For this, non-deformed soil samples were collected, whichwere used in legume cultivation in a greenhouse.Experiments were carried out on the speciesSenna alata, Flemingia macrophylla and Mimosa debilis grown on two types of soil: AmazonianDark Earth (secondary forest and cultivated area) and Ultisol (secondary forest and cultivatedarea).In these experiments non-cultivated soils were used as control. Diversity access wasperformed using T-RFLP (Terminal Restriction Length Polymorphism). Two primers were usedfor Archaea (21-f-FAM, 958r). The restriction enzyme used was HhaI. The data obtained wereanalyzed using PCA (Principal Component Analysis). The results showed that the microbialcommunities’ richness was higher in the S. Allata rhizosphere in both soils with secondaryforest than in the rhizosphere of the other legumes and the non-cultivated control. Relativeabundance varied due to the presence of dominant T-Rfs in all treatments. With the PCAsupport it was possible to detach the Archaeal communities from the rhizosphere in the twosoil types. It is concluded that the rhizosphere e ect is in uenced by the species of legumecultivated and the soil type.See more from this Division: SSSA Division: Soil Biology and Biochemistry See more from this Session: Soil Biology and Biochemistry General Poster<< Previous Abstract | Next Abstract >>© 2017 - Copyright Information, Privacy Statement and Terms of Use American Society of Agronomy | Crop Science Society of America | Soil Science Society of America 5585 Guilford Road | Madison, WI 53711-5801 | 608-273-8080 | Fax 608-273-2021  Certi cation 608-273-8085 | Fax 608-273-2081
