One of the main problems of rice cultivation and production is the lack of water resources. In this study the effect of applied antioxidants (ascorbic acid , humic acid and seaweed extract ) on endogenous indole acetic acid (IAA), gibberellins (GA), cytokinins (cyto.) and abscisic acid (ABA) contents in two rice cultivars Sakha 101 (as a sensitive cultivar) and Giza 178 (as a tolerance cultivar) were measured under some drought treatment . Results indicated that high drought treatment decreased the promoters hormones (IAA, GA, and Cytokinin) but increased the inhibitor one (ABA). When applied antioxidants were used, the promoters (IAA, GA and cytokinin) increased but the inhibitor was decreased. Data suggested that ascorbic acid is one of the applied antioxidants which enhanced phytohormones content under drought stress in rice.
