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®... |

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... |

Adult emergence and mating behavior of Neoleucinodes elegantalis Guenée were studied under laboratory conditions (23 ± 1°C, 12 h photophase and 70% RH). Adult emergence occurred only at scotophase period. Female began to emerge from the 1st hour to 8th hour with a peak occurring at 4th hour of scotophase. Male showed similar trend, but emerging from 2nd to 11th with a peak also at 4th hour of scotophase. Mating was preceded by wing vibration in the male prior to and during walking approach. Mating occurred only during the scotophase period between the 4th and 10th hour of scotophase, with the peak occurring at the 7th hour. Newly emerged N. elegantalis couples rarely mated (2.8%) whereas 48 and 96 h old couples mated 26.3% and 27.5% respectively. Glands... |

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... |

ABSTRACT In central Chile, Rhagoletis brncici and R. conversa, can be found in sympatry, associated with the fruit of their native host plants: Solanum tomatillo and S. nigrum (Solanaceae), respectively. Third-stage larvae must emerge from its host in search of pupation sites, and during this period larvae must find an appropriate pupation microhabitat while avoiding predation and adverse abiotic factors. In this study, we explored whether these sympatric species differ in terms of the timing of their larval exit from the host fruit in search of pupation sites. Field-collected fruits from host plants were checked daily for larval emergence, within 24 h, under laboratory conditions, in order to determine the time of the event. We found that these species... |

ABSTRACT: This study evaluated the efficiency of methods to overcome seed dormancy in different storage periods in the production of pecan seedlings. Seeds were submitted to the following treatments: T1, T4 and T7 - control treatments (seeds with no treatment, stored at room temperature for 30, 60 and 90 days, respectively), T2, T5 and T8 - stratification (seeds were distributed in boxes with wet sand maintained at a temperature of 4°C for 30, 60 and 90 days, respectively), T3, T6 and T9 - scarification + stratification (seeds scarified with sandpaper n.80 and stratified by 30, 60 and 90 days, respectively), in completely random experimental design. Plant height, stem diameter, number of leaves, full emergence and emergence speed index (ESI) were evaluated... |

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%),... |

The tillage and residue management during soil bed preparation need to be in appropriate manner for sustainable farming practice. The effects of tillage and residue management methods on corn cropping were studied on loamy soil in Bangrakum district, Phitsanulok Province, Thailand. The effects of five commonly used tillage methods: subsoiler tillage (ST), three methods of conventional tillage (CT1, CT2 and CT3), no-tillage (NT), as main factors and two corn residue management methods; burned (R1) and unburned (R2), as sub-factors were studied in a randomized strip plot configuration. Tillage treatment showed significant effect on physical and chemical soil properties, plant growth and development, grain yield, total aboveground biomass and most... |

In most northwest provinces of Iran such as West Azarbaijan province, soil salinity is a growing problem, particularly in irrigated agricultural areas, and has been found to reduce barley yield, dramatically. To investigate the effect of sodium chloride on two barley (Hordeum vulgare) cultivars, four levels of salinity: 0, 4, 8 and 12 dS/m, were employed as a factorial experiment arranged in a completely randomized design with three replications in a controlled environment of the greenhouse during 2017-2018. The results indicated that increasing salinity from 0 to 12 dS/m, decreased the emergence percentage significantly. Two cultivars of Zarjoo and Valfajr responded differently to salinity, so that Zarjoo showed a significantly higher emergence rate. This... |

ABSTRACT The objective of this study was to evaluate the performance of three rice cultivars under saline water irrigation. The experiment was carried out in full sun at the Experimental Farm of the Unilab, in Redenção, Ceará, Brazil, in January 2016. The experimental design was completely randomized (CRD), in a 5 x 3 factorial scheme [irrigation water electrical conductivity (ECw: 0.5, 1.0, 2.0, 3.0 and 4.0 dS m-1) versus three rice cultivars (C1 - Ligeirinho, C2 - Casado and C3 - Meruinho)], totaling 15 treatments, with 4 replicates of 30 seeds per cultivar. After 21 days, the following variables were evaluated: emergence percentage (EP), emergence speed index (ESI), mean time of emergence (MTE), mean speed of emergence (MSE), shoot dry matter (SDM),... |
