—Phytoremediation is becoming a potential method
for remediation of heavy metal contaminated soil. The aim of
this study is to discuss whether the sorrel absorbs copper (Cu)
from the soil, and whether arbuscular mycorrhizal fungi
（AMF） inoculation enhances its capacity of Cu uptake. The
experiment was conducted in plastic pots with three treatments:
control, 600 mg/kg Cu, and 600 mg/kg Cu plus 10 g AMF. The
results showed that the sorrel accumulated Cu when planted in
Cu contaminated soil. Furthermore, the more uptake Cu, the
more nitrogen (N) and phosphorus (P) was absorbed. When the
sorrel was under copper stress, its peroxidase (POD) and
catalase (CAT) activities increased, while superoxide dismutase
(SOD) activity decreased compared with the control.
Chlorophyll (Chl) content decreased under copper stress, but no
significant differences were observed in malondialdehyde (MDA)
content. Although Cu stress inhibited the activity of soil urease,
it didn’t affect activities of soil cellulose, soil sucrase, and soil
catalase. It also showed that AMF inoculation promoted the
growth of sorrel, enhanced the capacity of Cu, N, P, and
potassium (K) uptake, but it didn’t affect MDA and Chl content,
POD activity , and CAT activities of sorrel. However, SOD
activity was inhibited a little bit. The results also showed that
AMF enhanced the activity of soil urease, inhibited activities of
soil cellulose and soil sucrase. But it didn’t influence the activity
of soil CAT. It concluded that this sorrel was a Cu accumulating
plant and AMF inoculation improved its capacity of Cu uptake.
