| Outline of Final Research Achievements |
Near infrared (NIR) spectra collected from Japanese cedar wood samples, which were decayed by white rot (Trametes versicolor) and brown rot (Tyromyces palustris), were subjected to principal component analysis. Most of the PC1 score of brown rot was negative and that of white rot was positive. The separating was contributed by spectra that were in the lignin-assigned wavenumber region. This result showed the NIR spectrum could distinguish between the white rot and the brown rot. Using this method, scores of dead wood samples of Japanese cedar, which collected from planted forests around country, distributed along PC1 axis. While higher score of PC1 would relate to white rot, lower score would relate to brown rot. Those results show that NIR spectra are effective for the fungal decay classification.
