A novel system was created to expose plants to controlled levels of positive or negative air ions. This setup allows for precise environmental control during plant studies involving air ionization.

Area of Science:

  • Plant science
  • Environmental science
  • Atmospheric science

Background:

  • Air ions can influence biological processes.
  • Controlled studies are needed to understand plant responses to air ions.
  • Existing methods may lack precise control over ion levels and environmental conditions.

Purpose of the Study:

  • To develop and describe a system for exposing plants to controlled levels of air ions.
  • To enable the study of plant responses under varying positive and negative air ion concentrations.
  • To facilitate research on the effects of air ionization on plant physiology.

Main Methods:

  • A Plexiglas chamber lined with a Faraday cage was utilized.
  • Air ions were generated using corona discharge from stainless steel fibers.
