摘　　要：以150 mmol/L NaCl胁迫模拟盐渍化土壤中盐分胁迫状况,研究外源氯化钙、葡萄糖对盐胁迫条件下红豆种子萌发的影响。结果表明,不同浓度的氯化钙和葡萄糖均能提高盐胁迫下红小豆种子的发芽势、发芽率、发芽指数、芽长等各指标,其中Ca2+浓度为25 mmol/L时效果最佳。Taking 150 mmol/L NaCl to simulate salt stress condition of saline soil, this paper studied the effects of exogenous calcium chloride and glucose on red bean seed germination under salt stress. The results showed that different concentrations of calcium chloride and glucose both could improve the germination potential, germination rate, germination index, shoot length and other indicators of red bean under salt stress, and best result was rechived when the concentration of Ca^2＋ was 25 mmol/L.
