ABSTRACT

Introduction: Rita rita is a freshwater catfish under threat of extinction, mainly from loss of breeding and nursing grounds. A reliable method for age and growth estimation is needed by fishery managers. Objective: To identify the best body structure for age and growth estimation. Methods: We assessed estimates precision based on Average Percent Error (APE), Coefficient Variation (CV), and Percent Agreement (PA) between readers separately analyzed each calcified structure. We used 390 fish samples from three rivers, Ganga, Yamuna and Ramganga, from September 2018 to August 2019. Results: The three indicators favored the use of vertebrae for age estimation; the growth band seems to be annual and formed from May to September. The growth equations were Lt = 90.19(1-e-0.145(t+0.51)) for Ganga; Lt = 91.19 (1-e-0.14(t+0.59)) for Yamuna and Lt = 89.63 (1-e-0.15(t+0.68)) for Ramganga. Conclusion: This species reaches moderate growth in these rivers, where vertebrae are the recommended age estimation structure, followed, in case of need, by sectioned otoliths, whole otoliths and opercular bones. Pectoral spines should be avoided, especially in older fish.


Introducción: Rita rita es un pez de agua dulce bajo amenaza de extinción, principalmente por la pérdida de sitios de reproducción y crianza. Un método fiable para las estimaciones de edad y crecimiento es necesario para los administradores de recursos pesqueros. Objetivo: Identificar la mejor estructura corporal para estimaciones de edad y crecimiento. Métodos: Evaluamos la precisión de las estimaciones mediante el Porcentaje de Error Promedio (APE), Coeficiente de Variación (CV), y Porcentaje de Acuerdo (PA) entre lecturas para cada estructura calcificada. Usamos 390 muestras de peces de tres ríos, Ganga, Yamuna y Ramganga, de setiembre 2018 hasta agosto 2019. Resultados: Los tres indicadores favorecieron el uso de vértebras para la estimación de edad; la banda de crecimiento parece ser anual y se forma entre mayo y setiembre. Las ecuaciones de crecimiento fueron Lt = 90.19(1-e-0.145(t+0.51)) para Ganga; Lt = 91.19 (1-e-0.14(t+0.59)) para Yamuna y Lt = 89.63 (1-e-0.15(t+0.68)) para Ramganga. Conclusión: La especie alcanza un crecimiento moderado en estos ríos, dónde las vértebras son la estructura de estimación etaria recomendada, seguido de, en caso de ser necesario, los otolitos segmentados, otolitos enteros y huesos operculares. Debe evitarse el uso de espinas pectorales, especialmente en peces de mayor edad.

ABSTRACT

Introducción: El incremento matutino de la presión arterial detectado por monitoreo ambulatorio se asocia a daño de órgano blanco y a una mayor incidencia de eventos cardiovasculares. Objetivo: Determinar la adherencia terapéutica en hipertensos con incremento matutino de la presión arterial. Métodos: Se realizó un estudio transversal en 195 pacientes hipertensos ingresados en el servicio de medicina interna del Hospital Universitario Calixto García en el año 2018. Estos mostraron incremento matutino de la presión arterial y se valoró la adherencia terapéutica mediante el test de cumplimiento autocomunicado de Morisky-Green-Levine. Las variables identificadas como predictores relevantes de no adherencia fueron introducidas en un modelo multivariado de regresión logística. Resultados: 63,6 por ciento de los pacientes con incremento matutino de la presión fueron no adherentes, predominaron los pacientes del sexo masculino, 71,6 por ciento. El 84,0 por ciento (p=0,00) de los no adherentes ingerían de 3 a 4 fármacos antihipertensivos, 90,2 por ciento (p=0,00) tomaban 3 o más dosis. 50,5 por ciento de los pacientes tenía un diagnóstico de más de 5 años. Conclusiones: Los pacientes con incremento matutino de presión arterial se caracterizaron por ser no adherentes a la terapéutica antihipertensiva(AU)


