摘要
玉竹(Polygonatum odoratum(Mill))是百合科黄精属的一种,是传统的中草药。玉竹广布于我国东北、华北、华东和西南各省,以及欧亚大陆温带地区。玉竹的细胞学研究较少,多见于染色体数目报道。本文研究了不同地理分布区玉竹的染色体数目及其核型,初步探讨了它们的演化关系,为黄精属细胞地理学研究提供一些新的资料。
Polygonatum odoratum is widely distributed in subtropical and temperate areas of China and temperate areas of Eurasia continent. In this paper, the karyotype and number of chromosomes of P. odoratum in different distribution areas of China are reported to reveal the evolutionary relationships among specimens from different areas. It provides new material for the cytogeographical research of Polygonayum.
