1. Patterns recognition methods to study genotypic similarity in flood-irrigated rice
ABSTRACT Genetic diversity studies are performed based on information on a set of traits measured in a group of genotypes, considering one or more environments. The pattern recognition methods allow classifying genotypes from a set of important agronomic information. Thus, this study aimed to present and compare pattern recognition methods to inquire about t

4. Introducing rice yield loss caused by weed competition into the SimulArroz model
Resumo: O objetivo deste trabalho foi modelar a competição de arroz-daninho (Oryza sativa) e capim-arroz (Echinochloa spp.) com o arroz irrigado por inundação e introduzi-la como um submodelo no modelo SimulArroz. A competição das duas ervas daninhas com o arroz irrigado foi modelada com o uso da equação da hipérbole retangular. Os coeficientes “i

5. Occurrence of rice blast on and grain quality of irrigated rice fertilized with nitrogen and silicates
Resumo: O objetivo deste trabalho foi avaliar os efeitos da adubação com nitrogênio em cobertura e silicatos, bem como da utilização de fungicidas, sobre a ocorrência de brusone nas panículas, a renda do benefício e os grãos inteiros, vítreos e gessados, em cultivar de arroz irrigado por inundação sensível à doença. Foram conduzidos dois exper

6. Leaching of Imidazolinones in Irrigation Systems in Rice Cultivation: Sprinkling and Flooding
RESUMO: Herbicidas do grupo das imidazolinonas têm sido utilizados em arroz irrigado e apresentado longa persistência no solo, principalmente em áreas de várzea, com baixa drenagem, podendo ocasionar contaminação ambiental. Objetivou-se, com este trabalho, avaliar a lixiviação e o residual dos herbicidas pertencentes ao grupo das imidazolinonas em si

7. Performance of flood-irrigated rice as affected by residual rice straw1
RESUMO Desempenho de arroz irrigado por inundação afetado por palha residual de arroz O arroz é uma cultura de importância econômica e alimentar que atinge elevada produtividade em cultivos irrigados por inundação. No entanto, a quantidade de palha residual do cultivo anterior pode influenciar no seu crescimento e produtividade. Objetivou-se avaliar o

8. INTERMITTENT AND CONTINUOS FLOODING IN RICE: WATER USE, AGRONOMIC EFFICIENCY AND IMAZETHAPYR, IMAZAPIC AND FIPRONIL DISSIPATION / IRRIGAÇÃO CONTÍNUA E INTERMITENTE EM ARROZ IRRIGADO: USO DE ÁGUA, EFICIÊNCIA AGRONÔMICA E DISSIPAÇÃO DE IMAZETHAPYR, IMAZAPIC E FIPRONIL
Every anthropogenic activity causes environmental impact in some extent. Rice paddy fields area are pointed out as an activity with high potential of pollution due to the large amount of water used to maintain the flooding and the intensive use of pesticides and nutrients that can be transported to the environment. Though, there are other irrigation manageme

9. ADEQUAÇÃO DA DEMANDA HÍDRICA E DA POTÊNCIA INSTALADA EM SISTEMAS DE RECALQUE PARA O ARROZ NA DEPRESSÃO CENTRAL DO RIO GRANDE DO SUL. / ADJUSTMENT OF THE HYDRIC DEMAND AND INSTALLED POWER OF PUMPING STATION FOR RICE OF THE CENTRAL DEPRESSION IN RIO GRANDE DO SUL
É incontestável a relevância da cultura do arroz para a economia do Rio Grande do Sul. São plantados anualmente em torno de um milhão de hectares, os quais são irrigados por inundação contínua, exigindo elevada demanda hídrica. O suprimento hídrico do cultivo é atendida em 70% da área através de sistemas de recalque (bombeamento), representando

10. Nitrogen-Fixing (Acetylene Redution) Activity and Population of Aerobic Heterotrophic Nitrogen-Fixing Bacteria Associated with Wetland Rice
Nitrogen-fixing activity associated with different wetland rice varieties was measured at various growth stages by an in situ acetylene reduction method after the activities of blue-green algae (cyanobacteria) in the flood water and on the lower portion of the rice stem were eliminated. Nitrogen-fixing activities associated with rice varieties differed with

11. Expression of an ortholog of replication protein A1 (RPA1) is induced by gibberellin in deepwater rice
Internodes of deepwater rice are induced to grow rapidly when plants become submerged. This adaptation enables deepwater rice to keep part of its foliage above the rising flood waters during the monsoon season and to avoid drowning. This growth response is, ultimately, elicited by the plant hormone gibberellin (GA). The primary target tissue for GA action is

12. GénoPlante-Info (GPI): a collection of databases and bioinformatics resources for plant genomics
Génoplante is a partnership program between public French institutes (INRA, CIRAD, IRD and CNRS) and private companies (Biogemma, Bayer CropScience and Bioplante) that aims at developing genome analysis programs for crop species (corn, wheat, rapeseed, sunflower and pea) and model plants (Arabidopsis and rice). The outputs of these programs form a wealth of
