Two Different Approaches for Control and Measurement of Plant Functions in Closed Environmental Chambers

摘要

Two approaches are described for the control and measurement of plant functions in environmental chambers; one approach was developed at the US Environmental Protection Agency Research Laboratory in Corvallis, OR, and the other developed at the GSF (Research Center for Environment and Health) in Munich, Germany. Both laboratories needed experimental studies performed under a variety of physical and chemical conditions that can only be faithfully reproduced in the absence of environmental disturbances, typical of field and greenhouse studies. The different goals of each facility determined the different approaches to control and measurement. Both laboratories have many ideas that can be useful to researchers studying the interactions associated with plants and pollutants.
