13. Obtenção de extrato de matriz oleaginosa de origem amazonica via tecnologia supercritica : determinação das isotermas de rendimento global, dos parametros de processo e caracterização quimica dos extratos / Obtaining of extract from amazon oil matrix via supercritical technology : determination of the global yield isotherms, kinetic parameters and chemical characterization of the extracts
O Brasil constitui um grande produtor de plantas e frutas tropicais, cujo emprego pelas indústrias farmacêutica, alimentícia e de cosméticos vem aumentando a cada ano. Com a finalidade de aproveitar efetivamente o seu potencial, o país necessita desenvolver e/ou adaptar tecnologias que sejam economicamente viáveis e ecologicamente corretas como, por ex

14. RegeneraÃÃo "in vitro", estudos histolÃgicos e transformaÃÃo genÃtica da momoneira (Ricinus communis) / "In vitro" regeneration, histologycal studies and genetic transformation of castor-bean (Ricinus communis)
Castor bean (Ricinus communis) is an oilseed crop with considerable economic value because of the composition of its oil seed. However, there are some constraints in your use for human and animal food because of the presence of toxic and allergenic proteins. This problem could be solved or reduced through genetic engineering. However, this crop is recalcitra

15. Uso de resíduo orgânico da produção de biodiesel direta da semente na atenuação dos efeitos de hidrocarbonetos de petróleo no solo. / Use of organic residue from the biodiesel production directly from the seed in the reduction of petroleum hydrocarbons effect in soil.
In the search for energy resources that can minimize the environmental impact in the transportation, refining and distribution of fossil fuels, biodiesel is highlighted as an economically viable alternative and totally renewable if compared to petroleum. With the regulations of Law 11097, from 2005, Brazil became widely known as one of the planet largest pro

16. Potencial de coprodutos do biodiesel para alimentaÃÃo de ruminantes / Potential of biodiesel co-products for ruminant feeding
Brazil, due to its climatic diversity and of ecosystems allows a range of possibilities of oilseed plants for biodiesel production. New co-products are being generated, bringing the need to study the viability of use of those alternative feeding sources. The experiment was conducted in the Animal Research Laboratory of the Federal University of Lavras (UFLA)

17. Extração supercritica de matrizes vegetais oleaginosas : rendimento global, cinetica de extração, composição quimica e atividade antioxidante / Supercritical extraction from oilseed plants : global yield, extraction kinetics, chemical composition and antioxidant activity
Extratos brutos e princípios ativos extraídos de plantas nativas brasileiras possuem características altamente atrativas por serem capazes de prover, além da nutrição básica, benefícios à saúde ou medicinais como a prevenção e/ou tratamento de doenças. A extração com fluido supercrítico (SFE) caracteriza-se pela obtenção de extratos de elev

18. Ferrugem asiática da soja: métodos de preservação dos urediniósporos e fatores relacionados à infecção do hospedeiro / Asian soybean rust: methods for uredospores preservation and factors related to host infection
Soybean is the agricultural crop with the largest planted area in Brazil. The country stands out in the world scenario as the second-largest producer and exporter of this oilseed crop. The Asian rust (AR), caused by the fungus Phakopsora pachyrhizi, is one of the most serious phytosanitary problems of soybean in Brazil, especially because no cultivars exist

19. Partitioning genetic effects due to embryo, cytoplasm and maternal parent for oil content in oilseed rape (Brassica napus L.)
Analysis of genetic main effects and genotype x environment (GE) interaction effects on the oil content of oilseed rape (Brassica napus L.) was conducted by using a genetic model for the quantitative traits of seeds in diploid plants. The experiments were carried out over two years with 8 parents and a diallel mating design, which produced F1 and F2 generati

20. Antioxidant activity of extracts of freeze-dried Brazilian plants / Atividade antioxidante de extratos liofilizados de plantas brasileiras
Antioxidant aetivity of liophilized extraets of Brasilian plants, The antioxidante aetivities of 140 lyophilized extraets of different parts of 4S Brasilian plants were evaluated in amodel aqueous system eontaining B-earotene and linolei aeid. The exttaets that presented a marked proteetive effeet were subsequen-.tly tested in a lipid system (soybean oil). D

21. Photorespiratory NH4+ Production in Leaves of Wild-Type and Glutamine Synthetase 2 Antisense Oilseed Rape1
Exposure of oilseed rape (Brassica napus) plants to increasing leaf temperatures between 15°C and 25°C increased photorespiratory NH4+ production from 0.7 to 3.5 μmol m−2 s−1. Despite the 5-fold increase in the rate of NH4+ production, the NH4+ concentration in root and leaf tissue water and xylem sap dropped significantly, whereas that in the leaf ap

22. An Antibody to the Castor Bean Glyoxysomal Lipase (62 kD) also Binds to a 62 kD Protein in Extracts from Many Young Oilseed Plants 1
An antibody raised against purified glyoxysomal lipase (triacylglycerol hydrolase EC 3.1.1.3.) from castor bean (relative molecular weight of 62,000) also binds to a protein with a relative molecular weight of 62,000 in extracts of food reserve tissues from many young oilseed plants. These plants include Brassica napus L., Zea mays L., Arachis hypogaea L., G

23. Oilseed rape and seasonal symptoms: epidemiological and environmental studies.
BACKGROUND--There is widespread concern that the cultivation of oilseed rape leads to seasonal epidemics of respiratory symptoms in populations living in the neighbourhood, and it has been suggested that the plant is a potent allergen. A study was therefore undertaken to determine the prevalence of seasonal symptoms in rural populations close to and far from

24. Characterization of Stomatal Closure Caused by Ultraviolet-B Radiation1
The effects of ultraviolet-B (UV-B) radiation on stomatal conductance (gs) in pea (Pisum sativum L.), commelina (Commelina communis L.), and oilseed rape (Brassica napus L.) plants were investigated. Plants were grown in a greenhouse either with three different high ratios of UV-B to photosynthetically active radiation or with no UV-B radiation. Pea plants g