Introduction: The morning hypertension detected by ambulatory monitoring is associated with target organ damage and a higher incidence of cardiovascular events. Objective: To determine the therapeutic adherence in hypertensive patients with a morning hypertension. Methods: A cross-sectional study was carried out in 195 hypertensive patients admitted to the internal medicine service at Calixto García University Hospital in 2018. They showed a morning increase of blood pressure and therapeutic adherence was assessed using the self-reported compliance test by Morisky-Green-Levine. The variables identified as relevant predictors of non-adherence were entered in a multivariate logistic regression model. Results: 63.6 percent of the patients with morning hypertension were non-adherent. Male patients predominated. 71.6 percent 84.0 percent (p = 0.00) of the non-adherents had 3 to 4 antihypertensive drugs, 90.2 percent(p = 0.00) took 3 or more doses. 50.5 percent of the patients were diagnosed for more than 5 years. Conclusions: Patients with morning hypertension were described as non-adherent to antihypertensive therapy(AU)

ABSTRACT

INTRODUCTION: Children and adolescents weight and height are a reflection of the health status and socioeconomic development of a population. OBJECTIVE: To evaluate height and weight progression patterns of Mexican children and compare them with Dr. Ramos-Galván growth charts 40 years later. METHOD: Cross-sectional survey conducted on the population of the National Physical Activation Program "Ponte al 100", which includes boys and girls aged six to 12 years. RESULTS: 43,670 boys and 44,103 girls were assessed, stratified by gender and age. The height progression pattern between six and 12 years was 21 cm in males and 22 cm in females, whereas the weight progression pattern was 9.86 and 10.05 kg, respectively, for males and females. The proportion of six- and 12-year-old boys who were overweight was 11.2 and 9 %, while 14.7 and 15 % were obese. The proportion of six- and 12-year-old girls who were overweight was 8.2 and 9.1 %, whereas 21.7 and 13.3 %, respectively, were obese. When the obtained values were compared with those of Dr. Ramos Galván growth charts for boys and girls, the average difference was 2 cm. CONCLUSIONS: No secular height or weight increase within the last 40 years was documented.

ABSTRACT

Terrestrial animals are negatively affected by habitat loss, which is assessed on a landscape scale, whereas secondary effects of habitat loss, such as crowding, are usually disregarded. Such impacts are inherently hard to address and poorly understood, and there is a growing concern that they could have dire consequences. We sampled birds throughout a deforestation process to assess crowding stress in an adjacent habitat remnant in the southern Brazilian Atlantic Forest. Crowding is expected of highly mobile taxa, especially given the microhabitat heterogeneity of Neotropical forests, and we hypothesized that the arrival of new individuals or species in refuges shifts assemblage patterns. We used point counts to obtain bird abundances in a before-after-control-impact design sampling of a deforestation event. Temporal changes in taxonomic and functional diversity were examined with metrics used to assess alpha and beta diversity, turnover of taxonomic and functional similarity, and taxonomic and functional composition. Over time increased abundance of some species altered the Simpson index and affected the abundance-distribution of traits in the habitat remnant. Taxonomic composition and functional composition changed in the remnant, and thus bird assemblages changed over time. Taxonomic and functional metrics indicated that fugitives affected resident assemblages in refuges, and effects endured >2 years after the deforestation processes had ceased. Dissimilarity of taxonomic composition between pre- and postdeforestation assemblages increased, whereas functional composition reverted to preimpact conditions. We found that ecological disruptions resulted from crowding and escalated into disruptions of species' assemblages and potentially compromising ecosystem functioning. It is important to consider crowding effects of highly mobile taxa during impact assessments, especially in large-scale infrastructure projects that may affect larger areas than is assumed.


