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.
