The effects on the growth, physiological
indexes and the cadmium (Cd) accumulation in
Chlorophytum comosum under Cd stress were
examined by pot-planting. The results showed
that the tolerance index (TI) of C. comosum
were all above 100 in soil Cd concentration of
100 mg kg−1. TheO−
2• production rate and electrical
conductivity of C. comosum were significantly
positively correlated to Cd adding-concentration
while the MDA content increased and had significant
differences with the control. The activities
of SOD, CAT, and POD all rose significantly in
lower Cd concentration and the Cd threshold of
them were around 10, 50 and 20 mg kg−1, respectively.
The Cd in C. comosum root and aboveground
part reached 1,522 and 865·5 mg kg−1,
respectively, in Cd concentration of soil up to
200 mg kg−1. For the advantages of high tolerance,
high accumulation, and high ornamental value,
C. comosum may have tremendous application
value in the treatment of Cd-contaminated soils.