Efectos del Amontonamiento debido a la Pérdida del Hábitat sobre los Patrones de Ensamblaje de las Especies Resumen Los animales terrestres se ven afectados negativamente por la pérdida del hábitat, la cual es evaluada con una escala de paisaje, mientras que los efectos secundarios de la pérdida del hábitat, como el amontonamiento, suelen ser ignorados. Dichos impactos son inherentemente difíciles de tratar y su entendimiento es muy pobre, además de que existe una preocupación creciente por las posibles consecuencias graves que podrían tener. Muestreamos aves durante un proceso de deforestación para evaluar el estrés por amontonamiento en un hábitat remanente contiguo a la parte sur del Bosque Atlántico Brasileño. Se espera que el amontonamiento ocurra en taxones con mucha movilidad, especialmente en el caso de los heterogéneos bosques Neotropicales, por lo que nuestra hipótesis consistió en suponer que la llegada a los refugios de nuevos individuos o especies modifica los patrones de ensamblado. Usamos el conteo por puntos para obtener la abundancia de las aves en un diseño de muestreo de antes-después-control-impacto de un evento de deforestación. Examinamos los cambios temporales en la diversidad taxonómica y funcional con medidas usadas para evaluar la diversidad alfa y beta, la rotación de la similitud taxonómica y funcional y la composición taxonómica y funcional. Con el tiempo, el incremento en la abundancia de algunas especies alteró el índice Simpson y afectó la abundancia y distribución de los caracteres en el hábitat remanente. La composición taxonómica y la composición funcional cambiaron en el hábitat remanente, por lo que los ensamblajes de aves cambiaron con el tiempo. Las medidas taxonómicas y funcionales indicaron que los individuos fugitivos afectaron a los ensamblajes de residentes en los refugios y sus efectos perduraron más de dos años después de que el proceso de deforestación había culminado. La disparidad de la composición taxonómica entre los ensamblajes antes y después de la deforestación incrementó, mientras que la composición funcional se revirtió a las condiciones previas al impacto. Encontramos que las perturbaciones ecológicas resultaron en el amontonamiento de especies y después escalaron hasta llegar a ser perturbaciones en el ensamblaje de las especies y potencial empobrecimiento del funcionamiento del ecosistema. Es importante considerar los efectos del amontonamiento de los taxones con mucha movilidad durante las evaluaciones de impacto ambiental, especialmente para proyectos con infraestructuras a gran escala que podrían afectar a un área mayor a la supuesta inicialmente.

ABSTRACT

RESUMEN El debate alrededor de las cifras de tensión arterial, y sobre todo las cifras a obtener mediante el tratamiento es en la actualidad un grave problema de salud. Se realizó una revisión sistemática en inglés y español de los principales artículos publicados en PubMed, Scielo y MEDLINE durante el periodo comprendido desde el año 2012 hasta 2018, acerca de la definición, evaluación y manejó de la tensión arterial. Todas las guías están de acuerdo en la toma de múltiples medidas de la tensión arterial para el diagnóstico, pero no para definir el control de la tensión, definir el control de la tensión arterial debe incluir una dimensión en el tiempo en un año por lo menos, y una proporción mínima de medidas donde debe pensar en la mitad de todas las medidas por lo menos, con medidas de tensión arterial tomadas por lo menos cada tres meses, por lo que sugerimos que un perfil anual de las cifras de tensión arterial debe ser considerado como un requisito mínimo para evaluar el control de la hipertensión arterial, este trabajo ha perfilado dos de los factores menos reconocidos: la necesidad de la intensificación del tratamiento después de la primera toma de tensión arterial por encima de las cifras deseadas, y el incremento de una nueva droga en vez de incrementar las dosis de las ya indicadas (AU).


