abstract = {Emissions of oxygenated volatile organic compounds (OVOC)
from several plant species were measured in continuously
stirred tank reactors (CSTR). High emission pulses of OVOCs
were observed when plants were exposed to stress. Absolute
emission rates were highly variable ranging up to 10(-13)
mol.cm(-2).s(-1). The temporal shape of these emissions was
described by a formalism similar to that of a consecutive
reaction of pseudo first order kinetics. The main emitted
OVOC was (Z)-3-hexenol together with other C-6-aldehydes and
alcohols, suggesting that lipoxygenase activity on linolenic
acid was mainly responsible for OVOC production. Various
stress factors induced lipoxygenase activity and subsequent
emissions of OVOCs. These factors were exposure to high
ozone concentrations, pathogen attack, and wounding. The
pattern of OVOC emissions from tobacco was similar for
different stress applications and the same products of
lipoxygenase activity were emitted from all investigated
plant species. Our results imply that these emissions occur
as general response of the plants to stress. Since plants
experience various abiotic or biotic stress factors in the
environment, OVOC emissions as a response to stress are
likely to be of significant importance for atmospheric
chemistry.},
