| Abstract: | The study on the structures of the root and adventitious bud of one-year-old Aralia elate seedlings revealed that the root went on secondary growth, and more differentiation existed in secondary phloem with two circles of regular resin duets. Early wood and late wood were obvious in secondly xylem, and canal molecular perforation plate included simple perforation plate, scalar-formed perforation plate and reticulate perforation plate. The vascular ray was developed and the development of periderm was obvious. A large number of adventitious buds could be seen on the roots, and the adventitious buds originated from the secondary phloem cells. |
