The resistivities p^ and pL of the single crystals of YBa2Cu3Ox have been measured in the directions parallel to the basal plane of the unit cell and perpendicular to it. The samples of the two sets of crystals with orthorhombic structure (Tc ~ 93 K) and tetragonal structure (Tc ~ 80 К) have been studied. The transverse resistivity pL and anisotropy pL /рц were found to increase as the temperature approached Tc.
