Abstract

Delignified and/or xylanase-treated secondary walls of Fagus crenata fibers were examined by field emission scanning electron microscopy. Microfibrils with a smooth surface were visible in the innermost surface of the differentiating fiber secondary wall. There was no ultrastructural difference between control and delignified sections, indicating that lignin deposition had not started in the innermost surface of the cell wall. There was no ultrastructural difference between control and xylanase-treated sections. Microfibrils on the outer part of the differentiating secondary wall surface had globular substances in delignified sections. These globular substances disappeared following xylanase treatment, indicating that these globules are xylan. The globular substances were not visible near the inner part of the differentiating secondary wall but gradually increased toward the outer part of the secondary wall, indicating that xylan penetrated into the cell wall and continuously accumulated on the microfibrils. Mature-fiber secondary walls were also examined by field emission scanning electron microscopy. Microfibrils were not apparent in the secondary wall in control specimens. Microfibrils with many globular substances were obse...Continue Reading
