Estimation of Photorespiration Rate by Simultaneous Measurements of CO₂, Gas Exchange Rate, and Chlorophyll Fluorescence Quenching in the C₃ Plant Vigna Radiata (L.) Wilczek and the C₄ Plant Amaranthus Mongostanus L.

So far the photorespiration rate (R _P) in a leaf has been determined as the difference between the net photosynthetic rates (P _N) measured in 21 % O₂ air (P _N21%) and 3 % O₂ air (P _N3%). In the C₃ plant Vigna rad...
