Protoplanetary discs are disc-shaped structures around T-Tauri stars which are composed of gas and dust. The matter in the disc is accreted onto the host star in a time of several million years. During this phase, the dust particles grow to form larger bodies, eventually leaving behind a planetary system after the disc is gone. It is assumed that the accretion process is powered by turbulence, which most likely is of magnetic origin. The turbulence is not only important concerning the evolution of the disc in general, but might possibly also play a key role in the process of planet formation. In the present thesis, we describe numerical models of magnetorotational turbulence in protoplanetary discs. We use a modern finite-volume grid code w...
