Abstract
Discrimination of lily fragrance was performed by the use of an electronic nose, Prometheus (Alpha-MOS, France) equipped with a metal oxide sensor (MOS) array and a finger-print mass spectrometer (FMS). Fragrance of some Oriental (O), Asiatic (A), Longiflorum (L) and their interspecifc hybrids were investigated. Principle component analysis of the raw signal data was carried out to show the differences among samples. The fragrance of the three lily groups, O, A and L was clearly discriminated by both MOS and FMS. Interspecific hybrids 'Otomenosugata' (L. x formolongi x L. rubellem) and KU2 (L. x folmolongi x 'Marco Polo') were also discriminated from their parents. E-nose has a great potential to discriminate lily fragrance and would be a useful tool for the fragrance breeding of ornamentals.
