Abstract

Selected anatomical and physical properties of stems of Calamus deeratus, Eremospatha dransfieldii, Eremospatha macrocarpa, Laccosperma acutiflorum and Laccosperma secundiflorum in the natural forest of Ghana were investigated to aid in understanding their quality and to promote their efficient utilization. Fibre lumen diameter, double fibre wall thickness (fibre diameter minus fibre lumen diameter) and proportion of fibres exhibited a more definite pattern of variations within and between all the five species than other anatomical properties. Generally, proportion of fibre and double fibre wall thickness decreased, whereas fibre lumen diameter increased from base to top internodes. Initial moisture content increased consistently from base to top internodes whilst relative density decreased in the same direction. Simple regression analysis of physical properties on anatomical properties revealed that fibre lumen diameter, double fibre wall thickness and proportion of fibre are important parameters likely to influence initial moisture content and relative density along the stems and between all species investigated. Stem quality of all five species is also discussed.

加纳五种藤棕榈茎部解剖和物理特性的变异

摘要对加纳天然林中的枯菖蒲(deeratus)、长叶菖蒲(Eremospatha dransfieldii)、大叶菖蒲(Eremospatha macrocarpa)、长叶菖蒲(Laccosperma acutiflorum)和次生叶菖蒲(Laccosperma secondiflorum)的茎进行了解剖和物理性质的研究，以了解其质量，促进其有效利用。纤维管腔直径、双纤维壁厚(纤维直径减去纤维管腔直径)和纤维比例在所有五个物种内部和之间表现出比其他解剖特性更明确的变化模式。从基部到顶部节间，纤维比例和双纤维壁厚逐渐减小，纤维管径逐渐增大。从基部到顶部节间初始含水率持续增加，而相对密度在同一方向呈下降趋势。物理性质对解剖性质的简单回归分析表明，纤维腔直径、双纤维壁厚和纤维比例是影响茎和各物种间初始水分含量和相对密度的重要参数。还讨论了这五种植物的茎质量。

期刊介绍： The Journal of Bamboo and Rattan is a peer-reviewed scientific journal and provides a forum for scientific articles and reviews on all aspects of fast growing, multi-purpose pliable species. The scope of the journal encompasses income security, craft industry, small to medium size enterprises, industrial fibre and fuel. Articles related to natural distribution and conservation of species, genetics and biotechnology, harvesting and production systems, and environmental applications are also included, as well as papers on marketing and policy restraints in relation to bamboo, rattan and related species.
