Research on variation of microfibril angle in Phyllostachys pubescens
Variations of microfibril angle of Phyllostachys pubescens with different heights, ages, radial positions were studied by X-ray diffraction technique. The results showed that microfibril angle increased first, and decreased from outside to inside in radial direction of the walls, finally it reached to the minimum ai the inside of the walls. The difference between the maximum and minimum values of microfibril angle was less than 4.17 .Moreover, the microfibril angel increased slightly from base to top of the stalks. The difference was less than 0.15 . In addition, the microfibril angle increased first, then decreased from 0.5-year to 6-year, whose difference was less than 0.52. At last, significant different effects of the microfibril angle with different ages, heights and radial positions of Phyllostachys pubescens were showed by analysis of variation.
