??OBJECTIVE To study preliminarily the cadmium absorption and accumulation in Ligusticum Wallichii to provide a scientific basis for solving the problem of cadmium excess. METHODS The aboveground and underground parts of Ligusticum Wallichii in different growth periods and the rhizosphere soil were collected from Aoping Town, Pengzhou City and Yongshou Town, Meishan City. The cadmium content was determined, and the enrichment coefficient and transfer coefficient were calculated. RESULTS The average cadmium content in the underground part was 77.21% higher than that in the aboveground part. The cadmium enrichment coefficients and cadmium transfer coefficients of different parts were both greater than 0.5, and the enrichment coefficient of the underground part was 64.75% higher than the aboveground part. CONCLUSION Ligusticum Wallichii has a certain capacity to absorb and transfer cadmium, and most cadmium is enriched in the medicinal roots. |
