摘　　要：探讨豌豆幼苗对Na2CO3溶液胁迫的生理变化，为豌豆的种植和栽培提供线索。使用不同Na2CO3溶液梯度处理豌豆幼苗8d，分析幼苗叶片叶绿素含量、丙二醛（MDA）含量、抗氧化酶活性生理指标的变化等。研究结果显示，豌豆幼苗能抵抗25—50mmol·L^-1Na2CO3溶液胁迫，具有一定程度的抗盐性。Objective：The effects of seedling physiological indexes in Pisum sativum L. treated by Na2CO3 solution were explored to provide index for its planting and cultivation. Method ： Pisum sativum L. seedling for 8 day under salt stress gradient Na2CO3 were analyzed about chlorophyll content, MDA content, antioxidant enzyme activity changes of the physiological indexes. Conclusion：The results showed that pea seedlings can withstand 25 -50 mmol · L^-1Na2CO3 solution stress. In a word,Pisum sativum L. resists salt stress in a certain degree.
