Floral scent composition of nine Oriental × Trumpet hybrid lilies

Lily is one of the most important ornamental crops in the world. OT (Oriental × Trumpet) hybrids have showy flowers and strong scents. We collected floral volatiles by headspace adsorption during the night (21:00-23:00) and analyzed them by gas chromatography-mass spectrometry using direct thermal desorption. The results demonstrated that monoterpenoids and benzenoids dominated the floral scents. The major scent compounds were 1,8-cineole, (E)-β-ocimene, methyl benzoate, and linalool. α-Pinene, sabinene, β-pinene, myrcene, and limonene were emitted as minor compounds. It is speculated that these scented OT hybrids may have inherited their floral scents from both parents.
