A Re-evaluation of Soybean Leaf Photorespiration 1

RESUMO
Recalculations of soybean photorespiration indicate that mean rates are closer to 16.1 than 5.6 milligrams of CO2 per square decimeter per hour as previously reported. Photorespiration of soybean thus amounts to at least a 30% carbon turnover of light-saturated photosynthesis. Photorespiration showed no significant relationship to net photosynthesis. Negative correlations were found between CO2 efflux and stomatal resistance as well as between corrected photorespiration and residual intracellular resistance of the leaf to CO2 uptake.
