“…Methyl salicylate was the second most abundant volatile in 10W02-1 and exceeded the levels detected in the parental lines by 760-and twofold, respectively (Table 4), which explained its winter green-like minty scent (Burdock, 2010). This result is remarkable since methyl salicylate has not been reported previously as a major scent compound of carnation (Clery et al, 1999;Hudak and Thompson, 1997;Schade et al, 2001;Zuker et al, 2002). On the other hand, isoeugenol and methyl isoeugenol, principal volatiles in Dianthus sp.…”

“…Their scents are composed of benzenoids, terpenoids, fatty acid derivatives, and other minor components (Clery et al, 1999;Hudak and Thompson, 1997;Schade et al, 2001;Zuker et al, 2002). Classical fragrant carnations possess a spicy and clove-like odor caused mainly by benzenoids (Clery et al, 1999); however, in most modern carnations, scent variety and intensity have been lost, and methyl benzoate has become the dominant scent component (Clery et al, 1999). Therefore, the commercial value of modern carnations could be improved by increasing the amount of total scent substances as well as the introduction of scents other than methyl benzoate.…”

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.

“…In some old varieties, eugenol contributes up to 85% of total headspace volatiles. Most modern varieties, however, produce low levels of eugenol and lack the characteristic fragrance (Clery et al 1999). Furthermore, not only may fragrance not have been selected for, but it might also have been unintentionally selected against, for example, due to the negative correlation between longevity and fragrance.…”

For centuries, freesia has been one of the most important crops in the floriculture industry. Here, aqua-space samples collected from entire flowers of diploid Freesia refracta, three tetraploid freesia cultivars, and interspecific hybrids of three tetraploid freesia cultivars were analyzed using gas chromatograph coupled with mass selective detector. In all, 75 different compounds were identified. The compounds were mainly terpenes, hydrocarbons, alcohols, fatty acid esters and aromatic class compounds. Among these, linalool was detected from all the sweet-scented flowers except for scentless white tetraploid F. hybrida. Stable inheritance of linalool between F. hybrida and their F1 progeny was observed. Based on the present analyses, the relationship between the aroma of freesia and linalool was discussed.

“…This lack of scent in modern hybrids is not restricted to roses but has also been observed in other Xowers such as carnation (Clery et al 1999). In roses, most scentless Xowers are found in the hybrid tea group which was bred for the cut Xower market and it is not yet clear why this particular type of rose should lack scent.…”

The localization and timing of production and emission of scent was studied in different Rosa x hybrida cultivars, focusing on three particular topics. First, it was found that petals represent the major source of scent in R. x hybrida. In heavily scented cultivars, the spectrum and levels of volatiles emitted by the flower broadly correlated with the spectrum and levels of volatiles contained within the petal, throughout petal development. Secondly, analysis of rose cultivars that lacked a detectable scent indicated that the absence of fragrance was due to a reduction in both the biosynthesis and emission of scent volatiles. A cytological study, conducted on scented and non-scented rose cultivars showed that no major difference was visible in the anatomy of the petals either at small magnification in optical sections or in ultrathin sections observed by TEM. In particular, the cuticle of epidermal cells was not thicker in scentless cultivars. Thirdly, using two different techniques, solid/liquid phase extraction and headspace collection of volatiles, we showed that in roses, both epidermal layers are capable of producing and emitting scent volatiles, despite the different morphologies of the cells of these two tissues. Moreover, OOMT, an enzyme involved in scent molecule biosynthesis was localized in both epidermal layers.
