The higher growth rate of P. haitanensis in CK, B, and G light compared to others can be explained to some extent by the higher photochemical electron transport rate and thereby a higher efficiency of photochemical action and photosynthetic efficiency. The V/ (photosynthetic efficiency), (light use efficiency, the slope of the photosynthesis versus irradiance curve), rETRmax (defined as the photosynthetic capacity), and qP (photochemical quenching) are frequently used to represent the maximum photochemical efficiency of PSII and proportion of oxidized (open) reaction centers with PSII used as an index of photosynthetic efficiency [28].
