Abstract: Through solution culture and soil culture experiments,effects of Tongling copper mine tailings on seed germination and seeding growth of five legumes species were studied in this paper.The results showed that the seeds of five legumes species could germinate in the normal and acidified tailings extracted solution,but germination percentage was lower than that under control.It indicated that tailings extracted solution had inhibition effect on seed germination,however,acidified tailings extracted solution promoted absorbing water of the seeds in early stage.In five amelioration substrates between tailings and soils,the tailings also inhibited seed germination of the five species.No dead seedlings of Glycine max, Phaseolus angularis, P.calacaratus were found within 70 days.
