Abstract Plant response to ozone (O3) is known to be modified by soil moisture deficit, which occurs in varying degrees during most growing seasons. Thus, the authors examined the response of cotton (Gossypium hirsutum) to different levels of seasonal stress by O3 when grown at two soil moisture levels. The cotton was exposed for 12 h/d in open-top field chambers to five O3 doses under well-watered (WW) conditions or under water-stressed (WS) conditions with periodic cycles of low soil moisture. Exposures began when the fifth leaves were expanding and continued for 124 d when most leaves were chlorotic or had abscised. Ozone caused significant yield loss in WW plots but not in WS plots. Results indicate that soil moisture deficit can decrease the impact of O3 on cotton yield.
