We characterize the synchronization of two nonidentical spatially extended elds ruled by onedimensional Complex Ginzburg{Landau equations, in the two regimes of phase and amplitude turbulence. If two elds display the same dynamical regime, the coupling induces a transition to a completely synchronized state. When, instead, the two elds are in di erent dynamical regimes, the transition to complete synchronization is mediated by defect synchronization. In the former case, the synchronized manifold is dynamically equivalent to that of the unsynchronized systems, while in the latter case the synchronized state substantially di ers from the unsynchronized one, and it is mainly dictated by the synchronization process of the space-time defects.
