摘要： Distribution and mobility of nine mineral elements (K, Ca, Na, Mg, Fe, Zn, Cu, Se, and Cr) in cultured Gentiana rigescens and its root zone soil were determined by atomic absorption spectroscopy. G. rigescens materials were planted under tea and white papaya trees in Yun County and Yongde of Lincang area in Yunnan Province of China. The results showed that G. rigescens and its soil were high in K, Ca, Fe, and Mg. The concentrations of Na and Mg in the soil were significantly lower than that in the plants. However, the concentrations of Fe, Cu, Se, and Cr were significantly higher in soils than that in the plant parts. G. rigescens roots showed high accumulation ratios for Na, Mg, and K, but low accumulation ratios for Fe, Cu, Se, especially for Cr. Transfer coefficients indicated G. rigescens might be a good accumulator for Ca.
