Abstract
An apparatus is described for measuring photosynthetic CO2 assimilation, dark respiration, photorespiration and the CO2 compensation point by plant materials fumigated with the atmospheric pollutants SO2 and/or O3. This system uses an IR gas analyzer (IRGA) in a closed-loop system. SO2 is added from permeation tubes and O3 is generated by UV light. Regulation of fumigant concentration and scrubbing the fumigants from the system are described.This publication has 2 references indexed in Scilit:
