摘　　要：以新铁炮百合朱丽叶当年采收种子为材料,对种子分别进行室温浸泡3 d,室温浸泡5 d,4℃浸泡5 d和不浸泡预处理后,再分别进行无菌播种、培养皿播种和穴盘播种,研究促进朱丽叶种子发芽的最佳方式。结果表明,以无菌的方式播种,4℃浸泡5 d并剥皮处理,第10天即可发芽,第45天发芽率最高(97.78%),并且幼苗长势也较其他处理健壮;以培养皿的方式播种,室温浸泡3 d或5 d且不剥皮处理的方式优于其他各处理,第15天开始发芽,第50天发芽率最高(83%);田园土∶锯末为3∶1配制的播种基质并不适合朱丽叶种子的萌发。To explore the best way for Lilium formolongi Julius seeds germination, newly collected seeds treated preliminarily in different methods were used. After preliminary treatment of lower temperature, soak time or removal of seed coat, seeds of Julius were sowed in sterile bottles, petri dishes and soil substrate. The result showed that if one sowed Julius seeds in a sterile manner, the highest germination speed（ten days）and germination rate（97.78%）were gained after seeds were soaked in 4 ℃ for five days and the seed coats were removed. If one sowed Julius seeds in petri dishes, the highest germination speed（fifteen days）and germination rate（83%）were gained after seeds were soaked in room temperature for three or five days and the seed coats were not removed. Sowing substrate of garden soil with sawdust（3∶1）is not suitable for Julius seeds germination.
