Abstract

This study was conducted to investigate the effect of vase material and floral preservative treatment over time on flower color, leaf color and flower size of cut flowers Rosa hybrida 'Aqua' and 'Corvernet', and Gerbera jamesonii 'Honeymoon' and 'Golden Time' stuck in a glass, porcelain, or onggi (pottery with a dark bronze glaze) vase containing either tap water or a floral preservative solution. The ${\Delta}E$ values in flower color of 'Aqua' rose at 8 days after treatment with a floral preservative in onggi and porcelain vases were low. The ${\Delta}E$ value of 'Covernet' rose treated with floral preservative in an onggi vase was the lowest and L value was the closest to that of petals of cut flowers at just before treatment (control). The ${\Delta}E$ value of 'Honeymoon' gerbera treated with a floral preservative in an onggi vase was the lowest and a value of 58.81 and b value of 34.29 were the closest to that of the control group as color of cut flowers in an onggi vase was similar to the color at the beginning of treatment. The ${\Delta}E$ value of 'Golden Time' gerbera treated in an onggi vase was significantly lower than that in a porcelain or glass vase and a value of -7.81 treated with a floral preservative solution in an onggi vase was the closest to the control and b value was high in an onggi vase as well. The L, a, and b values in leaf color of roses were similar to each value of the control and ${\Delta}E$ value of 3.25 measured in an onggi vase was lower than that in a porcelain or glass vase. Flower diameter of 'Covernet' and 'Golden Time' roses treated with a floral preservative in an onggi vase was greater than that in other treatments. From these results, the floral preservative applied to a holding solution is assumed to improve the quality and freshness of cut roses and gerberas by inhibiting microbes propagation and by promoting uptake of water and nutrients. The onggi vase with fine pores will promote the expression and maintenance of flower and leaf colors and may increase flower diameter by high air permeability.

본 연구는 화병의 재질과 절화보존제 처리 여부가 절화의 화색, 엽색, 그리고 화경에 미치는 영향을 구명하기 위해 조사하였다. 절화 장미 (Rosa hybrida) 'Aqua'와 'Corvernet' 및 거베라 (Gebera jamesonii) 'Honeymoon'과 'Golden Time'을 수돗물 또는 절화보존제 용액이 들어있는 유리, 자기 및 옹기 화병에 꽂고 화색, 엽색, 최대화경의 변화를 측정하였다. 처리 8일 후 화색에 있어서 장미 'Aqua'의 ${\Delta}E$값은 옹기와 자기화병의 보존제 처리에서 작게 나타났다. 장미 'Covernet'은 옹기화병의 보존제 처리에서 ${\Delta}E$값이 가장 작았고, L값도 처리 직전의 꽃잎 (대조구)과 가장 근접하였다. 거베라 'Honeymoon'의 경우 절화보존제 처리와 옹기화병에 의해 ${\Delta}E$값이 가장 작게 나타났고, a와 b값도 58.81, 34.29로 대조구와 가장 유사하였기 때문에 옹기화병에 꽂은 절화의 화색이 처리 직전의 화색과 유사하였다. 거베라 'Golden Time'의 ${\Delta}E$값은 옹기화병이 자기나 유리화병보다 크게 작았는데, a값은 옹기화병의 보존제 처리에서 -7.81로 가장 근접하였고, b값 역시 옹기화병에서 높게 나타났다. 장미의 엽색에 있어서는 옹기화병의 보존제 처리에서 L, a, b값이 처리 직전의 잎과 가까웠고 ${\Delta}E$값은 옹기화병에서 3.25로 나타나 자기나 유리에 비해 작았다. 화경은 장미 'Covernet'과 거베라 'Golden Time' 모두 옹기의 보존제 처리에서 크게 나타났다. 이상의 결과로 보존용액에 절화보존제를 첨가함으로써 미생물 번식을 감소시켜 절화수명이 연장되어 장미와 거베라의 품질 및 신선도를 증가시킬 수 있고, 다공질의 옹기 화병을 사용하여 통기성을 증가시키면 화색과 엽색을 좀 더 좋게 하고, 화경도 증가시킬 수 있을 것으로 판단된다.
