Salicylic Acid Improves Agro-Morphology, Yield and Ion Accumulation of Two Wheat (Triticum aestivum L.) Genotypes by Ameliorating the Impact of Salt Stress

Wheat growth, development and yield are severely affected by a wide range of abiotic stresses, salt stress is vital increasing stress. Salicylic acid (SA) phenolic phytohormone involved in plant physiological processes. Hence, we have conducted an experiment to explore the roles exogenous SA mitigating two wheat genotypes. There were eight treatments comprising (i) control, (ii) 0.5 mM SA, (iii) 1.0 (iv) 1.5 (v) salinity (12 dS m−1), (vi) + (vii) (viii) with genotypes viz G 200-4 BARI gom-25. The was laid out completely randomized design five replications. During vegetative stage, significantly reduced relative water content (RWC), photosynthetic rate, stomatal conductance growth characteristics both genotypes, while application salt-stressed plants improved RWC, gas exchange activities performance leaf chlorophyll also degraded due treatment, although it mitigated SA. imposition number days required for maturity, yield-contributing Salt increased Na+ concentrations Na+/K+ ratio, K+ decreased However, effects enhancing pigments maintaining lower ratio. Therefore, findings this study suggested that tolerance
