H₂S Alleviates Salinity Stress in Cucumber by Maintaining the Na⁺/K⁺ Balance and Regulating H₂S Metabolism and Oxidative Stress Response.

ABSTRACT: Salinity stress from soil or irrigation water can significantly limit the growth and development of plants. Emerging evidence suggests that hydrogen sulfide (H₂S), as a versatile signal molecule, can ameliorate salt stress-induced adverse effects. However, the possible physiological mechanism underlying H₂S-alleviated salt stress in cucumber remains unclear. Here, a pot experiment was conducted with an aim to examine the possible mechanism of H₂S in enhancement of cucumber salt stress tolerance. The results showed that H₂S ameliorated salt-induced growth inhibition and alleviated the reduction in photosynthetic attributes, chlorophyll fluorescence and stomatal parameters. Meanwhile H₂S increased the endogenous H₂S level conc
