Abstract
CHLOROTIC dwarf disease of eastern white pine (Pinus strobus L.) is a physiogenic condition characterized by stunted roots and tops, mottled needles and premature foliar abscission. Recent work has indicated that the disease is caused by gaseous pollutants that injure the needles of genetically susceptible white pines1. We have now shown that the action and interaction of ozone and sulphur dioxide cause characteristic symptoms on the foliage of white pine ramets that are susceptible to chlorotic dwarf.
