Effect of abscisic acid (ABA) and H₂O₂ inhibitors on the photosynthetic parameters of arbuscular mycorrhizal Sesbania cannabina seedlings under salt stress conditions. a Photosystem II efficiency (ΦPSII) values of S. cannabina seedlings after 8 days under salt stress conditions. b Non-photochemical quenching of chlorophyll fluorescence (NPQ) of S. cannabina seedlings after 8 days under salt stress conditions. Exogenous signaling molecules and inhibitors comprised 100 μM ABA and 5 mM DMTU. 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
