Abstract

We investigated the intensity and pattern of the scent produced by diploid and tetraploid Cymbidium flowers, using an electronic nose with 6 metal oxide sensors (MOS). The MOS responses were evaluated by principal component analysis, discriminant function analysis, and sensor data. These analyses revealed that tetraploid flowers had a stronger scent than diploid flowers in Cymbidium Golden Elf 'Sundust'. Furthermore, among the different flower parts-column, lip, and petals-the column produced the strongest scent. There was no significant difference between the flowering periods of diploid and tetraploid potted Cymbidium Golden Elf 'Sundust' and Cymbidium Elma 'Orient Toyo' grown in a greenhouse. Moreover, there were no significant differences between the number of flowers per flower stem and the length of flower stems on the diploid and tetraploid plants of these two Cymbidium cultivars. This study provides potentially useful information for the breeding of polyploidy Cymbidium in the floriculture industry.

배수성에 따른 심비디움 꽃 향기의 변화를 알아보기 위해 전자코를 이용하여 C. Golden Elf 'Sundust'의 2배체와 4배체 꽃을 PCA(주성분분석)와 DFA(판별함수분석)로 분석한 결과, 꽃 한 송이의 향기는 2배체에 비해 4배체에서 강하게 나타났고, 화기 조직별 향기는 예주가 가장 강하게 나타났으며 꽃잎과 설판은 근접한 패턴을 보였다. 배수성에 따른 심비디움의 분화수명의 차이를 알아보기 위해 C. Golden Elf 'Sundust'와 C. Elma 'Orient Toyo' 분화의 화경을 조사한 결과 개화기간뿐 만 아니라 화경당 화수, 화경장에서 모두 차이가 나타나지 않았다. 본 연구는 심비디움을 비롯한 다른 종류의 난과식물 배수체 육종에 있어 기초자료로 유용하게 활용 될 것이다.
