Full textThe alfalfa (Medicago sativa L.) is a legume that has many relevant characteristics such as high yield potential and forage quality and flexibility of use, and that when properly managed, a culture able to provide quality forage and promote an increase in the quality of herds. For the further expansion of this forage in Brazil, it is necessary to overcome certain obstacles such as lack of cultivars adapted to our climate and soil conditions, low soil fertility and inadequate management. Genetic improvement of alfalfa for tolerance to acid soils and suitability to grazing can be an important alternative for the development and establishment of this culture, contributing to the production of meat and milk in the country. The present study aims at the early selection of alfalfa genotypes for tolerance to aluminum (Al) and to grazing aptitude. For this, two experiments were conducted. In the experiment for selecting plants for Al tolerance were evaluated nine genotypes (Crioula as witness, ECF1, Soil, and Solution Erechim, POA, Estrela and SJI) in a nutrient solution containing different concentrations of Al (0.0, 3.0 , 6.0, 12, 24, 48 μMol / L AlCl3). Root length was measured, and selected twenty-five seedlings that had the greatest root length. There was one more cycle of selection and the results showed the superiority of root growth of populations SJI, Solution, and POA, indicating a higher tolerance to Al toxicity. In the experiment to select for grazing aptitude, were assessed eight genotypes (ABT as a check, Erechim, POA, SJI, Star, and the populations already on the Plant Breeding Program for grazing aptitude, UFRGS, (E1C2, E1C3, E2C2 and E2C3 ). The morphological markers used were the length of 1st and 2nd internode (cm). Were selected 25 seedlings from each population, which had the shortest length of 1st and 2nd internode, totaling fifty plants. The genotype SJI and the populations that already participate in the Plant Breeding Program behaved very similar to the witness (ABT), showing that have a higher grazing aptitude. In addition, the morphological marker of the 1st internode length was more efficient in the selection of genotypes for grazing aptitude. Therefore, the results showed that it is possible to make progress for grazing aptitude as well as for Al tolerance.

Experiments investigating the characteristics of forage legume were carried out in 2007 and 2008 at the Experimental Station in Itambe and São Bento do Una, both belonging to the State of Pernambuco Institute Agricultural Research Corporation, Brazil (IPA). The first experiment set out to characterize the morphology and quality of three plantations, each containing legumes comprising Mimosa caesalpinifolia Benth. (Sabiá) and Machaerium aculeatum Raddi (Espinheiro) in Itambe, and Bauhinia cheilantha (Bong.) Steud. (Mororó) in São Bento do Una. Simple description techniques were used, as well as more complex ones, such as path correlation and analysis. At the end of the morphological evaluation, specimens of leaves and stalks were collected (< 4mm) to determine the chemical composition and digestibility in vitro of the dry matter. The second experiment took place in 2008 in the town of Itambé-PE, with the intention of characterizing the Sabiá, Mororó e leucena legumes which were two years old at the start of the experiment. Uniform cutting was carried out, and every seventy days the production of dry matter, morphology and chemical composition were determined. At the end of the evaluations, leaves were collected to determine the degradability in situ and the folic anatomy. The majority of variables correlated positively with the in vitro digestibility of the dry matter of the three species evaluated. Sabiá, Mororó and Espinheiro proved to be very heterogeneous in relation to their morphological variables. The legumes presented high levels of dry material, crude protein, and fibre in neutral detergent, fibre in acidic detergent and digestibility of dry matter in vitro. With path analysis it was observed that the crude protein variable was responsible for the in vitro increase in digestibility of the dry matter. It was observed that, for morphological and productive characteristics, the species differed among each other and among evaluation periods, resulting in values between 1.4 and 4.4 t of MS/ha/cutting: 1.44 to 2.76m in height; 6.6 to 25.2 leaves/branch; 0.95 to 1.51m in the diameter of the crown and 24.9 to 43.3cms in diameter at the base of the trunk. Leaf cross sections of Sabiá revealed highly lignificated materials which differed from those of the Leucena and Mororó. There was a greater degradation in the leaves of Leucena, Sabiá and Mororó respectively. The legumes presented high levels of crude protein and low levels of digestibility in vitro of dry matter. In relation to the production of dry matter, there was a low correlation between almost all the explicative variables and the principal variable in the legumes studied. However, the height and crown diameter (Leucena), number of leaves and crown diameter (Mororó) and height and crown diameter (Sabiá) better explain the production potential of dry matter which interferes directly or indirectly with the dependent variable. This indicates that those who wish to select plants with high production of dry matter should select characteristics such as height, crown diameter and number of leaves.
