Karyotype Analysis of Paeonia ostii
|
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.
