Crescimento de plântulas de aveia branca submetidas ao estresse salino

The cultivation of white oat in succession to irrigated rice is considered a viable alternative, mainly because of their added value and for their restorative characteristics of the soil, though their productive potential can be reduced considerably because of the soil salinization, being very important to determine salt concentration tolerated by different white oat cultivars.The objective is to evaluate, oat cultivars recommended for the state of Rio Grande do Sul under different salt concentrations in seed germination and early growth. The experimental design was completely randomized factorial 2X5, with four replications, (cultivars Barbarasul and Chiarasul, salt concentration and levels 0, 25, 50, 75 and 100 mM NaCl per liter of water). The physiological seed quality was evaluated in the laboratory by germination, first count of germination, length of shoot and root dry weight of shoot and root. Based on the results we can conclude that: germination and seedling growth of oat cultivars and Barbarasul Chiarasul are negatively affected with increasing salt concentration. In addition the response is more pronounced on the shoot than the root system. The concentration of 100 mM NaCl L-1 impossible to seed germination of both cultivars.

Absorção de cálcio e magnésio por cultivares de aveia submetidas a níveis de toxidez por alumínio

Acid soils with high aluminum (Al) concentrations affect the productivity of oats and many crops. The toxicity of this cation, besides reducing root growth, interferes on the uptake, transport and use of nutrients such as magnesium (Mg) and calcium (Ca). The objective of this work was to evaluate the Ca and Mg uptake ability by measuring their content in the leaf tissues of white oat cultivars. Tolerant and sensitive cultivars were tested under hydroponic culture to verify if the genotypes with greater uptake ability of Ca and Mg do represent those with a tolerant response. In the study, two experiments were performed, one to validate the tolerance groups based on root regrowth and another aiming to reach plant dry masses large enough to determine Ca and Mg. In both situations, the experimental design was completely random at a 3 x 6 factorial for dose and genotype with three replications. The uptake of Ca and Mg are affected by the addition of Al to the hydroponic solution, with tolerant cultivars showing higher concentrations on the leaf tissues than sensitive ones in the absence and presence of Al. Therefore, there is a link between the tolerance levels with the Al uptake, representing a variable to be employed on the selection of more efficient genotypes.

Mycotoxin co-occurrence in rice, oat flakes and wheat noodles used as staple foods in Ecuador

The co-occurrence of aflatoxin B1 (AFB1), B2 (AFB2), G1 (AFG1) and G2 (AFG2), ochratoxin A (OTA), deoxynivalenol (DON), fumonisin B1 (FB1), zearalenone (ZEN), and HT-2 and T-2 toxins in the main Ecuadorian staple cereals (rice, oat flakes, and yellow and white wheat noodles) was evaluated. A ultra high performance liquid chromatography/time-of-flight mass spectrometry (UHPLC/TOFMS) method was developed and validated to screen for the presence of these mycotoxins in those cereal matrices. Matrix-matched calibration curves were used to compensate for ion suppression and extraction losses and the recovery values were in agreement with the minimum requirements of Regulation 401/2006/EC (70–110%). For most mycotoxins, the LODs obtained allowed detection in compliance with the maximum permitted levels set in Regulation EC/2006/1881, with the exception of OTA in all cereals and AFB1 in yellow noodles. Extra target analysis of OTA in oat flakes and wheat noodles was performed by HPLC with fluorescence detection. High rates of contamination were observed in paddy rice (23% DON, 23% FB1, 7% AFB1, 2% AFG1 and 2% AFG2), white wheat noodles (33% DON and 5% OTA) and oat flakes (17% DON, 2% OTA and 2% AFB1), whereas the rates of contamination were lower in polished rice (2% AFG1 and 4% HT-2 toxin) and yellow noodles (5% DON). Low rates of co-occurrence of several mycotoxins were observed only for white wheat noodles (5%) and paddy rice (7%). White noodles were contaminated with DON and/or OTA, while combinations of AFG1, AFB1, DON and FB1 were found in paddy rice. Yellow noodles were contaminated with DON only; oat flakes contained DON, OTA or AFB1, and polished rice was contaminated with AFG1 and HT-2 toxin.

