Abstract :In this research some physical properties at different moisture content were determined in developing Pinus pinea L. fruits insert ignore into journalissuearticles values(stone pine); from Mut insert ignore into journalissuearticles values(İçel);, Turkey. Physical properties of stone pine kernel and pits were determined as a function of moisture content in the range of 7.25-20.52% dry basis insert ignore into journalissuearticles values(d.b.); for pit and 8.82-28.84 % insert ignore into journalissuearticles values(d.b.); for kernel. The correlation coefficient between length and mass of stone pine pit and kernel were found significant at 7.25% moisture content insert ignore into journalissuearticles values(d.b.); for pit and 8.82% moisture content insert ignore into journalissuearticles values(d.b.); for kernel. 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 kernel. The coefficient of static friction of stone pine pit and kernel increased against the surface of two structural materials, namely, a galvanised steel sheet insert ignore into journalissuearticles values(0.343-0.489); and plywood sheet insert ignore into journalissuearticles values(0.5-0.521); for stone pine pit, and a galvanized steel sheet insert ignore into journalissuearticles values(0.383-0.435); and plywood sheet insert ignore into journalissuearticles values(0.442-0.471); for stone pine kernel as the moisture content from 7.25 to 20.52% and 8.82 to 28.84% insert ignore into journalissuearticles values(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.
