With these newly derived relations, we investigate five series of hexaquark Regge trajectories: the $\\lambda$-, $\\rho_1$-, $\\rho_2$-, $\\sigma_1$-, and $\\sigma_2$-trajectories. We demonstrate that, apart from the simplest $\\lambda_1$-trajectories, the $\\rho_1$-, $\\rho_2$-, $\\sigma_1$-, and $\\sigma_2$-trajectories cannot be constructed by merely mimicking the meson Regge trajectories, since mesons possess no internal substructures.
