Results showed that NaCl reduced K⁺, Ca²⁺ and Mg²⁺ concentration in shoot and root. Applied of KCl and CaCl₂ led to significant increasing of root weight. Also effect of KCl on Na⁺ concentration in root and shoot was significant. A negative and significant correlation was seen between Na⁺ and Ca²⁺. KCl and CaCl₂ increased in Cl^- concentration in root and shoot. NaCl caused to raise the chlorophyll <em>b</em> content while carotenoids concentration was decreased. Soluble proteins, peroxidase and ascorbat peroxidase activities were increased under NaCl stress. <em> </em> In order to investigate the effect of sodium chloride, potassium chloride and calcium chloride on organic and inorganic solutes and antioxidant enzymes activity in root and shoot of Alfalfa (Baghdaadi cultivar), a factorial experiment base on CRD was conducted using NaCl (0, 100 mmol), KCl (0, 40 mmol) and CaCl₂ (0 and 20 mmol) with four replications in greenhouse of Islamic Azad University (Khorramshahr branch) at 2010.