Foram conduzidos dois experimentos de caracterização de leguminosas forrageiras, durante os anos de 2007 e 2008, na Estação Experimental de Itambé e São Bento do Una, pertencentes ao Instituto Agronômico de Pernambuco – IPA. O primeiro experimento objetivou caracterizar a morfologia e qualidade de três bosques de leguminosas com 30 plantas cada, encontrando-se as plantas de Mimosa caesalpinifolia Benth. (Sabiá) e Machaerium aculeatum Raddi (Espinheiro) no município de Itambé e as plantas de Bauhinia cheilantha (Bong.) Steud. (Mororó) no município de São Bento do Una. Utilizou-se técnicas simples de descrição e também mais elaboradas como a correlação e análise de trilha. Após o termino das avaliações morfológicas foram coletadas amostras de folhas e caules (< 4 mm) para determinação da composição química e digestibilidade in vitro da matéria seca. O segundo experimento ocorreu no ano de 2008, no município de Itambé-PE, com o objetivo de caracterizar as leguminosas Sabiá, Mororó e Leucena, aos dois anos de idade, no início do experimento, sendo realizado corte de uniformização e a cada 70 dias determinada a produção de matéria seca, morfologia e composição química. Após o término das avaliações foram coletadas folhas para determinação da degradabilidade in situ e anatomia foliar. A maioria das variáveis correlacionou-se positivamente com a digestibilidade in vitro da matéria seca nas três espécies avaliadas. As leguminosas Sabiá, Mororó e Espinheiro se mostraram bem heterogêneas em relação a suas variáveis morfológicas. As leguminosas apresentaram altos teores de matéria seca, proteína bruta, fibra em detergente neutro, fibra em detergente ácido, proteína insolúvel em detergente ácido e digestibilidade in vitro da matéria seca. Com a análise de trilha observou-se que, a variável proteína bruta foi responsável pelo aumento da digestibilidade in vitro da matéria seca. Observou-se que, para caracterização morfológica e produtiva, as espécies diferiram entre si e entre períodos de avaliação, apresentando valores entre 1,4 a 4,4 t de MS/ha/corte; 1,44 a 2,76m de altura; 6,6 a 25,2 números de folhas/ramos; 0,95 a 1,51m de diâmetro da copa e 24,9 a 43,3 cm de diâmetro da base do caule. Foram observados na lâmina foliar das plantas de Sabiá, tecidos bastante lignificados que diferiram das plantas de Leucena e Mororó. Ocorreu maior degradação nas folhas de Leucena, Sabiá e Mororó, respectivamente. As leguminosas apresentaram altos teores de proteína bruta e baixos valores de digestibilidade “in vitro” da matéria seca. Em relação à produção de matéria seca, houve baixa correlação entre quase todas as variáveis explicativas e a variável principal nas leguminosas estudadas. Entretanto, as características altura da planta e diâmetro da copa (Leucena), número de folhas e diâmetro da copa (Mororó) e altura da planta e diâmetro da copa (Sabiá) explicaram melhor o potencial de produção de matéria seca, que interferiu de forma direta e indireta sobre a variável dependente, indicando que para o melhorista que deseja selecionar plantas com altas produções de matéria seca, deve selecionar características como altura da planta, diâmetro da copa e número de folhas.

Full textThe flowering dynamics, seed yield components, and the seed production of Lotus subbiflorus cv. El Rincón were evaluated. This study was conducted at the Agronomical Experimental Station of the Federal University of Rio Grande do Sul (AES/UFRGS), located in Eldorado do Sul, city of RS, physiographic region named Central Depression. Two experiments were conducted, the first in 2007/2008 and the second, in 2008/2009. In both years, the seeds obtained from Uruguay were inoculated and broadcast sowed on 01/06/2007, and sowed in rows, on 25/04/2008. The weekly samplings were carried out with 25 x 50 cm rectangles, randomly disposed over the experimental area, in a completely randomized experimental design and in randomized blocks, in the first and second year, respectively. The following variables were analyzed: number of floral buds/m², number of infloresensces/m², number of flowers/m², number of total legumes/m², number of mature legumes/m², number of seeds/m², weight of 1000 seeds, seed yield/m², weight of dry matter of herbage and harvest index. The flowering of L. subbiflorus in the region where the experiment was conducted initiated in November, with the most intense flowering taking place between the end of December and beginning of January. The most important seed yield components, in both years, were the number of mature legumes/m² and the number of seeds/m², and the most appropriate time for seed harvest was at approximately 4.000GD, counted since the sowing date. The best time for legumes harvest was in January, with the maximum obtained seed yield of 54 kg/ha, in the second year. In the first year, the yields were very low, mainly due to the presence of weed species.

