Abstract

Morphology of generative cells in pollen grains of 10 plants of Sect.Camellia and Sect. Oleifera was observed with LM.Results showed that there were vegetative cell and generative cell in the pollen grain of Genus Camellia, the generative cell is more smaller than that of the vegetative cell.The generative cell was lay on the vegetative cell as an elongate spindle, and only the generative cell membrane and nuclear membrane which near the cell polar linked up the vegetative cell membrane, one of the linked area was located near by the aperture of pollen grain. The nuclei of generative cells showed five types of morphological characters: more elongate club, elongate club, short club, approximate wedge-shaped and wedge-shaped. The length of generative cell nuclei is 3.5~20.0μm.study method on morphology of generative cells in pollen grains,and theevolutionistic tendency of Genus Camellia base on the morphological character and size of generative cell nuclei was also discussed in this paper.
