| La calidad de las semillas es un elemento de suma importancia para los productores, por tal motivo las pruebas de calidad física y fisiológica son primordiales para estimar eficacia. En el presente estudio se efectuaron dichas pruebas en semillas de 18 híbridos comerciales de maíz de los Valles Altos Centrales de México. Se utilizaron el laboratorio y almaciguero del programa de semillas del Colegio de Postgraduados, además de cuatro localidades del Estado de México. En laboratorio se midieron las variables: porcentaje de germinación al primer conteo, contenido de humedad, peso volumétrico, análisis de pureza, condición del pedicelo, peso de mil semillas y se reclasificó a la semilla en seis tamaños. En almaciguero se sembró semilla en dos condiciones... |

| ABSTRACT The study aimed to evaluate the initial development, as well as, the chemical characteristics of lettuce plants grown in substrate with high concentrations of bioagent (trichoderma). A completely randomized design with four replicates was used. The treatments, applied to a substrate composed of a blend of vermicompost and commercial substrate, were established by the following doses of the commercial product ICB Nutrissolo Trichoderma: T1) 0.0; T2) 1.0; T3) 2.0; T4) 4.0; T5) 8.0 and T6) 16.0x1011 conidia kg-1 of product. After inoculation, the substrate was placed in trays, where 50 lettuce seeds were sown on each replication. Plants were thinned after emergency stabilization, maintaining ten seedlings per tray. At 28 days after sowing, the... |

| The experiment was conducted in a greenhouse at the Universidade Federal do Espirito Santo, in Alegre, Espirito Santo state, Brazil, to evaluate the broccoli production depending on the seed production system and organic and mineral fertilization. Seeds of the broccoli cultivar Ramoso Piracicaba were originated from lots of seed obtained in an organic and conventional production system. The experimental design was of randomized blocks, with four replications in a factorial arrangement combination of the lots, 2x5 (organic and mineral fertilized seeds) and substrates [S1 (soil + sand + manure), S2 (soil + sand + manure + NPK), S3 (soil + sand + manure + Fertium® 10 g L-1), S4 (soil + sand + manure + Fertium® 30 g L-1) and S5 (soil + sand + manure + Fertium®... |

| RESUMO: O objetivo deste trabalho foi avaliar os efeitos do tempo de imersão e da concentração de ácido giberélico na quebra de dormência das sementes de diferentes matrizes de pequi. Consistiu em dois experimentos conduzidos em safras distintas: no primeiro, os caroços oriundos da mistura de várias plantas foram submetidos à imersão por dois e quatro dias, em três concentrações de GA3 (0,500 e 1000 mg.dm³). O delineamento experimental foi inteiramente ao acaso, com oito repetições de 50 sementes por parcela, em esquema fatorial 3x2, mais a testemunha constituída de caroços não tratados. O segundo foi conduzido na safra seguinte, sendo os caroços colhidos e mantidos separados por planta-matriz (sete ao todo) e submetidos à imersão por dois e quatro dias em... |

| Global changes linked to increases in temperature and ocean acidification, but also to more direct anthropogenic influences such as aquaculture, have caused a worldwide increase in the reports of Vibrio-associated illnesses affecting humans and also animals such as shrimp and molluscs. Investigation of the emergence of Vibrio pathogenesis events requires the analysis of microbial evolution at the gene, genome and population levels, in order to identify genomic modifications linked to increased virulence, resistance and/or prevalence, or to recent host shift. From a more applied point of view, the elucidation of virulence mechanisms is a prerequisite to devising prophylactic methods to fight infectious agents. In comparison with human pathogens, fairly... |

| A continuous high-resolution time-series survey of the hyperbenthic community and local environmental conditions was conducted in the benthic boundary layer (BBL) of the DYFAMED-BENTHOS station (43 degrees 24.61'N, 7 degrees 51.67'E at 2347 in depth in the NW Mediterranean) between January 1996 and April 1998 using bottom-moored sediment traps and a current meter. Sediment traps were set 4 m above the bottom. Hyperbenthos was collected as 'swimmers', i.e. those organisms that are alive when they enter the traps but are not part of the particle flux. Identification of these organisms showed that similar to 90%, were meiobenthic, Copepods dominated and comprised on average 75%, of total swimmers. They were followed by nauplii (12%), annelids (7.8%),... |

| Seasonal and spatial distributions of blowflies in relation to reproduction were investigated by baited traps in eight sites from lowland to high mountainous areas in Hokkaido, Japan. A total of 6,571 blowflies consisting of seven species in three genera was collected. The most predominant species was Calliphora vomitoria (Linnaeus) (5,946 flies, 90.5%), followed by C. nigribarbis Vollenhoven (537 flies, 8.2%). The remaining five species (Triceratopyga calliphoroides Rohdendorf, C. vicina Robineau-Desvoidy, C. loewi Enderlein, C. subalpina (Ringdahl), and Aldrichina grahami (Aldrich) were few in numbers. Calliphora vomitoria had the highest peak in autumn (October) in lowland to upland areas (70 m, 400 m, and 500 m), and it was also abundant from July to... |

| It is estimated that approximately 50% of the worlds population live on the coastal fringes of landmasses and the likely trend is for this number to increase to 75% within a decade. For centuries people have been drawn to coastal regions for the rich soils for agriculture (of deltas and lowlands), the extensive fisheries resources, transportation opportunities and recreation, and just for the natural beauty of living on beachfronts. However, the air-sea-land boundary referred to as the coastal zone is dangerous, comprised of an extremely dynamic, complex physical / biological set of environments. Worldwide, the coastal zone is characterized by high population densities, extremely varied and important biological diversity, including coastal fisheries, rich... |

| ABSTRACT: The soil mediated allelopathic effect of Echinochloa colona (L.) Link (jungle rice) was investigated on seed germination and seedling growth of Zea mays L. (maize). The experiment was conducted in the Agronomy farm of the University of Agriculture, Faisalabad, Pakistan. This study investigated the effect of different concentrations (1, 2, 3, 4 and 5% on w/w basis) of soil incorporated E. colona plant residues on emergence and seedling growth of maize and compared them with residue free soil (control). The results revealed the significant increase with soil incorporated E. colona residues in maize seedling growth till 2% E. colona plant residues, and an inhibitory effect was noticed over 2% E. colona plant residues in comparison to the control... |

| ABSTRACT: To investigate the allelopathic influence of soil incorporated plant residues of alligatorweed on emergence and seedling growth of maize (Zea mays), an experiment was conducted under laboratory conditions in the 2014-15 period. The effect of soil amended with whole plant residues of alligatorweed at different concentrations (1, 2, 3, 4 and 5% on w/w basis) was compared with residue free soil (control). Emergence traits, such as emergence percentage, time to 50% emergence, mean emergence time and emergence index were negatively influenced by weed residue incorporation as compared with weed residue free soil. Alligatorweed residues also exerted a pronounced negative influence on root and shoot lengths, root and shoot dry weights and seedling vigor... |
