Culm Age and Rhizome Affects Night-Time Water Recharge in the Bamboo Phyllostachys pubescens
Bamboo species-the only herbaceous trees-have unique structural and physiological characteristics that differ from those of other tree taxa. However, the role of night-time water use in bamboo is poorly understood and has rarely been investigated. We studied the day- and night-time sap flow response to culm age and rhizome structure in three age levels (juvenile, mature, and senescent) of Phyll...
متن کاملVariation of Parallel-to-Grain Compression and Shearing Properties in Moso Bamboo Culm (Phyllostachys pubescens)
As an abundant natural resource in Asia, bamboo is receiving increased attention as an engineering material due to its renewability and excellent strength. The parallel-to-grain compression and shearing properties of moso bamboo culm were examined. The growth characteristics (bamboo age, nodes, and location along the culm), as well as treatments for practical applications (hole punching and hoo...
متن کاملSELECTED PHYSICAL AND MECHANICAL PROPERTIES OF MOSO BAMBOO (Phyllostachys Pubescens)
YU, H. Q., JIANG, Z. H., HSE, C. Y. & SHUPE, T. F. 2008. Selected physical and mechanical properties of moso bamboo (Phyllostachys pubescens). Selected physical and mechanical properties of 4–6 year old moso bamboo (Phyllostachys pubescens) grown in Zhejiang, China were investigated at different vertical and horizontal positions. Two way analysis of variance and Tukey’s mean comparison tests in...
متن کاملComparative Research between Rhizome and Culm of Phyllostachys pubescens Based on Thermal Analysis
A systematic study was conducted on P. pubescens by analyzing thermal characteristics of its rhizome and culm (1.5 m) at different ages, using various analyses such as X-ray diffraction (XRD), differential scanning calorimetry (DSC), and thermogravimetry (TG). For both the rhizome and culm of P. pubescens, the relative crystallinity (Cr) of cellulose increased and then appreciably decreased wit...
متن کاملComparison of Variations in the Chemical Constituents of the Rhizome and Culm of Phyllostachys pubescens at Different Ages
A systematic study was conducted on Phyllostachys pubescens by analyzing the chemical constituents of its rhizome and culm at different ages. Our results indicated that the ash contents of the rhizome and culm of P. pubescens at different ages showed the largest coefficient of variation (CV), followed by alcohol benzene extractives. The CVs of acidinsoluble lignin, holocellulose, HNO3-C2H5OH ce...