ABSTRACT The debate on the maintained arterial tension measure, and on the measure to obtain through the long term treatment, is currently a problem for the medical practitioner, due to the variation of arterial tension during the day at different hours because of the patients circadian cycle, and due to variations in different days according to the proper patient's situations or the environment around it, and the different seasons of the year. They make it difficult to know when arterial tension is within the parameters accepted as "controlled". The authors carried out a systematic review of documents published in PubMed, Scielo and MEDLINE in the period 2012-2018, both in English and Spanish, on the arterial tension definition, evaluation and management. The guidelines agree in taking arterial tension measures in different moments for the diagnosis, but not in defining tension control. Defining tension control should include a time dimension of at least a year, and a minimal proportion of measures within the parameters recognized as non-pathological or optimal on the basis of measures taken at least every three months. Therefore, the authors suggest that an annual profile of the arterial tension parameters should be considered as a minimal requirement to evaluate arterial hypertension control (AU).

ABSTRACT

O araçá (Psidium cattleianum Sabine) é uma espécie frutífera nativa que possui importância econômica na indústria alimentícia e farmacêutica. Diante disto, há necessidade de produzir mudas de qualidade capazes de atender às demandas de mercado. Este trabalho teve como objetivo avaliar a influência do ambiente de crescimento e o uso do adubo de lenta liberação Osmocote® no desenvolvimento de mudas de araçá. Sementes de araçá foram coletadas em março de 2015 e germinadas. Depois de cerca de 90 dias, as mudas foram dispostas segundo os tratamentos que receberam. Os tratamentos consistiram em cinco doses de adubo (0; 3,0; 6,0; 9,0 e 12,0 g L-1) combinados com dois ambientes de viveiro (casa de vegetação e sombrite 50%) em esquema fatorial 5 x 2. Aos 210 dias avaliou-se altura de mudas (cm), diâmetro de colo (mm); peso seco de parte aérea e raiz (g) e índice de clorofila (SPAD). Houve interação dos fatores para a maioria das variáveis, com exceção do índice de clorofila. A dose intermediária do adubo implicou na melhor performance de crescimento de mudas em quase todas as ocasiões, assim como o ambiente sombreado. Para mudas de araçá, recomenda-se o uso de 6 mg L-1 de adubo e o uso de telado de sombrite para seu crescimento.(AU)


Araçá (Psidium cattleianum Sabine) is a native fructiferous species, of great economic importance in pharmaceutical and food industry. Therefore, there is a need to produce good quality seedlings capable of meeting market demands. The objective of this work was to evaluate the influence of the environment and the use of slow release fertilizer Osmocote® on the development of araçá seedlings. Araçá seeds were collected in March 2015 and germinated. After approximately 90 days, the seedlings were arranged for the treatments. The treatments consisted of five doses of fertilizer (0; 3.0; 6.0; 9.0 e 12.0 g L-1) and two environments, greenhouse and shade house (50%) in factorial scheme 5 x 2. At 210 days, we evaluated the height of seedlings (cm); collar diameter diameter (mm); dry weight of shoot and root (g) and chlorophyll index (SPAD). There was interaction of the factors for most of the variables, with the exception of the chlorophyll index. The intermediate dose of the fertilizer implicated in the best performance of growth of seedlings in almost all the occasions, as well as the shaded environment. For araçá seedlings, the use of 6 mg L-1 of fertilizer and a shade house environment are recommended for its better development.(AU)

