| ABSTRACT: The objective of this study was to evaluate the effects of inoculation with different arbuscular mycorrhizal fungi native to Cerrado, associated with the application of colonization stimulant (7-hydroxy, 4’-methoxy-isoflavone) at the initial growth of cotton and maize plants in a greenhouse. The experiment was carried out in a completely randomized design and 7x2 factorial scheme, with five species of arbuscular mycorrhizal fungi and combined inoculation (uniting all species in equal proportion) and native fungi, in the presence and absence of colonization stimulant in maize and cotton crops. Shoots dry matter (SDM), roots dry matter (RDM), mycorrhizal colonization and accumulation of calcium, zinc and phosphorus in the SDM were evaluated at... |

| Este trabalho foi realizado com o objetivo de avaliar a eficiência de absorção de fósforo em doze genótipos de milho na presença e na ausência de inoculação com fungo micorrízico arbuscular. Para tanto, foi instalado um experimento em casa de vegetação no Centro de Ciências Agrárias e Biológicas da Universidade Federal de Goiás, em Jataí, Goiás, com delineamento em blocos ao acaso com três repetições em fatorial 12x2x2. Os genótipos foram: AG9010, P30K75, AG8060, P30P70, AG405, P30F33, AG7000, BANDEIRANTE, EMGOPA501, BALU178, DINA657 e 2C599, cultivados sob duas doses de fósforo (10 e 100mg kg-1 de P na solução do solo) na presença ou na ausência de micorrização com Glomus etunicatum. Foi verificada diferença entre os genótipos na produção de matéria seca... |

| ABSTRACT The benefits of mycorrhization occur with the growth of hyphae in colonized roots by promoting an increase of the contact surface which improves the initial growth due to a better absorption of water and nutrients. The objective was to evaluate the effect of arbuscular mycorrhizal fungus Rhizophagus clarus inoculation over the initial development and nutritional response of six genotypes of Coffea arabica L. Six genotypes of Coffea arabica L. were used (MGS Aranas, H29-1-8-5, Red Catuai IAC 144, IPR 100, Catigua MG2, Paraíso H 419-1) and with arbuscular mycorrhizal fungus - AMF: Rhizophagus clarus and without the application of the fungus. For the production of coffee seedlings, seeds were placed to germinate in plastic trays with sterile sand.... |

| Apesar da existência de informações descritivas sobre solos arenosos das regiões tropicais, àquelas referentes ao manejo e conservação são escassas. No presente estudo, objetivou-se avaliar as alterações dos atributos físico-hídricos de um Neossolo Quartzarênico Órtico em função do uso e manejo com vistas à definição de sistemas de manejo sustentáveis. O estudo foi conduzido no município de Mineiros, GO, em áreas submetidas a cinco sistemas de uso e manejo do solo, sendo: Pastagem (PAS), Plantio direto de Soja (PDS) e de milho (PDM), Integração agricultura-pecuária (IAP) e cerrado nativo (CER). Coletaram-se cinco amostras por sistema nas camadas de 0 a 10 e 10 a 20 cm no inverno de 2005 e verão de 2006, para avaliação da densidade do solo, micro e... |

| Phosphorus (P) sorption by soils is a phenomenon that varies depending on soil characteristics, influencing its intensity and magnitude, which makes it a source or drain of P. The objective of this study was to determine the Maximum Phosphorus Adsorption Capacity (MPAC) and desorption of P from soils under native Savanna Brazilian and verify the correlation between MPAC and P Capacity Factor (PCF) with the chemical and physical properties of these soils. The study was conducted in seven soils under native Savannas. The Langmuir isotherms were adjusted from the values obtained in sorption assays, being evaluated the MPAC, the energy adsorption (EA) and PCF, which was calculated according to the levels of P-adsorbed and P-sorbed. Values of MPAC were... |

| ABSTRACT Arbuscular mycorrhizal fungi (AMF) interact symbiotically with most plant species, facilitating revegetation of areas under rehabilitation. The aim of this study was to evaluate the inoculum potential, density, and diversity of AMF spores in five environments, as well as the relation of species with soil properties. Soil samples were collected in five environments in a mining area and its surroundings in the Quadrilátero Ferrífero, Minas Gerais (Brazil): tailings piles in rehabilitation with grass, canga, Cerrado, native forest, and eucalyptus plantation; these samples were subjected to chemical and physical analyses. Spores were directly extracted from field samples and from trap cultures (TCs) established in two locations in the Southeast and... |

| ABSTRACT The production of Coffea arabica L. clone seedlings through the somatic embryogenesis technique is one of the alternatives of greatest demand for coffee producers. However, clones can face difficulties related to acclimatization carried out under greenhouse conditions, which can increase the production costs. A tested alternative with promising results is inoculation with arbuscular mycorrhizal fungi (AMF) during the seedling acclimatization process. Thus, this study aimed to promote the improvement of the seedling production process through somatic embryogenesis associated with inoculation with AMF. For the production of the clones, seedlings were used in the phase when they presented four pairs of leaves (Clone 1 “Fruiting red Catucaí” and Clone... |

| ABSTRACT Soil structure, which is defined by the arrangement of the particles and the porous space forming aggregates, is one of the most important properties of the soil. Among the biological factors that influence the formation and stabilization of soil aggregates, arbuscular mycorrhizal fungi (AMF) are distinguished due to extrarradicular hyphae and glomalin production. In this context, the objective of this study was to evaluate different AMF (Acaulospora colombiana, Acaulospora longula, Acaulospora morrowiae, Paraglomus occultum and Gigaspora margarita) associated with Urochloa brizantha (A. Rich.) Stapf on soil aggregate stability. The study was conducted in a completely randomized design, using an Oxisol and autoclaved sand 2:1 (v/v), with seven... |
