Abstract:Hydrogen sulfide (H2S) has emerged as a potential regulator of plant responses to abiotic stress. In this study, we investigated the effects of exogenous sodium hydrosulfide (NaHS) on tobacco seedlings subjected to polyethylene glycol (PEG)-induced drought stress. Compared to control conditions, drought stress significantly reduced several parameters in tobacco seedlings, including shoot dry weight (22.83%), net photosynthesis (37.55%), stomatal conductance (33.56%), maximum quantum yield of PSII (Fv/Fm) (11.3… Show more
