benefits of permanent governance, the in situ
nature of the process, the low cost of treatment,
the environmental aesthetic compatibility,
and the ease of post-processing, phytoremediation
has received widespread recognition and attention
in both public and academic circles, and it has
become a promising soil remediation technique
(Chaney et al. 1997; Salt et al. 1998; Nouri et al.
2009). Many scholars in various countries have
made considerable researches on searching plants
of high biomass and super-accumulation of heavy
metals, nowadays ornamental plant have become
a new source of phytoremediation species for they
not can only be used for landscaping but also have
practical applications in air pollution monitoring
and control (Hemndez-Apaolaza et al. 2005). Taking
ornamental plants in the repair of heavy metal
polluted soils has important practical significance
(Zhou 2006); therefore this paper chose one popular
ornamental plant, Chlorophytum comosum in
Liliaceae Chlorophytum and made researches on
the Cd effect on its growth and Cd accumulation
which aims at clarifying its resistance mechanisms
and providing scientific basis for repairing Cdpolluted
soil by C. comosum.
