Progress in the Study of the Absorption

Ramie ( Boehmeria nivea ) is notable for its ability to accumulate and adsorb cadmium from heavy metal-contaminated soil. The accumulation of cadmium is more pronounced at a low cadmium concentration in the soil, and decreases with increase in cadmium concentration because of the effects of cadmium toxicity. In this review, the absorption, accumulation, and tolerance to cadmium of ramie is summarized. The existing knowledge gaps and prospects for utilization of ramie are noted to provide a theoretical foundation for future research on the utility of ramie for remediation of heavy metal-contaminated soil and for ramie breeding.
