Associative spectra of graph algebras are examined with the help ofhomomorphisms of DFS trees. Undirected graphs are classified according to theassociative spectra of their graph algebras; there are only three distinctpossibilities: constant 1, powers of 2, and Catalan numbers. Associative andantiassociative digraphs are described, and associative spectra are determinedfor certain families of digraphs, such as paths, cycles, and graphs on twovertices.
