From: An innovative light chamber for measuring photosynthesis by three-dimensional plant organs
Photosynthetic responses by wheat ears at different irradiance levels in the P-chamber and the C-chamber. Net photosynthesis (Pn) in wheat ears that were 2 weeks post anthesis was measured at different PPFD levels in the P-chamber and the C-chamber. Ear temperature was always 25 °C. The means and standard deviations were calculated from four ears with a mean developed area of 22.3 cm2. The lines are described by the Eq. 3
