Estimated parameters from rapid light curves for Z802 and pgl under low (LL) and high light (HL) by curve fitting.

Genotype-treatment	α	rETRmax (μmol e− m−2 s−1)	Ek (μmol photons m−2 s−1)
Z802-LL	0.246 ± 0.004Bb	97.2 ± 0.8Ab	395.1Ab
Z802-HL	0.253 ± 0.004Aa	83.1 ± 0.7Bb	328.5Bb
pgl-LL	0.255 ± 0.003Aa	160.9 ± 1.3Ba	631.0Ba
pgl-HL	0.250 ± 0.003Ba	185.9 ± 2.1Aa	743.6Aa

α, Photosynthetic efficiency measured by the initial slope of the RLC before the onset of saturation; rETR_max, relative electron transport maximum; E_k, minimum saturating irradiance. Letters A and B indicate significant differences (P < 0.05) between treatments in the same genotype, while a and b indicate significant differences (P < 0.05) between genotypes under the same treatment.
