This study was conducted to determine the effects of some priming treatments on seed germination properties, grain yield and several agromorphological characteristics of bread wheat. Two commonly grown bread wheat varieties, namely Adana-99 and Pandas, were selected for experimentation conducted during the 2007–08 and 2008-09 growing periods. | Turkish Journal of Agriculture and Forestry Turk J Agric For (2015) 39: 1005-1013 © TÜBİTAK doi: Research Article Effects of different priming applications on seed germination and some agromorphological characteristics of bread wheat (Triticum aestivum L.) 1,2, , 3, 4 2 Faruk TOKLU * **, Faheem Shehzad BALOCH ***, Tolga KARAKÖY , Hakan ÖZKAN 1 Vocational School of Kozan, Çukurova University, Adana, Turkey 2 Department of Field Crops, Faculty of Agriculture, Çukurova University, Adana, Turkey 3 Department of Agricultural Genetic Engineering, Faculty of Agricultural Sciences and Technology, Niğde University, Niğde, Turkey 4 Vocational School of Sivas, Cumhuriyet University, Sivas, Turkey Received: Accepted/Published Online: Printed: Abstract: This study was conducted to determine the effects of some priming treatments on seed germination properties, grain yield, and several agromorphological characteristics of bread wheat. Two commonly grown bread wheat varieties, namely Adana-99 and Pandas, were selected for experimentation conducted during the 2007–08 and 2008–09 growing periods. The seeds of the Adana-99 and Pandas wheat varieties were primed with the following: (1) distilled water, (2) 100 ppm indole-3-acetic acid (IAA), (3) potassium chloride (KCl), (4) 1% potassium dihydrogen phosphate (KH2PO4), (5) 10% polyethylene glycol (PEG-6000), or (6) gibberellic acid (GA3, used only for field experiments). Nonprimed seeds were used as the control group. First 1000 mL of priming media was prepared for each priming treatment, and seeds of both varieties were rinsed in the solution for 12 h at room temperature. Germination percentage at two different temperatures (10 °C and 20 °C), coleoptile length, seedling emergence percentage, and seedling growth rate were evaluated under laboratory conditions. Primed seeds of both varieties were sown on two different dates .
