Abstract In soil biota, higher and enduring concentration of heavy metals like cadmium (Cd) is hazardous and associated with great loss in growth, yield, and quality parameters of most of the crop plants. Recently, in-situ applications of eco-friendly stabilizing agents in the form of organic modifications have been utilized to mitigate the adverse effects of Cd-toxicity. This controlled experiment was laid down to appraise the imprints of various applied organic amendments namely poultry manure (PM), farmyard manure (FYM), and sugarcane press mud (PS) to immobilize Cd in polluted soil. Moreover, phytoavailability of Cd in wheat was also accessed under an alkaline… More >

Abstract Arbuscular mycorrhizal fungi (AMF) can improve plant tolerance to several abiotic stresses, including heavy metals, drought or salinity exposure. However, the role of AMF in alleviation of soil cadmium (Cd)-induced toxicity to plants is still largely unknown. In this study, Cd speciation in soil and subcellular distribution of Cd were used to characterize the roles of application AM fungi in the alleviation of Cd toxicity in alfalfa plants. Our results showed that the addition of Glomus mosseae in Cd contaminated soil (10 mg/Kg) significantly increased soil pH, cation exchange capacity (CEC) and organic matter in rhizosphere soil with Medicago truncatula… More >

Abstract We conducted pot experiments on the cypress Thujopsis dolabrata (Linn. f.) Sieb. et Zucc. in order to study the interaction of silicon (Si) and root exudates on cadmium (Cd) bioavailability in the rhizosphere,. Each variety was planted with 100 mg/kg Cd and/or 400 mg/kg Si for 210 days. The results showed that adding Si increased Cd tolerance in T. dolabrata, but that the mechanism was specifical. In T. dolabrata, Si did not prevent Cd translocation from roots to shoots, and it significantly enhanced Cd accumulation without inhibiting growth. Moreover, Si mobilized Cd from the rhizospheric soil by stimulating phenolic exudation… More >
