EFFECT OF SALICILYC ACID ON ASSIMILATORY PIGMENTS AND AMINOACIDS CONTENT IN SALT STRESSED WHEAT (TRITICUM AESTIVUM, CV. CRISANA) SEEDLINGS

Abiotic stress causes drastic yield reductions in most crops. Salinity is one of the major abiotic stresses and researchers are trying to find the most suitable substance to enhance plant tolerance to stress factors. One of these substances is Salicylic Acid (SA). It has a significant impact on the various aspects of the plant life. In this paper we study the effect of presoaking seeds in 0.05 or 0.1 mM SA solutions in pot experience, on some biochemical parameters modification like: assimilatory pigment contents, proline and other free aminoacid content in salt stressed wheat seedlngs. 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 cultivar Crisana, plantlets were recorded in the case of treatments with 0.1 mM SA solution.
