ObjectiveThe purpose of this study was to investigate the variation of physical mechanic properties of Phyllostachys edulis distributed in different subtropical provenance regions.
MethodThree natural populations of Moso bamboo were obtained distributing in Anhui, Guangxi, and Zhejiang provinces, 8 physical mechanic properties were analyzed using one-way ANOVA and principal component analysis based on R language.
ResultThe physical mechanic properties of Moso bamboo were significantly different from 3 populations, the peaks of shrink, moisture content, micro fibril angle and bending strength were all from Guangxi Zhuang Autnomus Region. The variable coefficient of these traits did not show obvious trend and regulation. PCA analysis showed that bending strength, modulus of elasticity, oven-dried volume shrinking ratio, air-dried volume shrinking ratio, and moisture content were the most dominant properties in the 8 physical mechanic properties.
ConclusionOverall consideration, the Moso bamboo from Guangxi Zhuang Autnomus Region was characterized by high strength and high density during these 3 provinces, it is more suitable for processing and utilization as engineering materials. The research results will provide the theoretical basis for excavating excellent species of Moso bamboo in different geographical environments and rationally utilizing the bamboo resources in China’s entire distribution latitude.
