Karyotype Analysis of Aloe Vera L.Var.Chinensis(Haw)Berger

Wang Yongzhong,Fan Pan,Shen Shuyu (Department of biology,Anhui University,Hefei 230039)  
Aloe Vera L.Var.Chinensis (Haw)Berger belongs to Liliaceae Aloe(genus).In the paper, It is taken as experimental material and its chromosome is observed by routine root tip method. The results shows that the chromosome number of Aloe Vera L.Var.Chinensis(Haw)Berger is 2n=14 and the karyotype is K(2n)=6st+8sm by Levan's crierion for classification of chromosome karyotype.There are not matacentric and acrocentric chromosomes ,wtheout any satallite chromosome being observed ,The chromosome constitution of Aloe Vera L.Var.Chinensis(Haw)Berger is four long and three short, which is obviously different from that of Aloe Vera L.There are three long one intermediate and three short in the latter. Whther Aloe Vera L.Var.Chinesis(Hew)Berger belongs to a variety of Aloe Vera L.is still to be identified by methods of morphoanatomy, analysis of chromosome banding pattern, comparing with homology extent of DNA nucleotide by technology of molecular biology, and so on.
