We apply a variant of the recombination model which we call the ''valon-parton model'' simultaneously to a variety of meson inclusive reactions with proton, pion, and kaon beams in the kinematic region of low transverse momentum and intermediate values of longitudinal-momentum fractions. We find that the valon distributions in hadrons show no evidence for SU(3) breaking. There are some indications of substantial gluon-dissociation contributions which we interpret through a ''maximally enhanced sea.'' For proton-induced reactions the model predictions are in excellent agreement with data; meson-induced reactions indicate additional contributions are coming from resonances which are produced recombinantly and then decay into the observed mesons.
