Estádio de maturação dos frutos, tratamentos pré-germinativos e variabilidade d...
Anastácio, Maristela RosáliaThe objective of this work was to evaluate the influence of the fruit maturation stage in the physical attributes and germination of Schefflera morototoni pyrenes subjected to pre-germination treatments. Fruits with green and purplish green coloration were collected from 14 individuals, pulped in running water, the hollow pyrenes were discarded after counting, together with those presenting retracted and oxidiz...
Estabelecimento in vitro, aclimatização e conservação in vitro de Lippia alba (...
Santos, Verônica AraújoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; This study analyzed in vitro establishment, acclimatization and conservation of Lippia alba (Mill.) N. E. Brown. For this purpose, the effect of different concentrations and dipping times of sodium hypochloride in sterile explants was tested. Nodal segments were immersed in sodium hypochloride at different concentrations (0.4, 0.6, 0.8 and 1.0%) and d...
Métodos de inoculação e avaliação da resistência de genótipos de soja à Sclerot...
Sagata, ÉrikaConselho Nacional de Desenvolvimento Científico e Tecnológico; Soybean stem white rot, caused by Sclerotinia sclerotiorum, occurs in more than one million hectares in Brazil. This disease should be managed by integrated control methods, including genetic resistance. This study evaluated and developed a reliable method for the selection of soybean genotypes resistant to stem white rot. The work was based on rati...
Atributos físicos de Latossolo cultivado com cana-de-açúcar e adubado com dejet...
Gomides, Juliana do NascimentoFundação de Amparo a Pesquisa do Estado de Minas Gerais; The cultivation of sugarcane is in strong expansion in the Cerrado region, requiring management techniques to maintain the soil physical quality. The use of animal s manure from intensive husbandry constitutes an alternative to reduce the physical degradation of the poor soil use due to lower cost with chemical fertilizations and, mostly, making possible ...
Reação de cultivares de Phaseolus vulgaris L. aos fitonematóides de importância...
Perre, JulianaPhytosanitary problems, among other factors, are the main cause of low productivity in the common beans crop. The presence of nematodes in the crop is a direct cause of low yield. The reproduction of the nematodes Heterodera glycines race 3, Melodogyne incognita, M. javanica and Pratylenchus brachyurus was evaluated in eleven bean cultivars under greenhouse conditions. A completely randomized design with six re...
Produção de biomassa e óleo essencial de manjericão (Ocimum basilicum L.) em di...
Resende, Renata Ferreira deBasil is mostly grown, in Brazil, by small farmers to sell the leaves. Climate factors play an important role on the development of medicinal, aromatic and condiment plants and on the production of active ingredients. This study analyzed the production of biomass and essential oil of basil (Ocimum basilicum L.) grown in different seasons, growth environments and fertilizations in Uberlândia, MG. Two experiments...
Uso de resíduos orgânicos na composição de substratos alternativos para a produ...
Rezende, Josielle SantosFundação de Amparo a Pesquisa do Estado de Minas Gerais; The use of organic residues as components of substrates allow obtaining alternative materials, easily obtained, constantly available and of low cost, aiding on the minimization of pollution resulting from residue accumulation in the environment. Therefore, this study evaluated the quality of substrates formulated with organic residues on the process of em...
Eficiência de aplicação do herbicida 2,4-d amina com diferentes volumes e ponta...
Souza, Lélio Augusto dePesticide spray technology aims the uniform deposition of products in the target, with minimal losses to se soil or drift, which may have consequences in agricultural areas. In this context, the herbicide 2,4-D Amina represents a product with great environmental concern, but still widely used in modern agriculture. Thus, to obtain greater infesting plants control during desiccation, this study evaluated the spr...
Tecnologia de aplicação aérea e terrestre na cultura da batata
Bueno, Mariana RodriguesFundação de Amparo a Pesquisa do Estado de Minas Gerais; Potato is the main vegetable cultivated in Brazil, however, this crop shows great problems concerning to pesticide application technology. These high frequency of product application, specially fungicides, is responsible for increasing the costs of production. Therefore, it is necessary to study methods that may optimize the technology by which pesticides...
Qualidade fisiológica de cipselas de girassol das cultivares Helio 360 e Helio 250
Oliveira, Rafael Brito deCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; The few research papers relating to the possible advantages of acquiring sunflower cypselas of certain sizes diverge as to the results. This fact awakens interest as much on the part of researchers as on those producing seeds. So it is necessary to analyze, in laboratory and field conditions, the physiologic quality of different widths sunflower cypse...
