Deterioration and preservation of Japanese pampas grass as a roofing material
1991 - IRG/WP 1490

The vessels were the most important pathway of microbial prevalence. Hyphae invaded into the cell wall of fiber and parenchyma, and made the cavities with conical ends. The contacting cell wall of parenchyma in pith with hyphae was decompose...
