Abstract:

HS-SPME/GC-MS was used to analyze the floral components of different cultivars, different flowering stages and different parts of flower organs in Cymbidium hybrid. The results showed that the main components in Cymbidium hybrid were terpenoids. The difference in floral aroma release between different cultivars was obvious. The main components of ‘K24’ are 1,8-Cineole (23.91%) and 1-Hexanol (13.74%). The main components of ‘K21- 1’ are (E)-Nerolidol (30.39%) and Cyclohexane (22.99%). The main components of ‘Hongmeiren’ are α-Farnesene (43.50%) and Linalool (34.52%). The main components of ‘K18’ are β-Caryophyllene (43.57%) and α-Bergamotene (19.59%). The main components of ‘Shibagege’ are β-Caryophyllene (42.99%) and α-Farnesene (19.65%), and the main components of ‘Hanchenggongzhu’ are β-Caryophyllene (52.40%) and α-Farnesene (9.99%). The component number and released amount of ‘K18’was highest in full opening stage. The main components of petals and sepals are β-Caryophyllene, and the main components of lips are β-Caryophyllene from different parts of the floral organ.
