Abstract

Salicylic acid (SA), a plant phenolic compound is considered as a plant growth regulator and its role in the defense mechanisms against biotic and abiotic stresses has been well characterized. This experiment was conducted to investigate the impact of SA on growth, physiology and biochemical parameters ofTriticum aestivum grown under salt stress. For this purpose, TRITICUM AESTIVUM L (Shiraz and Star cultivars) seeds were soaked in SA (0, 0.5 and 1 mM) and then SALINITY was applied by NaCl (0, 100 and 200 mM). FW (fresh wight), photosynthetic pigment and total protein contents decreased sharply with increasing stress levels. Prolin, MDA and H2O2 content increased significantly under salt stress. However, seeds pretreated with salicylic acid along with the SALINITY levels showed enhancement in growth parameters, photosynthetic pigments, and total protein content, while proline, MDA and H2O2 levels decreased. The results showed that deleterious effects of SALINITY in TRITICUM AESTIVUM plants were significantly encountered by the pretreatment with salicylic acid. It is concluded that salicylic acid could ameliorates the negative effects of SALINITY in TRITICUM AESTIVUM cultivars.
