13. Deterioração controlada de sementes de tres hibridos interespecificos de capim elefante x milheto / Controlled deterioration of seeds of three interespecific hybrids of elephant grass x pearl millet
The interespecific hybrid Pennisetum purpureum (elephant grass) x P. glaucum (pearl millet) has been developed aiming to get the rusticity and high forage production of elephant grass and the high production of pure seeds of pearl millet. However, it revealed low phenotypic uniformity (around 50.0%) as well as low pure seed production (5 -10.0%). A recurrent

14. Avaliação do potencial fisiológico e métodos de condicionamento, secagem e armazenamento de sementes de pepino / Evaluation of the physiological potential and priming, drying and storage of cucumber seeds
The objectives of this research were to identify reliable methods to evaluate the physiological potential of cucumber seeds, verify the relationship between seed physiological potential and field performance, as well as to define a suitable procedures for seed priming, drying and storage. The study was conducted in two experimental phases using seed lots of

15. 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

17. Conservation of Euterpe oleracea seeds / Conservação de sementes de açaí (Euterpe oleracea Mart.)
Seeds of Euterpe oleracea Mart. are considered recalcitrant and demand enlargement of the knowledge about the factors that interfere in its conservation. The present work aimed to verify the effects on seed moisture content and of the atmosphere temperature in the maintenance of seed quality. Seeds of cultivar BRS Pará, with moisture content of 43,4%, 37,4%

18. Viability equation constants for two Phaseolus vulgaris cultivars / Constantes de viabilidade para sementes de feijoeiro dos cultivares Tibatã e Una
The previous knowledge of seed performance during storage is important to evaluate its storability. This experiment analysed Phaseolus vulgaris seed storage aiming to get viability equation constants for two cultivars, as to guarantee seed disposal and conservation. Seeds were rehydrated over water or dried over silica gel, both at 25ºC, from the initial mo

19. Avaliação do comprometimento endócrino do pâncreas em crianças e adolescentes portadores de fibrose cística / Evaluation of the endocrine pancreatic dysfunction in children and adolescents with cystic fibrosis
INTRODUCTION: Cystic fibrosis-related diabetes is a common complication leading to clinical deterioration of these patients. Aiming at an earlier diagnosis, we investigated the kinetics of the glucose-metabolism abnormalities by evaluating glucose, insulin, pro-insulin, C-peptide and glucagon responses after oral glucose (OGTT) and a mixed meal tolerance (MM

20. 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

21. Estudo da aplicação de energia de microondas na secagem da noz macadamia (Macadamia integrifolia Maiden &Betche). / Study of the application of energy of microwaves in the drying of the nuts macadamia (Macadamia integrifolia Maiden &Betche).
The macadamia tree (Macadamia integrifolia Maiden &Betche) produces a nut of high commercial value, distinguishable from other nuts by the delicate taste and outstanding quality of its oil. The most critical stage of macadamia nut processing is the drying of the kernels, as a minimum quality standard can only be achieved under specific controlled conditions.

24. 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
