| The aim of this study was to evaluate the effect on the physiological performance of maize seeds (Zea mays L.) of micro-priming with Bacillus subtilis associated with techniques of water restriction and seed-coating. The micro-priming of the seeds, without any additional techniques, was carried out using a commercial product, Rhizoliptus ® (Bacillus subtilis). Water restriction was carried out using a PDA medium (Potato - Dextrose - Agar) with mannitol (-0.7 MPa), upon which the culture was grown for 48hours. One hundred sterilized corn seeds were placed in each dish. Once root protrusion occurred in one seed, the rest were removed and kept in a laboratory environment for 48 hours. The coating was carried out by the addition of Seed Polymer Color HE (50 ml... |

| ABSTRACT Occurrence of Fusarium spp. is one of the problems, most limiting to growth of seedlings, in nurseries. This pathogen can be transmitted via seeds and causes damages to the seedlings during pre- and post-emergence stages. The present study aimed to identify Fusarium spp. at the species level based on morphological and molecular characteristics and to verify the pathogenicity of these isolates in seeds lots of Pinus elliottii and P. taeda. For this, we used two Fusarium isolates and five lots of Pinus spp. seeds. Morphological characterization was performed based on a key, specific to Fusarium spp. identification, whereas, molecular identification was carried out by amplification and sequencing of the regions from internal transcribed spacer (ITS)... |

| Este trabalho teve por objetivo isolar, identificar e selecionar isolado(s) de Fusarium spp. em sementes de pepino e verificar a sua influência na qualidade fisiológica. Foram utilizados três sublotes e os tratamentos consistiram em: testemunha absoluta; BDA + manitol - 0,8Mpa; BDA; BDA + manitol - 0,8Mpa + fungo; e BDA + fungo. A qualidade fisiológica foi avaliada através de testes em laboratório e casa de vegetação. Cinco isolados de Fusarium verticillioides foram identificados e a sua transmissão através das sementes para plantas não foi possível afirmar. A técnica da restrição hídrica foi eficiente para proporcionar infecção das sementes, sabendo que e o fungo influencia negativamente na qualidade fisiológica das sementes de pepino da cultivar Caipira. |
