1) The digestion and deposition of the starch grains in the growing pollen of Tradescantia were observedaand figured. (figs. 1)
2) In the immature pollen of Tradescantia, Lilium, Antirrhinum, Gladiolus and some other species the storage starch were found abundantly, but with the progress of maturation the starch grains became empty. (figs. 1, 3, 4)
3) The mature pollen of Tradescantia occured plasmolysis more easily than immature pollen (table 1). The result indicate that the storage starch are transformed into sugar.
4) The sugars in the pollen of Impatiens, Zea, Narcisus, Camellia, Lilium, Cucurbita, and Antirrhinum were investigated by mean of paper chromatography. Sucrose, glucose and fructose were found in the respective pollen grains (fig. 5).
5) On the artificial culture media sucrose in the Lilium and Camellia pollen gradually removed, than glucose and frucotose increased (figs. 6).
