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.
