RESUMOConduziu-se, o presente trabalho, no Laboratório Didático de Análise de Sementes da Universidade para o Desenvolvimento do Estado e da Região do Pantanal -UNIDERP, com o objetivo de avaliar a qualidade física e fisiológica de sementes de três espécies de braquiárias (Brachiaria brizantha, B. humidicola e B. decumbens), provenientes de seis empresas estabelecidas no comércio de Campo Grande-MS. Os experimentos foram conduzidos em um delineamento inteiramente casualizado, em esquema fatorial 3 X 6, com três espécies e seis procedências, totalizando 18 tratamentos. As variáveis analisadas foram: pureza física, primeira contagem do teste de germinação, germinação, valor cultural e massa de 1.000 sementes. Para análise estatística, os dados, quando necessário, foram transformados e as médias comparadas. Há grande variação na qualidade física e fisiológica das sementes de braquiárias comercializadas em Campo Grande-MS; as sementes da espécie B. humidicola, comercializadas em Campo Grande-MS são, em geral, de baixa qualidade física e fisiológica. Termos para indexação: Brachiaria brizantha, Brachiaria humidicola, Brachiaria decumbens, forrageiras, gramíneas. ABSTRACTThe present work was carried out at the Didactic Laboratory of Analysis of Seeds of the Universidade para o Desenvolvimento do Estado e da Região do Pantanal -UNIDERP, with the aim of evaluating the physical and physiological quality of seeds of three Brachiaria grass species (Brachiaria brizantha, B. humidicola and B. decumbens), proceeding from six companies located at the commercial area of Campo Grande (Brazil). The experiments were carried out in a completely randomized experimental design in factorial scheme, with four replications. The factors were: species (three) and origins (six); totalizing 18 treatments. The pureness, first counting of the germination test, germination, pure germinating seeds and biomass of 1,000 seeds were evaluated. For the statistical analysis, the data were transformed and the means were compared, when necessary. There is high variation in the physical and physiological quality of the seeds of Brachiaria grass commercialized in Campo Grande. The seeds with best physical and physiological quality of B. brizantha specie are from companies 1 and 4. The seeds of B. humidicola, commercialized in Campo Grande presents low physical and physiological quality as a whole. The seeds of B. decumbens with the best physical and physiological quality are from companies 1 and 6.
INTRODUCTION: Leprosy in Brazil is a public health issue, and there are many regions in the State of Espírito Santo with high endemic incidence levels of leprosy, characterizing this state as a priority for leprosy programs. The aim of this study was to determine the spatial distribution of coefficients of new cases of leprosy in the State of Espírito Santo, Brazil. METHODS: We conducted a descriptive and ecologic study based on the spatial distribution of leprosy in the State of Espírito Santo between 2004 and 2009. Data were gathered from the available records of the Espírito Santo State Health Secretary. The global and local Bayesian empirical methods were used to produce an estimate of leprosy risk, smoothing the fluctuation effects of the detection coefficients. RESULTS: The study resulted in a coefficient adjustment of new cases in 10 towns that changed their classification, among which, 2 went from low to medium, 4 from medium to high, 3 from high to very high, and 1 from very high to hyper-endemic. An average variation of 1.02, fluctuating between 0 and 12.39 cases/100,000 inhabitants, was found in a comparative calculation between the Local Ebest value and the average coefficient of new leprosy cases in the State of Espírito Santo. CONCLUSIONS: The spatial analysis of leprosy favors the establishment of control strategies with a better cost-benefit relationship since it reveals specific and priority regions, thereby enabling the development of actions that can interfere in the transmission chain.
