The True Identity of the “Second Pollen Morphology” of Camellia oleifera—Stomium Cells

Previous studies on Camellia oleifera pollen morphology have indicated dual morphologies, defined as “dimorphism”. However, they were limited to morphological at the end of final development and did not elucidate origin, structure, function second (striate pollen). In this study, differences between two “pollen” types compared by paraffin sections, scanning electron microscopy (SEM), fluorescence microscopy, in vitro germination. The results clearly showed that type was formed stomium cells anther, which is responsible for anther dehiscence. nucleus vesicles cell specifically distributed during development, may be related formation septum, dispersal activity, increase count; microscopic level, mainly consisted wall, large vesicles, nucleus. facilitate rapid dehydration under suitable conditions Furthermore, other species genus suggested pseudopollen, capable partaking deceptive pollination. present study refuted theory pseudopollen are cells, whose structure relates their function. These provide basis further research C. physiology toward improvement pollination rates with agricultural practices or breeding interventions.
