13. Sucrose metabolism during fruit development in coffea racemosa.
Sucrose is one of the compounds in the raw coffee bean that has been identified as an important precursor of coffee flavour and aroma. In order to increase our knowledge of sucrose metabolism in coffee species, sucrose and reducing sugar content were investigated in the fast fruit-ripening coffee species Coffea racemosa. Fruits were harvested regularly from

14. Criopreservação e produção de sementes sintéticas in vitro de mangabeira / Cryopreservation and in vitro synthetic seed production of mangabeira
The mangabeira is a medicinal and fruit species of the Brazilian Cerrado that presents propagation difficulties through seeds, due, mainly to the low germination rate and recalcitrance. Furthermore, it undergoes an accelerated genetic erosion process as a consequence of the extractivist exploitation. As a result, the development of alternative methodologies

15. Evaluation of phenotypic traits of cariogenicity of Strptococcus Mutans genotypes isolated from dental biofilm / Avaliação de caracteristicas fenotipicas de cariogenicidade de genotipos de Strptococcus Mutans isolados de biofilme dental
Mutans streptococci, mainly Streptococcus mutans, are considered as the main microorganisms related to dental caries. These microorganisms are present in oral cavity as distinct genotypes, which may show distinct phenotypic traits. In this context, it was evaluated the S. mutans genotypic diversity in dental biofilm formed in vivo and in situ during 3 days u

16. Estudo do crescimento de Ceriporiopsis subvermispora em culturas submersas para a produção de inóculos destinados ao processo de biopolpação / Studies on the submerged culturing of Ceriporiopsis subvermispora for inocolum production used in biopulping processes
The present work evaluated suitable systems for producing Ceriporiopsis subvermispora mycelium in submerged cultures. Mycellium produced was used in subsequent inoculation of wood chips in biopulping processes. The development of appropriated technologies for producing large amounts of inoculum may be a key step in biopulping, since currently there are no es

17. Cryopreservation of the sugarcane germplasm / Criopreservação de germoplasma de cana-de-açúcar
This study was carried out to develop some protocols for cryopreservation of sugarcane germplasm in liquid nitrogen at -196C. The exposure time of the shoot tips encapsulated in the laminar flow chamber for obtaining the moisture contents of 30, 20 and 10% was determined in an assay. The results were analyzed and interpreted, by using the free R software. Th

18. Processing and characterization of biocomposites of PHB with acetylated and no-acetylate natural fibres of coconut and sisal / Processamento e caracterização de biocompositos de PHB com fibras naturais de coco e sisal acetiladas e não-acetiladas
The problem of urban waste accumulation has increased in recent decades and the large consumption of plastics is one of those responsible for this situation. These materiaIs have the ability to remain in the environment for many years making it difficult further to provide its correct destination. This problem was the main motivation of the work presented he

19. Matéria orgânica de Latossolos Húmicos: análises térmica e espectroscópica, efeito do uso e correção química / Organic matter of humic Latosol (Oxisol): thermal and spectroscopic analyses, land use and chemical correction
The objective of this study was to contribute to the clarification of several aspects related to the behavior of organic matter (OM) in highly weathered tropical soils. Six samples of humic A horizon Latosol were collected from three sites in Minas Gerais: i) Sericita, (under coffee crop, pasture, ferns and Atlantic Forest fragment); ii) Mutum (under Atlanti

20. Acúmulo de biomassa, de nutrientes e de sacarose por duas variedades de cana-de-açúcar, influenciados por doses de fósforo / Accumulation of biomass, from nutrients and sucrose of two sugarcane varieties in function of phosphorous doses.
No Brasil, a cana-de-açúcar é normalmente utilizada para a produção de açúcar, álcool e alimentação animal. Na maioria dos solos brasileiros, o teor de fósforo não assegura crescimento satisfatório da cultura, havendo, portanto, necessidade de fornecê-lo na adubação. O fósforo é um elemento importante na nutrição e no metabolismo da cana

21. Desenvolvimento de raízes e produtividade de cana-de-açúcar relacionados à adubação nitrogenada / Root growth and sugarcane productivity related to nitrogen fertilization
Studies of nitrogen fertilization in sugarcane are usually restricted to evaluations of the effects on growth and productivity of the shoots. There are evidences that nitrogen fertilization favors the growth of roots, the absorption of nutrients and sugarcane productivity. This work was designed to evaluate root development and sugarcane productivity (SP81 3

22. Expressão de genes de resposta a estresses ambientais em mutantes defectivos de milho e Arabidopsis
Reverse genetics and gene expression analysis has been the main approach adopted in order to carry out the functional characterization of genes. Results from such studies have typically demonstrated that same gene can be involved in different cell functions. In this context, analysis of trehalose metabolism in plants has revealed that this pathway plays an i

23. Análise de crescimento e produtividade de duas variedades de cana-de-açúcar (Saccharum spp) influenciadas por doses de fósforo
The knowledge of the leaf area is required every time the sugarcane is subjected to evaluation in which different varieties are compared or submitted to different environmental conditions, managements or fertilizations, therefore evidently showing alteration in dimensions of the plant leaves, so affecting the photosynthetic process. Although the higher breat

24. Avaliação de dois cimentos de ionômero de vidro comparados a um selante resinoso, utilizados para selamento de fossas e fisuras aplicados em esmalte bovino hígido, sob condições de severo desafio cariogênico: estudo in situ / Evaluation of two glass ionomer cements compared to a resin sealant, employed for pit and fissure sealing on intact bovine enamel, under severe cariogenic challenge - in situ study
This in situ study, developed in a 14-day period, aimed to evaluate the effect of two glass ionomer cements (GIC) compared to a resin sealant, employed for pit and fissure sealing on intact bovine enamel, with accumulation of dental biofilm, by analysis of the fluoride content on the dental biofilm and longitudinal microhardness. Eighty-eight enamel blocks (
