Salt stress as a major adverse factor can lower germination, imbalance of the cellular ions resulting in ion toxicity, reduction in enzymatic and photo- synthetic efficiency and cause other physiological disorders and ultimately lower crop productivity in salinity zones. Zinc (Zn) is an important essential micro- element for wheat. In the present study the role of Zn (low 199 ng Zn seed-1 and high 595 ng Zn seed-1) under different levels (0, 50, 100 and 150 mM) of NaCl with three replications were determined during 2014 in the research laboratory of the Faculty of Agriculture, University of Maragheh in Maragheh state in Iran. The results of this study indicate, that salinity decreased the shoot, seminal root and seedling length and also shoot, seminal root and seedling dry matter weight, seed germination and seedling vigor index. Seed Zn content significantly (P<0.01) increased the shoot length (15.5%), seedling length (17%), final germination percentage (10.1%) and seedling vigor index (26%).
