SO2sensitive and -tolerant clones of eastern white pine (Pinus strobus L.) were fertilized with a soluble NPK formulation (23:19:17) and artificially exposed to SO2 when the needles were 25 to 50 mm long. Similarly fertilized potted clones were exposed to ambient air in a field where SO2 is believed to be a major pollutant. The fertilizer applications reduced the extent of necrosis of needle tips, a symptom of air pollution injury, in several sensitive clones. In the field experiment other symptoms, such as chlorotic banding and mottling, were not alleviated by the fertilizer applications. Forest Sci. 16:72-73.
