| 摘 要： | 本文首次报道了杨山牡丹的核型及银染间期细胞核仁数目。结果表明,银染核仁数最多为6个;核型简式为2n=2x=10=6m(3 SAT)+2 sm (1 SAT)+2 s t (2 SAT), 其中第1和第4对染色体短臂上具1个随体,第2和第5对染色体短臂上具1对随体。此外,对国产芍药属二倍体种的随体数目及其杂合性等问题进行了初步讨论。Abstract:In the paper,the karyotype and silver staining of nucleolar numbers of P.ostii Hong et Zhang were reported for the first time.The results show that nucleolar numbers are six at the most and karyotype formula is 2n=2x=10=6m(3 SAT)+2sm(1 SAT)+2st(2 SAT)of P.ostii.There are one satellite on each short arms of the first and fourth chromosomes and two satellites on each short arms of the second and fifth ones respectiuely.In addition,the satellitic numbers and satellitic heterozygosity of diploid species of Paeonia in China are briefly discussed.

| Abstract: | In the paper, the karyotype and silver staining of nuclcolar numbcrs of P. ostii Hong et Zhang were reported for the first time. The results show that nucleolar numbers are six at the most and karyotype formula is 2n=2x=10=6m(3 SAT) 2 sm(1 SAT) 2 st(2 SAT) of P. ostii. There are one satellite on each short arms of the first and fourth chromosomes and two sateilites on each short arms of the second and fifth ones respectiuely. In addition, the satellitic numbers and satellitic heterozygosity of diploid species of Paeonia in China are briefly discussed. |
