1. Genetic variability and breeding potential of Flintisa Composite of maize in two levels of technology
Abstract The purpose this study was to verify the breeding potential of Flintisa Composite for low (LT) and high (HT) technology of cultivation, and the best selection strategy to be adopted. For this reason half-sib progenies were evaluated in the two technological levels. In HT, it was used basic fertilization, two top dressing and supplementary irrigation

2. FREQUÊNCIA E ÉPOCA DE APLICAÇÃO DE FUNGICIDAS E SEUS EFEITOS EM HÍBRIDOS DE MILHO (Zea mays L.) / FREQUENCY AND TIME OF APPLICATION OF FUNGICIDES AND ITS EFFECTS IN THE HYBRIDS MAIZE (Zea mays L.)
Among the major diseases with potential for reducing the final yield of maize (Zea mays) are common rust (Puccinia sorghi), and Spot Blotch (Exserohilum turcicum). Seed companies offer hybrids with levels of disease resistance in the shoots, however, these have demonstrated the need for alternatives that help to maintain the low rate progress of diseases. Gi

3. Resposta de híbridos de milho cultivados em diferentes épocas à população de plantas e ao despendoamento / Response of maize hybrids grown at different eras to plant population and tassel removal
Os híbridos contemporâneos de milho são mais tolerantes à elevação da população de plantas do que os híbridos antigos. É possível que a melhor adaptação da cultura ao adensamento esteja relacionada com a menor dominância apical do pendão sobre a espiga. Este trabalho foi conduzido objetivando avaliar a evolução na tolerância de híbridos de

4. O corpo e a máquina: um terreno de experiência, a clínica do adolescente¹
A partir de estudo de casos em clínica com adolescentes, procuramos identificar os aparatos simbólicos da linguagem contemporânea, no que concerne à construção da identidade. As tecnologias disponíveis são utilizadas pelos adolescentes como elementos de alteridade em que a afirmação da sexualidade desvanece sob o emaranhado de "próteses da linguag

5. Bayesian inference on field data for genetic parameters for some reproductive and related traits of Nellore cattle (Bos indicus)
We used Gibbs sampling in single and two-trait animal models to estimate genetic parameters for some reproductive and related traits of Nellore cattle (Bos indicus). Female traits were age at first calving (AFC), cumulative productivity (CP) and adult weight (AW). For males, scrotal circumferences at 365 and 450 days of age were analyzed. Gibbs sampling usin

6. Intergenotypic interaction in maize x beans intercropping / Interação intergenotípica no consorciamento milho x feijão
The objective of this work was to study the intergenotypic interaction in a maize and beans intercropping system; to study the application of techniques used in the assessment of genotype x environment interactions to the study of genotype x genotype interactions; to verify the possibility of using a autogamous species (beans) as an environmental indicator f

7. Aplicação foliar de nitrato e de microorganismos eficazes (EM) e seus efeitos sobre a partição de nutrientes em variedades de milho (Zea mays L.) cultivadas com resíduo industrial / Nitrate and effective microorganisms (EM) foliate application and the effects on the nutrient partition in corn varieties (Zea mays L.) cultivated with industrial residue
Nitrate and the microorganism solution (EM), in different treatments, were applied to the foliage of the Sol da manhã and BRS 1010 corn varieties, in order to evaluate nutrients level in different parts of the plants (vegetative and reproductive). It was also evaluated the possibility of the usage of an industrial residue, generated from the production of l

8. Management of Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) on corn, Zea mays L.: basis for populational evaluation and biological control using the egg parasitoid Trichogramma atopovirilia Oatman &Platner, 1983 (Hymenoptera: Trichogrammatidae). / Manejo de Spodoptera frugiperda (J.E. Smith, 1797) (Lepidoptera: Noctuidae) em milho, Zea mays L.: bases para avaliação populacional e controle biológico utilizando o parasitóide de ovos Trichogramma atopovirilia Oatman &Platner, 1983 (Hymenoptera:Trichogrammatidae)
The objectives of this research were the improvement of cross-section Spodoptera frugiperda using pheromone traps to verify the capacity of dispersion of Trichogramma atopovirilia as an agent for biological pest control as well as evaluating the attractiveness of Amaranthus sp. to T. atopovirilia females. To improve cross-section of S. frugiperda, the studie

9. Efeito do retardamento da colheita sobre a qualidade fisiológica de sementes de aveia-branca (Avena sativa L.)
Com o objetivo de avaliar o efeito do atraso da colheita na qualidade fisiológica de sementes de quatro cultivares de aveia-branca (Avena sativa L.), foi instalado um experimento no Centro Agropecuário da Palma CAP/UFPel, no ano agrícola 1999/2000. Utilizou-se uma combinação fatorial de quatro cultivares (CTC 5, UPF 18, UFRGS 15 e UFRGS 19) e sete époc

10. Heterochronic Effects of Teopod 2 on the Growth and Photosensitivity of the Maize Shoot.
Teopod 2 (Tp2) is a semidominant mutation of maize that prolongs the expression of juvenile vegetative traits, increases the total number of leaves produced by the shoot, and transforms reproductive structures into vegetative ones. Here, we show that Tp2 prolongs the duration of vegetative growth without prolonging the overall duration of shoot growth. Mutan

11. Experimental Analysis of Tassel Development in the Maize Mutant Tassel Seed 6.
The maize (Zea mays L.) mutation Tassel seed 6 (Ts6) disrupts both sex determination in the tassel and the pattern of branching in inflorescences. This results in the formation of supernumerary florets in tassels and ears and in the development of pistils in tassel florets where they are normally aborted. A developmental analysis indicated that extra florets

12. Developmental and Thermal Regulation of the Maize Heat Shock Protein, HSP1011
The plant heat stress protein, Hsp101, and the yeast ortholog, Hsp104, are required to confer thermotolerance in plants and yeast (Saccharomyces cerevisiae), respectively. In addition to its function during stress, Hsp101 is developmentally regulated in plants although its function during development is not known. To determine how the expression of Hsp101 is
