Renovation of annual grassland in Japan by volunteer grasses

摘要：

Temperate perennial grasses from Europe,such as Dactylis glomerata L.and Festuca arundinacea Schreb.,are the main grasses sown in meadows of Japan.However, since the Kyushu Region in southwestern Japan is warmer, tropical annual grasses such as Echinochloa crus-galli(L.) Beauv.and Digitaria adscendens (H.B.K.) Henr. have spread in meadows from summer to autumn.Meanwhile, volunteer Lolium multi f lorum Lam.,which is a temperate annual grass, spreads from spring to early summer in meadows of the Kyushu Region.In this way, tropical and temperate annual grasses alternate in dominance as volunteer grasses.We investigated the seasonal change of vegetation in an annual meadow and the characteristics of germination and dormancy for Echinochloa crus-galli, Digitaria adscendens and Lolium multi florum.
