Abstract: Investigations were made on the physical, chemical and fibre morphological parameters and fibre derived indices of three pulpwood species viz. Eucalyptus, Melia and Casuarina for pulp and paper making. Eucalyptus, Melia and Casuarina trees were selected, felled and wood samples were collected from respective plantations established in Forest College and Research Institute, Mettupalayam. Basic density of wood samples were measured using Shimadzu electronic balance attached with specific gravity module. Fibre maceration was done by Jeffrey’s method and holocellulose and lignin content by Tappi method. Basic density and fibre morphological parameters showed significant variation (at 1%) between species. The highest basic density was observed for Casuarina followed by Eucalyptus and the minimum for Melia. The high fibre length and fibre wall thickness was observed for Casuarina followed by Eucalyptus and Melia. The fibre diameter and fibre lumen width was highest for Melia followed by Casuarina and Eucalyptus. Chemical composition was almost same for all the species; holocellulose ≈73% and lignin ≈23%. Studies on suitability of species for paper making showed that Eucalyptus is preferred in terms of its moderate basic density and optimum fibre morphological parameters. Low fibre length of Melia and high fibre wall thickness of Casuarina adversely affected its paper making properties. However in terms of fibre derived indices, Melia dubia was found to be most suitable for paper making followed by Eucalyptus and Casuarina.
