Copper accumlation by polygonum microcephalum D.Don from copper mining spoils in Yunnan Province
|
Abstract:
It was found that P.microcephalum grows extensively on copper mining spoils in Yunnan Province as a representative of typical high\|elevation copper flowers.Plants and their associated soil samples collected from several copper mines in the Province were analyzed.The results showed that P.microcephalum can grow well on mining spoils rich in copper but with medium nutrient supply.Copper concentration in the roots tended to increase with copper increase in the substrates,however,the relation between copper in the leaves and soil copper is not clear.It is suggested that P.microcephalum may possess the potential for phytostabilization of metal\|contaminated soils and for biogeochemical prospecting.
