Table 2.

Respiration of soybeans leaves grown and measured at ambient and ambient +350 μmol mol⁻¹ [CO₂] for six measurement dates which followed at least two days when mean temperatures were consistently substantially above or below average

Following higher than average temperatures							Following lower than average temperatures
Ambient [CO2]			Elevated [CO2]			Ambient [CO2]			Elevated [CO2]
Actual	Predicted	Actual	Predicted	Actual	Predicted	Actual	Predicted
1·74	1·82	1·37	1·43	1·13	1·13	0·93	0·94

Actual rates were compared with rates predicted from the regressions relating respiration to temperature with the data for those six dates excluded. Each value is a mean for three measurement dates identified in the text. All values are mmol g⁻¹ d⁻¹.
