Measurement of carbon fixation and allocation using 11C-labeled carbon dioxide

This paper describes the use of continuously produced and applied 11C in measurements of carbon dioxide assimilation and C movement in plant research. This technique differs from the pulsing type 11C research underway in other laboratories by being continuous and on-line with computer analysis making steady-state measurements of carbon fixation and movement possible. The studies to be described here make clear the advantages of using continuously produced and applied short half-lived isotopes
