Abstract
The relationship between the character (morphology, chemical composition) of plantation wood chips (E. globlus, E. nitens, E. grandis, E. camaldlensis, E. exerta, A. mangium, A. auriculiformis, A. hybrid (A. mangium×A. auriculiformis)) and pulp properties was investigated. The results showed that fiber morphology in wood chips has a great influence on sheet properties, and that the lower lignin content in wood chips gives less energy for pulping and higher pulp yield. However, there were some exceptions to relationship between pulping efficiency and lignin content. In order to evaluate pulp properties of new wood chips, it is necessary to make pulping tests and measure the fiber morphology.
