Table 1: Percentages of volatile compounds in _Onc_. Rosy Sunset. In this study, the results showed that daily rhythm, flowering period, and temperature affected aroma emissions. These results were also showed in _Onc._ Sharry Baby; the odor was strongest during the flowering stage and in a 30 \({}^{\circ}\)C environment, on the other hand, the lower temperature reduced the number of volatile compounds and relative content [10; 12].
