Abstract -

Ambient, ground-level ozone is the most important air pollutant affecting vegetation in the US. However, ozone-sensitive bioindicators need to be identified for use in field surveys to detect ozone-induced symptoms. To identify such bioindicators, 28 plant selections were exposed to ozone within greenhouse chambers during 2003 and 2004. Plants most sensitive to ozone included Asclepias incarnata (swamp milkweed), Asclepias syriaca (common milkweed), Cephalanthus occidentalis...
