In this study, the effect of seeds priming (2.5 and 5 mM) and coating (1.5, 2.5 and 5 g Zn/kg seeds) on early growth stages of two wheat varieties showing difference for their seed Zn contents (Imam with average 29 mg/kg Zn and Altındane 25.5 mg/kg Zn) on germination and seedling growth parameters were determined under controlled-growth chamber conditions 20-25°C and 70% RH. In each treatment, 25 seeds were placed into Petri dishes to determine seed germination and sown into pots containing 700 g alluvial soil with low Zn content to monitor seedling growth for 21 days using three replications. The results revealed that seed priming with Zn, particularly high dose (5 mM) had relatively positive impact on seed germination, mean germination time and seedling growth parameters when compared with low Zn dose (2.5 mM) and hydropriming in both two wheat varieties. Seed coating with Zn, particularly with low Zn concentration (1.5 g Zn/kg seeds) and in Altındane with less Zn content, has shown good respond and improved seed germination parameters in comparison with untreated seeds for both wheat varieties. In conclusion, Zn seed priming and coating had more evident effects on germination and seedling growth parameters in variety with low Zn content compared with high one. The lowest concentration of seed coated with Zn of 1.5 g Zn/kg seeds had positive impact on wheat seedlings growth as well as it has low cost and safe to prevent of environment pollution.
