Abstract Ponderosa Pine (Pinus ponderosa Laws.) seedlings grown in field exposure chambers and fumigated with ozone at a concentration of 200 g/cu m 6 h/day; 7 days/wk for variable periods of up to 20 weeks. Pines were harvested at 4 wk intervals to determine the levels of the metabolites in tops (stem and needles) and roots. The ozone exposure affected the metabolite pools in the roots and tops differentially. The ozone treatment had no effect on the nitrogen or amino acid content of the tops but increased the levels of these pools in the roots. The levels of the soluble sugars, starch, and phenols tended to increase in the tops and decrease in the roots of the ozone-exposed plants. The ozone treatment had no effect on the lignin content in either the roots or the tops.
