Abstract: 
The effect of exogenous silicon (Si) on the activity of the major antioxidant enzymes including catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX) and peroxidase (POD) in wheat (Triticum aestivum L.) under drought stress was investigated. Complete randomized design was performed with three treatments control, drought and silicon-drought (1 mmol silicate sodium kg-1) and three replications in the green-house. Result showed that compared to the plants treated with drought alone, Si treatment caused to increase the activity of CAT, SOD, APX, and POD and also the contents of photosynthetic pigments and soluble protein under drought stressed leaves. There was no significant difference in CAT activity between the drought and control treatments. Moreover, among the all studied enzymes, POD revealed the highest activity under silicon treatment. It is concluded that higher activity of antioxidant enzymes and isoenzymes electrophoretic banding patterns are depended to the silicon treatment. Moreover, Si causes to protect the plant tissues from oxidative damage under drought stress. The results of the present experiment coincided with the conclusion that Si may be involved in the metabolic or physiological changes to increase drought tolerance in wheat plant.
