Rooted cuttings of hybrid poplar (Populus maximowiczii x P. trichocarpa, clone 388) were exposed in a controlled chamber to 400 ..mu..g/m/sup 3/ of ozone for 5 hr two, three, four, or five times during a 1-month period. About 60-80% of the leaves developed toxicity symptoms on 10-25% of the total leaf area. Ozone had no statistically significant effect on total dry weight, leaf area, elongation, relative growth rate, or net assimilation rate of the total plant population, but the trend was toward a reduction in each of these variables. A few individuals were more susceptible than the majority, and their growth was obviously inhibited. 33 references, 3 tables.
