Description of the subject: Salicylic acid (SA) is considered to be a potent plant hormone in preventing germination seeds in many plants. Objective : The present study was to compare the effect of different concentration of salicylic acid (SA) on the germination vigour and rooting ability of two varieties of Pistacia vera L. (Bayadhi and Achouri) subjected to salt stress. Methods : Seeds were pretreated with four concentrations of salicylic acid (0.25 – 0.5 – 0.75 and 1 mM), and then sprayed with H2O and NaCl solution. The untreated seeds were used as control. The following parameters were evaluated; germination speed, germination percent and radicle elongation. Results: The obtained results showed a reduction in germination parameters of the untreated seeds (control), especially in presence of 100 mM NaCl compared to 50 mM NaCl. However, the SA treated seeds performed better than the untreated seeds. Significant difference between the treatments effect on germination were observed at p≤0.05. The doses of 0.25 and 0.5mM SA had a positive effect on the speed, the rate of germination and the radical elongation than 0.75mM SA, even when seeds were sprayed with water or solution of NaCl. On the other hand, the dose of 1mM SA produced a significant reduction of germination and root elongation, in the presence or the absence of salt stress. Conclusion : It can be concluded that the lowest doses of salicylic acid increased significantly the germination performance compared to the highest doses depending on the dose used and the variety.
