“…This compound has been found in over 50% of plant families [8], and in freesia, the importance of linalool in the aroma of this species has been reported [37]. Previous studies concluded that based on the stable inheritance of linalool emission and the higher amount compared to other VOCs in the bouquet, linalool may have an important influence on the aroma of freesias [38]. The purpose of the production of linalool is not clear, but it might be to attract insects, or be related to a defense mechanism since linalool is relatively toxic to animals and microorganisms [39].…”

Floral Scent Evaluation of Three Cut Flowers Through Sensorial and Gas Chromatography Analysis

The main function of floral scent is to attract and guide pollinators, but it is also an important character in the ornamental plant industry. Several studies have considered the chemical evaluation of floral scent during vase life, but only a few have considered sensorial analysis of this character, which is a very important quality trait for the marketing of ornamental plants. This study focused on assessing the floral scent of three fragrant cut flowers of high economic importance: Lilium, chrysanthemum, and freesia. Eighty individuals were included in a sensorial analysis where the attributes of floral scent liking and intensity were evaluated. The composition of the floral scent was analyzed through the collection of headspace followed by gas chromatography-mass spectrometry (GC-MS). The floral scents of oriental lily and freesia were perceived as more intense, compared to chrysanthemum. A total of 28 volatile compounds were detected and the monoterpenes β-pinene (40.7 ± 1.8 μg·L−1), β-cis-ocimene (5552 ± 990 μg·L−1), and linalool (11,800 ± 220 μg·L−1) were the major volatile organic compounds (VOCs) present in chrysanthemum, lilium, and freesia, respectively. The results presented in this study confirm that the concentration and abundance of volatile compounds is not directly related to the human perception of floral scent.

“…This complexity might be due to the heterozygosity of ornamental carnations and/or heterosis. In hybrids between Freesia refracta and F. hybrida, the complex inheritance pattern of flower scent was also pointed out to be possibly involved in the heterozygosity of the parents (Fu et al, 2007). In Cyclamen hybrids, it is suggest that each emission level of some floral scent compounds is affected by the amount of the genome (gene) derived from its parents (Ishizaka et al, 2002).…”

Most modern carnation (Dianthus caryophyllus L.) cultivars have weak fragrances dominated by the scent of methyl benzoate. Wild Dianthus species with strong or unique scents may be useful gene resources for the improvement of carnation fragrances. We investigated the scents of interspecific hybrids between carnations and fragrant wild species by gas chromatography-mass spectrometry (GC-MS), and evaluated the usefulness of wild species for fragrant breeding in carnations. Dianthus hungaricus, which produced large amounts of various benzenoids, was crossed with a carnation with a floral scent dominated by methyl benzoate, but benzenoid diversity was not increased in the interspecific hybrid. We also analyzed some existing interspecific hybrids. Dianthus superbus var. longicalycinus had high amounts of β-ocimene and β-caryophyllene. These terpenoids were acquired as principal scent compounds by some interspecific hybrids between this species and a carnation lacking terpenoids. Three unidentified wild species (Dianthus sp. 4, 5, and 6) emitted high amounts of benzenoids, including eugenol, benzyl alcohol, methyl o-anisate, and methyl salicylate. These benzenoids were also detected in interspecific hybrids between carnations and the wild species, and the amounts were increased compared to the parental carnation. The emission of these scent compounds of wild Dianthus species was inherited by most hybrids lines; the variety and amounts of scent compounds tended to increase compared to parental carnations, although there was no general hereditary pattern. As we actually sensed the fragrances of the principal compounds from some hybrid flowers, the usefulness of interspecific hybridizations for the improvement of flower fragrances was confirmed. Dianthus superbus var. longicalycinus and Dianthus sp. 4, 5, and 6 seemed promising resources regarding the addition of terpenoids and the increase in benzenoid variation in the floral volatiles of carnations.

“…The intersection LA hybrids are good examples of scent modification by interspecific hybridization, and a few other ornamentals' scent traits have been improved by genetic modification (Zuker et al, 2002;Zvi et al, 2012). However, owing to the heterozygosity of the parents and various genes involved in the production of scent compounds (Andargie et al, 2014;Fu et al, 2007;Kishimoto et al, 2013;Spiller et al, 2010), the modification of fragrance is not easy. In the future, combining conventional breeding with molecular breeding techniques would help develop novel lily cultivars with more pleasant floral fragrances.…”

Lilium cultivars have a wide range of variation in floral scent phenotypes. Using gas chromatography–mass spectrometry (GC/MS) analyses of volatile emissions during the night, the floral scent compositions of 35 lily cultivars from seven different hybrid groups were studied. The results showed that there was a positive correlation between volatile emission levels and scent intensities. Nonscented lily cultivars belonging to Asiatic hybrids hardly emitted volatiles, light-scented Longiflorum × Asiatic hybrids emitted low levels of volatiles, and scented lily cultivars (belonging to Oriental, Trumpet, Longiflorum, Longiflorum × Oriental, and Oriental × Trumpet hybrids) emitted significantly high levels of volatiles. In general, the scent compositions of lily cultivars were similar within the same hybrid group, and the differences among hybrid groups reflect their pedigree. Monoterpenoids and benzenoids dominated the floral scents of most volatile-emitting lily cultivars, whereas monoterpenoids alone dominated the floral scents of some volatile-emitting lilies. Although various scent compounds were released from volatile-emitting lily cultivars, the dominant scent compounds were focused on three monoterpenoids [1.8-cineole, linalool, and (E)-β-ocimene] and one benzenoid (methyl benzoate). The scent traits of lily cultivars could be traced back to their parents.
