The 'classical' action spectra of K. J. McCree (1972) for _Amaranthus edulis_ Speg. var. UCD 1966 and _Avena sativa_ L. var. Coronado are included in this data set. Response is net CO2 uptake measured of leaf sections. Light source was a xenon-arc lamp fitted with a monochromator. Irradiance was in the range 10 to 15 W m$^-2$.