A produção de volumosos para a alimentação animal através do sistema de integração lavoura-pecuária é uma alternativa para a recuperação de pastagens degradadas e para a produção de volumosos conservados de alta qualidade. Neste sistema, o consorcio de gramíneas com leguminosas pode ser uma estratégia para a produção de silagem, pois a fixação biológica de nitrogênio incrementa os teores e a disponibilidade desse nutriente no solo, consequentemente, melhorando o valor nutricional da silagem. Pesquisas em busca de alternativas para volumosos de melhor qualidade são fundamentais para a eficiência dos sistemas de produção de cordeiros, principalmente para o confinamento, pois a alimentação representa o maior custo neste sistema. O presente trabalho teve o objetivo de avaliar o efeito de volumosos, provindo de um sistema de integração lavoura-pecuária, sobre o desempenho, digestibilidade, produção de metano e dióxido de carbono entérico, comportamento ingestivo e a análise de custos da terminação de cordeiros ½ Dorper e ½ Santa Inês em confinamento, com dietas contendo concentrado e diferentes silagens (silagem de milho exclusivo, silagem de milho + Urochloa brizantha cv. Marandu e silagem de milho + Urochloa brizantha cv. Marandu + guandu-anão). O ganho médio diário (kg/dia), assim como o período em que os cordeiros permaneceram confinados, não foi influenciado pelas diferentes dietas. A utilização da silagem proveniente do consórcio do milho, Marandu e guandu-anão na dieta de cordeiros, proporcionou aumento no consumo de matéria seca (kg/dia) e acresceram os tempos dispendidos para ruminação, mastigação e distribuição da fibra fisicamente efetiva. As dietas mostraram rentabilidade favorável na terminação de cordeiros em confinamento; entretanto, o maior retorno econômico foi obtido com o sistema em que os animais foram alimentados com silagem de milho exclusivo. A dieta contendo silagem de milho em consórcio com Marandu e guandu-anão proporcionou aumento do consumo de proteína bruta (kg/dia) quando comparada a silagem de milho (0,273 e 0,238, respectivamente). O potencial de produção de gases de efeito estufa, foi inferior para as dietas contendo as silagens de milho em consórcio, principalmente no consórcio de milho com Marandu e guandu-anão, que reduziu a emissão de metano e dióxido de carbono em 37,86 e 28,05%, respectivamente. A utilização de animais capazes de apresentar melhores ganhos diários de peso vivo, em confinamento, aliado ao sistema de integração lavoura-pecuária, pode ser eficiente economicamente e ambientalmente, diminuindo a taxa de emissão de metano. Os consórcios do milho com Marandu e/ou guandu-anão forneceu alimento de qualidade, melhorando a digestão fermentativa do rúmen de cordeiros em confinamento. A intensificação da produção de carne pode diminuir a produção de metano por quilo de carne produzida.
The production of forage to the feeding through the integrated crop-livestock system (ILP) is an alternative for the recovery of degraded pastures and the production of silage high quality. The consortium of grasses with legumes can be a strategy for the production of silage because the biological nitrogen fixation increases the levels and the availability of this nutrient in the soil, thus improving the nutritional value of the silage. Research in search of alternatives to bulky best quality are fundamental to the efficiency of sheep production systems, primarily for the confinement because food represents the largest cost in this system. The aimed of this study was to evaluate the effect of silage, coming from a crop-livestock integration system on performance, digestibility, production of CH4 and CO2 in vitro, feeding behavior and cost analysis termination lambs ½ Dorper ½ Santa Inês in feedlot, with diets consist of concentrated and different silages (corn silage; corn silage + Urochloa brizantha cv. Marandu and corn silage + Urochloa brizantha cv. Marandu + pigeon pea). Average daily gain (kg/day) and the period during which the lambs were confined, was not influenced by the different diets. The use of silage from corn consortium with Marandu and pigeon pea in the diet of lambs led to an increase in dry matter intake (kg/day) and further compounded the times spent for ruminating, chewing and distribution of physically effective fiber. Diets showed favorable profitability in finishing lambs in confinement; however, the greatest economic return was obtained with the system in which the animals were fed with silage corn. The diet containing corn silage in consortium with Marandu and pigeon pea provided increased crude protein intake (kg/day) compared to corn silage (0,273 and 0,238, respectively). The potential production of greenhouse gases, was lower for diets containing corn silage in consortium, especially in maize intercropped with Marandu and pigeon pea which reduced the emission of methane and carbon dioxide in 37,86 and 28,05%, respectively. The use of animals able to present best daily gains of live weight in confinement, coupled with crop-livestock integration system can be economically and environmentally efficient, reducing methane emission rate. Consortia of corn with Marandu and/or pigeon pea provided quality food, improving the fermentative digestion from the rumen of lambs in confinement. The intensification of beef production may decrease methane production per kilogram of meat produced.

