Effects of strigolactone (SL) and abscisic acid (ABA) levels on photosynthetic parameters in salt-stressed Sesbania cannabina seedlings. a Photosystem II efficiency (ΦPSII) values of S. cannabina seedlings after 2 days under salt stress conditions. b Non-photochemical quenching of chlorophyll fluorescence (NPQ) of S. cannabina seedlings after 2 days under salt stress conditions. c Photosystem II efficiency values of S. cannabina seedlings after 8 days under salt stress conditions. d Non-photochemical quenching of chlorophyll fluorescence of S. cannabina seedlings after 8 days under salt stress conditions. Exogenous signaling molecules (1 μM GR24 and 100 μM ABA) were applied 1 day before the S. cannabina seedlings were exposed to salt stress conditions. Inhibitors (5 mM tungstate and 2 μM TIS108) were applied 1 day before the exogenous signaling molecules were applied. Values are presented as the mean of six independent experiments. The error bar represents the standard error. Data were analyzed using Duncan’s multiple range test. Different letters above the error bars indicate statistical significance at p < 0.05
