Chemical composition of leaves and wood fiber dimension in ramie stalk

The main purpose of this paper was to evaluate the potential uses of the ramie plants (Boehmeria nivea Gaud.) after the bast fiber extraction (textile fiber). The chemical composition of leaves and woody fiber dimensions of ramie stalk were determined. The results showed that the ramie leaf dry matter presented the following average composition: crude protein 19.59%, crude fiber 12.98%, carbohydrates 43.10%, ash 19.10%, calcium 6.24%, ether extract 5.23% phospurus 0.17%, magnesium 0.59%, and iron 0.038%. These data compared to the alfafa composition, indicate that ramie leaves can be used for animal feed. The average values for fiber length, fiber width, lumen and cellwall thickness were, respectively 0.57mm, 23.7µm, 11.85µm and 5.92 µm. The fiber length value can be considered extremely short, in comparison with Eucaliptus and Pinus fiber.
