| Abstract: | The effects of the exogenous application of salicylic acid (SA) on the germinating response of durum wheat seeds (Triticum durum, Desf.) were studied under salt stress conditions. In this study, an assay was conducted on a group (SA) composed of seeds treated with 0.04 mM SA, a second group (NaCl) treated with 120 mM NaCl and another group (SA / NaCl), pretreated by SA and submitted at a salt stress. In the control group (C) we use only distilled water. The measured parameters are the Germinating Capacity (GC), the Daily Average of Germination (ADG), the Kinetic of Germination (KG), the Germination Rate (t50), the Mobilization of Reserves during germination, represented by the Residual Dry Matter (RDM), the Proline and Glutathione (GSH) content. The results show that GC is not affected by the addition of (SA) and in the group pretreated by SA and subjected to salt stress (SA / NaCl). At the same time, the application of NaCl (120 mM) greatly reduces GC. NaCl decreases the germination rate and inhibits the process of mobilization of reserves while decreasing ADG compared to SA and SA / NaCl group. A significant increase in the level of proline is recorded (300%) in the group (NaCl) contrary to the rates obtained after pretreatment with SA and which are similar to those obtained in the group C. Finally, the variations observed with GSH in the presence of SA, highlight an important link between the role of this compound as an antioxidant and the tolerance of seeds to salt stress (NaCl). |