ABSTRACT

RESUMEN La dimensión vertical de oclusión (DVO) está representada por la distancia entre dos puntos, que no se pierde; sin embargo, puede verse aumentada o disminuida. Depende en buena medida de la dentición presente. Entidades patológicas como la atrición severa pueden influir su condición. La ruta clínica para llegar a la determinación de realizar un incremento de DVO es un proceso meticuloso, parte de un diagnóstico certero, cuantificación de la misma, así como la vía para realizar el procedimiento. Existen múltiples métodos para la terapéutica del incremento de DVO: dispositivos removibles o fijos. La elección del plan de tratamiento será con base en las particularidades de cada paciente. No existe tratamiento universal sino uno ideal para cada situación específica. Este caso describe las consideraciones previas al aumento de DVO en un paciente masculino de 68 años con atrición generalizada. Se evaluó la magnitud de la reducción de DVO, perfil facial y estética mediante análisis fotográfico y video; el esquema oclusal y la estructura dental presente. La literatura propone calcular con diferentes métodos el restablecimiento de la DVO; antes de elegir alguno se requiere definir y especular qué tanto se encuentra disminuida, para ello no basta un análisis estático o de simple apreciación, debe considerarse el aspecto facial, así como la dinámica mandibular. El incremento de la DVO en una sola intención, mediante restauraciones provisionales, mantenidas dentro de los parámetros de comodidad, es un excelente recurso para ejecutarla, el paciente experimenta una fase de adaptación favorable y sin complicaciones sintomáticas.


ABSTRACT Occlusal vertical dimension (OVD) is represented by the distance between two points, which is not lost, however, can be increased or decreased. Depends to a good extent on the present dentition. Pathological entities such as severe attrition can influence their condition. Clinical route to arrive at the determination to perform an increase of OVD is a meticulous process, part of a correct diagnosis, quantifi cation of the same, as well as the way to perform the procedure. There are multiple methods for this treatment: removable or fi xed devices. Choice of treatment will be based on the particularities of each patient. There is no universal treatment but an ideal for each specific situation. This case describes the considerations prior to the increase of OVD in a 68-year-old male patient with generalized attrition. Magnitude of OVD reduction, facial and aesthetic profi le was evaluated by means of photographic and video analysis; the occlusal scheme and the dental structure present. Literature consulted proposes to calculate with different methods the reestablishment of OVD, before choosing one it is necessary to defi ne and to speculate how much it is diminished, for it is not enough a static analysis or of simple appreciation must consider the facial aspect, as well as the mandibular dynamics. Increasing OVD in a single intention, through provisional restorations, maintained within the parameters of comfort, is an excellent resource to execute it, the patient undergoes a phase of favorable adaptation and without symptomatic complications.

ABSTRACT

Abstract Objective. To estimate metabolizable energy requirements for maintenance (MEm), energy efficiency of weight gain (EEWG) and fat thickness, in Pelibuey and Katahdin ewes in Yucatan, Mexico. Material and method. Eight non pregnant, non lactating, multiparous ewes, were feed at three intake levels with a diet containing 2.0 Mcal/Kg-1 of ME and 11 % of CP. Feed intake was measured daily, ewes weight and thickness of subcutaneous fat (SF) were determined every 14 days. The EMm was estimated by regressing values of live weight against metabolizable energy intake (MEI), EEWG was estimate as gram of weight gain per Mcal of MEI. Results. There were no differences between breeds in MEm (97±4 and 110±4 kcal/Kg0.75, for Pelibuey and Katahdin) and EEWG (58±8 and 63±8 g/Mcal of MEI, for Pelibuey and Katahdin); differences were found in SF (6.1±0.2 and 4.9±0.2 mm, for Pelibuey and Katahdin). Conclusions. The energy requirements for maintenance were similar in Pelibuey and Katahdin ewes in Yucatan, Mexico.

ABSTRACT

Using morphometric measurements and wavelets functions, the asterisci otoliths of curimatã, Prochilodus nigricans were analysed to identify the variation in shape and growth increment of individuals from Solimões, Japurá and Negro rivers of the Amazon basin, Brazil. The morphometric and morphological analyses did not reveal evidences of population segregation among rivers, but variations were found in the estimation of otolith growth increment. Also, the otolith shape showed a high variability between individuals, identifying four morphotypes. Morphotype 1 shows a more oval shape with a posterior zone clearly rounded; Morphotype 2 shows the posterior zone rounded, but the anterior end is more elongated; Morphotype 3 shows a completely different shape, elliptic-pentagonal and Morphotype 4 shows the posterior zone rounded, but the anterior end is more elongated and it is the pattern with antirostrum and rostrum more pointed and a deep notch. Therefore, the otolith shape exhibited a phenotypic plasticity that it was not associated with the metabolism of otolith growth. Whereas the otolith shape indicated a homogeneity in the sound perception through Amazon basin, the growth rates revealed an adaptive mechanism to environmental conditions or migratory process of this species.(AU)


