1. Determination of the most susceptible phenological stage of rice panicles to infection by species of Fusarium graminearum
RESUMO A ocorrência de sementes de arroz infectadas por Fusarium graminearum mostra a importância de identificar o estágio fenológico da panícula mais favorável à infecção dos grãos. Os experimentos foram realizados em duas safras em condições de casa de vegetação, utilizando o híbrido de arroz INOV CL. Os estádios fenológicos durante a inoc

2. Visualized protein polymorphisms in leaf sheaths and roots of rice assessed by 2-DE analysis
Abstract To identify potential protein markers associated with tillering in rice, a d10 allelic mutant (JHCA) with a high-tillering dwarf phenotype and a wild-type cultivar (GLA4) with normal numbers of tillers were used to produce a hybrid (F1), and 2-DE (two-dimensional electrophoresis) analysis was conducted in seedling leaf sheaths and roots of the rice

3. Symptoms of Fusarium graminearum infection in irrigated rice grains
RESUMO: O fungo Fusarium graminearum foi um dos primeiros patógenos descritos na cultura do arroz, no entanto, no Brasil, não há descrição de sua ocorrência em panículas. O objetivo desse estudo foi descrever os sintomas ocasionados pela infecção de F. graminearum em grãos de arroz irrigado. O experimento foi conduzido, em casa de vegetação, dua

4. Late nitrogen application enhances spikelet number in indica hybrid rice (Oryza sativa L.)
ABSTRACT To increase rice yield potential, field experiments were conducted in farmers’ paddies in 2011 and 2012 to evaluate the effects of different nitrogen applications on the yield and panicle components of three typical indica hybrid rice varieties in Sichuan Province. The number of grains per panicle resulting from late nitrogen application (LA) was

5. Termodinâmica de condensados aprisionados em armadilhas óptico-magnéticas / Thermodynamic studies on BECs trapped by hybrid traps
In this master thesis we present some preliminary studies on the Thermodynamics of ultracold gases in inhomogeneous potentials. These studies were performed in two different experimental setups using the new global variables proposed by V. Romero-Rochín, which we call volume parameter and pressure parameter. The first system is the experiment built in our l

6. Performance of super hybrid rice cultivars grown under no-tillage and direct seeding
Good progress has been made in the super hybrid rice (Oryza sativa L.) breeding in China. However, rice yield not only depends on the genetic characteristics but also on the agronomic practices. No-tillage and direct seeding (NTDS) is a simplified cultivation technology that greatly simplifies both land preparation and crop establishment. Aiming to determine

7. THE HYBRID BOUNDARY ELEMENT METHOD BASED ON GENERALIZED WESTERGAARD STRESS FUNCTIONS / O MÉTODO HÍBRIDO DOS ELEMENTOS DE CONTORNO COM BASE EM FUNÇÕES DE TENSÃO DE WESTERGAARD GENERALIZADAS
A particular implementation of the hybrid boundary element method is presented for the two dimensional analysis of potential and elasticity problems, which although general in concept, is suited for fracture mechanics applications. Generalized Westergaard stress functions, as proposed by Tada et al in 1993, are used as the problem¿s fundamental solutions. T

8. Sensory analysis as a tool to support rice breeding research: a comparison between hybrid rice and conventional commercial rice.
This study aims to assess sensory differences between a hybrid variety sample and conventional commercial rice samples by the Difference from Control Method. This method provides information on the size of the difference between a control and other samples

9. Mapping of quantitative trait loci for thermosensitive genic male sterility in indica rice.
The objective of this work was to select and use microsatellite markers, to map genomic regions associated with the genetic control of thermosensitive genic male sterility (TGMS) in rice. An F2 population, derived from the cross between fertile and TGMS indica lines, was used to construct a microsatellite-based genetic map of rice. The TGMS phenotype showed

10. Análise da heterose de cruzamentos entre variedades de arroz-vermelho.
O objetivo deste trabalho foi avaliar, por meio de análise dialélica, o potencial de dez variedades de arroz-vermelho para a implementação de um programa de melhoramento. A identificação de genitores foi feita com dez variedades, em um cruzamento dialélico completo sem recíprocos. As variedades e seus 45 cruzamentos foram avaliados nas gerações

11. Estudo comparativo entre a viabilidade de implantação de sistema híbrido eólico-diesel e de extensão de rede elétrica em regiões remotas produtoras de arroz por sistema de inundação
O presente estudo compara a viabilidade de implantação de um sistema híbrido eólicodiesel nos arredores de Santa Vitória do Palmar, para uma família de pequenos produtores de arroz, com a viabilidade de extensão de rede elétrica até o local. A demanda e consumo energético da família estão estimados em 42696W e 54404kWh/ano. Compara-se, através d

12. A new approach for obtaining rapid uniformity in rice (Oryza sativa L.) via a 3x x 2x cross
A triploid (2n = 3x = 36) rice plant was obtained by screening a twin seedling population in which each seed germinated to two or three sprouts that were then crossed with diploid plants. One diploid plant was chosen among the various F1 progenies and developed into an F2 population via self-pollination. Compared with the control variety Shanyou 63, this F2
