| 摘 要： | 对高冰草种子在4种盐分NaCl、Na2SO4、Na2CO3、NaHCO3的8个不同浓度(0.2%、0.4%、0.6%、0.8%、1.0%、1.2%、1.4%、1.6%)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:高冰草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。

| Abstract: | The germination percentage,embryonic root and seedling length of tall wheatgrass(Thinopyrum ponticum) seeds were tested.NaCl,Na2SO4,Na2CO3 and NaHCO3 with eight concentrations(0.2%,0.4%,0.6%,0.8%,1.0%,1.2%,1.4% and 1.6%) were used as the stress factors.The result showed that the germination percentage of tall wheatgrass decreased with the increasing of salt concentration.The order of salt resistance was as follows:Na2SO4>NaCl>NaHCO3>Na2CO3. |
