Toxic elements, essential elements and other were determined in Brazilian rice by inductively coupled plasma-mass spectrometry (ICP-MS). A method for As speciation using hydride generation was developed applied samples.
Improved seed priming techniques can reduce time between sowing and seedling emergence, resulting in rapid uniform seedlings high vigor, better stand establishment, allometric yields many field crops.The objective of this research was to understand the effects hydropriming on rice physiological potential crop performance for upland systems.Therefore, laboratory trials were carried out.Initially, two lots from varieties used create imbibition curves, required establish protocols.The protocols...
Abstract Embrapa has led breeding programs for irrigated and upland rice ( Oryza sativa L.) since 1977, generating a large amount of pedigree phenotypic data. However, there were no systematic standards data recording nor long‐term preservation reuse strategies. With the new aim making practical, we recovered all available structured it into Rice Breeding Dataset (ERBD). In its current version, ERBD includes 20,504 crosses involving 9,974 parents, pedigrees most 4,532 inbred lines that took...
O objetivo do trabalho foi avaliar, fenotipicamente, as cultivares de arroz tradicionais Guarani e Caiapó, modernas, CIRAD L(-1)41, Maravilha, BR IRGA 409 Metica 1, por meio da associação entre os vários componentes produtividade grãos, para prover base seleção genética em populações plantas. estudo conduzido na estação chuvosa ano agrícola 2003-2004, área experimental Embrapa Arroz Feijão, Santo Antônio Goiás, GO. Em condições sequeiro, com suplementação hídrica, terras altas Guarani,...
The cultivation of hybrid rice is a technology that allows for an increase in grain yield 30% relative to the conventional cultivars. However, main challenge this related seed production, which has high production costs and low yields. Therefore, agronomic techniques could enhance flowering synchrony parental lines field are essential efficient system seeds. objective work was study effects sowing depth, plant density fertilization with nitrogen or phosphorus as potential pollen availability...
Background: Adoption of the hybrid rice varieties by farmers is often impaired high price seed, due to low yields in seed production fields. Female outcrossing ability (FOA) and female (FHSPA), defined as rate filled spikelets male sterile (MS) line its grain yield under outcrossing, respectively, determine plant traits for yield. Breeding FOA FHSPA has suffered from lack a throughput phenotyping method inbred breeding approach used development MS lines. We developed an innovative strategy...
Objetivou-se, com este trabalho, identificar indicadores de resistência à toxicidade alumínio em arroz terras altas e linhagens baixa susceptibilidade a esta toxicidade. Avaliaram-se 48 solução nutritiva dois níveis estresse alumínio: 0 40 mg dm-3 Al; após 21 dias teste, estimaram-se massa da matéria seca das raízes do dossel, o comprimento máximo altura plantas e, também, índices alumínio. Verificou-se que todos os ao alumínio, exceto aqueles relacionados variabilidade pH, se...
The study aimed to evaluate the capacity of SSR markers detect gene flow between red rice (RR) and cultivated (CR). is currently used in plant genomic analysis due high information content, be co-dominant, based on PCR reaction. field experiment was organized ten concentric circles, 5 m 50 apart from a central plant, assumed as pollen donor. One hundred twenty CR plants, cv. BR-Irga 409, were planted intersections circles twelve radii. From 51 markers, four selected their polymorphism RR CR,...
