Abstract

The effects of various concentrations (0, 50, 100, 500, 1000 and 3000 ppm) of copper (Cu) on the spore germination, growth and copper accumulation in Pteris vittata were studied. Results indicated that spores of P. vittata were able to germinate and develop up to 3000 ppm Cu. The result of EDX analysis showed that the highest concentration of Cu, irrespective of the levels of concentration, was detected in the stipe (0.67% of dry weight), and it was in an amount not meeting the 1000 pp, standards of hyperaccumulating plants. This shows that P. vittata is not a Cu hyperaccumulator, but a Cu tolerant plant independent of its known as hyperaccumulation activity.
