We analyse in this paper to what extent the rise of the real part of Regge trajectories is due to contributions from baryon‐antibaryon thresholds and to what extent it is connected with the presence of a linear term. It is shown that sewing the trajectory from the scattering to the resonance region results in “switching off” the linear term; the remaining contributions of various thresholds guarantee the necessary linearity of the trajectories.
