Abstract

In order to investigate the response of Zinc-efficient and Zinc-inefficient of Bread wheat cultivars to soil Zinc (Zn) deficiency, the present factorial experiment was conducted in a greenhouse in a completely randomized design with three replications. The factors of the experiment were including Zinc levels at two conditions Zinc-adequate (five milligram Zincper kilogram soil) and no Zinc application, Zinc-efficient cultivars (Bayat and Niknejad) and Zinc-inefficient (Hirmand and Karaj1), sampled tissues (root and leaf) and growth stage (28 days after germination and 30 percent of heading as vegetative and reproductive stages, respectively). In the present research the activity of superoxide dismutase, Catalase, ascorbate peroxidase, peroxidase and phenylalanine ammonia-lyase enzymes and also the content of malondialdehyde, hydrogen peroxide, prolin, phenol compounds and total antioxidantswere measured. The results of variance analysis and mean comparisons for main and interaction effects revealed that under Zinc deficiency conditions, the activity rate of ascorbate peroxidase enzymes, peroxidase and phenylalanine ammonia-lyase increased while the activity of superoxide dismutaseenzymes significantly (P≤ 0. 01) declined. The content of malondialdehyde, hydrogen peroxide, phenol and proline significantly (P≤ 0. 01) increased under Zinc deficiency conditions. Also, the enzymes activity superoxide dismutase, Catalase, ascorbate peroxidase, peroxidase, phenylalanine ammonia-lyase and prolin content in Zinc-efficient cultivars were higher and whereas the amount of malondialdehyde and hydrogen peroxide were minimum in these cultivars. The rate of Catalase enzyme activity in Bayat Zinc-efficientcultivar under Zinc deficiency conditions was significantly more than that of other cultivars. In conclusion, the results of the current study demonstrated the enhanced activity of the antioxidant enzymes in Bread wheat under zinc deficiency conditions.
