A foliar disorder of Austrian pine observed in New Jersey since 1967 was found to result from a mixture of ozone and sulfur dioxide. In fumigation chamber studies, a mixture of 0.2 ppm ozone and 0.1 ppm sulfur dioxide for 6 hr reproduced symptoms observed in the field. Grafted material originating from trees that exhibitied either a sensitive or resistant response in the field gave the same differential response in the experimental fumigation. Needles of resistant trees had higher stomatal resistance and higher soluble sugar content than needles of susceptible trees.
