Coutinho, GivagoFundação de Amparo a Pesquisa do Estado de Minas Gerais; CHAPTER I: Aiming to evaluate factors for application in the development of high quality rootstock, two experiments were conducted in protected environment (glasshouse). Factors such as either the presence or absence of the endocarp on the seed, sources of substrate and different concentrations of poultry litter present in the substrate were evaluated as ...
Qualidade hospedeira e temperatura na biologia de Diaeretiella rapae (McIntosh,...
Souza, Monique Ferreira deFundação de Amparo a Pesquisa do Estado de Minas Gerais; Survival, development time, fertility, behavior, longevity, and other biological features of Diaeretiella rapae (McIntosh) are conditioned by temperature and host. However, studies of host quality changes due to its temperature adaptability have not been performed yet. Therefore, this study evaluated the adaptability of Lipaphis pseudobrassicae (Davis) an...
Validação de métodos para teste de germinação de sementes de espécies florestai...
Soares, Dayene Cássia de PaulaBrazilian sawn wood exports of tropical species between 2006 and 2011 was over 1.4 billion kilograms and generated a profit of more than US$1.08 billion. Researchers are concerned over regulation of forest tree seed trade. Therefore, were conducted a research to verify seed quality through secure and robust analysis methods aimed at evaluating normal and abnormal seedling sand dead seeds from the validation pro...
Desempenho e divergência genética de genótipos de tomate para processamento ind...
Bittar, Cecília AlvesThe growth of processing tomato market makes national and multinational seed companies interested to develop new hybrids for this segment. Thus, it becomes necessary to analyze, in Brazilian field conditions, the main agronomic characters and performance of new hybrids. This study evaluated the performance and genetic divergence of tomato genotypes for fruit firmness, fruit set concentration, index of peduncle ...

Implicações da inoculação com Azospirillum brasilense e de níveis de N em milho...
Queiroz, Isabel Dayane de SousaMaize is one of the cereals with greatest economical and nutritional importance. Its production is directly related to adequate supply of nutrients, especially nitrogen, which can be added by fertilization, or by its biological fixation. One of the most important nitrogen fixing microorganisms in grasses is Azospirillum sp., which, besides supplying nitrogen, improves root environment, increasing water and nutr...
Arranjos de cultivo de soja, cruzada e convencional, submetida a doses e manejo...
Couto Junior, Pedro AfonsoBrazilian soybeans have high productivity which is similar to those obtained in developed countries. Such prominent position is also due to investment in management systems. One potential option for increasing yield is the adoption of denser planting spatial designs and improvement of fertilizer supplying efficacy, with effective application modes that optimize time. Therefore, the purpose was to evaluate the e...
Espaçamentos e manejo na produção de híbridos de melancia em duas épocas
Campos, Antônio Marcos DinizAlthough Brazil is the fourth watermelon (Citrullus lanatus) producing country in ranking position, its greatest challenge is the low yield average obtained (22.5 t ha-1). Such yield, places Brazil in the 38th position in the world rank, reflecting the amount of effort still needed to increase Brazilian yield efficiency. Thus, greater knowledge about the agronomic traits of new cultivars is relevant to obtain m...
