Abstract (2. Language): 
In this research, some of physical properties at various moisture content were de-termined for Pinus pinea L. fruits (stone pine) collected from the region of Mut (İçel), Turkey. The physical properties of stone pine kernel and pits were deter-mined as a function of moisture content in the range of 7.25-20.52% and 8.82-28.84 % dry basis (d.b.) for pit and kernel respectively. The correlation coefficient between length and mass of stone pine pit and kernel were found significant at 7.25% and 8.82% moisture content (d.b.) for pit and kernel respectively. As the moisture content increased, the sphericity, thousand grain mass, bulk density, true density, terminal velocity, and projected area increased for stone pine pit and ker-nel. The coefficient of static friction of stone pine pit and kernel increased against the surface of two structural materials, namely, a galvanised steel sheet (0.343-0.489) and plywood sheet (0.5-0.521) for stone pine pit, and a galvanized steel sheet (0.383-0.435) and plywood sheet (0.442-0.471) for stone pine kernel as the moisture content from 7.25 to 20.52% and 8.82 to 28.84% (d.b.), respectively. Both the rupture strength value of stone pine pit and the hardness of stone pine kernel decreased as the moisture content increased.
