The drought tolerance with a low water potential require a thorough understanding of the mechanisms involved in osmotic adjustment. This paper discusses the various biochemical parameters of ten durum wheat genotypes, conducted under three water regimes (SDH, ADH1et ADH2). The aim of the present study was to explain these processes in the genetic variability offered by the durum wheat subjected to different intensities of water deficit. The obtained data showed that the water deficit caused a decrease in the osmotic potential. The synthesis and accumulation of sugars were determined by the physiological state of the plant and the level of water stress.
