| Outline of Final Research Achievements |
We investigated the causal fungi and the factors for development of stem saprot of sugi. One of the causal fungi was revealed a possible undescribed Physisporinus sp. A stem rot disease caused by Fomitiporia torreyae was recorded from Kyoto for the first time that were known only from a restricted part of Kanto Region. We inoculated Xeromphalina curtipes, F. torreyae and Physisporinus sp. onto living stems showing that these fungi frequently colonize into living sapwood of sugi. Stem injure during the summer time is considered a serious risk for sugi stem saprots, because inoculations in summer induce frequent colonization of the inoculated fungi.
