In this context, chlorophyll fluorescence analysis
(CFA) and, in particular, chlorophyll fluorescence imaging (CFI)
may provide an elegant means to non-invasively and rapidly
monitor early changes in photosynthetic properties (von Willert
et al., 1995; Maxwell and Johnson, 2000; Cséfalvay et al., 2009;
Herppich et al., 2012).
