abstract = {Volatile organic compound (VOC) emissions from tobacco
(Nicotiana tabacum L. var. Bel W3) plants exposed to ozone
(O3) were investigated using proton-transfer-reaction
mass-spectrometry (PTR-MS) and gas chromatography
mass-spectrometry (GC-MS) to find a quantitative reference
for plants’ responses to O3 stress. O3 exposures to
illuminated plants induced post-exposure VOC emission
bursts. The lag time for the onset of volatile C6 emissions
produced within the octadecanoid pathway was found to be
inversely proportional to O3 uptake, or more precisely, to
the O3 flux density into the plants. In cases of short O3
pulses of identical duration the total amount of these
emitted C6 VOC was related to the O3 flux density into the
plants, and not to ozone concentrations or dose–response
relationships such as AOT 40 values. Approximately one C6
product was emitted per five O3 molecules taken up by the
plant. A threshold flux density of O3 inducing emissions of
C6 products was found to be
(1.6 ± 0.7) × 10−8 mol m−2 s−1.},
