Effect of inoculation with AM fungi on DBP-pollution of plant

Abstract

Abstract: In greenhouse, taking DBPas the object and taking Pigna sinensis inoculated respectively with AM fungi Aculospora lavis and Glomus caledonium as the host plants, a pot experiment was carried out to study the effect of inoculated AM fungi on the dynamics of plant DBP-pollution. The experiment lasted 60d. The results indicated that inoculation with AM fungi could restrain plant from absorbing DBP. Although AM fungi were affected by DBP, they played important roles in decreasing the DBP uptake by plant and the translocation of DBP from roots to aboveground part of plant. After inoculation with AM fungi, the final concentrations of DBP in plants inoculated respectively with Aculospora lavis and Glomus caledonium were decreased, to significant level (P<0.01) with maximum decrease ratios reaching up to 32.7% and 21.7%, respectively when soil-applied DBPconcentration was 4mg穔g^-1, and to significant level (P<0.05) with maximum decrease ratios reaching up to 30.5% and 30.0%, respectively when soil-applied DBPconcentration was 100mg穔g^-1.The translocation of DBPfrom roots to aboveground part of plant was also inhibited by inoculated AM fungi. Therefore, AM was helpful to decrease plant DBP-pollution.

Key words: AM fungi, DBP, Pollution, Translocation, Camellia oleifera, minirhizotron, fine root, variety.
