  The phenomenological evidence of quantum statistical effects in parton
physics is here briefly summarized, and the recent good results obtained by
parameterizing the parton distributions in terms of Fermi-Dirac and
Bose-Einstein statistical functions are discussed. In this framework we study
the modification of the scaling behaviour of parton distributions due to
quantum statistical effects. In particular, by following a well-known formal
analogy which holds between the Altarelli-Parisi evolution equations, at
leading-log approximation, and a set of Boltzmann equations, we suggest a
generalization of evolution equations to take into account Pauli exclusion
principle and gluon induced emission.
