Marcadores morfológicos e moleculares na identificação e distinção de off-type ...
Andrade, Vinicius deMorphological markers are useful tools for identifying off-type (atypical plants) in seed production fields. However, environmental factors can cause changes in certain individuals phenotype, turning molecular markers into useful tools for verification of possible genotypic differences between these individuals and the variety studied. The aim of this study was to evaluate the efficiency of SNP markers in ident...
Formas de adição de micronutrientes a um formulado NPK e seu efeito sobre o des...
Santos, Gustavo AlvesMicronutrients are required in small amounts by plants and are essential for their development; however, micronutrient content in soil often is not sufficient to ensure high productivity, which creates the need for its application through fertilizers. This study compared availability of boron, copper, manganese and zinc to the soil, their absorption, accumulation and effect in developing maize plants, supplied ...
Fontes de fósforo na implantação de sistema integração lavoura-pecuária-florest...
Franco, Fernando OliveiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; The soil is a complex system susceptible to degradation. Its degradation is an evolutionary process, starting with the conversion of natural systems into production systems. Currently, in search of non-degradation of natural systems, production systems are under continuous advancement in the quest for sustainability. The new reality requires a product...
Época de semeadura e local de produção na germinação de sementes do algodoeiro
Pereira, Marcelo OliveiraThe place where cotton-plant is cultivated to produce seeds and its sowing time are extremely important, especially due to local climatic conditions. Based on this premise, this work aimed at verifying the influence distinct epochs of sowing in two different places had on the germination of cottonseed genotypes in the season 2007/2008. This study was carried out in two municipalities: Itumbiara, Goiás state, an...
Rochagem como alternativa para fornecimento de potássio para as culturas
Santos, Douglas da SilvaFundação de Amparo a Pesquisa do Estado de Minas Gerais; In order to evaluate the use of rock powder and rock thermally treated applied as an alternative source of potassium for crops, three studies were conducted: Incubation study, biological study and leaching study. All studies were conducted in a greenhouse, using samples of two types of soils, an Oxisol Red (LVd) and a Ustoxic Quartzipsamment (RQo). The fi...
Estabelecimento in vitro do baruzeiro (Dipteryx alata Vog.)
Pinhal, Hernane FernandesCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; CHAPTER II: This study determined an efficient method of using sodium hypochlorite and the antibiotic rifampicin in the decontamination process for the establishment in vitro of baruzeiro (Dipteryx alata Vog.) explants. Baruzeiro seeds were brought to the Plant Tissue Culture Laboratory of the Universidade Federal de Uberlândia and, under aseptic cond...
Comportamento agronômico do milho em resposta ao modo de aplicação e concentraç...
Sá Júnior, Adílio deThe use of Azospirillum genus bacteria to fix nitrogen can be useful to obtain such chemical element and, thus, reduce costs of maize cultivation. This study aimed to evaluate changes of morphological components in the production and productivity of maize as a response to application methods and concentration of Azospirillum brasilense. The experiment was carried out at Gloria experimental farm, linked to Unive...
Métodos AMMI, GGE BIPLOT, REML/BLUP e análise de fatores na estabilidade e estr...
Martinelli, André PauloThe present study evaluated the effects of genotype by environment interaction, adaptability, stability, selection of the best maize hybrids, and to stratify the most suitable environments for selection of genotypes adapted to second harvest in Central Brazil, by the methods AMMI (Additive Main Effects and Multiplicative Interaction Analysis), GGEbiplot (Genotype and Genotypes by Environment Interaction), AF (F...
Quantificação de escleródios e germinação miceliogênica e carpogênica de Sclero...
Crato, Fausto Fernandes doCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Sclerotinia stem rot caused by Sclerotinia sclerotiorum is spreading every year in soybean fields. Due to the survival capacity in soil using specialized structures, called sclerotia, and environmental conditions favorable for germination, the use of Integrated Disease Management is essential. Better understanding of pathogen biology is obtained by qu...
Monitoramento dos atributos físicos do solo e produtividade de cana-de-açúcar e...
Arruda, Everton MartinsFundação de Amparo a Pesquisa do Estado de Minas Gerais; This study evaluated the behavior of soil physical properties in growing plant sugarcane and ratoon cane in a Typic Haplustox soil under different tillage systems. The experiment was done in the Cerrado region, at Usina Jalles Machado, in 2009, with sugarcane variety CTC 02. The experimental design was randomized blocks (RBD), and soil total porosity, mac...
