    • Cymbidium is the most important crop in the Orchidaceae family. There are several beautiful and colorful Cymbidium species flowers. Among them a few species of Cymbidium have a floral scent and flavor. Headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS) was used to identify the floral scent of the different floral organs of Cymbidium cultivar ‘Sunny Bell’ for the evaluation of floral volatile polymorphism as a basis to determine the best time of harvest. Electronic nose analysis results, coupled with discriminant factor analysis, suggested that emitted odors varied in different Cymbidium cultivar ‘Sunny Bell’ floral organs, including the column, labellum, sepals, and petals. The first two discriminant factors explained 99.193 % of total system variance. The major floral scent were α-pinene, octamethylcyclotetrasiloxane, β-myrcene, 2,6-dimethlnonane, eucalyptol, trans-β-ocimene, 4,8-dimethyl-1,3,7-nonatriene, linalool, and decamethylcyclopentasiloxane. Moreover, in a principal component analysis, sepals and petals were located closely on the score plot.
