| 摘 要： | 本文采用喜树顶芽及新生愈伤组织为试验材料,进行染色体制作方法的研究 并就喜树染色体核型进行了分析,其结果显示:喜树体细胞染色体为2n=44,其中正中部着丝点染色体(M)为1对,中部着丝点染色体(m)为16对,近中部着丝点染色体(sm)为1对,端部着丝点(T)为4对,其核型公式为K(2n)=44=2M+32m+2sm+8T,核型属于"2B"型

| Abstract: | The article studies a new method of making chromosomes by callus and bud, and analyses the karyotype of Campotheca acuminata Decne. The results demonstrated the chromosome amount to 44. The karyotype formula is K_((2n))=44=2M+32m+2sm+8T. Among them, 1pair is median point (M),16 pairs are median region (m),1 pair is submedian region (sm), 4 pairs are terminal point(T),belonging to"2B" type. |
