Salicylic acid (SA) is considered to be a very important signal molecule involved in the plant development processes and mainly involved in some agricultural plants response to different abiotic stress factors and plays a major role in the physiology of stress plants. Salinity is one of the major abiotic stresses. Many crops species are sensitive to salinity. Salt stress causes oxidative damage and alters the amounts and activities of the enzymes involved in scavenging oxygen radicals. In this paper we study the effect of pre-soaking seeds in 0.05 or 0.1 mM SA solutions. The experiments will be conducted under field conditions, growing in pots, on some physiological and biochemical parameters modification like: plant height, photosynthetic rate, stomatal conductance, assimilatory pigment contents, proline and other amino acid content in salt stressed wheat seedlings. Salt stress was simulated by irrigation of the wheat seedlings with 0.2M NaCl solution. The highest enhancements of the tolerance to salinity on Triticum aestivum cv. Crisana, plantlets were recorded in the case of treatments with 0.1 mM SA solution.
