Outline of Final Research Achievements	To insure a stable demand of Japanese lacquer, development of high quality lacquer based on the mechanism of resin production in the lacquer tree, Toxicodendron vernicifluum is urgently needed. Significant basal inner bark structure among the clones with different raw lacquer yields was not noted. However, our study revealed that the clone of the tree with high raw lacquer yields exhibited thicker inner bark, large number and cross-sectional areas of resin canals significantly. We could succeed in inducing to produce the traumatic resin canals along the cambium by the treatment of the plant hormone such as ethylene, and described for the first time the fungus Diaporthe toxicodendri sp. nov., which causes canker disease on the stems and twigs of T. vernicifluum.
