OJIP curves of ‘Felina 32’ (a) and 'Monoica’ (b) variety plants (Table 2). The presented curves reported average measured data values without the statistic for better curve shape clarity. Point O indicates the origin of the OJIP curve and corresponds to minimal fluorescence Fo, part O–J indicates changes in primary electron acceptor (QA) reduction, J–I indicates changes in reduction of secondary electron acceptor (QB, plastoquinone and cytochrome), point P corresponds with maximum fluorescence value Fm
