The study utilized six maize hybrids as materials and different NaCl concentrations solutions to simulate salt stress environment, researching the trait differences of maize germination, specifically including plantheight, leaf fresh weight, root fresh weight, leaf dry weight, root dry weight, leaf moisture content, moisture content root, root to shoot ratio, germination rate etc. It also explored the correlation between different NaCl solution concentration and the each trait of maize germination.The results showed that the trait differences of the different hybrid combinations reached the level of 0.05 or 0.01 except the leaf moisture content and root moisture content at germination stage. As a result , these indexes can be used as indicators of the salt tolerance maize about screening, identification . NaCl concentration was significantly correlated with each trait, excluding root shoot ratio Increases with increasing of NaCl concentration, the other indicators decreased with the increasing of NaCl concentration.
