 4가지색 모두 흡수속도가 빨랐다. 꽃의 착색에서는 각 pH별 차이가 없었고 잎에서는 pH의 차이보다는 색상의 차이에 따라 purple과 blue에서 색 발현이 현저하였다. 염료 별 농도처리에서 $10g{\cdot}L^{-1}$ 농도에서 가장 선명한 색 발현이 되었으나 유의성은 없었고 염색의 종류에 따라 유의차를 보였다. 염색에 미치는 처리시간은 10분 후에 파스텔 색상이 발현되었고, 30분 후에는 꽃의 색상이 가장 선명하였지만 동시에 잎에서도 착색이 진행되었다. 이상의 결과로부터 절화 장미 'Akito'의 염색 시 pH 3.5, 염색농도 $5-10g{\cdot}L^{-1}$, 처리시간 10-30분간 처리가 화색의 발현 및 품질의 완성도를 높이는데 적당하였다.
