| 摘 要： | 本文对国产7种甘草属植物的核型进行了研究，其结果为：乌拉尔甘草2n＝16＝
6m+10sm；黄甘草2n＝16=8m+6sm十2st；光果甘草2n＝16=14m+2sm；胀果甘
草2n＝16＝6m十10sm；粗毛甘草2n=16=12m十4sm；云南甘草20＝16=12m十
4sm；刺果甘草2n＝16＝12m十4sm。基于对现有资料的分析，确认该属的染色体基数为
x=8， 且核型对称性程度较高。 通过对不同种核型进行比较，发现刺果甘草是本文所研究
7个种中最原始的，而黄甘草的进化程度相对较高。

| Abstract: | Seven species of Glycyrrhiza in China are karyologically analyzed in this pa-
per. The results are as follows: G. uralensis Fisch. 2n=16=6m+10sm; G. eurycarpa P.C.
Li 2n=16=8m+6sm+2st; G. glabra L. 2n=16=14m+2sm; G. inflata Bat. 2n=16=6m+10
sm; G. aspera Pall. 2n=16=12m+4sm; G. yunnanensis Cheng f. et L. K. Tai ex P. C. Li 2n
=16=12m+4sm; G. pallidiflora Maxim. 2n=16=12m+4sm.
From this work and the previous reports, it is presumed that the basic chromosome num-
ber of Glycyrrhiza is x=8. Based on the characters of karyotype so far realed, the authors
consider that the genus Glycyrrhiza is a relatively primitive group in Leguminosae and G.
pallidiflora is the most primitive one among the species dealt with in this paper, and G. eurycar-pa is the most advanced one. |
