Abstract
Magnetoresistivity measurements were made in untwinned YBa2Cu3O7-delta abov e T-c for B\\c and B\\ab, with I\\a or b. A fluctuation theory that allows for an in-plane coherence length anisotropy (gamma = xi (b)/xi (a)) was use d to determine gamma. The contribution to the magnetoconductivity from the CuO-chains was also analyzed.
