Effects of Different Priming Treatments on Germination and Seedling Growth of Wheat under Drought Stress

Öz

Wheat (Triticum aestivum L.) is a widely cultivated agricultural crop in dry areas. However, drought is one of the most limiting environmental stress factors for crop production in the world's agricultural areas. Seed priming is a physiological technique involving seed hydration and drying to improve metabolic processes before germination. The aim of this study is to determine the effect of four different priming treatments (hormo-priming (gibberellic acid, GA3), redox-priming (hydrogen peroxide, H2O2), osmo-priming (polyethylene glycol, PEG) and thermo-priming (38oC)) on total chlorophyll content (SPAD), relative water content (RWC), specific leaf area (SLA), H2O2 amounts and shoot-root lengths in a local wheat variety (cv. Ekiz). Drought stress significantly decreased seed germination, shoot-root lengths, SLA, SPAD and RWC while increasing H2O2 content. Thermo-priming treatments fully improved the negative effects of drought on chlorophyll amount and germination compared to control plants. However, shoot-root lengths improved only in half level of control plants. While drought stress decreased seed germination by 14%, hormo-priming treatment ensured germination of all seeds. On the contrary of other priming treatments, hormo-priming and osmo-priming treatments increased RWC. Consequently, thermo-priming and hormo-priming treatments found most effective than the other priming treatments in drought stress resistance for cv. Ekiz.
