We carry out a theoretical and Monte Carlo study on the J/{psi} decays into {omega}{pi}{pi} and KK{pi} through intermediate subthreshold {rho} meson by using SU(3)-symmetric Lagrangian approach. It is found that the subthreshold {rho} contribution is not negligible and may have significant influence on partial wave analysis of resonances in these channels, especially near the {omega}{pi} and KK thresholds.