Effects of Two Hypocaloric Diets Supplemented With White Lupine or Oats on Lipid Peroxidation, Reverse Cholesterol Transport and Paraoxonase Activity in Obese Rat

<p>The purpose of this study was to compare the effects of two hypocaloric diets supplemented with legume or cereal on hyperglycemia, dyslipidemia, serum HDL<sub>2</sub> and HDL<sub>3</sub> composition, lipid peroxidation, and lecithin-cholesterol acyltransferase (LCAT) and paraoxonase (PON1) activities in obese rats. Obesity was induced by feeding a high-fat-diet during 3 months. At 400 ± 20 g, the obese rats were divided into three groups (n = 8): two groups were submitted for 28 days to a caloric restriction (CR) at 0.9 MJ supplemented with lupine (CR–Lupine group) or oats (CR–Oats group). The third group was fed a caloric restricted diet without supplementation (CR group). At day 28, glycemia was lower (-21%) in the CR–Oats than the CR group. CR–Oats diet reduced total cholesterol content (-13%) when compared to lupine supplementation. In contrast, CR–Lupine diet decreased serum triacylglycerols by 22% and 15% respectively <em>versus</em> CR–Oats and CR diets. Lipoproteins lipid peroxidation was significantly lower in CR–Lupine and CR–Oats when compared to the CR diet. Serum PON1 activity was increased in CR–Lupine (+88%) and CR–Oats (+82%) groups compared to CR group. Furthermore, LCAT activity was enhanced in CR– Lupine (+23% and +26%, respectively) <em>versus</em> CR and CR–Oats groups. In obese rats, caloric restriction supplemented with lupine compared to oats supplementation has beneficial effect on hypertriglyceridemia and improves reverse cholesterol transport by enhancing LCAT activity leading to anti–atherogenic effects. This effect is partially reinforced by the high HDL PON1 activity which protects it from oxidation.</p>

Dinâmica de produção de forragem de gramíneas anuais de inverno em diferentes épocas de semeadura

A determinação da produção de cada planta forrageira, em cada período, ao longo de sua estação de crescimento, é importante para que se possa orientar o planejamento forrageiro. Objetivou-se com este trabalho avaliar a taxa de acúmulo de matéria seca em diferentes forragens de estação fria em épocas de semeadura distintas. O trabalho foi realizado no período de março a novembro de 2009 para avaliar a taxa de acúmulo diária de forragem em forrageiras anuais de inverno (diferentes cultivares (cvs) de aveia, azevém, centeio, trigo e triticale) em quatro épocas de semeadura (11/3, 8/4, 6/5 e 3/6). As produções de forragem foram convertidas em taxas diárias de acúmulo. Verificou-se interação entre as taxas de acúmulo de forrageiras e épocas de semeadura para todos os caracteres avaliados, indicando flexibilidade no planejamento de implantação das forrageiras. As culturas que tiveram destaque foram as aveias brancas, cvs 'UTF Iguaçú' e 'IPR 126', a aveia preta, cv 'IAPAR 61', as cultivares de azevém e centeio, que apresentaram, em média, produção diária de forragem de 51,4kg ha-1 após a primeira utilização, demonstrando possuírem elevada capacidade de produção e manutenção da produção, especialmente se semeadas até início de maio.

Produção de forrageiras anuais de inverno em diferentes épocas de semeadura

O trabalho foi realizado com o objetivo de avaliar as características produtivas de forrageiras anuais de inverno (Avena strigosa Schereb, Lolium multiflorum Lam, Avena sativa, Triticum aestivum, Secale cereale e Triticosecale Wittmack) em quatro épocas de semeadura (11/3; 08/4; 06/5 e 03/6 de 2009). Foram avaliados o número de dias para o primeiro corte, o número de cortes, dias de utilização da pastagem, a densidade de plantas e perfilhos, a produção total, a matéria seca residual e a produção por corte. Houve interação significativa entre forrageiras e épocas de semeadura para todas as variáveis analisadas, o que possibilita alterar o planejamento forrageiro combinando cada forrageira dentro da melhor época de semeadura, direcionando a produção de forragem com o objetivo de suprir os vazios forrageiros. Uma das opções é a semeadura de aveia preta no início de março suprindo mais convenientemente as forragens no outono aos animais, em relação à sua semeadura em abril, mesmo que esta apresentasse uma produção total de forragem maior. Porém, se a maior necessidade de forragem é na primavera, a melhor combinação seria azevém semeado em junho. As aveias brancas, os azevéns, e a aveia preta IAPAR 61, são materiais com alta capacidade de produção e distribuição de forragem, especialmente se semeadas até início de maio.