Full textRed clover is one of the most utilized leguminous forage species in the world agriculture being adapted to a great number of edaphic-climatic conditions. The objective of this work was to evaluate the genetic diversity in the core collection of red clover using morphologic, molecular and biochemical traits. The accessions of red clover from the core collection of NPGS-USDA were analyzed with 21 morphological characters, 14 microsatellite loci (SSR), with 114 RAPD markers and with 15 loci of isozyme (esterase) markers. The molecular markers, used for the first time in the core collection, together with the morphological and biochemical markers pointed out for the high genetic diversity present in the species, mostly at the intrapopulational level. The cluster analysis of the morphological data revealed five distinct clusters that separated early, medium and wild blooming types as well as groups with more persistence and high dry matter production in the Southern Brazilian conditions. A total of 78 fragments (SSR) were scored and the PIC ranged from 0.70 to 0.91 with 0.86 as mean value. The mean Rogers’ genetic distance based on the 78 SSR markers was 0.49. The Jaccard’s similarity based on 114 RAPD markers was 0.21 and allowed the identification of all accessions. The mean expected heterozygosity (He), based on isozyme data, was He = 0.238 and the mean Rogers’ genetic distance was 0.14. Isozyme data clustered the accessions of red clover in four groups. The clusters found with morphological and biochemical markers were not separated according to their geographic origin or type of populations (cultivar, wild or landrace). However, some coincidences between analyses were found once cultivars from north Europe were clustered in both types of analyze. The results found here evidenced the high and complex diversity in red clover core collection. Indeed, they highlighted some promising populations that could be used in the Brazilian breeding programs of red clover.

Full textWhite clover (Trifolium repens L.) it is one of the most important forage legumes in temperate regions of the world, being one of the most used species in pastures during the winter and spring in Rio Grande do Sul, which has persistence problems, mainly in the summer, due to the high temperatures and the low water availability in that period. The work was aimed to analyze the genetic diversity among the accessions from the white clover core collection obtained from the United States Department of Agriculture (USDA) through isozymes and microsatellite markers, besides evaluating the effect of water availability (90 and 50% of the soil moisture field capacity) on morphophysiological traits of a sample of the collection. The accessions were analyzed through 18 isozyme bands (esterase) and nine microsatellites loci (SSR), which were efficient to detect the high existent genetic diversity among the accessions. A total of 70 SSR fragments was analyzed, obtaining an average of 7,8 alleles per locus and, a PIC varying from 0,26 to 0,86, with average of 0,67. The medium genetic distance through Nei's coefficient for the esterase data was 0,73, varying from 0 to 1,79, evidencing five groups formed for the 47 analyzed accessions, while for SSR the medium distance was 0,68, varying from 0,18 to 2,25, classifying the 81 accessions in seven groups. In relation to drought tolerance, there was interaction genotype x level of water for 12 of the 23 measured variables in the first evaluation, and 19 of the 32 variables analyzed in the second. The best accessions under water deficit were 75 and 74, which triplicate and double, respectively, the water use efficiency, showing larger internodes length and consequently larger productions of MSPA. Therefore this work represents a contribution to the study of the genetic variability and to the characterization of the accessions of the core collection of the specie, through biochemical and molecular markers, as well as through morphophysiological markers under water stress conditions.

Full textWhite clover is a legume forage most widely used in pastures during the winter and spring in the RS, but nevertheless may have persistence problems, especially in summer. The aim of this work was to select higher forage yield and tolerance to low water availability genotypes, evaluating agronomically their progeny and characterizing them morphologically and genetically with the aid of SSR molecular markers. The agronomic evaluation was performed at the EEA / UFRGS, in Eldorado do Sul and Embrapa CPPSUL in the city of Bage. Was evaluated the DM yield of 22 progenies and the two white clover cultivars UFRGS and Jacuí, intercropped with ryegrass (Lolium multiflorum Lam.), during the years 2008 and 2009. The progenies were characterized using nine morphological markers in twenty plants of each treatment. The mother plants and progenies were genetically characterized using five SSR primers. The average DM yield of white clover during the two years was 3671 and 2107 kg / ha, in Eldorado do Sul and Bage, respectively. Statistical analysis separated the treatments into two groups in both locations by Scott & Knott (P <0.05) test. In Eldorado do Sul and Bage the cultivar Jacuí more thirteen progenies formed groups with higher production. Seven progeny were in the group "a" in both places, while only the cultivar UFRGS and one progenie had lower production in the two sites, there genotype-environment interaction. The group of morphological traits used to allow a good characterization of genotypes, with most of the progenies presenting at least one morphological difference compared to commercial cultivars. There is genetic variability in the germplasm analyzed for the morphological and molecular characteristics. This work verified that it is possible to select genotypes more productive and more resistant to summer conditions, optimizing the use of this specie.
