Two experiments on the effects of air pollution on fertilized potted ramets of eastern white pine, Pinus strobus L., clones were carried out, one in the greenhouse and one in a field area in which sulfur dioxide was believed to be a major pollutant in the natural environment. The greenhouse-grown ramets were artificially exposed to SO/sub 2/ for two hours at 0.25 ppm when the needles were 25-50 mm long. In both experiments known susceptible and resistant clones, in the greenhouse and in the field, were treated with a commercial soluble fertilizer of 28:19:17 formulation at concentrations of 0 to 2 grams per pot and 0 to 32 grams per pot, respectively. Both fertilizer treatments generally increased the resistance of several susceptible clones to air pollution injury. This was most strikingly manifested through reduction of needle tipburn symptoms. In the field experiment, certain other symptoms, such as banding and mottling, were not alleviated by fertilizer application.
