Fifth International Congress of Plant Pathology, Kyoto, Japan, August 23-27, 1988: Foreign Trip Report

摘要

The traveler was invited to present two papers at Symposium XV of the Fifth International Congress of Plant Pathology. The major topics of the sessions within the symposium were (1) physiological and biochemical responses to air pollution, (2) air pollution-vegetation effects models, (3) joint action of multiple pollutants, and (4) acidic deposition. In the last session, the traveler presented two papers on the effects of air pollutants on forests. One described results of ongoing ORNL research on the physiological responses of red spruce to ambient pollution levels at high-elevation sites in the Great Smoky Mountains. The second provided an overview of the research being done in the Southern Commercial Forest Research Cooperative and used selected results from ORNL and other programs to illustrate results reported to date. Relevant information was obtained from several papers on mechanisms of action of chronic air pollution stress; this information may be useful in evaluating the mechanistic basis of pollutant impacts on forest trees. 20 refs.
