Abstract A field experiment was conducted in open-top chambers to determine how interactions of soil moisture stress and exposure to ozone may affect soybean yields. Cultivars Williams and Forrest were grown in 1982 and Williams & Corsoy in 1983. Five levels of O3-including charcoal-filtered (CF) and nonfiltered(NF) air- and two soil moisture regimes(averaging -0.05 M Pa, and about -0.40 M Pa at depths of 0.25 and 0.45m) were employed. This report describes a significant interaction involving soil moisture stress(SMS) and the CF and NF air treatments. These results provide the first experimental evidence that exposure to elevated ambient O3 may cause plants to lose tolerance to SMS.
