보존용액 처리 반응에 따른 절화용 심비디움 품종 선발 = Selection of Cymbidium cultivars suitable for cut flowers due to changes by preservatives

다국어 초록 (Multilingual Abstract)

This study was conducted to select a Cymbidium pot plant cultivar suitable for cut flowers, and Cymbidium ‘Lovely Smile’ was considered to be the most suitable when determined by the changes in cut flowers characteristics. In the case of Cymbidium ‘Lovely Smile’, the relative water uptake showed the highest level of 93.1-94.4% after 3 weeks of treatment of preservatives for cut flowers, the relative fresh weight the lowest of 89.3-90.7%, and the dropped flowers was rarely seen until 5 weeks after treatment of preservatives for cut flowers. Cymbidium ‘Lovely King’ had a high relative water uptake rate and a relatively small decrease in the relative fresh weight, but the dropped flowers increased in all treatments after 5 weeks of treatment of preservatives for cut flowers. Cymbidium ‘Happy Day’ showed a significantly decreased relative water uptake rate and relative fresh weight compared to other cutivars, and dropped flowers started three weeks after the treatment of preservatives for cut flowers and increased to 12.8-15.3 in all treatments after five weeks. Cymbidium ‘Happy Day’ was judged to have greater changes in cut flower characteristics due to its heavy fresh weight and thick stem. Different patterns of color change during the senescence of Cymbidium cutivars were observed, and it was judged that it was necessary to understand the characteristics of each cultivar in order to determine a more accurate senescence progression stage. In the case of the three Cymbidium cutivars, there was no significant difference in the treatment of preservatives for cut flowers, but it could be estimated that the cut life of Cymbidium was long, so the effect of preservatives for cut flowers was less.

본 연구는 절화에 적합한 분화용 심비디움 품종을 선발하고자 수행되었는데, 심비디움 ‘Lovely Smile’이 절화 특성 변화로 판단했을 때 가장 적합한 것으로 사료되었다. 심비디움 ‘Lovely Smile’의 경우 절화보존용액 처리 3주 후 상대적 수분흡수율이 93.1~94.4%로 가장 높게 유지되었고, 상대적 생체중도 89.3~90.7%로 감소율이 가장 적었으며, 낙화율도 절화보존용액 처리 5주 후까지도 거의 보이지 않았다. 심비디움 ‘Lovely King’은 상대적 수분흡수율이 높고 상대적 생체중의 감소도 적었으나, 절화보존용액 처리 5주 후부터 낙화율이 모든 처리구에서 증가하였다. 심비디움 ‘Happy Day’는 상대적 수분흡수율과 상대적 생체중이 다른 품종들에 비해 두드러지게 감소하였고, 낙화도 절화보존용액 처리 3주 후부터 시작되어 5주 후에는 모든 처리구에서 12.8~15.3개로 증가하였다. 심비디움 ‘Happy Day’는 생체중이 무겁고 줄기가 굵어서 절화 특성 변화들이 더 컸던 것으로 판단되었다. 심비디움 품종별 노화에 따른 화색의 변화 양상은 다르게 관찰되었는데, 보다 정확한 노화 진행 단계를 결정하기 위해 품종별 특성들을 잘 파악할 필요가 있는 것으로 판단되었다. 세 품종의 경우 절화보존용액 처리에 따른 유의적인 차이는 보여지지 않았는데, 심비디움의 절화수명이 긴 편이여서 절화보존용액에 의한 영향이 더 적었을 것으로 추정되었다.
