摘　　要：以小紫珠为试材,测定其种子萌发特性及其对环境因子的响应。结果表明,小紫珠种子的最适萌发温度为25℃,40℃浸种24 h发芽率可达88.99%。在25℃,黑暗环境有利于种子萌发,GA 3和6-BA溶液浸种对种子发芽影响较小;小紫珠种子对盐分反应敏感,发芽率随NaCl浓度的升高明显下降,NaCl浓度为300 mmol/L时种子不能萌发。Taking Callicarpa dichotoma as test materials,the seed germination characteristics of Callicarpa dichotoma and its response to environmental factors were determined.The results showed that the seed germination of the most suitable temperature was 25℃and the germination rate of the seeds soaked at 40℃for 24 h was 88.99%.The dark environment was conducive to seed germination at 25℃,GA 3 and 6-BA solution had little effect on seed germination.The seeds of Callicarpa dichotoma were sensitive to salinity and the germination rate decreased with the increase of NaCl concentration.The seeds could not germinate when the concentration of NaCl was 300 mmol/L.
