The leaf pipeline model of energy fluxes through PSII of excited cross sections (CS) of investigated three sugar beet cultivars (Viola, Jaromir, and Pulitzer) from September to November. Each relative value of the measured parameters is the mean (n = 60) and each arrow’s width corresponds to the flux’s intensity. Yellow arrow—ABS/CS, absorption flux per CS approximated; green arrow—TR/CS, trapped energy flux per CS; red arrow—ET/CS, electron transport flux per CS; blue arrow—DI/CS, dissipated energy flux per CS; circles inscribed in squares—RC/CS, % of active/inactive reaction centers. White circles inscribed in squares represent reduced QA reaction centers (active), black (or orange) circles represent non-reduced QA reaction centers (inactive), 100% of the active reaction centers responded with the highest mean value observed in the control conditions. Means followed by the same letter for each parameter are not significantly different from each other using the Fisher LSD test (P < 0.05). Letters are inscribed into arrows, except for RC/CS, where they are placed in a box in the bottom right corner of the square with circles.
