Other claims from this paper (4)
- Observation Field-grown winter wheat showed saturation of net photosynthesis at high irradiance.
- Association As irradiance decreased, field-grown winter wheat net photosynthesis decreased proportionally.
- Method / resource Controlled-environment wheat showed a photosynthesis-light curve better fitted by a rectangular hyperbola.
- Recommendation The authors warn that laboratory photosynthesis-light responses may not extrapolate to the field.
