Abstract
본 연구는 이끼의 추출물을 이용하여 절화장미 'Enjoy'의 수명을 효과적으로 연장시킬 수 있는 천연 절화수명 연장제를 개발하기 위하여 수행하였다. 이끼 추출물중 R. hybrida 'Enjoy'의 절화수명 연장에 가장 효과적이었던 Hypnum jutlandicum 2 $mg{\cdot}L^{-1}$에 sucrose 0, 1, 3, 5%를 첨가한 후 sucrose가 R. hybrida 'Enjoy'의 수명에 미치는 영향을 분석하였다. 연구의 결과, sucrose를 H. jutlandicum 추출물과 함께 사용할 경우에는 R. hybrida 'Enjoy'의 잎이 엽록소를 상실하여 탈색되고 위조현상이 발생하며, 오히려 절화의 수명이 단축되는 것으로 나타났다. 그러나 H. jutlandicum 추출물과 HQS를 함께 사용하는 것은 R. hybrida 'Enjoy'의 수명을 증가시키는 것으로 나타났으며, 특히 HQS를 100 $mg{\cdot}L^{-1}$ 농도로 첨가했을 때 R. hybrida 'Enjoy'의 수명연장 효과가 가장 증가하는 것으로 나타났다. H. jutlandicum 추출물 2 $mg{\cdot}L^{-1}$ 첨가구의 pH를 조절하지 않거나(pH 3.8), pH 3.0, 4.0, 5.0로 조절하여 R. hybrida 'Enjoy'의 절화수명에 미치는 영향을 분석한 결과, pH를 조절하지 않은 pH 3.8인 보존용액을 사용하는 것이 R. hybrida 'Enjoy'의 수명이 오래감을 알 수 있었다. 이상의 연구 결과, H. jutlandicum 추출물(2 $mg{\cdot}L^{-1}$)에 HQS(100 $mg{\cdot}L^{-1}$)를 첨가한 보존용액이 R. hybrida 'Enjoy'의 절화수명을 연장시켰으며, 이끼는 주변에서 쉽게 구할 수 있어 환경오염의 피해가 없으며 천연 보존제로서 개발가치가 있을 것으로 기대된다. This study was performed to develop a natural preservative which had the most successful effect on prolonging the vase life of cut flowers Rosa hybrida 'Enjoy'. To determine the effect of sucrose on vase life of cut roses, R. hybrida 'Enjoy', 0, 1, 3 or 5% of sucrose was mixed with Hypnum jutlandicum extract. The result showed that in the case of adding sucrose to extracts from H. jutlandicum, vase life of cut flowers was shortened, along with the cut flowers losing chlorophyll, becoming decolorized and finally showing wilting phenomenon. However, using hydroxy quinoline sulfate (HQS) and extracts from H. jutlandicum together exhibited an improved effect of prolonging vase life, especially when adding 100 $mg{\cdot}L^{-1}$ HQS, which had the effect of prolonging the vase life of R. hybrida 'Enjoy' the most. Regarding pH of extracts, 2 $mg{\cdot}L^{-1}$ of extracts from H. jutlandicum show originally pH 3.8. This was compared with adjusted extract solutions as pH 3.0, 4.0 or 5.0. The results showed that the solution of pH 3.8 had the most successful effect on prolonging the vase life of R. hybrida 'Enjoy'. Given all the results, H. jutlandicum extract (2 $mg{\cdot}L^{-1}$) and HQS (100 $mg{\cdot}L^{-1}$) was the most effective in prolonging the vase life of cut R. hybrida 'Enjoy'. Moss is expected to be worth developing as a natural preservative since it is easy to get and causes no damage to the environment.
