The uptake and accumulation of copper by Becium homblei (de Wild.)

The uptake and accumulation of copper by Becium homblei (de Wild.)

Duvig. and Plancke. New Phytol 68: 1081-1087

This labiate, indigenous to Zambia, was found to grow on soils containing up to 70 000 ppm Cu, and is capable of accumulating more than 100 ppm Cu in its leaves and roots. Serial extraction of plant tissues showed that much of the accumulated Cu was not in ionic form. An increase in total N occurred with an increase in Cu content and it is suggested that the Cu may be bound as a protein complex.
