【Abstract】 In order to understand the absorption and enrichment of Se in typhaceae,parts of the typhaceae grown in the soil covered by Se solution were analyzed.Se concentrations in the plants are much higher than those in the soil,indicating an enrichment of Se in the typhaceae.The largest enrichment was observed in the root hair of the plant.We also observed absorption of P and N by typhaceae from polluted water.更多还原
