몇몇 절화수명제(Citric Acid, Sucrose) 처리에 따른 절화 장미의 화색 변화 Effect on the flower color of cut rose (cv. 'Red Sandra') with treatment of citric acid and sucrose원문보기
乾燥花는 花色이 脫色 (color fading) 또는 變色 (discoloration) 되어 花色을 오랫동안 유지하지 못하는 단점이 있다. 이러한 문제점 해결을 위해 변색 정도가 심한 薔薇(Rose)를 가지고 원래의 색으로 復原시키는 방법을 硏究코자 하였다. 본 實驗은 CA, Sucrose 溶液을 단용 또는 混用處理로 병행하여 처리한 후 測色計로 측정, 꽃잎의 pH 濃度, ...

Anthocyanin 色素 추출 후 OD 측정 결과 산 처리(pH5), 糖 처리 (Sucrose 6%) 구인 단용구에서 生花와 乾燥花 사이에 吸光度 차이가 적어 乾燥시 변색된 花色復元 효과와 關聯性이 있었다. 따라서 일반적으로 開花 후 일수가 경과하면 花辯의 生長과 色素 생성이 정지하고 노화에 의한 退色이 급격히 전개된다. 단백질 분해에 의해 pH가 상승하고 Anthocyain을 분해해 退色이 일어나는데 糖의 첨가나 pH를 낮추므로 花의 노화를 억제하고 간접적으로 退色을 방지하여 花色變化를 줄일 수 있었다.

It was hard to preserve the original flower color in the way of drying because the color of dried flowers were easily faded out or discolored. This study was carried out to determine the effect of treatment with citric acid and sugar on restoration of the flower color in the dried flowers of rose. The Hunter color values, pH in petal, flower size and optical density after treated with citric acid and sugar in single or combination were determinated. Hunter color values(L, a and b) of treatment with citric acid( pH4, 5) was higher other treatments. Especially, the flower color was restored effectively by treating with citric acid( pH 5) and sucrose(6%). Also Acidic solution treatment was prolonged the life span of cut flower in the basis of result that the degree of flowering was delayed by that treatment. However strong acid solution(pH 1-3) caused the yellowing of petal and vent neck of flower. It is shown that treatment of citric acid and sucrose also affected the pH change and restoration .of flower color in dried flower. Optical density of anthocyanin extracted from rose flowers was examined. As a result, the treatment of citric acid(pH5) and sucrose(6%), respectively showed no difference in absorbance between fresh flower and dried flower. It indicated that acid or sugar treatment had an effect on restoration of flower color discolored during drying. Generally, as the time went after flowering, the growth of petal and pigment production stopped and discoloration was developed rapidly in aging. It is known that this resulted from increase of pH caused by degradation of proteins and degradation of anthocyanin. It is considered that addition of sugar or lowering pH with acid made aging of flower delayed and prevented from discoloring to reduce the change of flower color indirectly.
