  We discuss the behaviour of the energy spectrum of particles in jets near the
limit of small momenta of a few hundred MeV. In QCD parton cascades the soft
gluons are coherently emitted from all faster partons in the jet and their
production rate is predicted to scale. The observed charged and identified
particle spectra follow this behaviour surprisingly well supporting of the
hypothesis of the Local Parton Hadron Duality (LPHD) for this extreme limit.
Further tests of this perturbative approach are discussed.
