Salinity is one of the factors limiting the growth and development of the plants that has a negative effect on morphological and physiological processes in plants and in order to reduce these adverse effects used to from growth regulators. In this study, the effect of hormone Salicylic acid (SA) at 3 levels (0, 1 and 2 mM) to relieve stress (NaCl Soluble at concentrations of 0, 50, 100 and 200 mM) consider in licorice plant at germination stage. Seedling length, dry weight and biochemical parameters such as the content of photosynthetic pigment, protein and anthocyanins were analyzed by SPSS software. Recent results showed that high salt concentrations significantly reduced the morphological characteristics. But exogenous 1 mM SA, in salt stress increased the length and weight. Biochemical parameters such as content of photosynthetic pigments, soluble proteins and anthocyanins were also reduced by stress and in the presence SA, anthocyanin content increased significantly compared with control and stress conditions. The positive effect of salicylic acid on the inhibitory effect of lower salt concentration (1 mM) was more than concentration of 2 mM. Also Most inductions observed in Combined treatment of 50 mMNacl with 1 mM SA. On the basis our results, It seems that the use of low concentrations of salicylic acid hormone reduce the harmful effects of salinity in plants.
