| ABSTRACT This research evaluated the changes on populations of culturable N-fixing free bacteria (NFFB) and P-solubilizing bacteria (PSB), as well as on the root nodulation by native rhizobia, the root colonization and spore number of arbuscular mycorrhizal fungi (AMF), in the rhizosphere of Clitoria ternatea and Brachiaria brizantha grown in mesocosms contaminated with crude oil (0, 3000, 6000, 9000, and 12000 mg kg-1), for 240 days. After 24 h of soil contamination, the highest populations of NFFB and PSB (5.5 and 4.9 LogUFC, respectively) were found in control, and the lowest populations were obtained at 12000 mg kg-1 (5.1 and 4.2 LogUFC, respectively). In contrast, at 60 and 240 days, the control showed lower populations of NFFB and PSB (5.4 and 4.8... |

| Schinopsis brasiliensis is an endangered tree species found in the Caatinga biome. It presents a characteristic slow development and difficult propagation, although it has been traditionally exploited in the region. Application of arbuscular mycorrhizal fungi (AMF) and phosphorus (P) fertilization may be beneficial to S. brasiliensis development at the seedling stage, which at the same time may help species conservation and the recovery of degraded areas in the Caatinga biome. We assessed the response of S. brasiliensis to AMF inoculation (Claroideoglomus etunicatum and Acaulospora longula) and P fertilization (0, 12, 24, and 48 mg dm−3 addition of P2O5). S. brasiliensis responded positively to both AMF inoculation and P fertilization. At low P... |

| The storage structures of spores of Gigaspora margarita Becker & Hall, an arbuscular mycorrhizal fungus, were analyzed by a transmission electronic microscope (TEM) and electron energy loss spectroscopy (EELS). The spores were hydrated, cryofixed using high pressure freezing, submitted to freeze substitution, embedded and prepared for TEM observations. The cryotechniques revealed that the storage structures in the spores are composed of lipids, electron dense granules (EDG), protein bodies and glycogen particles. The EELS detected the presence of nitrogen (N) and carbon (C) in these storage structures and in Bacteria-like organisms (BLO). Some amount of P was detected in the vacuoles and in BLO. The TEM and EELS techniques indicate the presence of... |

| In this study, we evaluated the growth of the liverwort Lunularia cruciata, inoculated or not with the arbuscular mycorrhizal fungi (AMF) Glomus proliferum (15 spores per Petri dish), in Strullu-Romand Variant (SRV) medium modified and enriched with humic acid (HA) at different concentrations (0, 20, 40 and 80 mg C L−1), as well as the sporulation of the AMF. We assessed the absolute growth rate (AGR) and relative growth rate (RGR) at inoculation, as well as at 7, 14, 21, 28, 43, 52 and 60 days after inoculation (DAI), whereas we assessed sporulation at 25, 43, 60 and 70 DAI. The main determinant of L. cruciata growth was the presence of AMF. With and without G. proliferum inoculation, respectively, the AGR peaked at 39 and 42 DAI, and the RGR was 0.0474... |

| O sistema de cultivo de arroz predominante no Brasil, o de terras altas, fica na dependência da precipitação pluvial e de sua distribuição. Determinadas práticas ou distúrbios, que atuam sobre o solo, levam a alterações que os microrganismos, por ser sensíveis, podem detectar. O trabalho objetivou estudar as alterações microbiológicas (carbono da biomassa microbiana (CBM)) e do CO2 (C-CO2) liberado, do quociente metabólico (qCO2) e micorrização), fertilidade do solo e produtividade do arroz de terras altas, cultivado sob diferentes manejos de solo e água. A cultivar utilizada foi a BRS Talento, e o delineamento experimental foi o de blocos casualizados, com quatro repetições. Os tratamentos foram arranjados em fatorial de três manejos de solo: plantio... |

| The seasonal dynamics of Arbuscular Mycorrhizal Fungi (AMF) was investigated in the rhizosphere of two fruit species in a terra firme (upland) ecosystem in Central Amazonia. Two host species (Theobroma grandiflorum and Paullinia cupana) and nine sampling months (August, September and December/1998, February, April, May and December/1999, February and May/2000) were studied in a completely randomized design, with five replications, set in a 2 x 9 factorial experiment. Soil (0-20 cm depth) and root samples were collected between August 1998 and May 2000. The mean percent colonization of AMF for both species reached maximal values in February and May 2000 (rainy season). In April and May 1999, February and May 2000 (rainy season) the highest AMF spore numbers... |

| To optimize nursery practices for efficient plant production procedures and to keep up to the ever growing demand of seedlings, identification of the most suitable species of arbuscular mycorrhizal fungi (AMF), specific for a given tree species, is clearly a necessary task. Sixty days old seedlings of Neem (Azadirachta indica A. Juss) raised in root trainers were inoculated with six species of AMF and a mixed inoculum (consortia) and kept in green house. Performances of the treatments on this tree species were evaluated in terms of growth parameters like plant height shoot collar diameter, biomass and phosphorous uptake capabilities. Significant and varied increase in the growth parameters and phosphorous uptake was observed for most of the AMF species... |

| The seasonal change and host preference of arbuscular mycorrhizal (AM) colonization and community composition of five common plant species Agropyron cristatum, Anemarrhena asphodeloides, Cleistogenes squarrosa, Leymus chinensis, and Stipa grandis in the Inner Mongolia steppe were investigated. The AM root length colonization rates were different among the five plant species and were generally high in early (May and June) and late (September) growth seasons and low in August. A total of 18 AM fungal species representing five genera were isolated from rhizosphere soils of the five plant species, and most AM fungi had not host specificity, except that Acaulospora sp., Glomus constrictum, G. diaphanum and Glomus sp. showed a certain degree of host preference.... |

| ABSTRACT: The objective of this study was to evaluate the physiological and biochemical mechanisms of adaptation of Hyptis suaveolens under osmotic stress due to salinity inoculations with a mycorrhizal fungal species. H. suaveolens seeds were germinated in polyethylene pots containing a substrate associated with or without arbuscular mycorrhizal fungi (AMF). After plant formation, treatments were treated with different salt concentrations (0.0, 35, 70, and 105 mM) and fungi (control and two types of AMF), totaling 12 treatments with three replicates. The experimental design used randomized blocks in a 4 x 3 factorial scheme, totaling 12 treatments with three replicates each. Salinity affected all measured physiological and biochemical variables, and the... |

| Los hongos micorrízicos arbusculares (HMA) forman una asociación simbiótica con las raíces de las plantas, favoreciendo un incremento en la asimilación de nutrientes del suelo. Los HMA colonizan la mayoría de los cultivos agrícolas; entre ellos, el cultivo del papayo presenta alto grado de dependencia micorrízica. Sin embargo, se cree que esta asociación es afectada por las prácticas de manejo utilizadas. Por lo que, en este trabajo se estudió la diversidad y distribución de especies de HMA así como la colonización y potencial infectivo de éstas en huertas de papayo bajo diferente manejo de producción en Isla, Veracruz. Como resultado de esta investigación, se presenta esta tesis estructurada fundamentalmente en cuatro capítulos. El primero,... |
