A comparison was made of the nature and severity of symptoms developed on ozonated bean plants (Phaseolus vulgaris) grown in a greenhouse, growth chamber, and open-top chamber. Data show that a significant difference occurs in the ozone response of greenhouse and growth chamber plants compared to open-top chamber plants both in respect to symptom and sensitivity. It was concluded that results obtained in greenhouse studies cannot be extrapolated to the field; therefore their usefulness in setting ambient air standards should be questioned. A further question was raised as to why bean plants which are relatively sensitive to single high doses of ozone develop definite toxicity symptoms with continuous exposure to low concentrations of the pollutant. Preliminary evidence indicates that continuous low levels of oxidant predispose a plant to injury. There is also the possibility that a second pollutant acts synergistically with ozone to produce the observed damage.
