Endeavor to increase the growth rate of red meranti (Shorea leprosula Miq.) in natural forest has been carried out through the silviculture system of selective cutting and line planting (TPTJ). Even though high growth rate has been understood tend to decrease certain basic properties of wood; however measurement of the basic properties specifically done on the red meranti resulted from thinning and line planting treatment has been lacking. In the present research, measurement of the basic properties of red meranti resulted from thinning and line planting treatment was done. It was found that thinning and increasing line planting increased the diameter of tree, longitudinal shrinkage, fiber diameter, lumen diameter, sapwood extractives, and ash content. On the other hand, these treatment decreased heartwood proportion, crown coverage, specific gravity, wood density, radial and tangential shrinkage, fiber length, cell wall thickness and heartwood extractives. Lignin, holocellulose, -cellulose and hemicelluloses were not significantly influenced by the treatments.
