  Results from a phenomenological analysis of dijet and W hard diffractive
hadroproduction at Fermilab Tevatron energies are reported. The theoretical
framework employed here is a modified version of the Ingelman-Schlein approach
which includes DGLAP-evolved structure functions. Different from what has been
achieved by the DESY ep HERA reactions, a reasonable overall description of
such diffractive hadron processes is obtained only when a complex, quark-rich
Pomeron structure function is employed in the calculation.
