False-colored chlorophyll fluorescence images of whole plants obtained during constant, 100 μmol photons m−2 s−1 actinic illumination over a 16 hr photoperiod. Measurements and calculations were performed as described in Materials and methods. Images were false colored according to calculated values, from magenta (high) to blue (low).
