Abstract: | "The floral scent emission and endogenous level of its components in Petunia axillaris under different conditions (20, 25, 30, and 35 degrees C) were investigated under the hypothesis that floral scent emission would be regulated by both metabolic and vaporization processes. The total endogenous amount of scent components decreased as the temperature increased, the total emission showing a peak at 30 degrees C. This decrease in endogenous amount was compensated for by increased vaporization, resulting in an increase of floral scent emission from 20 degrees C to 30 degrees C. The ambient temperature differently and independently influenced the metabolism and vaporization of the scent compounds, and differences in vapor pressure among the scent compounds were reduced as the temperature increased. These characteristics suggest the operation of an unknown regulator to change the vaporization of floral scent" |
