摘　　要：主要研究了NaCl、NaHCO3和NaCl+NaHCO3 3种不同盐胁迫对益母草(Leonurus artemisia S.Y.Hu)种子发芽的影响。结果表明,益母草种子随NaCl、NaHCO3浓度的升高,相对发芽率、相对发芽势、相对发芽指数均显著降低,而混合盐溶液中出现低促高抑现象。3种处理抑制作用顺序为NaHCO3>NaCl>NaCl+NaHCO3。益母草种子耐盐大小顺序为NaCl+NaHCO3>NaCl>NaHCO3。Effects of NaCl,NaHCO3 and NaCl＋NaHCO3（salt-alkali）stress on seed germination of Leonurus artemisia S.Y.Hu were studied.The results indicated that the relative germinating percentage,relative germination power and relative germinat-ing index decreased significantly with the increase of NaCl,NaHCO3 concentration;But seed germination rate,germination viability and germination index were promoted by low concentration（under 1 mg / mL） of salt-alkali and inhibited by high concentration（above 1 mg / mL）.The inhibition efficiency was in the order of NaHCO3 NaCl NaCl＋NaHCO3;While the salt-tolerance of L.artimisia seed was NaCl＋NaHCO3 NaCl NaHCO3.
