The present study was conducted to enhance the germination and seedling growth of wheat (Triticum aestivum L.) CV. Zarin seeds using different osmopriming treatments. Seeds were osmoprimed with Polyethylene Glycol (PEG 8000), KNO3 solutions for 12 h. The osmotic potential of the all solutions were -0.3, -0.6 and -0.9 MPa. During osmopriming operation all solutions aerated with aquarium pump. The control seeds were not treated. Osmopriming treatments improved germination and seedling vigor than that control.
