abstract:
The paper describe the measuring set for determination of restitution coefficient of rape seeds and preliminary results. The restitution coefficient is one of the physical properties of seeds that characterize their behavior during impact. Six varieties of rapeseeds were measured and compared using this method. Big differences between varieties were found for time of deformation and value of max.
