| 英文摘要 | A comparative study of meiosis of pollen mother cells in Manglietia patungensis Hu and its closely related species M yuyuanensis Law was carried out. These two species had the same chromosome number of 2n=38 and the same karyotype, but their chromosomal behaviors in meiosis were different. In M patungensis, the typical chromosome configurations observed at metaphase were 2n=0.30IV+18.33II+0.15I, whereas those in M yuyuanensis were 2n=19II, indicating that some chromosomes in M patungensis might have undergone inversion and that some chromosome components were possibly paracentric inversion heterozygotes. The abnormal rate of chromosomal behaviors at anaphase I and II was different in the two species. At anaphase II, 8.8% cells were observed with lagging chromosomes which in each cell did not exceed two in M yuyuanensis, but in M. patungensis, 29.2% cells were observed with lagging chromosomes which could reach 11 in each cell. Additionally, broken chromosomes were observed in M patungensis. The above results indicate that the abnormal rate of chromosomal behaviors in the meiosis of M patungensis was higher than that in M yuyuanensis. The abnormal behaviors of the chromosomes in meiosis observed in M patungensis may have affected the development of pollen grains in this species. |
