| Abstract/Contents: | "Elevated ozone levels have exceeded EPA limits in major metropolitan cities. Plant injury due to ozone can result in visible foliar injury, reduced stomatal conductance, and reduced photosynthetic rate, leading to reduced growth and yield of crops. The objective of this study was to evaluate the sensitivity of four turfgrasses and two ornamental monocot groundcovers to elevated ozone levels. Visual damage resulting from ozone fumigation was assessed 48 hours after the start of fumigation. Exposure to 200 ppb ozone for 8 hours on two consecutive days induced severe visual damage to st. augustinegrass (Stenophrum secondatum). After fumigation the quantum efficiency value was significantly lowered in st. augustinegrass, bermudagrass (Cynodon dactylon), Liriope muscari 'Big Blue', L. muscari 'Aztec', and Ophiopogon japonicus (monkeygrass), but zoysiagrass (Zoysia japonica) and centipedegrass (Eremochloa ophuiroides) were not significantly affected by the ozone treatment. Data resulted in differential responses between warm-season turfgrasses to ozone fumigation. Both groundcover species were physiologically impacted, but no visible symptoms were apparent. This study established that measurable effects of elevated ozone levels can reduce plant growth without visible symptoms, depending on the plant species." |
