Pollen morphology of the Chinese monotypic genus Dichotomanthes and its out-group Prinsepia utilis were investigated from the point of view of pollen development. The SEM observation revealed that there is not any change in morphology and sculpture of pollen grains from the young pollen grain seperated from callose of tetraspore to the mature pollen grain in Dichotomanthes tristaniaecarpa. Only the volume of pollen grain increased with maturity.

目的 探讨卵细胞第一极体形态与原核期受精卵形态、卵裂期胚胎质量的关系。

Based on the observation of atomic force microscopy, the etching morphology of faces and sections with different crystallographic significance on α-quartz has been studied. The etching morphology on the natural crystal faces hexagonal prism faces (1010 and 01(average10, rhombohedron positive form face 10(average11, rhombohedron negative form face 01(average11 and the sections between any of the two crystal faces has been observed. It is shown that the etching pit on the same simple form has the same shape, while the orientation of the etching pits can be different. Different simple forms have different shapes of etching pits and the shapes of etching pits on positive form and negative form of the same simple form are also different.
