type of microsporic tetrads of the simple flower is belong to tetrahedral type and the mature pollen is two-celled with bristles on the surface.───木槿的小孢子母细胞经过减数分裂形成四面体状的四分体，成熟花粉是二细胞型花粉，圆球型，表面有刺毛。
specific pattern had already been formed, when microspores were released from tetrads.───当小孢子从四分体中释放出来，特殊类型的外壁已经形成。
The results showed that the meiosis behavior of pollen mother cell of sterile is normal. Abortion occurred after formation of tetrads.───结果表明，不育株花粉母细胞减数分裂染色体行为未见异常，败育发生在四分小孢子形成之后。
The cytokinesis of the microspore mother cells in meiosis is successive and the microspore tetrads are tetrahedral.───小孢子母细胞减数分裂中的胞质分裂为连续型，四分孢子为四面体型；
The microspore mother cells in meiosis is successive and the microspore tetrads are tetrahedral and bilateral symmetry.───小孢子减数分裂为连续型。四分体呈四面体型和左右对成型。
pollen tetrads in masses, solitary in each anther cell, pollen carriers spatulate, erect.───在群众内四合花粉，单生在内每花药室，花粉搬运工，直立。
Stamens 10, sometimes with spurs or awns, dehiscing by pores, pollen in tetrads, rarely single.───雄蕊10，有时有距或者芒，孔裂，花粉为四分体，很少单体。
pollen yellow, shed in tetrads.───花粉黄，成四分体式脱落。
The tetrads eventually shrivel or are resorbed.
Pollen mother cells undergo meioses through simultaneous cytokinesis and give rise to tetrads of microspores, which are mostly terahedrally arranged.
Pollen mother cells undergo meioses through simultaneous cytokinesis and give rise to tetrads of microspores, which are tetrahedrally arranged.
The results showed that the microspore abortion occurred at the stage of microspore mother cell, tetrads and uninucleate microspore.
Cytokinesis in the microspore is of the simultaneous type and microspore tetrads are mainly tetrahedral. Pollen grains are mainly 2-celled when shed.
The microspore mother cells give rise to isobilateral tetrads by meiosis. Cytokinesis is successive. The mature pollen grains are 2-celled and are shed singly.
The archesporial cells differentiated from single archesporium , the meiosis of microspore mother cells were continuous type and tetrads were tetrahedral.
Cytokinesis is of the simultaneous type and microspore tetrads are mainly tetrahedral.
