Using results from phenomenological analysis of high energy \\pi-N charge-exchanged scattering process, we get the expression of effective propagator of R_\\rho and the coupling constant \\beta_\\rho between R_\\rho and light quarks. As a simple and concrete example, we use them to evaluate the contributions of R_\\rho to F_2(x,Q^2) from charge-exchanged photoproduction quark-pair process,\\gamma^* + p-->n + q_u + \\bar{q}_d (--> n + X), in HERA kinematical regions.
