| 摘 要： | 本文对中医明目要药决明(Cassia tora L.)进行了核型分析。结果表明:决明的染色体数目为2n=26;13对同源染色体中,第5、6、8、10、11对,为近中部着丝点,其余几对均为中部着丝点;第5对长臂具次缢痕,染色体的绝对长度在2.14—3.48微米之间,相对长度在5.90%—9.60%之间。决明的核型公式为:K(2n)=26=16m+8sm+2sm(sc)。本实验为中药决明的药材鉴别在染色体水平上提供了更准确的细胞学依据。

| Abstract: | The karyotype of cassia tora L., a commonly used Chinese medicine capable of improving cyesight, was analyzed in this paper. The results show that the number of the chromosomes of Cassia tora L. is 2n=26. Of pairs homologous chromosomes, the fifth, sixth, eighth, tenth and eleveth pairs are submedian kinetochoral, while others have median kinetorchores. The long arms of the fifth pair have secondary constriction The absolute length of the chromosomes ranges from 2.14 to 3.48 microns. The relative length is from 5.9% to 9.5%. The karyotype of Cassia tora L. can be expressed in the following formula: k (2n) = 26= 16 m+8sm+2sm (sc). These results provide more critical criteria for identiding Cassia tora L. on the chromosomal level. |
