  We calculate in QCD$_2$ the ratios of baryonic matrix elements of $\Delta I =
2$ and $\Delta I = 0$ four-fermion operators, with a view to understanding
better the mechanism of $\Delta I = 1/2$ enhancement in QCD$_4$. We find
relatively small suppressions of both the scalar-scalar and vector-vector
$\Delta I = 2$ 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 $\Delta I = 1/2$ enhancement seen in
QCD$_4$. At the technical level, our calculation of the vector-vector operator
matrix element requires a treatment of the time dependence of the QCD$_2$
soliton which had not been developed in previous phenomenological calculations
within this model.
