Net Co2 assimilation rate (A), intercellular CO2 concentration (B), stomatal conductance (C), transpiration (D), intrinsic (E) and instantaneous water use efficiency (F), instantaneous carboxylation efficiency (G) of Capsicum annuum in response to different salinity levels and biostimulant doses. *The values with the different alphabetical letters differ significantly, based on the Tukey test at 5%. Data represent the average of 5 replication as mean, and each replication represents one plant.
