To replicate these adverse conditions, sodium chloride (NaCl, the most prevalent salt in groundwater and soil) , sodium carbonate (Na2CO3, mimic alkaline stress) , polyethylene glycol (PEG, a commonly reagent for drought simulation), and Pb 2+ (a prevalent toxic heavy metal ion pollutant) , were employed to generate oxidative stress. B. subtilis, recognized for its plant growth-promoting properties and soil environment-meliorating capabilities, was examined for its ability to modulate germination in stressful environments . Six pea varieties, Jade, Vicia faba L, Sweet crispy, Pea sprout 2, ZW6, and ZW11, were tested for each stress condition.
