In order to obtain mechanical properties and provide necessary theoretical basis in the harvest, transportation, storage and industrial production of the white radish, mechanical properties (stress, elastic modulus) of white radish were measured and analyzed. Loading position, the loading direction, loading speed and moisture content were considered as affecting factors on the mechanical properties of white radish. Results showed that the compression capability of central position of white radish was stronger, and the lower position's was weaker (elastic modulus were 2.16, 2.07 MPa respectively). White radish was anisotropic. The axial compressive strength was stronger than in radial direction (the elastic modulus of axial and radial directions were 2.19 MPa, 1.98 MPa respectively). The elastic modulus were increased with reduction of moisture content. So the radial force should be avoided during the transport process of white radish.
