The effect of water stress on 4 enzymatic systems: peroxidases, malate dehydrogenases, esterases and phosphatases of coleoptiles and roots of two varieties of durum wheat Karim and Tomouh was evaluated by electrophoretic analysis.
Water conditions have stimulated the synthesis of peroxidases in the coleoptiles and malate dehydrogenases in the roots of both varieties studied. Drought has also induced the synthesis of peroxidases, esterases and phosphatases at the roots of variety Karim.