Medidas e funções wavelets dos otólitos asteriscus de curimatã, Prochilodus nigricans foram analisados para identificar a variação da forma e do incremento de crescimento dos indivíduos dos rios Solimões, Japurá e Negro da bacia Amazônica, Brasil. As análises morfométricas e morfológicas não revelaram evidências de segregação populacional entre os rios, mas foram encontradas variações na estimativa do incremento do crescimento dos otólitos. Além disso, a forma do otólito mostrou uma alta variabilidade entre os indivíduos, identificando quatro morfotipos. O Morfotipo 1 mostra uma forma mais oval, com zona posterior levemente arredondada; Morfotipo 2 mostra a zona posterior arredondada, mas a extremidade anterior é mais alongada; Morfotipo 3 mostra uma forma completamente diferente, elíptico-pentagonal e Morfotipo 4 mostra a zona posterior arredondada, mas a extremidade anterior mais alongada e ele tem padrão com antirostrum e rostrum mais pontiagudos e abertura profunda. Portanto, a forma do otólito exibiu uma plasticidade fenotípica que não foi associada ao metabolismo do crescimento do otólito. No entanto a forma do otólito indicou uma homogeneidade através da percepção do som na bacia Amazônica, e as taxas de crescimento revelaram um mecanismo adaptativo às condições ambientais ou ao processo migratório da espécie.(AU)

ABSTRACT

The aim of this study was to evaluate the growth responses of various Eucalyptus and Corymbia species subjected to different intensities of simulated hypergravity relative to the control. A centrifuge was used to simulate hypergravity. It was developed and built at the Centro de Microgravidade of the Pontifícia Universidade Católica do Rio Grande do Sul, Brazil. Seeds of five Eucalyptus and one Corymbia species (E. grandis, Eucalyptus globulus, Eucalyptus benthamii, Eucalyptus saligna, Eucalyptus dunnii, and C. maculata) were placed on moist germination paper in plastic containers and rotated at speeds simulating 5 Gz and 7 Gz for different lengths of time. Hypergravity technology significantly increased seedling production (diameter, height, and survival at 120 days) in nurseries. In E. globulus, the effects of hypergravity were significant at 7 Gz at all lengths of time (from 1 d to 9 days). Effects of hypergravity were significant in both E. benthamii and E. grandis at 7 Gz and 8 h exposure. Therefore, simulated hypergravity could be used in performance tests of Eucalyptus seedlings in early stages of development.(AU)


O presente trabalho objetivou avaliar o crescimento de espécies de Eucalyptus e Corymbia em diferentes intensidades de hipergravidade simulada em relação ao controle. Uma centrífuga foi usada para simular a hipergravidade. Este equipamento foi desenvolvido e construído no Centro de Microgravidade da Pontifícia Universidade Católica do Rio Grande do Sul, Brasil. Sementes de cinco espécies de Eucalyptus e uma de Corymbia (E. grandis, E. globulus, E. benthamii, E. saligna, E. dunnii, e C. maculata) foram colocadas em papeis de germinação e em recipientes plásticos, em que foram rotacionadas a velocidades simuladas de 5 Gz e 7 Gz, por diferentes períodos de tempo. A tecnologia da hipergravidade proporcionou aumento significativo na taxa de crescimento das plântulas (diâmetro, altura e sobrevivência aos 120 dias) no viveiro. Para Eucalyptus globulus, os efeitos da hipergravidade foram significativos na intensidade de 7 Gz em qualquer período de tempo (do primeiro até o nono dia). Os efeitos da hipergravidade foram significativos para as espécies E. benthamii e E. grandis na intensidade 7 Gz e 8 horas de exposição. Dessa maneira, a hipergravidade simulada apresenta potencial de uso em testes com plântulas de eucaliptos em estágios iniciais de desenvolvimento.(AU)

