Soybeans, tobacco and peanuts were exposed inside miller-type charcoal filtered chambers and in nonfiltered chambers for 3 week periods during each of two summers at the Georgia Experiment Station, Griffin, to ascertain the effect of oxidants on plant growth. Plants in charcoal filtered air were taller and weighed more than comparable plants in nonfiltered chambers. The oxidant levels, measured as ozone during the daylight hours with a Mast meter, averaged 2.27 and 2.34 pphm for 1973 and 1974. In 1974 dry weights of tobacco and peanuts from the filtered chambers exceeded those of plants from the nonfiltered chamber by 23 and 25%, respectively. Only slight differences occurred in soybean weights. Ozone damage (flecking) was less on Bel W3 in filtered than nonfiltered chambers during both years, but no oxidant type injury was observed on soybeans or peanuts. Greater growth could not be attributed only to the absence of ozone; despite efforts to minimize differences, average temperatures in the filtered chamber exceeded those in the nonfiltered chamber in 1973 by 6.7/sup 0/F and in 1974 by 3.9/sup 0/F.
