Various factors affect the CO2 compensation point of detached leaves of Lolium perenne L. These include oxygen concentration, temperature, leaf age, and season (spring and summer). Analysis of the results using the model of G.D. Farquhar, S. von Caemmerer and J.A. Berry (1980) Planta 149, 78–90, indicates that some of the CO2 evolved by leaves in the light is derived from sources other than photorespiration. It is suggested that the operation of the tricarboxylic acid in the light can account… CONTINUE READING
