| A bovinocultura de corte, principal atividade economica da sub-regiao da Nhecolandia, do Pantanal, devido, principalmente, a problemas nutricionais, apresenta baixos indices de produtividade. A alimentacao dos bovinos e constituida de pastagens nativas, geralmente de produtividade ou valor nutritivo baixos e de baixa disponiblidade nos meses de cheia. Face a esta situacao, o CPA-Pantanal, entre 1980 e 1985, realizou um experimento de introducao e avaliacao da forrageira em area de "cordilheira" desmatada com o objetivo de identificar gramineas e leguminosas adaptaveis as suas condicoes ecologicas. As forrageiras (43 gramineas e 123 leguminosas) foram plantadas em parcelas de 1,5 x 3,0 m. Foram utilizadas duas parcelas, por local, para cada especie, uma com... |

| Soil organic matter of a humic Oxisol has been characterized by analyzing litter and soil lipid composition under vegetal covers (coffee, pasture and fragment of native forest). Soil and litter samples were collected from each site at two depths (0-10 and 60-100 cm). Lipid composition was determined by gas chromatography-mass spectrometry (CG-MS). In the solvent extracts of the soil lipids, even-numbered n-alkanoic acids in the range of C16-C32 indicate a soil organic matter input from higher plant waxes. The major compound classes in both the soil and the litter included saturated n-alkanoic acids, with average values in the total spectrum of 58 and 53%, respectively Clear differences in lipid composition were found between the topsoil and subsurface.... |

| ABSTRACTThe knowledge regarding of the diaspore and post-seminal development ofPaspalum L. is important for grassland biodiversity conservation, based on their representativeness and genetic improvement of forage. The morphology of the diaspore and the post-seminal development of Paspalum dilatatum Poir. (rhizomatous),P. mandiocanum Trin. var. subaequiglume Barreto (stoloniferous), P. pumilum Nees. (decumbent caespitose) andP. urvillei Steud. (erect caespitose) was described to distinguish species with different growth forms and to survey the characters useful for taxonomy. P. dilatatum differs by presenting oval diaspores larger than the others, with five prominent nerves and trichomes; P. urvillei presents diaspores with one central nerve that is more... |

| Busca alternativas de controle da cigarrinha-das-pastagens, selecionando-se gramineas resistentes a praga em referencia. O experimento foi conduzido de 30 especies de gramineas forrageira distribuidas em blocos ao acaso com 4 repeticoes. As avaliacoes foram feitas atraves de amostragens quinzenais durante o periodo de 1984-86. As gramineas Andropogon gayanus, cv. Planaltina(BRA-000019), Brachiaria brizantha, cv. Marandu (BRA-OOO591), Panicum maximum, cv. Tobiata (BRA-001511), Paspalum secans (BRA-003778) e Paspalum coryphaeum (BRA-003760), mostraram-se resistentes a cigarrinha-das-pastagens. |

| In temperate grasses, fructans are the major storage polysaccharides, being accumulated mainly in mature leaf sheaths, and also in the roots. The partitioning of carbohydrates within different organs regulates plant growth and development. The aim of the present work was to analyze the partitioning of water soluble carbohydrates in five different parts (elongating leaf blades, expanded leaf blades, upper and lower segments of the stubble, and roots) of plants of L. multiflorum cv. Lema, in order to contribute to an understanding of soluble carbohydrates distribution in these plants. Soluble carbohydrates and total fructose were analyzed in plants cultivated during 4 months in a glasshouse, by colorimetric, TLC and HPAEC-PAD techniques. Results showed that... |

| ABSTRACT: The use of intercropped grass legumes provides a source of sustainable animal production as these vegetables contribute to an increase in forage yield by area, and substitute inorganic nitrogen and other components. The objective of this study was to evaluate the nutritional characteristics of silages and the yield and milk quality of Holstein cows fed triticale silages in monoculture or intercropped with either oats or legumes. The crops for silage production were triticale (TS), triticale in consortium with forage pea (TSP), and triticale in consortium with oats, forage peas and vetches (TSOPV). The silages showed no differences in dry matter content. The highest crude protein (13.06 %) and ethereal extract content was observed in TSOPV, but in... |

| ABSTRACT This study presents the description of Phaeosphaeria deschampsii, which was found in plant communities from Half Moon Island, South Shetland Archipelago, Antarctica, in February 2014. Many patches of Deschampsia antarctica (Poaceae), the only indigenous Poaceae specie in Antarctic, were found dead, parasitized by a fungi pathogen. Based on the shape of its perithecia, with oblique neck, erumpent in the grass tissues, ascospore form and septation, the specie was identified as new to science. |
