We suggest that there might be a production of a large number of glueballs in relativistic nucleus-nucleus collisions if the quark-gluon plasma (QGP) phase is realized. The ratio of the number of the produced glueball to that of the neutral pions directly produced in the process of QGP hadronization is estimated phenomenologically. Being a function of the phase transition temperature and chemical potential, it can be as large as a few percents. Considering the fact that the hadronization is very complicated, we anticipate that the abundant population of glueballs from the quark-gluon plasma at least may exert influences on the final-state K+/pi(+) ratio.
