- 摘要:
- 以白头翁和兴安白头翁种子为试材,研究了植物生长激素、温度、光照和浸种等处理方法对2种白头翁种子萌发的影响。结果表明:5 mg/L NAA和100 mg/L GA3处理的白头翁种子萌发率显著高于对照(P<0.05);10和50 mg/L GA3处理的兴安白头翁其发芽率和发芽势均显著高于对照(P<0.05)。2种白头翁种子的萌发率和发芽势均随着温度的升高而明显增高,适宜的发芽温度为25~30℃。延长光照和浸种时间处理可以明显促进2种白头翁种子的萌发率和发芽势。
- Abstract:
- Taking the seed of Pulsatilla chinensis and Pulsatilla dahurica as test materials,the effect of different treatment methods plant growth hormones,temperature,illumination and soaking on seed germination were studied.The results showed that the germination rate of the seed of Pulsatilla chinensis was significantly enhanced after treated with 5 mg/L NAA and 100 mg/L GA3.The germination rate and germination energy of the seed of Pulsatilla dahurica were significantly higher than CK after treated with 10 and 50 mg/L GA3.The germination rate of the two seeds were enhanced as the temperature increased,and the optimum temperature was 25~30℃.In addition,the germination rate of the two seeds were also raised after enhanced the treatments of illumination and soaking.
