摘　　要：对朝鲜碱茅种子在4种盐分NaCl、Na2SO4、Na2CO3、NaHCO3的7个不同浓度(0.3%、0.5%、0.7%、0.9%、1.1%、1.3%、1.5%)的胁迫下进行发芽试验,分别观测其发芽情况,胚根和幼苗的生长.结果表明:朝鲜碱茅种子的发芽率随盐分浓度的增加而降低.其耐盐顺序为Na2SO4>NaCl>NaHCO3>Na2CO3.The germination percentage,the growth of embryonic root and seedling Puccinellia chinampoensisi were tested,and NaCl,Na 2 SO 4,Na 2 CO 3 and NaHCO 3 with seven concentrations（0.3%,0.5%,0.7%,0.9%,1.1%,1.3% and 1.5%） were used as the stress factors.The results showed that the germination percentage decreased with the increasing of salt concentration.The order of salt resistance was as follows：Na 2 SO 4〉 NaCl 〉NaHCO 3 〉Na 2 CO 3.
