The objective of this study was to evaluate, the effect of pre-sowing the plant growth regulators (kinctin and gibberellic acid) treatments on micro nutrients composition of young wheat and barley plants under saline conditions. Barley and wheat seeds were used as seed material. Before sowing, the seeds were soaked in distilled water (Control, Q and in aqueous solutions containing growth regulators in predetermined concentrations (0.5 mM Kinetin (KIN) and 2.0 mM Gibberellic Acid (GA(3))). The soaked seeds were sown in the soil containing four different levels of NaCl (0 (no NaCl), 94, 164 and 240 mM NaCl). In wheat, iron and manganes content decreased as salinity levels increases. Zinc content increased as NaCl concentration up to 164 mM and the highest Zn value obtained from GA(3) treatment in 94 mM NaCl concentration in barley. Generally, GA(3) and Kinetin applications increased Fe, Mn and Zn contents in barley compared to the control. However, the highest values of Fe and Mn and Zn in wheat were obtained from 0 NaCl and treatment that had no hormone.
