THE KARYOTYPE ANALYSIS OF THE TRADITONAL CHINESE MEDICINAL HERB COIX LACHRYMA-JOBI L / 西安交通大学学报(医学版)

ABSTRACT

The counts of the chromosome and karyotypeanalysis of coix lachryma-jobi L. (a traditional Chi-nese medicinal herb) are represented in this pa-per. The results show that the number of the chro-mosome of coix lachryma-jobi L. is 2n=20. All ofthe homologous chromosomes have median kine-tochrores. The absolute length of the chromo-somes tanges from 2. 26～10. 5?m. The relativelength is 7. 19～13. 02%. The karyotype formulais K (2n)=20=20m. These results provide morecritical cytological criteria for identification of Coixlachryma--jobi L. on the chromosomal level. Inaddition, It can be provided the data for studyingof the fraditional Chinese medicinal herbs againstcancer.
