在陆地棉小孢子发生过程中,相邻的减数分裂细胞壁中的细胞质通道是一个明显的特征。
The cytoplasmic channel in the wall of adjacent meiocytes was an obvious feature during microsporogenesis in Gossypium hirsutum.
减数分裂后,小孢子开始退化,首先是小孢子壁开始变形,随后原生质浓缩,形成干秕、皱缩的小孢子。
After the meiosis, however, the microspores began to degenerate to become blighted and wrinkled ones, starting from the deforming of their walls and concentration of their protoplasm.
同一花药不同花粉囊相同一药室,花粉母细胞减数分裂和小孢子的发育,并不是高度同步的。
It is not synchronous highly that the meiosis of pollen mother cells and the development of microspore in the same anther but different pollen sac and in the same anther chamber.
单瓣紫花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。
The results showed that the 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.
