Abstract: In this study, the chemical composition, fiber morphology, pulp, and paper properties of the pomegranate tree (Punica granatum L.) were determined. Stem and branch wood were analyzed separately. Kraft and kraft- anthraquinone (AQ) methods were used for the pulping processes. Stem wood showed superiority to branch wood with longer, wider, thicker-walled fibers. The holocellulose, $\alpha$-cellulose, and lignin contents of branch and stem wood were 72.98%-73.50%, 38.37%-39.92%, and 21.04%-25.29%, respectively. In addition, the yield of kraft pulp made from stem wood was higher than that of branch wood. However, branch wood handsheets had higher strength properties and brightness than those of stem wood handsheets.
