From: An innovative light chamber for measuring photosynthesis by three-dimensional plant organs
Apparent quantum yields estimated by fitting data from the P-chamber (αp) and the C-chamber (αc). Each point corresponds to a plant sample, either a wheat ear or a grape cluster. The estimates of apparent quantum yields (mol CO2 mol photon−1) were either calculated directly from the raw photosynthesis data or corrected using equations that take into account irradiance heterogeneity. The line depicts a one-to-one relationship between αp and αc
