Lacquer tree specimen

                          Lacquer tree specimen apex
This data is the result of an identification study of lacquer trees from the Jomon period by Professor Mitsuo Suzuki of the Botanical Garden, Tohoku University. It is characterised by the fact that the diameters of the vessels increase with the growth of the tree in the earlywood portion of the annual rings.
The specimen is a branch with seeds and winter buds sent by Mr Shunzo Omori. It can be seen that the data are consistent with the data.
In the central part, where there is no data, the diameters of the ducts are uniform between the earlywood and latewood parts. The hardness is also low and qualitatively completely different from the second year onwards. This is a common characteristic of both unevenness and evenness trees.
