Karyotype Analysis and Meiotic Observations of Pollen Mother Cells in Plantago virginica L.
摘要
Abstract
The meiosis of pollen mother cells and karyotype were analyzed for Plantago virginica L. in Wuhan by applying squash method. The result showed that chromosomes of most pollen mother cells were paired as 12 bivalents at diakinesis. The frequency of Lagging chromosome and chromosomal bridge were 2. 93% in pollen mother cells during meiosis. The meiotic division belonged to the simultaneous type,and the stainability of pollen grains was 96. 88%. The chromosome number was 2n=4x=24 and karyotype formula was K(2n) = 4x=24 = 22m+2sm,with karyotype type belonging to "IB".关键词
