  Hadronic events at the Z pole have been investigated in search for Colour
Reconnection effects and QCD coherence. Colour Reconnection effects are
searched for in three-jet events and the data results are compared to the
predictions of different Monte Carlo models. QCD colour coherence effects are
tested through the multiplicity distributions of hadrons with restricted
momenta, and the LEP1 e+e- data is compared to HERA e+p data under the
equivalence assumption of the e+e- hemisphere with the current region of the
Breit frame of reference.
