摘 要: | 目的]研究滇重楼种子萌发的最适温度条件。方法]采用不同的温度条件(15、20、25℃)对滇重楼种子进行培养,观测其对种子萌发的影响。结果]20℃恒温条件下,培养55 d后,种子开始萌发,100 d后萌发率为98.89%,根的生长情况也最好;15和25℃条件下培养的种子,萌发率低,萌发不整齐,根生长缓慢。结论]20℃恒温是滇重楼种子萌发及根系生长最适宜的温度条件。

Abstract: | Objective] The research aimed to study the optimum temperature conditions of Paris polyphylla seeds germination. Method]The seeds were cultured under different temperature conditions (15, 20, 25℃),its effects on seed germination were studied. Result]In 20℃ con-stant temperature conditions, the seeds began to germinate after culturing 55 days,the germination rate of seeds was 98. 89%,the growth of root was the best after culturing 100 days. In 15 ℃and 25 ℃ temperature condition, seeds had low germination rate, germination was not neat, root growth was slow. Conclusion]20℃ constant temperature treatment is the best condition for seed germination and root growth of Paris polyphylla. |
