用两种钠盐不同浓度对藜种子进行了发芽试验，研究了两种钠盐胁迫对藜种子萌发的影响，探讨其耐盐性。结果表明：两种钠盐胁迫对藜种子的萌发有抑制作用，随着盐浓度的增加，种子的发芽率、发芽势、发芽指数、活力指数均呈显著下降趋势（p〈0．01），盐浓度过高会抑制种子萌发，NaHCO3浓度250mmol／L、Na2CO3浓度200mmol／L时，藜种子无发芽能力。两种钠盐对藜种子发芽后的胚根及胚芽生长的抑制作用表现不同，NaHCO3对藜种子的抑制：胚根〉胚芽，Na2CO3对种子的抑制：胚根〈胚芽。
用兩種鈉鹽不同濃度對藜種子進行瞭髮芽試驗，研究瞭兩種鈉鹽脅迫對藜種子萌髮的影響，探討其耐鹽性。結果錶明：兩種鈉鹽脅迫對藜種子的萌髮有抑製作用，隨著鹽濃度的增加，種子的髮芽率、髮芽勢、髮芽指數、活力指數均呈顯著下降趨勢（p〈0．01），鹽濃度過高會抑製種子萌髮，NaHCO3濃度250mmol／L、Na2CO3濃度200mmol／L時，藜種子無髮芽能力。兩種鈉鹽對藜種子髮芽後的胚根及胚芽生長的抑製作用錶現不同，NaHCO3對藜種子的抑製：胚根〉胚芽，Na2CO3對種子的抑製：胚根〈胚芽。

The research used two different sodium salt with different concentrations acting on Chenopodium album L. and though sprout experiment to study the influence of two sodium salt stress to Chenopodium album L. seeds sprouting as well as to analyse its salt tolerance. The results showed that with the increase of the concentration of two salt, germination rate, germination potential, germination index and vigor index had a significant decrease and an overtopped salt concentration （NaHCO3 at 250 mmol/L, Na2CO3 at 200 mmol/L） could inhibit the seeds sprout completely. The inhibition effect of two sodium salt to radicle and germ of sprouted Chenopodium album L. was different. The inhibition effect of NaHCO3 was root 〉 bud, the inhibition effect of Na2CO3 was root 〈 bud.
