N2 - We calculate in two-dimensional QCD (QCD[Formula presented] the ratios of baryonic matrix elements of [Formula presented] and [Formula presented] four-fermion operators, with a view to understanding better the mechanism of [Formula presented] enhancement in QCD[Formula presented]. We find relatively small suppressions of both the scalar-scalar and vector-vector [Formula presented] four-fermion operators. We discuss the possible implications of these results, in view of a suggestion that gluon condensation may be an important contributing factor in the [Formula presented] enhancement seen in QCD[Formula presented]. At the technical level, our calculation of the vector-vector operator matrix element requires a treatment of the time dependence of the QCD[Formula presented] soliton which had not been developed in previous phenomenological calculations within this model.
