Abstract:
To investigate the microfibril angle (MFA) variation with respect to positions along longitudinal direction (bottom, middle and top of culm) and radial direction (from inner part to outer part of culm wall) of Guadua amplexifolia, MFA was measured by SilviScan-3 and X’Pert Pro(XRD). There was no significant difference between MFA measured by SilviScan-3 and XRD. Simple coefficient of correlation was 0.84.The mean MFA measured by SilviScan-3 and XRD were 8.2° and 8.8° respectively, and varied from 6.2° to 17.8° and from 6.9° to 12.2°. Compared with XRD, SilviScan-3 provided a continuous and more rapid method for determining MFA variation in bamboo culm. According to results of SilviScan-3, MFA in bottom was higher than that of in middle which was higher than that of in top of culm. Maximum MFA occur in inner layer, MFA decreased rapidly from inner layer to 2 mm, and fluctuated stably from 2 to 6.5 mm, and then increased subtly from 6.5 mm to outer layer. The radial tendency of MFA in the bottom was similar to that in middle and top of culm.
Key words: Guadua amplexifolia, microfibril angle, SilviScan-3, variation
