13. Bioactivity and potential therapeutic benefits of some medicinal plants from the Caatinga (semi-arid) vegetation of Northeast Brazil: a review of the literature
Medicinal plants have been used in traditional medicine for several thousand years all over the world. In this sense, information from Brazilian ethnic groups on folk medicine have contributed to the discovery of pharmacological activities from various plant-derived agents potentially leading to the innovative drugs. The Caatinga (semi-arid) vegetation is a

14. Phosphorus analysis in soil under herbaceous perennial leguminous cover by nuclear magnetic spectroscopy.
The availability and the reserves of organic phosphorus are controlled by its mineralization rate and are also influenced by changes in soil management. The objective of this study was to evaluate the influence of soil covering with different leguminous plant on soil organic P by 31P-NMR spectroscopy. Alkaline soil extracts were obtained from two depths (0-5

15. Colonization of Brasilonema octagenarum UFV-E1 (Cyanobacteria) in young plants of eucalyptus and the identification of bioactive substances / Colonização de Brasilonema octagenarum UFV-E1 (Cyanobacteria) sobre plantas jovens de eucalipto e a identificação de substâncias bioativas
Cyanobacteria produces a wide variety of biological compounds of economic-industrial interest, often referred to as "bioactive molecules". This is a broad term that include substances, which at low concentrations, are able to affect vital metabolic processes. Recently, a new species of cyanobacteria, Brasilonema octagenarum UFV-E1, was identified. The cyanob

16. A new approach for obtaining rapid uniformity in rice (Oryza sativa L.) via a 3x x 2x cross
A triploid (2n = 3x = 36) rice plant was obtained by screening a twin seedling population in which each seed germinated to two or three sprouts that were then crossed with diploid plants. One diploid plant was chosen among the various F1 progenies and developed into an F2 population via self-pollination. Compared with the control variety Shanyou 63, this F2

17. Componentes do balanço de água em um Cambissolo cultivado com meloeiro irrigado por gotejamento, com e sem cobertura da superfície / Water balance components in an Inceptsol cropped with muskmelon drip irrigated, with and without covered surface
The knowledge about the soil water balance is essential to soil-water-plant system management. Thus, this research aimed to study the water balance components in an Inceptsol cropped with muskmelon under drip irrigation, with and without surface covering, in the county of Baraúna, Rio Grande do Norte State, Brazil (05º0448 S, 37º3700 W). In an experimenta

18. Plantas de cobertura e doses de torta de mamona no cultivo orgÃnico de alface sob plantio direto / Covering plants and castor cake doses in no-tillage organic production of lettuce
No-tillage system and organic agriculture has been bringing benefits to environment, agriculturist and consumer. However, there are still little information about the most adequate practices to no-tillage system, specially about vegetables production, and organic. The use of industrial residues is an interesting practice by the environmental and economic poi

19. Nitrogen transformations in soil-plant system after herbicide application / Transformações do nitrogênio no sistema solo-planta após aplicação de herbicidas
Herbicide adoption might modify nitrogen dynamics in agroecossystems and, for consequence, nutrient availability for plants and microorganisms. These modifications may occur because of plant physiologic changes and/or due to herbicide effects on activity and composition of soil microbial community, which has important functions on system N modifications. In

20. Construction of cowpea genetic map using ISSR, DAF e CAPS markers / ConstruÃÃo de um mapa genÃtico para feijÃo-caupi com marcadores moleculares ISSR, DAF E CAPS
Cowpea crop is of great economical importance in Brazil being the Northeastern region the main producer. The low levels of resistance to pathogens is one of the restricting factors for the Brazilian competitiveness worldwide. One of the most important disease is caused by Cowpea severe mosaic virus - CPSMV. The control of CPSMV can be achieved whit the use o

21. Análises biométricas e mapeamento de QTLS para tolerância à seca em milho / Biometric analysis and mapping of QTLS for drought tolerance in maize
One of the major goals of crop improvement is the increase in agricultural productivity associated with the improvement for the consumption in human or animal feeding. These goals can be achieved through improvements in environmental conditions or by improving the genetic potential of populations. Recently, much has been discussed about global warming, clima

22. Intercrops of soil covering plants species for green manurig prior corn and cabbage under organic management / Consórcios de espécies de cobertura de solo para adubação verde antecedendo ao cultivo de milho e repolho sob manejo orgânico
Avaliaram-se, no Estado do Rio de Janeiro, quatro espécies botânicas, consorciadas ou não, para adubação verde e cobertura do solo, antecedendo as culturas de milho verde e repolho. Estas culturas foram implantadas em sistema plantio direto e submetidas ao manejo orgânico. O estudo com o milho verde foi conduzido na Baixada Fluminense (Seropédica) a 3

23. Development of an electronic device for attraction drops of the electrostatic spraying in citric plants / Desenvolvimento de sistema eletrônico para pulverização e atração de gotas em plantas cítricas
The technology of application of agricultural defensives in tree like plants and orchard plants in general way, still little is researched in Brazil. Ahead of requirements of the international market, the application technology must take care of some parameters that will give the credibility of the Brazilian products in the exterior market, as for the certif

24. Espaçamentos entre plantas e cobertura do solo com cama-de-frango na produção da bardana (Arctium lappa L) / Planting spaces and poultry litter soil cover in the yield of bardana (Arctium lappa L)
The experiment was carried out in the medicinal garden of the Universidade Federal da Grande Dourados UFGD, in the period from February to October 2006. The survey aimed to study the growth, development and yield of Bardana responding to five different spacing rows between the plants (40,0; 47,5; 55,0; 62,5 and 70,0 cm) and to the use - CCF (10 t ha-1) or no
