abstract = {Ozone is a powerful oxidizing agent which is responsible
for more damage to vegetation than any other air pollutant.
In this study, leaf growth, photosynthesis, and carbohydrate
content were analysed during the seed-filling growth stage
of field-grown soybeans exposed to ambient air and 1.2 times
ambient ozone concentration using a Free Air Concentration
Enrichment (FACE) facility. By contrast to predictions based
on controlled-environment and open-top chamber studies,
final yield did not differ between treatments, although the
cultivar used here was sensitive to ozone damage: growth and
carbohydrate content of upper canopy leaves was reduced
during the seed-filling stage in which an ozone-induced
decrease of photosynthesis was present. However, 2004 was an
ideal growing season in central Illinois and the cumulative
ozone indices were lower than in previous years. Still, the
results indicate that the anticipated yield loss under ozone
concentrations was avoided at the expense of leaf growth, as
reserves were diverted from vegetative to reproductive
organs.},
