TECHNIQUES FOR MEASURING CO₂ ASSIMILATION IN CONTROLLED-ENVIRONMENT ENCLOSURES

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.
