Resistência parcial e fungicidas no controle da ferrugem asiática da soja
Silva, Valdirene Aparecida StabileSoybean asian rust, caused by the fungus Phakopsora pachyrhizi, is one of the major pest problems in the crop. Disease control has required a combination of cultural practices to minimize losses. Among the control methods, chemical control with fungicides, has been the only one available. Control strategies, such as the use of cultivars with partial resistance to the fungus are desirable for an effective diseas...
Silicato de potássio aplicado via foliar e a incidência da brusone em arroz
Buck, Guilherme BossiFundação de Amparo a Pesquisa do Estado de Minas Gerais; Silicon (Si) is now recognized as a beneficial element for the plants. The direct and indirect benefits of the element for the cultures (mainly grasses) are related to tolerance to diseases, pests and to water stresses. As most of these studies were done with fertilizers applied to the soil, studies related to the efficiency of the plants in absorbing Si ...
Adaptabilidade e estabilidade de genótipos de soja em Minas Gerais
Correia, Wanessa RosaThe objective of this work was to analyze the stability and adaptability of 11 soybean genotypes, where 8 lines belonged to the Soybean breeding program of UFU and 3 commercial cultivars were used as controls: M-Soy 8400, MG/BR-46 Conquista and M-Soy 6101. The experimental design used was randomized blocks, with three replications. The study was done in 2004/2005 and 2005/2006 harvest in Uberlândia and Uberaba ...

Oliveira, Angelo Fernandes deCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Of macronutrients cited in scientific literature, the potassium is the element that presents consistent positive results in the reduction the incidence of pests and diseases. Reports show that nutrition potassica adequately reduced the severity of more than 20 diseases bacterial, more than 100 diseases fungal and of 10 diseases caused by viruses and n...
Variabilidade intra-específica em Lithraea molleoides (Vell.) Eng. (Aroeira-Bra...
Berger, Ana Paula de AguiarThe great diversity of morphology in diaspores of Anacardiaceae reflects in germination and dormancy processes and generates a differentiated behavior among species. There are some species within this family that show physical dormancy, others show mechanical dormancy, some that do not show dormancy and also species that lack this information in the available literature. Lithraea molleoides is among the species...
Variabilidade de cinco espécies arbóreas da região de cerrado do Brasil Central...
Ferreira, Wanessa ResendeBasic studies of seed germination and seedling emergence assume an important role within scientific researches due to the devastation and fragmentation of the native vegetation of the Cerrado. Thus, in the present study the processes of seed germination and seedling emergency were evaluated using the linear correlations among the measurements calculated for five Cerrado species. The individual contribution for ...
Adaptabilidade e estabilidade de genótipos de soja em Goiás nos anos 2004/2005
Franco, Poliana BorgesThis work had the objective to evaluate the performance of soybean lines, come from the Program of Genetic Improvement of soybean of the Federal University of Uberlândia, in regional tests of evaluation of lines in the cities of Goiatuba, Rio Verde, Bela Vista, Campo Alegre and Porangatu, in the State of Goiás. 27 lines of delayed cycle had been evaluated and having as witnesses to cultivate them M-Soy 866, Gua...
Qualidade da semente de soja tolerante ao glifosato, produzida em condições fav...
Silva, Fernanda FavoretoThis work has aimed to evaluate the quality of glyphosate-tolerant seeds of soybean genotypes of early, mid-, and late season, produced in adequate conditions. Experiments took place in two phases. Firstly, in a field one, with three variety competition trials; 6 glyphosate-tolerant genotypes of soybean were evaluated: early season (BR01-71210, BR02-64301, BRSMG 750SRR, BRS Favorita RR, BRS Valiosa RR e M-Soy 8...
Resposta do cafeeiro (Coffea arabica L.) à lâminas de irrigação por gotejamento
Silva, César Antônio daThis study evaluated coffee plant Ruby, line MG-1192, vegetative development, yield and berry quality, cultivated under irrigation levels during five years. The experiment was done in a loamy red latosol, at Experimental Farm of Glória, located to 18º58 S and 48º12 W, and approximately 890 m above sea level, in the county of Uberlândia, in Minas Gerais, Brazil. The local climate is Cwa, with dry winter and hot ...
