14. Parametrização de Modelos e Uso de Dados Estimados de Radiação Solar Global na Simulação de Produtividade do Arroz Irrigado
Resumo O objetivo deste estudo foi avaliar a utilização de dados estimados de radiação solar global nas simulações de produtividade potencial de arroz irrigado. A radiação solar global foi estimada por quatro modelos empíricos, baseados na temperatura do ar, e um derivado de satélite meteorológico. Os modelos empíricos foram calibrados e validado

15. Effects of Long-Term Fertilization Management Practices on Soil Microbial Carbon and Microbial Biomass in Paddy Soil at Various Stages of Rice Growth
ABSTRACT Soil microbial biomass plays a significant role in soils, and it is often used as an early indicator of change in soil quality. Soil microbial biomass is affected by different fertilization management practices. Therefore, the impact of different long-term fertilization management practices on the soil organic carbon (SOC) content, soil microbial bi

16. A perfect functional marker for the gene of intermediate amylose content Wx-in in rice (Oryza sativa L.)
Abstract The amylose content (AC) of rice is a key determinant of the grain cooking and eating quality. The Waxy (Wx) gene, which encodes granule-bound starch synthase I (GBSSI), is the major gene controlling AC in rice. The A - C substitution in exon 6 (Ex6A/C) alters the amino acid codon from serine to tyrosine and is associated with intermediate-AC rice (

17. Comet and cytogenetic tests as tools for evaluating genomic instability in seeds of Oryza sativa L. and Phaseolus vulgaris L. from gene banks
Abstract This study aimed to assess the feasibility of comet and cytogenetic tests as tools for evaluating genomic instability in seeds of Oryza sativa L. (rice) and Phaseolus vulgaris (beans) L. from gene banks. Rice and beans were exposed to methyl methanesulfonate (MMS) as a reference DNA damaging agent. Seeds of two accessions of rice and beans were obta

18. Performance of Flooded Rice Grown in Succession to Winter Cover Crops
ABSTRACT: Mean grain yield of flooded rice in southern Brazil has increased in recent years due to the use of high-yield cultivars and improvement of crop management practices. Nevertheless, stagnation in grain yields has been observed in some rice-producing regions. Adoption of conservation tillage systems based on cover crops may be a strategy to increase

19. Returning Winter Cover Crop Residue Influences Soil Aggregation and Humic Substances under Double-cropped Rice Fields
ABSTRACT Residue management in cropping systems may improve soil quality. However, there are few studies on the effects of residue management on soil aggregation and carbon content in the humin (C-HUM), humic acid (C-HAF) and fulvic acid (C-FAF) fractions in South China. Therefore, the effects on soil aggregation and on the C-HUM, C-HAF, C-FAF from incorpora

20. Molecular Characterization of a MYB Protein from Oryza sativa for its Role in Abiotic Stress Tolerance
ABSTRACT The MYB family represents one of the most abundant classes of transcriptional regulators that perform pivotal role under different developmental processes and abiotic stresses. In present study, a MYB gene from Oryza sativa was selected for functional characterization. Bioinformatics analysis revealed that OsMYB1 cDNA encodes R2-R3 type DNA binding

21. 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

22. A walk on the wild side: Oryza species as source for rice abiotic stress tolerance
Abstract Oryza sativa, the common cultivated rice, is one of the most important crops for human consumption, but production is increasingly threatened by abiotic stresses. Although many efforts have resulted in breeding rice cultivars that are relatively tolerant to their local environments, climate changes and population increase are expected to soon call f

23. Rhizobial Inoculation, Alone or Coinoculated with Azospirillum brasilense, Promotes Growth of Wetland Rice
ABSTRACT Rhizobia and associative bacteria promote growth in rice plants (Oryza sativa L.) through a series of mechanisms, but most studies on inoculation have been performed based on inoculation with these bacteria in a separate or singular manner. The objective of this study was to assess the efficiency of single/isolated inoculation and inoculation combin

24. Evaluation of the technological, nutritional and sensory qualities of bakery products produced with partial substitution of the wheat flour by whole rice flour
Summary The objective of this work was to determine the technological, nutritional and sensory characteristics of bread produced by substituting 25 and 50% of conventional wheat flour by whole rice flour (Oryza sativa L). The final products were evaluated in terms of specific loaf volume, appearance of the central slice, crumb firmness, moisture content, die
