Conteúdo: | The purpose of this investigation was the study of Eucalyptus spp wood characteristics and their unbleached sulphate pulps. The following species were analysed: E.saligna (8 and 13 year-old), E.paniculata (6 and 10 year-old), E.citriodora (7 and 13 year-old), E.maculata (7 year-old) and E.tereticornis (7 year-old). Regarding wood characteristics, E. citriodora, E. paniculata, E. maculata shown higher specific gravity and thicker-walled and stiff fibers. Pulp yields were higher for E. paniculata (10 year-old) and E. saligna (8 year-old). Higher tear strength were reached on E. citriodora wood pulps. Burst and tensile strengths were better on E. saligna (8 year-old), E. tereticornis (7 year-old) an E. maculata (7 year-old). Denser sheets were obtained from E. saligna, E. tereticornis and E. maculata. Pulp blending studies were suggested by the authors.
