Using the combined version of light-quark (qq-bar ..-->.. bb-bar) and gluon-gluon (gg ..-->.. bb-bar) fusion mechanisms for hadronic UPSILON (9.5) production, we give predictions for x/sub F/ distributions using pion and proton beams, and for various total-cross-section beam ratios. In addition, we make a detailed comparison of counting-rule--like nucleonic and pionic parton distributions with those predicted by dynamical quantum-chromodynamics (QCD) calculations, and give analytic parametrizations of their QCD x and Q/sup 2/ dependence.
