| 摘 要： | 采用常规压片法对石竹(Dianthus chinensis L.)花粉母细胞减数分裂进行了细胞学观察。结果表明,减数分裂过程中存在二价体提前分离、赤道板外染色体、落后染色体、染色体不均等分离等异常现象,各时期的畸形率都低于3%,石竹的减数分裂过程基本正常,石竹染色体数目2n=2x=30。 |
| 关 键 词： | 石竹 花粉 染色体 细胞学 |

| Abstract: | The meiotic process of pollen mother cells in Dianthus chinensis L. was observed by traditional squash method. The results showed that abnormal phenomena, such as bivalent separated in advance, chromosomes scattered outside equatorial plate, lagging chromosomes and chromosome uneven separation, occurred in the process of meiosis. The meiotic process of D. chinensis was generally normal due to abnormality rate at different development stages below 3%. The chromosome number of D. chinensis was 2n=2x=30. |
