  We consider the string breaking phenomenon within effective string models
which purport to mimic QCD with two light flavors, with a special attention to
baryon modes. We make some estimates of the string breaking distances at zero
and non-zero baryon chemical potentials. Our estimates point towards the
enhancement of baryon production in strong decays of heavy mesons in dense
baryonic matter. We also suggest that the enhanced production of $\Lambda_c^+$
baryons in PbPb collisions is mainly due to larger values of chemical
potential.