Pyricularia blast on white oats: a new threat to wheat cultivation

A newly emerged disease, the Pyricularia blast caused by Pyricularia grisea, is commonly observed on wheat and black oats, since its discovery in 1985. Within a few years the disease spread to other species of Gramineae, but white oat cultivars remained resistant and were the only ones among cultivated cereals resistant to this disease. In 2012, one commercial field of white oat cultivar IAC 7 was found severely attacked by Pyricularia blast in Assis, in the state of Sao Paulo. The objective of the present investigation was to find out whether other white oat cultivars are also susceptible to the new P. grisea isolate from cv. IAC 7 and to determine the pathogenic variability, if any, among P. grisea isolates from black oats. Thirty-three white oat cultivars, along with some cultivars of black oat, barley, wheat, triticale, and rye were evaluated against the IAC 7 isolate. Results of disease severity analysis indicated that four white oat cultivars were resistant, seven were moderately resistant and the remaining were susceptible or highly susceptible. Five wheat cultivars were also resistant. Pathogenic variation among P. grisea isolates from black oats was observed.

Genetic Diversity and Population Structure Among Oat Cultivars and Landraces

In this study, genetic diversity among 177 oat (Avena sativa L.) accessions including both white and red oat landraces and 36 commercial cultivars was studied for simple sequence repeat (SSR) loci. Thirty-one genomic and expressed sequence tags (EST)-derived primer pairs were selected according to high polymorphism from an initial 66 SSR batch. Markers revealed a high level of polymorphism, detecting a total of 454 alleles. The average gene diversity for the whole sample was 0.29. Genetic similarity, calculated using the Dice coefficient, was used for cluster analysis, and principal component analysis was also applied. In addition, population structure using a Bayesian clustering approach identified discrete subpopulation based on allele frequency and showed similar clustering of oat genotypes in four groups. Accessions could be classified into four main clusters that clearly separated the commercial cultivars, the red oat landraces and two clusters of white oat landraces. Cultivars showed less diversity than the landraces indicating a reduction of genetic diversity during breeding, whereas white oat landraces showed higher diversity than red ones. The average polymorphic information content of 0.80 for the SSR loci indicated the usefulness of many of the SSR for genotype identification. In particular, two markers, MAMA5 and AM04, with a total of 50 alleles and a high discrimination power (>0.90), were sufficient to discriminate among all commercial cultivars studied highlighting their potential use for variety identification.

This work aimed to assess the yield of five forage species subjected to nitrogen (N) levels at three different cutting ages. The experiment was carried out in the city of Santa Tereza do Oeste, at IAPAR’s (Agronomic Institute of Paraná) experimental field, by applying a randomized complete block design in a factorial scheme 5×4×3, with five species: common black oat (Avena strigosa Schreb cv. Common), IPR 61 oat (Avena strigosa Schreb cv. IPR 61), Triticale Tpolo 981(Xtriticosecale wittmack), IPR 126 White oat (Avena sativa cv. IPR 126) and ryegrass (Lolium multiflorum Lam.); N levels were (0, 30, 60 and 120 kg ha-1); cutting ages were 66, 95 and 116 days after emergence (DAE), with three replications. Dry matter (DM) productivity was assessed in kg ha-1 by cut and total. The common black oat proved to be different from the other forage plants in DM yield, accumulating less quantities of it due to its cycle. The application of nitrogen fertilization to the coverage linearly influenced the ryegrass at 66 DAE and all other species at 116 DAE in a positive manner. Nitrogen did not influence the total accumulation of dry matter of both common black oat and Triticale Tpolo 981.  Key words: Avena sativa L., Triticosecale wittmack, Lolium multiflorum Lam, nitrogen, cuts.

