Grass and legume plants were grown under near-optimum conditions in
controlled-environment cabinets. Changes in net photosynthetic rate, dark respiration
rate, and carbon dioxide transfer resistances during leaf ontogeny, and variability
between leaves on grass tillers and legume runners were studied under controlled
conditions in an open gas analysis system.
Grasses and legumes were grown at two temperatures in controlled-environment
rooms and at three illuminances (obtained by shading) in a glasshouse. Carbon
dioxide and water vapour exchange of leaves were measured in an open gas analysis
system.
