The unitary corrections to the linear Regge trajectories due to planar loop diagrams are calculated in the generalized Veneziano model and in the Neveu–Schwarz–Ramond model. The divergent parts of these corrections to the $\rho$-trajectories lead to a renormalization of the trajectory slope. There is no renormalization of the $\rho$-intercept.
