| 摘 要： | 报道了芦荟属14种2变种植物的核型，实验结果表明所研究种类的体细胞染色体基数均为X=7，二倍体，由4对长染色体和3对短染色体组成。根据Stebbins（1971）的核型分类标准，Aloeaffinis Berger等3种芦荟的核型为“3B”型，Aloe graciliflora Groenewald等3种芦荟的核型为“4B”型，A．mitriformis Mill等3种2变种芦荟的核型为“3C”型，A．saponaria（Air．）Haw等5种芦荟的核型为“4c”型。其中有6种1变种芦荟的核型为首次报道。另外，还对芦荟的系统分类进行了讨论。 |

| Abstract: | The karyotypes of 14 species and 2 varieties of Aloe L.were reported.The results of karyotype analysis are as follows: all species studied here in the genera have a single basic chromosome number(x=7),diploidy and a large strongly bimodal karyotype always comprising three short chromosomes and four much longer ones in the haploid set.According to Stebbins'criterion for classification of chromosome karyotype,the karyotypes of the species belong to '3B','4B','3C' or '4C'.Karyotypes of 6 species and 1 variety were firstly reported.Otherwise,we had discussed its systematical implication in Aloe L. |
