Abstract:
At the end of the experiment, electron transport rates irradiance curves were conducted applying 8 irradiances from 0 up to ~400 μmol photons m-2 s-1 for 5 min for each light level. A light sensor (ULM-500, Walz GmbH, Effeltrich, Germany) measured each light intensity (E, μmol photons m-2 s-1) emitted from the FastAct Laboratory system.
