TECHNIQUES FOR MEASURING CO2 ASSIMILATION IN CONTROLLED-ENVIRONMENT ENCLOSURES

D.W. Hand
The CO2 assimilation rate of plants over short periods can be measured in controlled-environment enclosures sometimes referred to as cuvettes. Different methods of analysing CO2 uptake in which the plant enclosures can be part of "open", "closed" or "mixed" systems are reviewed.

A null-balance method for measuring the CO2 assimilation rates of crop stands over periods of 30 minutes or less in either "open" or "closed" circuit controlled-environment daylit enclosures is described, and instrumentation suitable for measuring and controlling CO2 concentration in such enclosures is considered.
