Abstract
The growth rate for instabilities in an expanding parton plasma is
investigated by using a quasiparticle transport model including hadronization. The
coupled Boltzmann equations for partons and pions with time dependent
mean field masses and source terms are solved in the Bjorken boost
invariant picture. Hadronization modifies the known
instability in the parton plasma created by the mean field in two ways:
In the beginning, hadronization increases the rate 
of
instability, but then 
when
the hadronization is dominating the time evolution.
