Out of the 720 seeds placed into pellets, 34% germinated. U.dioica, O. vulgare, T. repens and F. lemanii represented 41.2%, 25.3%,18.4% and 15.1% of total seed germination respectively. Seedgermination rate was impacted by the seed species factor (GLM,x2 = 351.4, df = 3, p < 0.001, n = 240) and by the interaction betweenearthworm species and soil types (GLM, x2 = 333.2, df = 3, p = 0.006,n = 240). The seed germination rate of U. dioica was the highestcompared to that of F. lemanii, of O. vulgare and of T. repens(Table 1). The seed germination rate of O. vulgare was alsosignificantly higher than that of F. lemanii (Table 1). Overall, theseed germination rate was significantly higher in the control fromthe Luvisol than in the casts of A. chlorotica in the Rendosol and the Luvisol and in casts of A. rosea in the Histosol (Table 1). Presence inearthworm cast tended to decrease seed germination rates sincehigher germination rates were found in artificial casts from controlsoils than from casts (GLM, x2 = 418.2, df = 3, p = 0.033, n = 240;
