摘　　要：【目的】白屈菜(Chelidonium majus L.)是多年生草本植物,具有较高观赏价值,目前对白屈菜种子的研究还处于探索阶段,为探究浸种温度、KMnO_(4)消毒浓度和时间以及培养温度和光照对白屈菜种子萌发的影响。【方法】本研究以北华大学校内白屈菜种子为研究对象,对浸种温度进行单因素实验,KMnO_(4)消毒浓度和时间、培养温度和光照进行双因素实验,探究不同处理对白屈菜种子萌发的影响。【结果】15℃水浴浸种下白屈菜的发芽率、发芽势、发芽指数最高,0.3%KMnO_(4)消毒10 min白屈菜种子发芽率最高。25℃全光条件下各项萌发指标最大。【结论】在0.3%KMnO_(4)消毒10 min,15℃水浴浸泡12 h,培养温度25℃,光照12 h/黑暗12 h条件下白屈菜萌发率最高达60%。[Objective]Chelidonium majus L.is a perennial herbaceous plant with high ornamental value.Currently,research on Chelidonium majus L.seeds is still in the exploratory stage.To investigate the effects of soaking temperature,KMnO_(4)disinfection concentration and time,as well as cultivation temperature and light on the germination of Chelidonium majus L.seeds.[Method]This study focuses on the seeds of Chelidonium majus L.at Beihua University.Single factor experiments were conducted on soaking temperature,and dual factor experiments were conducted on KMnO_(4)disinfection concentration and time,cultivation temperature,and light to explore the effects of different treatments on the germination of Chelidonium majus L.seeds.[Results]The germination rate,germination potential,and germination index of white clover seeds soaked in a 15℃water bath were the highest,and the germination rate of white clover seeds disinfected with 0.3%KMnO_(4)for 10 minutes was the highest.The germination indicators are the highest under full light conditions at 25℃.[Conclusion]Under the conditions of 0.3%KMnO_(4)disinfection for 10 minutes,15℃water bath soaking for 12 hours,cultivation temperature of 25℃,and 12 h light/12 h dark conditions,the germination rate of Chelidonium majus L.reached up to 60%.
