1. Waterlogging-induced changes in fermentative metabolism in roots and nodules of soybean genotypes
Waterlogging blocks the oxygen supply to the root system which inhibits respiration, and greatly reduces the energy status of cells that affect important metabolic processes. This study evaluated fermentative metabolism and carbohydrate contents in the root system of two soybean (Glycine max L. Merril) genotypes under hypoxic and post-hypoxic conditions. Nod

2. Composição química dos grãos e da cera foliar de variedade Glycine max (L.) Merrill cv. MG/ BR-46 Conquista cultivada sob atmosfera enriquecida de gás carbônico e temperatura elevada
The concentration of carbon dioxide (CO2) has increased in the last decades, due mainly to the combustion of fossil fuels. A gradual increase of the global temperature is expected as a consequence. Soybean is an important crop in most countries, being consumed either as human or domestic animals food. The present work is composed of two chapters, the first d

3. Limites e possibilidades do balanço social
In the process of dissemination of social and environmental practices, companies have realized that sugarcane social responsibility initiatives can be used to reduce costs, increase competitive advantage, manage risk and reputation and turned the green initiatives on business strategies. Thus, sugarcane industry use monitoring mechanisms and accountability s

4. Proposta de um modelo de planejamento agregado da produção numa usina de açúcar e álcool vinculado à flutuação de preços em mercados à vista e no mercado futuro. / A model of aggregate production planning in a sugar mill and alcohol linked the decisions of prices in future markets and present markets.
The objective of study this dissertation is to develop a model of aggregate production planning to support the decisions of management and board level of sugar and alcohol plants in regard to varieties of cane harvested each week, purchasing cane of nonsugar, the type of transport (own or outsourced) to use each week, the total cane processed per week for ta

6. Responsabilidade social e abertura de capitais : uma descrição dentro do complexo agroindustrial canavieiro do Brasil
The companies of the sugar-alcohol sector kept the same characteristics since their beginning up to the nineties. They were controlled by oligarchic groups, were under the State protection and were not worried about dissociating from the negative stigma of exploiting the workforce and destroying the environment. In the beginning of the XXI century, the secto

7. Genetic transformation of sugarcane by biolistic and Agrobacterium tumefaciens to study the mechanism of programmed cell death / Transformação genética de cana-de-açúcar por biolística e Agrobacterium tumefaciens visando estudar o mecanismo de morte celular programada
Sugarcane is one of the main crops planted in Brazil and presents significant socioeconomic and agribusiness importance to the country. The world scene is quite favorable as regards the marketing of its two main products, sugar and alcohol, driving the development of the national sugar-alcohol sector. Therefore, the sugarcane genetic breeding appears as the

8. Institutional arrangements in Brazilian agriculture: a study on the use of contracts in South Central Brazil´s sugar-and-alcohol industry / Arranjos institucionais na agricultura brasileira: um estudo sobre o uso de contratos no sistema agroindustrial sucroalcooleiro da região centro-sul
This work analyzes the institutional framework that mediates market transactions between suppliers (plants) and processing firms (distilleries) within South Central Brazils sugar and alcohol agroindustry. To that end, a comparison is made between institutional production arrangements in traditional and non-traditional sugar cane farming regions. The theoreti

9. Desempenho competitivo do estado de São Paulo e da região sul do estado de Goiás na produção de cana-de-açucar
The sugar cane is an important activity which generates energy and with high capacity to link many sectors of its economy. After a plenty of prohibitions and challenges faced by the sector in the two last decades, such as the Pro-alcohol project, the success of the car with alcohol engine, the beginning of the exportation of sugar for the private sector, the

10. Dinâmica de nutrientes na cana-de-açúcar em sistema irrigado de produção
One of the main investments in the alcohol and sugar sector is the technological innovations searching for increments in the productivity of the sugar cane fields, as an example, the genetic improvement of the sugar cane producing new varieties more productive and environmentally adapted. The productive capacity of these varieties, however, may have being un

11. Avaliação de coeficientes de rendimento e modelagem do processo fermentativo de produção de etanol
The yield ethanol (hP) is one of the most important parameters to be evaluated in the industrial process of alcohol fermentation. Because most plants neither present a reasonable level of automation, nor perform frequent analytical measures during the batch, the hP is currently calculated by methodology based on by-products formed in the process. Such calcul

The object of this work was to evaluate the efficiency of the application of silt from the sewers as a source of nitrogen (N) and vinhaça* as a potassium source (K) in the sugar-cane crop and compare it with the efficiency of the use of potassium and nitrogen from mineral sources to the cane yield and technological characteristics. Besides that it was also
