Abstract
In order to supply a theoretical evidence for repairing the heavy metal Cu polluted soil,this paper studied the effects of Cu on the peroxidase isoenzymes,plant height,chlorophyll content and membrane permeability in Helianthus tuberosus leaves.The results showed that compared with the control,7 bands of POD isoenzymes(P1-P7)were observed in leaves of H.tuberosus seedlings after Cu treatment,including two new bands(P1 and P2).The enzyme activities increased with the intensified band color when the concentration of Cu increased.Low concentration Cu(5 mg/L) stimulated the growth of H.tuberosus seedlings.It significantly increased plant height,chlorophyll content and membrane permeability.The high-level Cu treatment of H.tuberosus inhibited plant height,chlorophyll content and membrane permeability,which caused different levels of injury.
