Effect of gibberellic acid foliar and kinetin on the antioxidant catalase anzymes and peroxidase in maize under drought stress

Abstract. To study relation between water scarcity and gibberllic acid hormone and kinetin in three hybrids tested corn in two years as a split plot factorial based on randomized complete block design with 3 replications and antioxidant catalase enzymes and peroxidase leaves, the resulted measuremens are that drought stress is a change in the hormonal balance of corn so that amount of catalase and peroxidase enzymes compared to control were increased by foliar of hormones.however most of the characteristics attributed to the use of these hormones had different reactions. But seed function as the main character towards their use indicated a positive effect.
