Abstract
The present study was conducted during 2012 and 2013 in Serabium forest. The aim of this study was to estimate tree biomass and some wood mechanical properties of Cupressus sempervirensL andCorymbiacitriodora Hook. The results showed that C. citriodora was superior over C. sempervirens for most of biomass parameters (total and merchantable height, total volume, green and dry weight and total above-ground biomass) at the age of 5 and 7 years. However, the increment percentage of biomass from 5 to 7 years of age was higher in C. sempervirens than C. citriodora. Mechanical properties obtained from the static bending test, Modulus of Elasticity (MOE), Modulus of rupture (MOR), and Tensile strength recorded higher mean values as the trees get older while they recorded lower mean values from base to top within thetree for both species. Mean values of MOE, MOR and Ten.st. for C. sempervirens at age of 7 years old at DBH were 8128.5, 83.0 and 64.4 N/mm2; respectively, while, these values were 15503.5, 158.8 and 149.0 N/mm2; respectively for C.citriodora. These results revealed that, wood mechanical properties for C.citriodora were higher than C. sempervirens.
