通过室内水培试验，探讨了NaCl 胁迫对水稻苗期生长及离子吸收与转运的影响。结果表明，NaCl胁迫促使株高下降和生物量积累减少，且随着NaCl浓度增加，株高和生物量积累降幅增大，但长白9号降幅均较小。较低浓度NaCl胁迫下，各材料叶片中Na+浓度增幅显著小于根和茎部，但随浓度增加，越光叶片Na+浓度增幅大于根和茎部。长白9号叶片和根部K+/Na+显著高于越光。 NaCl胁迫降低了各器官Ca2+吸收量，且随浓度增大，Ca2+吸收量降低。生长叶对NaCl胁迫响应最敏感，下降幅度最大，成熟叶次之。根的Ca2+的降幅最小。从材料上看，长白9号各器官降幅均低于越光。

Effect of NaCl stress on seedling growth and ion absorbing and transportation were researched by test of indoor hydroponic. The result indicated that NaCl stress can made plant height short and biomass accumulation reduced, and decrease amplitude was increase with increasing contents, but Changbai-9 had a less decrease. Under the condition of low concentration NaCl stress, growth of Na+ concentration in leaf significantly less than its in root and stem among experiment material except Koshihikari. K+/Na+of leaf and root in Changbai-9 significantly higher than Koshihikari`s. NaCl stress can reduce Ca2+of various organs, and absorptive amount of Ca2+reduce with concentration increased. Growth leaf was the most vulnerable to NaCl stress and had biggest decline, closely followed by mature leaf, the smallest in leaf. decreasing amplitude of various organs in Changbai-9 were below than Koshihikari`s.
