Abstract

In this study, in order to achieve sufficient accuracy both quality and quantity factors in two forestry plantanation of Picea abies using 100% statistics were used. In order to investigate wood quality, fiber length, density and mechanical properties, 4 thick cross section trees were selected and cut in two area of Piseson at high 1450m. altitude and Syahkal at 650m. altitude. According to the results of measuring of diameter, height and average annual growth of the samples and comparison of different sites condition, it could be concluded that plantation of Picea abies is advantageous. Finally, the results show that in Piseson wood with low mechanical properties were produced. The average annual growth of wood in Piseson is 63mm. where as in syahkal is 60mm.
