Abstract
Chemical and kraft pulp properties of culm were investigated in three bamboo species (Bambusa vulgaris, Bambusa maculata and Gigantochloa atter) naturally grown in four different provenances of Lombok Island, Indonesia. The among-provenance variations of these characteristics were also evaluated. The amounts of chemical components (extractives, ash, Klason lignin, holocellulose, and α-, β- and γ-cellulose) in these three species were in the range of those values in the same genus. Kraft pulp yield and kappa number ranged from 49.0 to 52.3% and from 18.7 to 22.3, respectively. Variance components of the provenance in mixed-effect models were large in several chemical components, suggesting that these properties vary among provenances due to differences in their genetic backgrounds. Thus, provenance selections should be conducted to effectively utilize bamboo culms for chemical products.
