Hydrogen sulfide pretreatment mitigates the adverse effects of salinity in young carob seedlings.

ABSTRACT: Despite the inherent high salinity tolerance of mature carob (Ceratonia siliqua L., Fabaceae) trees, young seedlings are particularly vulnerable to salt stress, which can hinder their growth and development. Although hydrogen sulfide (H₂S) has been widely studied as a regulator of salinity tolerance in herbaceous plants, its role in woody legumes remains largely unexplored. This study aimed to explore the potential of hydrogen sulfide (H₂S) pretreatment to enhance the salinity tolerance of young carob seedlings. A pot experiment was conducted using a factorial design to evaluate the effects of sodium hydrosulfide (NaHS, an H₂S donor) at 0, 75, and 200 µM under saline conditions (0, 50, and 100 mM NaCl). The results indicated that H₂S pretreatment enhanced t
