摘要：
The nutrient contents of an acid and a calcareous soil, as well as the foliar contents of four clones of Norway spruce grown on these soils, were evaluated during a 14-month exposure to low level ozone (100 μg m-3 + peaks between 130 and 360 μg m-3) plus acid mist (pH 3·0). Whilst distinct differences could be established between and within clones depending on soil types and genotype, only few pollutant-related effects were observed. Leaching losses from foliage were generally low compared to field studies. The data obtained with young trees in an artificial environment do not support the hypothesis that enhanced leaching from foliage may contribute to nutrient deficiencies in mature stands of Norway spruce. © 1990.