Rendimento de grãos de soja em diferentes sistemas de produção integração lavoura-pecuária

In Brazil, there are relatively few papers about soybean crop in succession of pasture to steer performance. This work aimed to study changes in yield and yield components of soybean in succession in crop-livestock production systems, under no-tillage, were assessed in Coxilha, State of Rio Grande do Sul, Brazil, during ten years. Six crop-livestock production systems were studied: system I - wheat/soybean, and common vetch/corn; system II - wheat/soybean, and black oat pasture/corn; system III - wheat/soybean, and black oat pasture/soybean; system IV - wheat/soybean, and field pea/corn; system V - wheat/soybean, common vetch/soybean, and triticale double purpose/soybean; and system VI - wheat/soybean, white oat double purpose/soybean, and double wheat purpose/soybean. The treatments were arranged in a completely randomized block design, with four replications. In the year, no differences were found between grain yields, weight of 1,000 kernels, plant height and insertion first legumes height of soybean in crop-livestock production systems. The soybean cultivated in succession after common vetch showed higher number of pods, number of grains and weight of grain per plant than the other crop systems.

Critérios de calagem e teores críticos de fósforo e potássio em latossolos sob plantio direto no centro-sul do Paraná

A adoção do plantio direto (PD) em substituição ao preparo convencional promove alterações na dinâmica de nutrientes e na acidez no solo, podendo influenciar as relações solo-planta e, portanto, os critérios de manejo da fertilidade do solo. Este estudo teve como objetivo determinar os critérios de recomendação de calagem e os teores críticos de fósforo (P) e potássio (K) para o sistema de rotação de culturas envolvendo soja, milho, trigo, cevada e aveia branca, amplamente adotado na região Centro-Sul do Paraná. O estudo foi com base em 13 experimentos de campo conduzidos em Latossolos Brunos em longo prazo em PD (>15 anos), nos municípios de Guarapuava, Pinhão e Candói. Desses, cinco envolveram calagem e oito adubação de P e K. Em amostras de solo das camadas de 0-0,10 e 0,10-0,20 m, foi determinado o pH (CaCl2) e calculada a saturação por bases (V%) nos experimentos de calagem e os teores de P e K disponível (Mehlich-1) nos experimentos de adubação. O método dos quadrantes foi utilizado para determinar os critérios de recomendação de calagem; e o nível crítico de pH e V% consistiu no valor em que, acima do qual, as culturas apresentaram rendimento relativo (RR) superior a 90 % e nunca inferior a 80 %. A relação entre os teores de P e K e os valores de RR foi verificada pela equação de Mitscherlich, sendo o teor crítico aquele correspondente ao RR de 90 %. Os resultados indicaram que os níveis críticos relacionados à acidez e disponibilidade de P e K foram maiores para a camada de 0-0,10 m do que para a de 0-0,20 m. A cultura da soja foi mais sensível à acidez do solo, enquanto os cereais de inverno foram mais exigentes em P e K. Tomando-se como referência as culturas mais restritivas do sistema de rotação e a camada de 0-0,20 m, os níveis críticos para calagem foram pH (CaCl2) de 4,9 e saturação por bases de 60 %, enquanto os teores críticos para adubação foram 8 mg dm-3 de P e 0,30 cmol c dm-3 de K para Latossolos cultivados no longo prazo em sistema PD na região Centro-Sul do Paraná.

Combinação entre turfa vermelha e areia na obtenção de substrato-inóculo do fungo micorrízico arbuscular Glomus clarum

