Utilização de molibdênio via foliar no enriquecimento de sementes de soja
Fonseca, Fernando CavicchioliThe use of Mo rich seeds is an alternative for supplying Mo that has presented consistent results on increasing NBF and soybean yield. Soybean enrichment with molybdenum was analyzed through leaf application during the reproduction stage, as potassium molybdate, to optimize its use in soybean culture. The experiment was done on a sandy soil, classified as a neosol, located at the Fazenda Adriana, in the county ...
Análise de experimentos de germinação usando os modelos lineares generalizados
Carvalho, Fábio JanoniCHAPTER II: Analysis of variance (ANOVA) is one of the most important statistical models applied in agronomic experiments, especially in the seeds area. Based on strong assumptions, it lasted for many years with the support of techniques such as data transformation. As ANOVA being a special case of Generalized Linear Models (GLM), a classic experiment of seeds germination of tree species Copaifera langsdorffii ...
Proporção de material orgânico no substrato artificial na produção de mudas de ...
Dias, RicardoUtilization of organic materials might contribute to reduce costs of production and enhance vegetative development and quality of coffee seedlings. With the objective of evaluating the effects of the utilization of different organic materials on the standard substrate used for coffee seedlings production, (Coffe Arabic L.), an experiment was conducted at the Agrotecnical Federal Scool -EAFU in Uberlândia, MG, B...
Seleção indireta em genótipos de tomateiro para tolerância ao estresse hídrico
Berenguer, Andrea FarnezeThe objective was to define an efficient method of indirect selection for tolerance to water stress and use it as a screening method in tomato genotypes F2RC1. The experiments were conducted at the Seed Analysis Laboratory and Genetic Resources and the Experimental Station of vegetables, the Federal University of Uberlândia in Monte Carmelo. At first it was assessed how best concentration of Mannitol able to id...
Germinação e estabelecimento inicial in vitro de Lavandula angustifolia
Oliveira, Rayssa Camargo deCAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior; FAPEMIG - Fundação de Amparo a Pesquisa do Estado de Minas Gerais; The plant tissue culture techniques includes a set in which each explant (cell, tissue or organ) is isolated under aseptic conditions on artificial nutrient medium. This process is based on the principle of totipotentiality cells, or any plant organism cell has all the genetic ...
Déficit hídrico em tipos de crescimento da soja
Machado Júnior, Carlos SebastiãoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Studies involving the impact of water stress on soybean physiology are abundant, but the studies about determinate and indeterminate growth types are scarce. Considering that the responses of growth types to water stress are of great value to guide drought resistance breeding programs, the aim of this study was to evaluate soybean physiologic paramete...
Seletividade de herbicidas na cultura da batata
Fonseca, Luciano Ferreira daWeed competition occurs during potato planting and development, demanding for the application of specific herbicides, especially pre-emergent ones. There are few herbicides registered for this crop and the cultivars present different selectivity levels to them. Thus, the study of selectivity and weed management are fundamental for obtaining high yields. This study evaluated the selectivity and weed control with...
Desenvolvimento de mudas de maracujazeiro amarelo e tubetes
Silva, Ana Paula Pereira daA major part of the success of a crop is related to the use of seedlings of good quality. Little information is found in agricultural literature regarding certain details in the production of yellow passion fruit seedlings in tubettes, which makes the activity for seedling producers quite difficult. The present research had, as a general objective, to extend the knowledge of the production of yellow passion fru...
Análise dialélica de Jinks & Hayman em genótipos de algodoeiro
Vieira, Fernanda Almeida de CarvalhoThis research aimed at the estimation of genetic parameters in a diallel cross according to the methodology developed by Jinks & Hayman. The experiment was conducted in an experimental area of the Agronomy Dept. of the ILES/ULBRA University, at Itumbiara, Goiás, Brazil in 2003. Treatments tested comprised the eight parental cultivars and their 28 hybrid combinations. The following traits were submitted to the J...
Indução de calos e embriogênese em anteras de Coffea arabica L.
Silva, Adelaide SiqueiraCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; Coffee breeding through convention methods, especially hybridization, followed by population selection, progeny evaluation, back-crossings and inter-specific crossings is a time consuming process that can demand for more than 30 years to obtain a new cultivar. It is possible to reduce this time by producing homozygous lines, from di-haploids, obtained...
