Effect of zinc and auxin foliar application on some anti-oxidant enzymes activity in corn leaf

An experiment (under controlled condition) was implemented applying randomized complete block design in three replications and eight spraying compound treatments at the agricultural experiment center of Tehran located in Varamin region, in order to investigate the effects of zinc and auxin (IBA) foliar on some anti-oxidant activity, consisting of catalase, super oxide dismutase, peroxidase, poly phenol oxidase and auxin oxidase. Results showed that, of various compounds of zinc (Zinc Sulphate and Zn EDTA) and auxin foliar application were increased level of anti-oxidant enzymatic activities, so it seems that foliar application of zinc and auxin enhance corn tolerance against drought stress via promoting of root growth.
