황토와 숯을 이용하여 친환경적인 절화보존제를 개발하기 위해 본 실험을 수행하였다. 식물재료는 금어초 ‘Fujinoyuki’, 장미 ‘Red Corvette’, 그리고 카네이션 ‘Reina’의 절화를 사용하였다. 황토는 5, 10, 15, 그리고 20%, 숯은 1, 3, 5, 그리고 10% 농도의 용액을 만든 뒤 1시간 교반 한 후 여과지로 걸러서 절화보존용액으로 사용하였다. 절화수명 실험의 환경조건은 온도 22±2℃, 상대습도 50±10%, 그리고 광도 13.5μ㏖·m-2·S-1 PAR로 하였다. 보존용액에 황토와 숯을 첨가함으로써 3종 모두 대조구보다 절화의 수명이 크게 연장되었는데, 특히 금어초와 카네이션의 절화수명은 2배 정도 연장되었다. 금어초는 황토 15%구와 숯 1%구에서, 장미는 황토 15%구와 숯 10%구에서, 카네이션은 황토 10%구와 숯 3%구에서 가장 효과적이었다. 수분흡수량, 화폭 그리고 소화의 수는 절화의 수명이 길어질수록 비례하여 증가하였다. 황토 15% 또는 숯 5%가 첨가된 배지에서는 균의 증식이 거의 일어나지 않았다.

This experiment conducted in order to develop environment-friendly floral preservatives using loess and charcoal. Cut flowers of Antirrhinum majus ‘Fujinoyuki’, Rosa hybrida ‘Red Corvette’, and Dianthus caryophyllus ‘Reina’ were used as plant materials. Solutions at concentrations of 5%, 10%, 15% and 20% loess and 1%, 3%, 5% and 10% charcoal with stirring for an hour and leaching by using filter papers were used as holding solution. The experiment conditions were 22±2℃ in temperature, 50±10% in relative humidity, and 13.5 μ㏖·m-2·S-1 PAR in light intensity. By adding loess and charcoal into preservatives, the longevity of cut flowers was lengthened more than that of control. A solution of 15% loess and 1% charcoal in snapdragon, 15% loess and 10% charcoal in rose, and 10% loess and 3% charcoal in carnation were the most effective. Vase life in the cut flowers of snapdragon and carnation were prolonged by about two-fold. Amount of water uptake, the flower diameter, and the number of florets were increased in proportion with longer vase life of cut flowers. In order to observe the proliferation rate of bacteria in holding solution, cut flowers were incubated with or without 15% loess and 5% charcoal for a week. While the proliferation of bacteria was increased sharply in control, cut flowers added with loess and charcoal were scarcely changed.
