| 摘 要： | 研究光照、温度、水分和土壤盐分等因子对苦豆子(Sophora alopecuroides L.)种子萌发的影响。结果表明:在持续光照、持续黑暗和16 h光照/8 h黑暗下种子萌发最适宜的温度为25℃;在16~8 h光暗交替下,25℃/16℃昼夜变温发芽率最高;种子萌发对光照不敏感;种子萌发最适土壤含水量为8%~13%;种子发芽期对NaCl的耐受浓度为1.2%。

| Abstract: | The effects of illumination,temperature,soil water and salt contents on the seed germination and seeding growth of Sophora alopecuroides L.was studied.The results show that the optimal tem-perature for seed germination was 25℃ under sustained illumination,sustained dark,or 16 h illumination/8 h dark.;the highest germination rate was occurred for the treatments of 25℃(daytime)/16℃(night) under 16 h illumination/8 h dark.The seed germination and seeding growth were not sensitive to the illumination.The optimal soil water content was 8~13% and the highest NaCl tolerance concentration was 1.2%for seed germination. |
