METHOD FOR HYPERACCUMULATION OF METALS IN PLANT SHOOTS

摘要

The present invention provides methods by which hyperaccumulation of metals in plant shoots is induced by exposure to inducing agents. In preferred embodiments, manipulations that increase availability of metals to the plant are employed prior to application of the inducing agent. Effective inducing agents include conditions of low pH, chelators, herbicides, and high levels of heavy metals. Other phytotoxic agents are also useful. Application of multiple inducing agents results in synergistic effects.
