Abstract

Amyloplast structure and intercellular transport in old and new scales ofFritillaria ussuriensis were observed by means of electron microscope. Most amyloplasts in old scales contained one starch grain, which was constructed by the layered deposition of starch around the hilum. Membrane systems and stroma of amyloplasts were pushed aside to form a shell surrounding the starch grain. In contrast, amyloplast shells in new scales contained a relatively light stroma and few internal membranes that were not organized into grana and stroma thylakoids. Active intercellular transport was observed in both new and old scales. Encytosis and exocytosis were common in the cell membrane and produced many vesicles containing numerous particles and filaments. These results lay the foundation for the further study on the mechanisms of growth and development in