O objetivo com o presente estudo foi verificar a influência de diferentes proporções de turfa vermelha e areia na composição do substrato sobre a colonização radicular por fungos micorríozicos arbusculares (FMA) e no desenvolvimento vegetativo de aveia branca. O experimento foi conduzido em casa de vegetação e os tratamentos foram constituídos a partir de combinações de turfa vermelha (T) e areia (A): 100%A; 25%T+75%A; 50%T+50%A; 75%T+25%A; 100%T. Dez sementes de aveia foram semeadas por vaso plástico preto (350ml de volume), contendo 5 gramas de inóculo de Glomus clarum. Quarenta e três dias após a semeadura da aveia, foram realizadas avaliações de desenvolvimento vegetativo e colonização micorrízica do sistema radicular das plantas, através da presença de estruturas, como hifas, arbúsculos e vesículas. Substratos com maior quantidade de turfa induziram maior desenvolvimento da parte aérea e maior qualidade de raízes (QR), em termos de volume de raízes. Entretanto, a presença da turfa acima de 50% no substrato diminuiu a percentagem de colonização micorrízica da aveia. A similaridade verificada entre as curvas de regressões de percentagem de colonização e Água Facilmente Disponível, com mesmo ponto de máximo, sugerem que a quantidade de mesoporos resultante da combinação turfa/areia influencia na resposta dos FMA, a melhor resposta é obtida em mistura com 32,5% de turfa vermelha.

Effects of superficial liming and silicate application on soil fertility and crop yield under rotation

Soil acidity and low natural fertility are the main problems for grain production in Brazilian ‘cerrado’. Although lime has been the most applied source for soil correction, silicate may be an alternative material due to its lower solubility and Si supply, which is beneficial to several crops. This work aimed to evaluate the efficiency of superficial liming and calcium/magnesium silicate application on soil chemical attributes, plant nutrition, yield components and final yield of a soybean/white oat/maize/bean rotation under no-tillage system in a dry-winter region. The experiment was conducted under no tillage system in a deep acid clayey Rhodic Hapludox, Botucatu-SP, Brazil. The design was the completely randomized block with sixteen replications. Treatments consisted of two sources for soil acidity correction (dolomitic lime: ECC=90%, CaO=36% and MgO=12%; calcium/magnesium silicate: ECC=80%, CaO=34%, MgO=10% and SiO2=22%) applied in October 2006 to raise base saturation up to 70% and a control, with no soil correction. Soybean and white oat were sown in 2006/2007 as the main crop and off-season, respectively. Maize and bean were cropped in the next year (2007/2008). Products from silicate dissociation reach deeper soil layers after 18months from the application, compared to liming. Additionally, silicate is more efficient than lime to increasing phosphorus availability and reducing toxic aluminum. Such benefits in soil chemical attributes were only evidenced during bean cropping, when grain yield was higher after silicate application comparatively to liming. Both correction sources were improved mineral nutrition of all the other crops, mainly Ca and Mg levels and agronomical characteristics, reflecting in higher yield.

Desempenho de genótipos de aveia branca em resposta ao estresse por alumínio

A aveia branca (Avena sativa L.) é uma cultura que tem um papel importante no sistema de produção de grãos e integração lavoura-pecuária, no entanto, em algumas regiões brasileiras, o pleno estabelecimento e desenvolvimento dessa cultura, bem como o aumento de produtividade são inviabilizados pelo excesso de alumínio (Al) nos solos. A avaliação de caracteres de plântulas de aveia desenvolvidas sob cultivo hidropônico com adoção de solução nutritiva mínima pode ser eficiente para classificar genótipos sensíveis e tolerantes ao Al. Este trabalho objetivou avaliar o desempenho de 10 genótipos de aveia submetidos ao estresse por Al, baseando-se na análise da retomada do crescimento da raiz, com uso de solução mínima e identificando quais caracteres se mantêm correlacionados. Foram adotadas diferentes doses de Al (0, 3, 6, e 9 mg L-1 de Al). Com uso de solução mínima, a dose de 6 mg L-1 de Al é a mais adequada na diferenciação de genótipos sensíveis e tolerantes. Dentre os genótipos estudados, UFRGS 14, UFRGS 19 e URS Guapa são os mais tolerantes e UPFA 20, UPF 18 e IAC 7, os mais sensíveis ao Al. Com o objetivo de classificar genótipos de aveia entre sensíveis e tolerantes ao Al, nenhuma outra variável pode ser utilizada em substituição à retomada do crescimento da raiz.

Wpływ sposobu uprawy gleby, przedplonu i rodzaju pozostawionej biomasy na porażenie jęczmienia jarego przez grzyby chorobotwórcze

Summary Field experiment was conducted in the years 2007–2009 at the Research and Education Center Gorzyn branch Swadzim Poznan University of Life Sciences. The aim of this study was to determine the severity of infection by patogenic fungi on spring barley as an effect by different tillage systems (conventional and direct drilling), forecrop (beet and maize) and kind of crop residue (white mustard, oats, spring vetch, wheat straw and wheat stubble).

