Arbuscular mycorrhizal fungi in wheat grown in copper contaminated soil

At high soil concentrations, copper (Cu) is toxic to plant development. Symbiosis carried out between microorganisms and species are alternatives minimize toxicity in contaminated soil. The present study aimed select of arbuscular mycorrhizal fungi for the development wheat plants experimental design was completely randomized a 4 × 6 factorial arrangement, with four sources inocula: three mycorrhizae (Acaulospora colombiana, Gigaspora Margarita Rhizophagus clarus) one without inoculum (control), six doses (0, 80, 160, 240, 320, 400 mg kg-1), seven replications. Plant height, root length, volume, dry mass, specific surface area, average diameter, root, shoot grain Cu content colonization rate were evaluated. Root mass negatively affected by isolates Acaulospora Colombiana provide greater length area lower content. Mycorrhizal Colombiana, clarus results shoots grains.
