| Abstract:
Flower scent is a crucial strategy that plants use to attract pollinators and ensure plant reproductive success. Lilium regale Wilson is endemic to the southern part of China, with funnelform and especially fragrant flowers. To determine the scent characteristics of L. regale flowers, volatile compounds were trapped on Tenax GR adsorbent and analyzed by gas chromatography-mass spectrometry (GC/MS) using a direct thermal desorption method. The results showed that monoterpenoids and benzenoids dominated the floral scent. The important volatiles (>5%) in nocturnal emission were 1,8-cineole, methyl benzoate, and α-pinene, with smaller amounts (1-5%) of limonene, sabinene, linalool, β-pinene, (E)-β-ocimene, and 2-phenylethyl acetate. Floral volatiles showed a nocturnal maximum emission pattern, with higher volatile levels emitted during the night. | |
