For revegetation of mine dumping sites, introduction tolerant plant species to tailings is needed. We compared initial shoot growth the plants grown in with that control Kanuma pumice evaluate tolerance among various species; one crop species, ine (Oryza sativa L. cv. Nipponbare); three yomogi (Artemisia princeps), medohagi (Lespedeza cuneate G. Don), and creeping red fescue (Festuca rubra L.); two native mizudokusa (Equisetum fluviatile L.) susuki (Miscanthus sinensis). The was significantly lower than for ine, yomogi, medohagi, but not susuki. evaluated whole-plant respiration mizudokusa, did observed significant difference between plants; however, Fe concentration roots higher all species. It probable high accumulation caused by induces reduction while does affects because their concentration. Effective use may help site.
