Gibberellic acid (GA3) is an important hormone, which controls plant's growth and development. Solid State Fermentation (SSF) allows the use of agro-industrial residues reducing the production costs. The screening of strains (four of Gibberella fujikuoroi and one of Fusarium moniliforme) and substrates (citric pulp, soy bran, sugarcane bagasse, soy husk, cassava bagasse and coffee husk) and inoculum preparation study were conducted in order to evaluate the best conditions to produce GA3 by SSF. Fermentation assays were carried out in erlenmeyers flasks at 29°C, with initial moisture of 75-80%. Different medium for inoculum production were tested in relation to cells viability and GA3 production by SSF. F. moniliforme LPB 03 and citric pulp were chosen for... |

Un alto porcentaje de mortandad se presenta en pinos que son transplantados de vivero a campo, debido a que no poseen en sus raíces hongos ectomicorrízicos los cuales forman simbiosis obligada con los pinos de forma natural en los bosques. Estos hongos facilitan la absorción de nutrimentos y agua, además de estimular su crecimiento. Debido a la importancia de los hongos ectomicorrízicos, el presente trabajo evaluó el efecto en crecimiento, peso seco, porcentaje de colonización y contenido nutrimental de la inoculación de seis especies ectomicorrízicas comestibles de los géneros Laccaria y Hebeloma en Pinus patula y P. pseudostrobus, en condiciones de invernadero. Las especies inoculadas fueron previamente caracterizadas. Después de 397 días de la siembra... |

O presente trabalho teve como objetivo determinar degradabilidades in situ da matéria seca (MS), fibra em detergente neutro (FDN) e ácido (FDA) da cana-de-açúcar in natura (CF) ou ensilada (SC) e da silagem de milho (SM) em diferentes ambientes ruminais, utilizando a técnica in situ macro-bag. Foram utilizadas duas vacas canuladas, alimentadas com rações formuladas de maneira a serem obtidos diferentes ambientes ruminais, de acordo com os volumosos: CF ou SC. A degradabilidade in situ dos volumosos foi avaliada utilizando-se sacos com poros de 50 µm, medindo 20 x 40 cm, sendo os volumosos incubados in natura nos horários 0, 12, 24, 48, 72, 96h. Os ambientes ruminais consistiram de um arranjo hierárquico 3 x 2 (3 forragens x 2 ambientes ruminais). Amostras... |

Nitrogen removal in soybean grains at harvest may exceed biological N2 fixation, particularly if grain yields are as high as typically achieved on "Terra Rossa" soils of Eastern Paraguay. Applying N fertilizer or coating seeds with rhizobial inoculants that enhance nodulation may represent a way of balancing the N budget. However, the effects of such treatments appear to be highly site-specific. The objective of this study was to examine the effects of N application (N) and rhizobial inoculation (I) on nodulation, N accumulation and soybean yields in Eastern Paraguay. Field experiments were conducted in two consecutive soybean seasons. Dry conditions in the first year delayed sowing and reduced plant number m-2 and pod number plant-1. Grain yields were... |

ABSTRACT Anaerobic biodigestion of solid and semi-solid wastes has been widely used for the treatment of these residues and methane production; however, during the process (more specifically in the acidogenic phase), there is a tendency of pH reduction, an unfavorable condition to methanogenic bacteria. Thus, the present work aims to evaluate the methanization potential of an agroindustrial anaerobic granular sludge (AIS) from UASB (Upflow Anaerobic Sludge Blanket) reactor, individually and biodigested with food waste (FW) from the University Restaurant of the Federal University of Pernambuco with buffering agent (AIS + FW + b) and without it (AIS + FW). After the laboratory tests, the AIS + FW + b configuration obtained a cumulative methane production... |

Sphaeropsis sapinea is one of main pathogens that causes losses in commercial plantations of Pinusspp. Studies for control based on genetic resistance can be done by inoculating different monosporic isolates onpine populations and selectioning the resistant individuals. This work describes a methodology for pycnidia production in vitro and S. sapinea monoconidial cultures, using an agar-water medium with sterile pine needles. Four S. sapinea isolates were tested e pycnidia and mature conidia were observed after 14 days of incubation, under continuous fluorescent light, in BOD, at 25 °C. Pycnidia were triturated in sterile water and conidia germinated after two hours of incubation in water-agar, in BOD, at 25 °C. Germinated conidia formed colonies which... |

Abstract In order to obtain an arbuscular mycorrhizal fungi (AMF) native inoculum from Sierra de Moa and determine the most appropriate conditions for its big scale production, four light and temperature combinations were tested in three plant species (Calophyllum antillanum, Talipariti elatum and Paspalum notatum). Growth and development parameters, as well as the mycorrhizal functioning of the seedlings were evaluated. The natural light treatment under high temperatures (L-H) was the most suitable for the growth and development of the three plant species, showing the highest total biomass values, mainly of root, and a positive root-shoot ratio balance. This treatment also promoted higher values of root mycorrhizal colonization, external mycelium and AMF... |

Assays were conducted to assess the number of Beauveria bassiana (Bals.) Vuill. conidia on Diatraea saccharalis F. (Lepidoptera: Pyralidae), Nezara viridula (L.) and Piezodorus guildinii (Westwood) (Hemiptera: Pentatomidae) corpses maintained at different levels of relative humidity (RH) (75%, 80%, 85%, 90% and 100%) and temperatures (22°C, 26°C, 30°C and 34°C) during five days. The isolates produced conidia when exposed to RH from 75% to 100%. Conidiogenesis was incipient at 75% RH on D. saccharalis larvae, but did not occur on N. viridula and P. guildinii. In ideal conditions of RH and during 10 days, mathematical equations were developed to estimate the number of conidia produced by isolates ARSEF 933 and ARSEF 2515. Conidia number were shown to be... |
