Wheat is important food for more than 35% of the world’s population and its cultivation is mainly limited to such areas with water scarcity. The current study involves studying changes in the accumulation of glycine betaine, membrane stability, chlorophyll, protein and Malon (MDA) Di Aldelyde of ten varieties of durum wheat under stresses. The results of this study showed a significant decrease in the accumulation of glycine betaine, relative water content, membrane stability, chlorophyll content, MDA. The study showed that varieties responded to water stress with different mechanisms in different proportions between varieties to maintain the vital functions of the durum varieties studied.
