The experiments have four different concentrations of salt stress，the guide line of morphologic in the germination period and seed period were studied with four rice of Ⅱyou 7，Mianjing 147，Hexi 22-2 and Hexi 22. The results indicated that varieties of rice were significant of difference sensitive to salt stress. Germen was more restrained than root with 150mmol/L NaCl concentration. The growth of seeding was restrained with different concentrations of salt stress，and aboveground was less tolerance than underground portion.
