摘要：

以小麦烟农19和克旱16为材料，研究NaCl胁迫下对小麦不同品种种子萌发与幼苗生长的影响。结果表明：在NaCl胁迫下，小麦两个品种的发芽率、苗高、根长、苗重、根重、根数等均随浓度的增加呈下降趋势，其中NaCl胁迫对苗重与根重的影响较大，依品种不同在浓度25mmol/L和50mmol/L时显著低于对照。小麦两个品种对NaCl的耐受性不同，烟农19较克旱16耐NaCl胁迫。

Abstract:

The wheat Yannong No.19 and Kehan No. 16 were used as the experimental materials to study the effect on seed germination and seedling growth under the condition of the NaCl stresses. The results showed that the germination rate, seedling height, root length, seedling weight, root weight and root number of two varieties in wheat pointed a significant downward trend as the NaCl concentration increases. Seedling weight and root weight was affected greater than other characters by NaCl stress and was significantly lower than the control when the NaCl concentration was 25mmol/L and 50mmol/L according to different varieties. Two varieties of wheat have shown varying degrees of tolerance to NaCl. Yannong No.19 tolerates NaCl better than Kehan No. 16.
