Properties of Eucalyptus Camaldulensis wood grown in southern region of Iran
Eight-nineteen-year-old trees from Eucalyptus camaldulensis from De- hnow experimental Plantation located 160 Km. South west of Shiraz were selected randomly and fell two from each of the four blocks. Form each tree, 10 cm. thick cross-sectional discs at several different heights (3 meters intervals...

| Sumario: | Eight-nineteen-year-old trees from Eucalyptus camaldulensis from De- hnow experimental Plantation located 160 Km. South west of Shiraz were selected randomly and fell two from each of the four blocks. Form each tree, 10 cm. thick cross-sectional discs at several different heights (3 meters intervals) were cut and together with remaining boles then transferred to the Alborz Research Center-Karaj for laboratory studies. The laboratory studies included determination of physical, anatomical and mechanical properties as well as chemical compositions of wood.The mechanical properties were evaluated on the ASTM methods for air-dry and green conditions. The following conclusions were drawn from this study:E. camaldulensis from one site in southern region of Iran has an average specific gravity of 0.806, Fiber length of 1.043 mm, fiber diameter of 15.38 mm, lumen diameter of 4.84 mm, cell wall thickness 5.29 mm, cellulose content of 42.5 percent. It was found that the mean values of modulus of rupture, modulus of elasticity and compression strength-parallel to grain tested at green condition were 81.19 MPa, 10887 MPa and 67.39 MPa respectively.Data are also presented on other mechanical properties such as impact strength, nail withdrawal cleavage and etc. |
