It is not clear whether the abortion of the tetrads stimulates proliferation of the tapetal cells or the proliferating tapetum actually interferes with microspore development thereby causing degeneration .

由于 绒 毡 层 细胞异常膨大，挤压四分体，四分体不分离产生 四 分小孢子，从而不能形成正常的花粉粒而导致败育。

The mainly cytological reason resulting the abortion is the abnormal function of the tapetal cells .

导致 雄性不育主要的细胞学原因是 绒 毡 层 细胞 结构、功能的失常。

On the contrary the GA 1 + 4 localized in tapetal cells gradually decreased with the anther development .

绒 毡 层 细胞质 和 细胞核内 GA1+4的分布 数量逐渐减少。

Although tapetal cells developed normally meiotic behavior of chromosomes in pollen mother cells ( PMC ) were abnormal leading to the degeneration of microspores ;

绒 毡 层 细胞虽发育正常，但小孢子母细胞减数分裂行为异常；这些都导致小孢子退化。

The haploid pollen cells develop in the tapetal zone from spore mother cells .

单倍体花粉 细胞由 绒 毡 层 提供 营养 发育。

The tapetal cells of CMS line A4 enlarged abnormally at meiotic phase pressing microsporocyte seriously .

不育系A4在减数分裂期即表现出异常， 绒 毡 层异常肥大；

In tetrad stage the structures of tapetal cells begin to dissociate .

四分体时期， 绒 毡 层 细胞内部结构开始解体。

The results revealed that the tapetal cells of the male sterile A2 developed abnormally at tetrad stage and they became vacuolated and numerous small vacuoles are present .

结果表明：不育系A2的 绒 毡 层 细胞在四分体时期出现异常，小液泡增多，至单核期汇合形成大液泡， 绒 毡 层 细胞异常膨大；

When microspore mother cell ( MMC ) preparing meiosis calcium precipitates appeared in the cytoplasm of tapetal cells and callus wall surrounding MMC .

当花粉母 细胞进行减数分裂时，花药中的钙颗粒 进一步 增加， 尤其是在小孢子母细胞的 胼胝质壁中。

The chromatin of tapetal cell has a period of becoming condensed and then spreading accompanying the meiosis of the microspore mother cells which will affect the entering of nutrient into the inner part of microsporangium .

绒 毡 层细胞的染色质伴随着小孢子母 细胞减数分裂有一个浓缩和伸展的时期，这个时期影响营养物质向小孢子囊内部转运。

Tapetal cells always contain rich DNA RNA and protein .

绒 毡 层 细胞始终含丰富的DNA、RNA、蛋白质。

The tapetal cells of fertile anther began to synthesis abundant lipid material during microspore development .

在可育花药中， 绒 毡 层 细胞在小孢子发育 后期已 显示 出 退化迹象， 同时在 细胞中开始积累脂类物质。
