PSII functional antenna size and PSII maximum quantum yield. a Fluorescence induction kinetics of PSII antenna size of wild type and selected mutant. b PSII functional antenna size expressed as the reciprocal of the time required to reach 2/3 of the maximum fluorescence emission, τ−12/3(%). c PSII maximum quantum yield calculated as (FM-F0)/FM from basal chlorophyll fluorescence in the dark (F0) and maximum chlorophyll fluorescence induced by a saturating pulse (FM). The statistical analysis of the results obtained was performed by unpaired two-sample t-test (n = 4, no statistically significant difference being p-value = 0.09 for PSII functional antenna size and p = 0.78 for Fv/Fm values)
