title: Air ion exposure system for plants.
abstract: A system was developed for subjecting plants to elevated air ion levels.  This system consisted of a rectangular Plexiglas chamber lined with a Faraday cage.  Air ions were generated by corona discharge from frayed stainless steel fibers placed at one end of the chamber.  This source was capable of producing varying levels of either positive or negative air ions.  During plant exposures, environmental conditions were controlled by operating the unit in a growth chamber.
