We consider the Schwinger-Dyson equation for the fermion propagator in quantum chromodynamics in the infrared region. In two different gauges, the axial and covariant gauges, and on the assumption that the gluon propagator has a power infrared asymptotic behavior we find that a massive solution for the fermion Green function may be obtained with certain mass values. At the same time the infrared asymptotic behavior of the gluon propagator in the gauges considered must have the form 1/(k/sup 2/)/sup 2/. A possible interpretation of the results is discussed in application to the problem of a dynamical origin of the quark masses.
