Abstract:In order to study the effects of Arbuscular mycorrhizal Fungi(AMF) inoculation on the tolerance and accumulation characteristics of celery growing in the cadmium(Cd) pollution soil and clarify the mechanism, a celery cultivar ’ Huanghou’ was selected as experimental material and the effects of five different kinds of AMFs include Glomus versiforme(Gv), Glomus intraradices(Gi), Glomus mosseae(Gm), Glomus aggregetum(Ga) and Glomus etunicatum(Ge) on the plant growth, chlorophyll contents, MDA contents, activities of antioxidant enzyme, the accumulation and allocation pattern of Cd of celery plant under Cd stress were investigated. The results showed that under the Cd stress conditions, the growth of celery was significantly improved with AMF inoculation, the chlorophyll content and activities of antioxidant enzymes(SOD, POD, CAT) were significantly increased, but the MDA content was significantly decreased. Cd absorption of celery was significantly improved with AMF inoculation, the Cd content in root, retention rate(RR) and bioconcentration factor(BCF) were significantly increased, but the Cd content in stem and leaf, translocation factor(TF) were significantly decreased. The best effect of treatments was Glomus intraradices(Gi) inoculation, compared with CK. The plant height, stem diameter, dry weight, actives of antioxidant enzymes(SOD, POD, CAT), the Cd content in root, translocation factor(TF) and bioconcentration factor(BCF) were increased by 49.18%, 50.74%, 41.93%, 18.63%, 51.48%, 48.19%, 51.72%, 117%, 102.44% and 117.78%, but the MDA content, Cd content in stem, Cd content in leaf and translocation factor(TF) were decreased by 30.37%, 36.42%,43.27% and 71.19%. The MDA content had the greatest correlation with the degree of CD stress. The results can provide reference for Cd-tolerant cultivation of celery and remediation and utilization of Cd polluted soils.
