Figure 3. Conversion of (Z)-3-hexenal in intact Arabidopsis (Col-0).

Intact Arabidopsis (Col-0) plants were exposed to (Z)-3-hexenal vapor (1.0 nmol cm⁻³), transferred into a fresh glass container, and the amounts of (Z)-3-hexenyl acetate (white bars) and (Z)-3-hexenol (black bars) emitted from the plants were quantified. Control plants were exposed to CH₂Cl₂ vapor (carrier solvent for volatiles). Error bars represent SE (n = 3). Data were analyzed by Tukey's test. Different letters above the bars indicate significant differences among treatments in the emission of each compound (P<0.05).
