In order to evaluate the effect of seawater on germination of experimental rice seeds, a completely randomized design with 4 treatments (control- seawater 15,30 and 45%) was conducted in four replications in 1977 at the Faculty of Agriculture, Guilan University. In this experiment, germination rate, germination percentage, vigor index, fresh and dry weight of root and shoot (pedicel and radical), fresh and dry weight ratio of root to shoot, root and total seedling weight were measured. The results showed that the use of seawater had no significant difference with respect to other traits such as root / shoot dry weight ratio, stem length mean, seed vigor, root to shoot length ratio and other seasons and the use of seawater doesn’t reduce germination percentages. Even the mean comparison showed that seawater use at low treatments increased seedling growth at the germination stage. Overall, the results showed that rice in the germination stage is resistant to seawater consumption and easily tolerates up to 30% of seawater consumption
