Abstract
Seed priming is one of the methods to improve function that can be taken to promote early growth of the plant and to overcome environmental problems and fainaly, the optimal deployment seedling lead to high-yield in plants. In order to identify the effects of priming on enzyme and morphological characteristics in terms of water stress on wheat, this study was performed based on randomized complete block design with 15 treatments and 3 replications in Maragheh University in 2014. Factors examined include irrigation levels (30, 60 and 90% of field capacity) and hormonal priming (dry seed, Hydropriming, salicylic acid, gibberellic acid, paclobutrazol). Results showed that drought stress significantly reduced leaf area, root dry weight, chlorophyll, malondialdehyde, hydrogen peroxide, proline, superoxide dismutase, catalase and ascorbate peroxidase. While the use of hormonal priming significantly increased chlorophyll, MDA, proline, superoxide dismutase and ascorbate peroxidase under drought stress treatments. The composition Paclobutrazol priming and 30% of field capacity increased the enzyme activity of superoxide dismutase, ascorbate peroxidase and catalase, respectively, 2.05, 0.12 and 0.046 units. Hormonal priming had positive effect on enzyme activity. Paclobutrazol treatment was more effective than other treatments.
