Abstract Background:Coexistence of polycylic aromatic hydrocarbons (PAHs) and heavy metals deleteriously threatens the quality of environmental health. Few reports uncover the mechanism of inoculation plants with Piriformospora indica for remediating PAH-metal co-contaminated soil by analyzing the chemical speciations of contaminants. This study investigated the influence of inoculation Medicago sativa with Piriformospora indica to remediate phenanthrene (kind of PAHs), and cadmium (one of heavy metals) co-contaminated soil by analyzing the plant growth, physiological parameters and chemical speciation in rhizospheric and non-rhizospheric soil. Results:The presence of P. indica significantly increased plants tolerance, Chlorophyll a, Chlorophyll b, maximum quantum efficiency of PSII photochemistry and electron transport rate values in phenanthrene and/or cadmium contaminated soil. P. indica inoculation in M. sativa root increased fluorescein diacetate activities in phenanthrene, cadmium and both of that co-contaminated soil, especially in non-rhezospheric soil. The presence of phenanthrene hindered the inoculated plant from accumulating cadmium to some extent; Whereas the presence of cadmium did not hinder the degradation of phenanthrene in both rhizospheric and non-rhizospheric soil after P. indica colonization. Although the poor bioavailability of cadmium in rhizospheric soil restricted the transportation into stem, P. indica colonization in plant efficiently increased cadmium accumulation in root in cadmium and phenanthrene co-contaminated soil. Conclusions: In conclusion, the work provides the theoretical basis that Piriformospora indica combined with Medicago sativa contributed to the remediation of PAH-Metal co-contaminated soil.

This study investigated the influence of the inoculation of Medicago sativa with P. indica to remediate soil co-contaminated with phenanthrene (a kind of PAH) and cadmium (a heavy metal) by analyzing plant growth, physiological parameters and chemical speciation in rhizosphere and nonrhizosphere soils. Results: The presence of P. indica significantly increased plant tolerance, chlorophyll a, chlorophyll b, maximum quantum efficiency of PSII photochemistry and electron transport rate values in phenanthrene- and/or cadmium-contaminated soil. P. indica inoculation in M. sativa roots increased fluorescein diacetate activities in soils contaminated with phenanthrene, cadmium or both, especially in the nonrhizosphere. The presence of phenanthrene prevented the inoculated plant from accumulating cadmium to some extent, whereas the presence of cadmium did not prevent the degradation of phenanthrene in either the rhizosphere or the nonrhizosphere after P. indica colonization. Although the low bioavailability of cadmium in the rhizosphere restricted its transportation into the stem, P. indica colonization in plants effectively increased cadmium accumulation in roots in soil co-contaminated with cadmium and phenanthrene. Conclusions: In conclusion, this work provides a theoretical basis for the use of P. indica combined with M. sativa for the remediation of PAH-metal co-contaminated soil.

Intercropping can increase the biomass of plants and reduce the accumulation of heavy metals in plants. However, the mechanisms of intercropping increasing plant biomass and resistance to heavy metals are still unclear. Therefore, the pot experiment had been conducted to investigate the effect of intercropping treatment on the growth of gramineous pasture ryegrass (Lolium perenne L.) and leguminous forage alfalfa (Medicago sativa L.) in metal-contaminated soil. Our results showed that intercropping alleviated inhibition of heavy metals to plant growth and increased nitrogen and chlorophyll contents in the shoots and roots. Moreover, the Pb concentrations in the shoots and roots of ryegrass and alfalfa in the intercropping were significantly lower than those in the monoculture. And, the contents of saccharase and alkaline phosphatase were significantly increased in the intercropping treatment. Additionally, the intercropping treatment could reduce the oxidative damage and increase enzymatic antioxidant activities to improve the resistance of plants in contaminated soil. The intercropping treatment can increase the resistance of plants to heavy metals through reduction of plant oxidative damage and increase of antioxidant activity. It could provide us with a strategy that intercropping of ryegrass and alfalfa can increase biomass and reduce the absorption of Pb on forage plants.

To study the cadmium accumulation characteristics of Solanum nigrum with different ploidies, the biomass, cadmium content and cadmium accumulation of diploid (Solanum photeinocarpum), tetraploid (Solanum photeinocarpum) and hexaploid (Solanum nigrum) were measured by a pot experiment. The results showed that the biomass of roots, stems, leaves and shoots of S. nigrum plants with different ploidy all ranked as follows: hexaploid > tetraploid > diploid. Cadmium content and cadmium accumulation in stems, leaves and shoots of hexaploid plants were significantly higher than those in tetraploid and diploid plants, and the cadmium translocation factor and translocation accumulation factor of hexaploid were the largest, too. Therefore, hexaploid S. nigrum had a highest ability to extract and transport cadmium, which can be used as an ideal plant for remediation of cadmium-contaminated soil.
