  The interrelation between the deconfinement temperature of hadron medium and
parameters of radial Regge trajectories within the bottom-up holographic models
for QCD is scrutinized. We show that the lattice data on the deconfinement
temperature can yield a powerful restriction on the spectrum of excited mesons
and glueballs within the framework of holographic approach. The best
phenomenological agreement and theoretical self-consistency are achieved if the
scalar meson $f_0(1500)$ is considered as the lightest glueball.
