Résumé :	"Soil salinity is one of the major and increasing problems of the agriculture worldwide, particularly in wheat growing areas. Durum wheat (Triticum durum Desf.) is an important cereal crop and source of staple food for many countries, where its production is mainly البيولوجيا threatened by salinity. The present study was conducted for two purposes. The first one was to promote the salt tolerance of durum wheat by priming seeds with hormones (GA3) and/or antioxidants (ascorbic acid). The results indicated that the effect of salinity upon almost all the germination, growth and metabolism parameters of wheat embryo or seedling can be alleviated by seed priming using GA3 and/or AsA. The second was to investigate the potential biomarkers of mechanisms underlying salt tolerance induced by ascorbate-priming by using proteomic technology. Our results revealed the involvement of more than 160 metabolic proteins on the determination of seed vigor or priming-induced salt tolerance, predominantly those involved in oxidative stress defense, protein synthesis and turnover and phytohormones biosynthesis namely auxin. Altogether, these results extend our understanding about salt stress tolerance in plants, and provide valuable information for breeding programmes to improve salt tolerance in durum wheat.
