Recent light history effects on photophysiology measured under low light.
FRRf-derived photophysiological parameters measured under low light are plotted against in-situ surface PAR at the time of sample acquisition. Panels (a) and (b) show F v / F m and σ PSII measurements made after 5 min of low light exposure. Panels (c) and (d) show NPQ and residual quenching measured...
