| Outline of Final Research Achievements |
The atomic force microscope (AFM) was applied to observation of cell walls of hinoki (Chamaecyparis obtuse) with the aim of studies on ability of application of AFM to measurement of physical properties of wood materials such as microfibril angles. Oval shaped structures (150-600 nm longer radius, 100-300 nm minor radius) and round shape structures (100-300 nm radius) were observed on the section of tracheid cut with a sliding microtome. If a bundle of microfibrils has round shaped cross-section, the structure appears as oval shape with respect to the microfibril angle. Then, the structure of the oval shape or round shape contains information on microfibril angle.
