1 Nucleolus disappeared, but some plants in the early diakinesis nucleolus remains high.

2 At diakinesis or metaphase in the first division of meioses, 29 divalents appeared.

3 Diakinesis The last stage of the PROPHASE in the first division of MEIOSIS.

4 Diakinesis bivalents end of some of the homologous chromosomes together only at the end.

5 Prophase may be divided into successive stages termed leptotene, zygotene, pachytene, diplotene, and diakinesis .

6 The analysis of chromosome behavior in miosis and frequency of bivalent chiasma at diakinesis of pollen mother cells of F1 hybrid plants, and the affinity extent were reported in this paper.

7 Chiasmata are seen during this stage, and by the end of diakinesis the nucleoli and nuclear membrane have disappeared.

8 The nucleus in shrinking cytoplasm of microspore mother cell enters into diakinesis stage .16.

9 The results were as follows:the meiosis in pollen mother cells of radish simultaneous cytokinesis and chromosomes could be identified as rod or ring bivalents in diakinesis except for 3% abnormal.