ABSTRACT

Studies on age and growth of fish populations have direct application in fisheries and contribute for policies of conservation. Our aim was update information on the Micropogonias furnieri growth parameters based on sagittae otoliths annulis readings, and we expected that the studied population from Southeast Brazil can reach more longevity than the reported in the available literature. We examined 286 individuals between August-2010 and July-2011 from Ubatuba Bay, SP. The Total Length ranged 200-480 mm. The determined growth parameters were: Males, L∞ =523.4mm, k = 0.05×year-1, t0 = -8.78 year; Females L∞ = 573.5mm, k = 0.06 × year-1, t0 = -7.49 year. The MI and % of edge type evidenced the formation of one ring per year during autumn/winter, coinciding with low temperature and low growth rate. These results differed from those reported for the Vazzolers Population I (summer), and we detected higher longevity (45-48 years) as compared with the recorded in the available information.(AU)


Estudos de idade e crescimento de peixes têm aplicação direta na biologia pesqueira e contribuem para medidas de conservação. Nosso objetivo foi atualizar informações sobre parâmetros de crescimento de Micropogonias furnieri utilizando leitura de anéis etários em otólitos sagittae, esperando que a população do Sudeste do Brasil alcance maior longevidade do que o reportado na literatura. Examinamos 286 indivíduos, capturados entre agosto de 2010 e julho de 2011, na Baía de Ubatuba, SP. O comprimento total variou de 200-480 mm. Foram determinados os parâmetros de crescimento: Machos, L∞ = 523,4 mm, k = 0,05 ano-1, t0 = -8,78 ano; Fêmeas, L∞ = 573,5 mm, k = 0,06 ano-1, t0 = -7,49 ano. O IM e a porcentagem do tipo de borda evidenciaram o padrão de formação anual de anéis no outono/inverno, coincidindo com mais baixas temperaturas e crescimento lento. Estes resultados diferem dos reportados para População I de Vazzoler (verão), e nós detectamos longevidade bem superior (45-48 anos) à descrita anteriormente.(AU)

ABSTRACT

O objetivo deste trabalho foi estudar os parâmetros de adaptabilidade e estabilidade fenotípica e avaliar o incremento na produtividade de grãos em genótipos de feijão preto, desenvolvidos pelos programas brasileiros de melhoramento genético entre os anos de 1960 a 2013. Os experimentos foram realizados considerando 38 cultivares e duas linhagens em quatro ambientes (Coimbra e Viçosa nas safras da seca e de inverno de 2013), usando um delineamento em blocos casualizados com três repetições. Os resultados evidenciaram incremento efetivo na produtividade de grãos, proporcionado pela recomendação de novas cultivares pelos programas de melhoramento de feijão do Brasil nas últimas cinco décadas. Além disso, a análise da interação GxA indicou que as cultivares recomendadas após o ano de 2005 foram as que apresentaram conjuntamente altas produtividades de grãos, ampla adaptabilidade e alta previsibilidade de comportamento.(AU)


The objective of this research was to study the parameters of adaptability and phenotypic stability and estimate the increase in grain yield in black common bean genotypes developed by brazilian breeding programs between the years 1960-2013. The experiments were carried out considering 38 cultivars and two lines in four different environments (Coimbra and Viçosa cities, and dry and winter seasons of 2013 year) by using a randomized block design with three replications. Results showed an effective increasing of the grain yield provided by the recommendation of new cultivars from different Brazilian breeding programs in the past five decades. In addition, the GxE analysis interaction indicated that cultivars recommended after the year 2005 were those with high average grain yield, wide adaptability and high predictability.(AU)
