We report the synchronization of two nonidentical spatially extended fields, ruled by one-dimensional complex Ginzburg-Landau equations, both in the phase and in the amplitude turbulence regimes. In the case of small parameter mismatches, the coupling induces a transition to a completely synchronized state. For large parameter mismatches, the transition is mediated by phase synchronization. In the former case, the synchronized state is not qualitatively different from the unsynchronized one, while in the latter case the synchronized state may substantially differ from the unsynchronized one, and it is mainly dictated by the synchronization process of the space-time defects.
