14. Nematóides associados ao girassol em áreas de cerrado do Distrito Federal.
RESUMO: Efetuou-se um levantamento com o objetivo de determinar a ocorrência de nematóides em 18 genótipos de girassol (Helianthus annuus L.). cultivados, na época chuvosa, na área experimental da Embrapa Cerrados, Planaltina, DF em maio de 1993. Três amostras compostas de solo e raízes foram coletadas da rizosfera de cada genótipo antes da colheita.

15. Características químicas e digestibilidade in vitro de silagens de girassol.
Silages of 13 cultivars (AS243, AS603, Cargill 11, Contiflor 3, Contiflor 7, DK180, M734, M737, M738, M742, Rumbosol 90, Rumbosol 91, V2000 and Media) of sunflower (Helianthus annuus L.) were evaluated for chemical characteristics and in vitro dry matter digestibility (IVDMD). The silages were produced when the plants had >90% ripe grains. The experimental p

16. Interações e viabilidade do plantio consorciado de pinhãomanso (Jatropha curcas) e girassol (Helianthus annuus L.) / Feasibility and interactions of intercropping planting of physic nut (Jatropha curcas l.) and sunflower (Helianthus annuus l.)
With the recent advent of biodiesel in Brazil, there has been a significant increase in the number of research on the potential of utilizing oleaginous as raw material, especially in physic nut (Jatropha curcas L.), due to its superior oil technical characteristics, as well as the plants hardiness and productivity. However, since the production of physic nut

17. Mechanical expelling of peanut and sunflower oils to biodiesel production by basic catalyst / Extração mecanica de oleos de amendoim e de girassol para produção de biodiesel via catalise basica
Biodiesel is a fuel produced from triglycerides found in nature, like vegetable oils and animal fats. It has occupied an important position in Brazil, especially after the creation of a law that authorizes its mixture in diesel. All the focus gave to this new fuel demands a complete study of all productive chain, that comprehend from agriculture sector, by r

18. Avaliação do desenvolvimento de girassol por meio de analise de proteinas e metaloproteinas / Evaluation of sunflower development based on protein metalloprotein analysis
This work describes an evaluation of sunflower (Helianthus annuus L.) growth when it is submitted to seven treatments, and their interrelation with proteins and metalloproteins analyses. Metal ion solutions (Cd, Cu, Pb and Zn) were added to the substrate in four treatments. In another two, used as controls, the plants were irrigated only with deionized water

21. Dark Stomatal Movement in Sunflowers in Response to Illumination under Nitrogen
Experiments were performed on intact sunflowers (Helianthus annuus) placed in a specially designed experimental chamber which allows instantaneous modifications of the atmospheric composition without changing any other conditions. After one night in normal conditions, the plant was illuminated under pure nitrogen atmosphere; the opening stomatal movement, me

22. Host range encoded by the Agrobacterium tumefaciens tumor-inducing plasmid pTiAg63 can be expanded by modification of its T-DNA oncogene complement.
Agrobacterium tumefaciens harboring pTiA6 incite unorganized tumors on Nicotiana rustica, sunflowers, carrots, and tomatoes, whereas isogenic strains of agrobacteria harboring pTiAg63 form "rooty" tumors on N. rustica and are essentially avirulent on sunflowers, carrots, and tomatoes. In this report we show that the different host range characteristics of th

23. Water Potential and Stomatal Resistance of Sunflower and Soybean Subjected to Water Stress during Various Growth Stages 1
Plants of two varieties of soybean (Glycine max (L.) Merr.) and two varieties of sunflower (Helianthus annuus L.) were grown in controlled environments and subjected to water stress at various stages of growth. Leaf resistances and leaf water potentials were measured as stress developed. In soybeans the upper leaf surface had a higher resistance than the low

24. Rhizosphere Soil Aggregation and Plant Growth Promotion of Sunflowers by an Exopolysaccharide-Producing Rhizobium sp. Strain Isolated from Sunflower Roots
Root-adhering soil (RAS) forms the immediate environment where plants take up water and nutrients for their growth. We report the effect of an exopolysaccharide (EPS)-producing rhizobacterium (strain YAS34) on the physical properties of sunflower (Helianthus annuus L.) RAS, associated with plant growth promotion, under both water stress and normal water supp
