We studied the allelopathic effects of Artemisia sacrorum on vegetation succession in typical grassland on Yunwu Mountain. The effects of root exudates, rhizosphere soil extracts and leaf and stem extracts from A. sacrorum were assayed on seed germination, radicle length, and coleoptile length of 4-dominant grassland species (Stipa bungeana, S. grandis, Thymus mongolicus, and Leymus secalinus) and for autotoxicity on A. sacrorum. The grassland species showed different responses to the extracts and root exudates of A. sacrocum. At the same concentration, the methanol extracts had greater effects on Acceptor planta than aqueous extracts. The effects of the alkaloids obtained from A. sacrorum leaf and stem extracts were significantly differed than other fractions. Our results suggested that allelopathy of A. sacrorum shapes the botanical composition of grasslands on Yunwu Mountain.
