Effect of Inoculation with Glomus versiforme on Cadmium Accumulation, Antioxidant Activities and Phytochelatins of Solanum photeinocarpum

摘要: The plant growth, phosphate acquisition, Cd translocation, phytochelatins (PCs) production and antioxidant parameters [superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (POD), ascorbate (APX), glutathione reductase (GR), (GSH), (ASA) malonaldehyde (MDA)] were investigated in Cd-hyperaccumulator Solanum photeinocarpum inoculated with Glomus versiforme BGC GD01C (Gv) Cd-added soils (0, 5, 10, 20, 40 mg kg-1 soil). Mycorrhizal colonization rates generally high (from 77% to 94%), hardly affected by Cd. Gv significantly enhanced P growth total uptakes both shoots roots of S. at all levels. Meanwhile, symbiosis increased concentration the roots, decreased levels, which indicates that could promote phytostabilization enhancing accumulation inhibit its translocation “dilution effects” linked an increase dry matter yield a reduced partitioning shoots. Moreover, improvement CAT, POD APX activities leaves mycorrhizal plants infers helped relieve oxidative damage biomolecules Cd-contaminated soil. evident decline MDA content evidently improved activities, enhancement PCs suggests Gv-inoculated may be more efficient phytotoxicity. Therefore, possible mechanisms phytotoxicity alleviation can concluded as POD, plants.