Parameters of adaptability and stability in brazilian and exotic cultivars of white oat

The introduction of exotic germoplasm is one of the most important tools in obtaining genetic variability in breeding programs. However, it presents problems of adaptation and stability on specific conditions of climate and soil. The objective of the study was to evaluate the performance of Brazilian and exotic genotypes of oat (Avena sativa L.) and the parameters of adaptability and stability in different years of cultivation to local conditions in Capao do Leao/RS, Brazil. Experiments were conducted in 2005, 2006 and 2007 using ten US oat cultivars, thirteen brazilian cultivars and one canadian cultivar, in an experimental design of randomized blocks with three replications. The national usually outperformed the foreign genotypes, the latter showing difficulties in adaptation to the studied conditions. Cultivars Assiniboia and Hi-Fi had performances similar to the Brazilian elite genotypes, with adequate average production, good adaptability and phenotypic stability. The introduction of this type of germplasm may increase the gene pool with new groups of genes and/or alleles carrying genetic gains in the improvement of oats.

Adaptability and stability of white oat cultivars in relation to chemical composition of the caryopsis

The objective of this work was to characterize the chemical properties of white oat (Avena sativa) caryopsis and to determine the adaptability and stability of cultivars recommended for cultivation in the state of Rio Grande do Sul, Brazil. The trials were carried out in the 2007, 2008 and 2009 crop seasons, in three municipalities: Augusto Pestana, Capão do Leão, and Passo Fundo. Fifteen cultivars were evaluated in a randomized block design, with four replicates. The contents of protein, lipid, and nitrogen-free extract were evaluated in the caryopsis. Cultivar performances for the measured characters varied according to location and year of cultivation. The cultivar URS Guapa showed high content of nitrogen-free extract and low contents of protein and lipid in the caryopsis. 'FAPA Louise' showed high content of lipid, whereas 'Albasul', 'UPF 15', and 'UPF 18' showed high content of protein and low content of nitrogen-free extract. There is no evidence of an ideal biotype for the evaluated characters, which could simultaneously show high average performance, adaptability to favorable and unfavorable environments, and stability.

Biomass production, weed suppression, nitrogen and phosphorus uptake in white oat (Avena sativa L.) and grazing vetch (Vicia dasycarpa L.) cover crop bicultures under an irrigated no-till system

Cultivation of a multipurpose cover crop is of interest to Eastern Cape farmers experiencing soil infertility and weed pressures. The objective of the study was to investigate effects of oat–vetch bicultures on biomass production, weed suppression, and nitrogen (N) and phosphorus (P) uptake. The study was conducted between 2009 and 2010. Treatments included 90% oat + 10% vetch, 70% oat + 30% vetch, 50% oat + 50% vetch, 100% vetch, 100% oat and a weedy fallow as control. Bicultured cover crops had significantly (p < 0.05) higher biomass compared to sole vetch in both seasons but reduced biomass compared to sole oat only in 2010. Weed suppression increased with an increase in biomass. Weedy fallow had the least weed suppression (p < 0.05) at all sampling times, whereas sole oat provided the best early weed control compared to the rest of treatments. Nitrogen uptake by sole vetch was comparable to 50% oat + 50% vetch and 70% oat + 30% vetch. Phosphorus uptake differed only in the 2010 season and 90% oat + 10% vetch, 70% oat + 30% vetch and sole vetch had the best uptake. Weedy fallow had the least N and P uptake during the two seasons. Bicultures can be used for improved biomass, weed suppression, and N and P uptake with potential of alleviating soil degradation effects in the Eastern Cape province.

FAEM Chiarasul: new white oat cultivar with high yield and grain-processing quality

The white oat cultivar FAEM Chiarasul was developed from a cross between UFRGS 17 and UFGS 10/ Coronado2/Cortez3/Pendek/ME 1563. It is characterized by reduced plant height, and high yield, grain quality and grain-processing quality.
