为筛选出适于重楼发芽种子出苗生长的最佳方法,以重楼为试材,首先将重楼发芽种子进行0、500、1 000、1 500、2 000、2 500lx光照处理,将重楼发芽种子进行子叶转绿发育、剥壳、断主根方法处理,研究了光照子叶转绿发育、剥壳、断主根协同作用对重楼种子播种出苗的影响.结果表明:发芽种子经过2 500lx强度光照照射最为适宜,华重楼、滇重楼子叶最低转绿发育率分别达到91.03％和90.15％以上,转绿发育所需天数分别在8.46、8.21d以内;转绿、剥壳和转绿、剥壳、断主根提高了出苗率并缩短了出苗时间,华重楼、滇重楼出苗率达到91.32％、87.64％以上,出苗时间也分别缩短10.32、11.06d以内;转绿、剥壳和转绿、剥壳、断主根的株高、叶面积、根茎鲜质量等重要农艺性状的各项指标均表现最好,其中转绿、剥壳、断主根达最大值,株高、叶面积、根茎鲜质量分别为4.76cm、5.56cm2、0.60g.%In order to select the best method for Paris polyphyllaseedling,taking Paris polyphylla as test material.First,to research the different light intensity on the virescent cotyledons development, germinated seed of the Paris polyphylla were treated using lighting for 0,500,1 000,2 000,2 500lx. Second,to research the synergistic effect on sowing and seedling,germinated seed of the Paris polyphylla were treated using lighting,shelling and root cutting.The results showed that after 2 500lx light intensity,the virescent cotyledons rate of the Paris polyphylla Smith var.Chinensis of the germinated seeds were above 91.03％in 8.46days,the virescent cotyledons rate of the Paris polyphylla var.Yunnanensis of the germinated seeds were above 90.15％ in 8.21days.After lighting,shelling treatment and lighting, shelling,root cutting treatment,emergence rate and time of the Paris polyphylla Smith var.Chinensis and the Paris polyphylla var.Yunnanensis were above 91.32％ and 87.64％,in 8.46days and 8.21days, respectively.Plant height,leaf area,fresh mass of rhizome and other important agronomic traits of the indicators of lighting,shelling treatment and lighting,shelling,root cutting treatment were both the best, lighting,shelling,root cutting treatment was max in plant height,leaf area,fresh mass of rhizome,which were4.76cm,5.56cm2,0.60g,respectively.
