Photosynthetic parameters. a Maximum quantum efficiency of photosystem II photochemistry (Fv/Fm). b PSII operating efficiency (ΦPSII). c Relative electron transport rate (ETR). d Photochemical quenching (1‐qL) and (e) photosynthetic oxygen evolution at different actinic light intensities. Net photosynthetic rate data were fitted with the Hill equation. All data were collected from the cells grown in HS medium at 100 μmol photons m−2 s−1. All the experiment was performed in biological replicates (n > 3). Statistical analysis was performed using Student’s t test (*p < 0.05)
