We discuss observables in multiparticle production for three kinds of limits of decreasing kinematical scales: 1. the transition jet → hadron (limit ycut→ 0 of the resolution parameter ycut); 2. single particle inclusive distributions normalized at threshold √ s→ 0 and 3. particle densities in the limit of low momentum p,pT→ 0. The observables show a smooth behaviour in these limits and follow the perturbative QCD predictions, originally designed for large scales, whereby a simple prescription is supplemented to take into account mass effects. A corresponding physical picture is described.
