^aChl a content was measured spectrophotometrically

^bPSI and PSII content were calculated from the Chl a content and PSI:PSII ratio

^cPSI:PSII ratio was estimated from deconvolution of the 77 K fluorescence spectra

^dPC content was calculated from the Chl a content and PC:Chl ratio

^ePC:Chl ratio was estimated from the absorption spectra

^fPC:PSII ratio was calculated from the PC and PSII content
