25. CaracerÃsticas morfo-agronÃmicas e deterioraÃÃo controlada em sementes de tagetes / Morpho-agronomic characteristics and controlled deterioration in Tagetes seeds
The species of the genus Tagetes, commonly known by Marigold, present easy cultivation, are quite ornamental and show a relatively long flowering cycle. T. patula L. cultivars present a full blooming during the summer and can be traded either as cut flowers or as potted plants. On despite of its economic importance, little is known about their morpho-agronom

26. Yield and quality of peanut cultivars seeds affected by liming and haversting time. / Produção e qualidade de sementes de cultivares de amendoim (Arachis hypogaea L.) influenciadas pela calagem e pela época de colheita
The objective of liming is the neutralization of soil aluminum and manganese, as well as the supply of calcium, the increase of nutrient availability at the frut forming zone of in the soil and the increase of seed tegument thickness which may serve as a barrier to fungi penetration and water loss. In Experiment I, six peanuts cultivars yield components and

27. Mechanisms for suppressing NADPH oxidase in the vascular wall
Oxidative stress underlies many forms of vascular disease as well as tissue injury following ischemia and reperfusion. The major source of oxidative stress in the artery wall is an NADPH oxidase. This enzyme complex as expressed in vascular cells differs from that in phagocytic leucocytes both in biochemical structure and functions. The crucial flavin-contai

28. IdentificaÃÃo de cultivares de milho, feijÃo, algodÃo e soja por meio de enzimas e de proteÃnas resistentes ao calor / Identification of cultivar of corn, bean,cotton and soybean by using both enzymes and heat-resistent proteins
After the approval of the cultivars protection law and the new seed law there was an increase in cultivars identification using polymorphic markers. In this work both polymorphism and stability of isoenzymes and heat-resistant proteins in corn, bean, cotton, and soybean seeds with different levels of physiological quality were evaluated. Fiveâdays germinate

29. NÍVEIS DE HISTAMINA EM DIFERENTES MICROVINIFICAÇÕES / HISTAMINE LEVEL IN THE DIFFERENT MICROVINIFICATIONS
Histamine is an organic base that develops an important physiological and metabolic function in live organisms. It is formed in normal metabolic processes and through microorganisms enzymatic activity during the fermentation or deterioration. This substance may cause problems when ingested in large amounts, when the eliminating mechanism is inefficient or wh

30. Physiological potential evaluation of onion seeds and its relation to field plant performance. / Avaliação do potencial fisiológico de sementes de cebola e sua relação com o desempenho das plantas em campo.
Research has emphasized the relationship of laboratory germination and vigor to seedling emergence and stand establishment. In contrast, information relating seed vigor to plant performance is less available. This study was conducted to identify reliable procedures to rank onion ( Allium cepa L.) seed lots according to their physiological potential and to se

31. Métodos para avaliação do potencial fisiológico de sementes de melão. / Methods for the physiological potential evaluation in melon seeds.
This research was conducted to study and select procedures for the controlled deterioration, accelerate aging, electrical conductivity and potassium lixiviation tests, to verify their sensitivity to identify different vigor levels of melon (Cucumis melo L.) seed lots. Five seed lots each from the hybrids AF-646 and AF-682 were used. In the first experimental

32. Effects of heating and sulfuric acid on seed dormancy of Brachiaria dictyoneura cv. Llanero. / Comportamento da dormência de sementes de Brachiaria dictyoneura cv. Llanero submetidas às ações do calor e do ácido sulfúrico.
Seed dormancy is emphasized in the literature as a problem for the establishment of tropical pasture grasses. Immersion of seeds in sulfuric acid (H2SO4) has been widely used and is effective in breaking dormancy of Brachiaria seeds, although this treatment raises inconveniences relating to the operator safety during application. Moreover, refusal of residue

33. Influencia da utilização do mobiliario adaptado na postura sentada de individuos com paralisia cerebral espastica
The present study had as objective to evaluate the sitting posture of children with spastic cerebral palsy, searching the existence of differences in that posture. The children make use of he furniture that furnished support for superior and inferior members. First it was drawn and manufactured the necessary furniture to accomplish the research. After that,

35. Characterization of green seed, an Enhancer of abi3-1 in Arabidopsis That Affects Seed Longevity1
Seeds are usually stored in physiological conditions in which they gradually lose their viability and vigor depending on storage conditions, storage time, and genotype. Very little is known about the underlying genetics of seed storability and seed deterioration. We analyzed a mutant in Arabidopsis disturbed in seed storability. This mutant was isolated

36. Microbial Studies on Shelf Life of Cabbage and Coleslaw
The microbiology of a common commercial type of coleslaw was investigated with the objective of extending its shelf life at refrigerator temperature by delaying microbiological spoilage. Cabbage, its principal ingredient, had a total bacterial count of about 105/g. Microbial growth in cabbage was prevented by storage at 1 C but not at 10 C or above. In coles
