Fig. 8

Maximum quantum yield (Fv /Fm) of whole Ely rosettes and 3 indicated individual leaves per panel (leaf number indicated: (A) for leaf 1 to 3, (B) for leaf 4 to 6, (C) for leaf 7 to 9, (D) for leaf 10 to 12 and (E) for leaf 13 to 15) determined over time (as timepoint or as days after sowing, DAS). Schematic representation of the fluctuating light treatment over time is shown in the top panel, with 300 μmol m⁻² s⁻¹ of constant irradiance, 100 μmol m⁻² s⁻¹ of low irradiance and 900 μmol m⁻²s⁻¹ of high irradiance levels. The mean Fv /Fm values are shown with solid lines, with shaded regions above and below indicating standard errors of the means. Data points represent 8 replicates
