The effect of ozone (<10, 200, or 400 μg m −3), on foliar nutrient concentrations of Picea abies were determined by fumigating potted grafts from mature trees (>55 and 125 years), representing six clones, in open-top chambers at two locations in Norway. The concentration of nutrients in needles of grafted plants were significantly affected by clone and location. Generally, the concentrations of nutrients were not affected by ozone, but a significant increase in the concentrations of potassium and iron in two of the clones were found. These two clones were the only ones injured (yellow needles) by the fumigation.
