Copper Accumulation and Tolerance of Chlorophytum comosum

Abstract:

In this study, Copper (Cu) tolerance in Chlorophytum comosum was tested by pot-planting. The results showed that the tolerance index (TI) of C. comosum was above 100 in soil Cu concentration of 50mg·kg^-1. With the increase of Cu concentration in soil, the MDA content increased, but had no significant differences with the control until 500mg·kg^-1. The value of chlorophyll a/b had no significant differences with the control in all treatments. Meanwhile, the bioaccumulation coefficient (BC) and translocation factor (TF) value of C. comosum were 1.287 and 0.687 respectively in Cu concentration of soil up to 500mg·kg^-1. For the advantages of high tolerance, high accumulation and high ornamental value, C. comosum may be a potential Cu-accumulator and have tremendous application value in the treatment of Cu-contaminated soils.
