Abstract
以芦笋种子NY2037为实验材料,选取NaCl、Na2SO4、NaHCO3、Na2CO34种盐碱胁迫,分别设置盐碱浓度0(CK)、25mmol/L、50mmol/L、75mmol/L、100mmol/L、125mmol/L、150mmol/L、175mmol/L、200mmol/L共9个处理,研究不同盐碱胁迫对芦笋种子发芽率的影响.结果表明:芦笋种子具有较强的耐盐碱胁迫能力;低浓度的中性盐处理有利于芦笋种子的萌发,发芽率随着盐碱溶液浓度的增高均降低;对发芽率的抑制作用依次为Na2 CO3>Na2 SO4>NaCl>NaHCO3;复萌试验表明,盐碱胁迫下,芦笋种子保持了较高的萌发潜力.
