Maximal quantum yield of PSII (Fv/Fm) (a) and effective quantum yield of PSII (ΦPSII) (b) of S. salsa plants grown in sand in medium containing 0 and 200 mM NaCl at the beginning of the reproductive growth stage (103 DAS). Values are presented as the means ± SD of five replicates. Different letters indicate a significant difference at P < 0.05 according to Duncan’s test
