The study was conducted to observe the effect of Salicylic acid (SA) on physiological and biochemical changes in date palm plantlets. Plantlets were irrigated water with different concentrations of salt stress (10, 15 and 20 ds m−1), while the control treatment wasirrigated by tap water only. The salt concentration significantly decreased chloroplast pigments, total chlorophyll and carotenoid, total soluble carbohydrates compared with increased levels of proline contents and antioxidant activities (catalase and peroxidase). The treatments of date palm plantlets with salicylic acid (1.5 mm) under salt conditions led to increase of leaf chemical composition and antioxidant enzymes activity, catalase and peroxidase compared with treatments under salt stress only and control.
