Abstract: Amorphophallus konjac of Qingjiang was taken as material, and the formation process of the rhizome was revealed through anatomical study. The results showed that the rhizome was formed by the germination of adventitious buds on the konjac bulb, which was like a rod, with terminal buds at the apex. The structure of cortex and terminal buds was similar to that of the konjac bulb. The growth of the rhizome ended with plant senescence. The rhizome of konjac was actually a reduced version of the bulb, but the cortex was thicker than the bulb and the terminal bud was tighter than the bulb. Therefore, the rhizome was not easy to be damaged during transportation. It was suggested that the rhizome should be used for the provenance of the newly developed konjac planting place.

Key words: Amorphophallus Konjac, rhizome, anatomical structure
