Aquatic Plant Control Research Program: Methods for Monitoring Herbicide-InducedStress in Submersed Aquatic Plants: A Review

摘要

A technical meeting entitled Physiological Assessment of Herbicide Stress inAquatic Plants was held 10 Jun 1993 at the U.S. Army Engineer Waterways Experiment Station by the Chemical Control Technology Team (CCTT) under the Aquatic Plant Control Research Program. Scientists from universities and government research facilities with common research interests in chemical control of plants and in aquatic weed physiology and ecology were invited to discuss physiological and biochemical methods of verifying and monitoring herbicide effects in submersed aquatic plants. This report summarizes the presentations and discussions by participants on general guidelines for choosing optimal assessment parameters and their suggestions for rapid and simple assays suitable for monitoring physiological changes, whether produced directly by the mode of action of aquatic herbicides or indirectly as a result of loss of metabolic function. Those assays expected to be readily implemented by the CCTT for research assessments of efficacy on target, nontarget, or off-target populations are briefly described.
