目的通过对移植试管植株与种子植株植物学性状的对比分析,为优质北柴胡快速繁育方法的建立和推广提供科学依据。方法选取有效药用成分高、遗传稳定性好的北柴胡栽培类型进行快速繁殖,比较移植试管植株与种子植株的植物学性状。结果北柴胡移植试管植株在分蘖数、分枝数、有效花序数以及根质量等方面明显优于种子植株。结论通过快速繁殖和试管苗的规模化种植,在保持北柴胡优良性状的同时,可以收获多于种子植株的根器官和种子。
OBJECTIVE: To provide a scientific basis for establishing and popularizing the rapid breeding method of high quality Bupleurum by comparing the botanical characters of the transplanted test tube plant and the seed plant. Methods Bupleurum chinense with high medicinal composition and good genetic stability was selected for rapid propagation. The botanical characteristics of transplanted in vitro and in vitro plants were compared. Results The transplanted test tube plants of Bupleurum chinense were obviously better than the seed plants in terms of tiller number, number of branches, number of effective inflorescence and root quality. Conclusion Through rapid propagation and large-scale planting of test-tube seedlings, root organs and seeds of more than seed plants can be harvested while maintaining the excellent characters of Bupleurum chinense.
