Tall fescue and red brome plants were grown from seed and planted in pots. Plants were exposed once per week for six hours to 0.2 ppm ozone, 0.2 ppm sulfur dioxide, 0.2 ppm ozone plus 0.2 ppm sulfur dioxide or a charcoal-filtered control in greenhouse fumigation chambers. The length of exposure period was 24 weeks for tall fescue and 16 weeks for red brome. Plants were harvested on a weekly basis. The most pronounced effects were due to ozone which adversely affected dry weight and quality. The effects of sulfur dioxide were less severe and were generally confined to quality parameters.
