| Main components of the headspace of flowers of the beautiful hybrid tea rose //‚Baronne E. De Rothschild’// (purple-Solferino petals with a silvery reflection on the underside), collected on Tenax, were esters (91.1%), mainly (Z)-3-hexenyl acetate (45.1%), and hexyl acetate (32.9%). \\ | Main components of the headspace of flowers of the beautiful hybrid tea rose //‚Baronne E. De Rothschild’// (purple-Solferino petals with a silvery reflection on the underside), collected on Tenax, were esters (91.1%), with large amounts of (Z)-3-hexenyl acetate (45.1%) and hexyl acetate (32.9%). \\ |
| //,Sutters Gold‘// (with copper yellow petals veined by orange and carmine) is characterized by an oriental rose scent with fruity (cherry) and cognac undertones. The dominating esters (75.5%) included (Z)-3-hexenyl acetate (23.7%), hexyl acetate (26.8%), phenylethyl acetate (16.3%), and geranyl acetate (4.2%). Orcinyl dimethylether (3,5-dimethoxytoluene; DMT; 14.2%) was distinctly present, together with phenylethanol (3.2%), nerol (2.8%), citronellol (1.8%), and also the rose oxides (0.18%). \\ | //,Sutters Gold‘// (with copper yellow petals veined by orange and carmine) is characterized by an oriental rose scent with fruity (cherry) and cognac undertones.

| | //'Meispola'// ('Yonina') is a variety of hybrid tea rose with distinctive elegant double pure white blossoms having a delicate fragrance. Main group of components were esters (55.8%), like (Z)-3-hexenyl acetate (26.5%), hexyl acetate (26.2%), and geranyl acetate (2.1%), alongside 3,5-dimethoxytoluene (DMT; 29.0%) and citronellol (5%). \\ |
| | The hybrid tea rose //'Fragrant Cloud'// ([[https://de.wikipedia.org/wiki/Duftwolke|'Duftwolke']], 'Fragrant Cloud'), showed also esters esters (48.8%) as the most abundant components, like phenylethyl acetate (19.3%), hexyl acetate (12.3%), (Z)-3-hexenyl acetate (9.7%), and citronellyl acetate (7.1%). Olfactorly interesting compounds were also phenylethanol (14.8%), citronellol (5.8%), p-vinyl anisole (11.0%), β-ionone (0.7%), rose oxides (0.2%), and estragol (0.1%). \\ |
| | Ther are varieties containing mor than 40% of DMT ('aromatic ether type'). //'Sylvia'// ([[https://www.helpmefind.com/rose/l.php?l=2.16733.2|W.Kordes]]) had DMT (67.3%) together with anisole (0.1%), p-vinylanisole (1.1%), β-ionone (2.7%), rose oxides (0.5%), nonanal (0.9%), and decanal (0.9%). \\ |
| | //'Youki San'// ('Meidonq') showed DMT (55.8%), anisole (1.4%), p-vinylanisole (0.6%), together with hexyl acetate (3.3%), (Z)-3-hexenyl acetate (1.6%), and a tpiycal scent derived from phenylacetaldehyde (1%). \\ |
| | //'Papa Meilland'// is a dark velvet red tea hybrid rose with a lemon peel note added to the typical classical rose scent. Aromatic ethers present are DMT (40.3%), accompanied by benzyl methyl ether (2.7%), and p-vinylanisole (1.6%). Other major components were citronellol (29.4%), phenylethanol (1.8%), hexyl acetate (12.6%), citronellyl acetate (3.1%), rose oxides (1.5%), and β-caryophyllene (1.0%). \\ |

| In the case of the hybrid tea rose 'Fragrant Cloud' ([[https://de.wikipedia.org/wiki/Duftwolke|'Duftwolke']], 'Nuage Perfume', 'Tanellis') it has been shown that emitted amounts of volatiles of uncut or cut flowers may be the same, with identical rhythm of individual components. This rose emitted (Z)-3-hexenyl acetate (max. 12% of total volatiles), n-hexyl acetate (max. 2.2%) and (Z)-2-hexenyl acetate (max. 4.6%) with peak output between 8-12 a.m., and on the other side, citronellol (10%) after noon till night. Geraniol had peaks at 8 a.m. in the morning and at noon (8%). \\ | In the case of the hybrid tea rose 'Fragrant Cloud' ('Nuage Perfume', 'Tanellis') it has been shown that emitted amounts of volatiles of uncut or cut flowers may be the same, with identical rhythm of individual components.
