microsporocyte

microsporocyte

1. primary microsporocyte

初级小孢子母细胞

2. The results showed that the wholly developmental process could be tentatively divided into four stages, i.e. microsporocyte formation, microsporocyte meiosis, pollen formation, and pollen abortion.

在这一过程中绒毡层发育既表现过早解体，又表现肥大生长、延迟退化的现象。同一枚花药中4个花粉囊的发育也存在明显的先后次序。

3. Ubisch bodies and lipid bodies are found in the glandular tapetums. In meiosis of microsporocyte, cytokinesisis is a simultaneous type, which produces an isobilateral tetrad.

小孢子母细胞减数分裂胞质分裂为同时型,产生正四面体型四分体。

4. During the microsporocyte meiosis process, the cytoplasm division could be attributed to the simultaneous type, while the microsporocyte tetrad belongs to tetrahedral type.

小孢子母细胞减数分裂过程中的胞质分裂为同时型，小孢子4分体为四面体形；

5. Many endoplasmic reticulums and plastids are present at microsporocyte stage.

小孢子母细胞时期内质网和质体较多；

6. The tapetum is of glandular type.Cytokinesis in the microsporocyte meiosis is successive type and tetrads are isobilateral.

小孢子母细胞经减数分裂形成左右对称形四分体，胞质分裂为连续型，成熟花粉粒为2-细胞型；

7. secondary microsporocyte

次级小孢子母细胞

8. The main results were as follows: “Cytoplasm reorganization” occurred during the meiosis of microsporocyte, resulting in the decrease of ribosome and regular changes of plastids and mitochondria.

结果表明，小孢子母细胞减数分裂期间，细胞质发生了“细胞质改组”现象，主要表现在核糖体的减少，质体、线粒体的结构发生了规律性的变化。

9. pollen mother cell;microsporocyte

花粉母细胞

10. The endothecium and epidermis persist.Cytokinesis in the microsporocyte meiosis is simultaneous type and the microspore teads are tetrahedral.

药室内壁纤维状加厚,药壁表皮宿存.小孢子母细胞减数分裂为同时型;
