  The partial widths are determined for squark decays to gluinos and quarks,
and gluino decays to squarks and quarks, respectively. The widths are
calculated including one-loop SUSY-QCD corrections. The corrections amount to
$+$30\% to $+$50\% for squark decays and $-$10\% to $+$10\% for gluino decays.
We have derived the results in the \DR ~and \MS ~renormalization schemes, and
we have demonstrated explicitly that the one-loop effective $qqg$ and $q\sq\gl$
couplings are equal in the limit of exact supersymmetry.
