Characterization of white-fleshed peach cultivars grown in the ‘Zona da Mata’ area of Minas Gerais State, Brazil

There are few information on the physical and chemical characteristics of peach fruit in subtropical climate regions and the majority of the studies were developed in the southern region of Brazil. In this study, physical and chemical characteristics of 12 white-fleshed peach cultivars (Cristal, Cristal Tacoari, Colibri, Delicioso Precoce, Jóia 1, Jóia 2, Jóia 4, Marli, Okinawa, Pérola de Itaquera, Premier and Tropical) were evaluated. The cultivars were planted in the experimental orchard of the Federal University of Viçosa (UFV), Viçosa – MG, Brazil. The experiment was conducted during the 2011 harvest season, in a completely randomized design with 12 treatments (cultivars), three replications and 10 fruits per plot. The cultivars Delicioso Precoce and Marli showed, in general, higher mass and fruit diameter. Fruits of cultivars Jóia 2 and Tropical presented higher firmness. Cultivar Tropical stood out with better balance between acidity and soluble solids and higher vitamin C and carotenoids contents.There are few information on the physical and chemical characteristics of peach fruit in subtropical climate regions and the majority of the studies were developed in the southern region of Brazil.

Proline and ions accumulation in four Passiflora species under water-saline stress

Water-saline stress is one of the factors limiting growth and crop production, with the induction of morphological, structural and metabolic changes in higher plants. This study aimed to evaluate the response of four species with ten accessions of Passiflora to saline stress and drought stress, and the accumulation of proline and content of cationic macronutrients and their relationships with sodium. The plants were grown under controlled conditions for seven months, watered with nutrient solution with additions of NaCl (100 mM) to achieve the desired conductivities (1.5, 2.5, 4.0, and 5.5 dS m-1) and constant substrate humidity of 100%, 66% and 33%. The concentrations of Na+, K+, Ca++, Mg++ and proline in the leaves were determined. Proline accumulation increased in salinized plants, especially in young leaves. Proline increase was evident in accessions tolerant and moderately tolerant to salinity. These results indicate that tolerance to salinity and water stress in Passiflora relates to an improved ability to exclude sodium and greater ability to accumulate proline for osmotic adjustment. The increased salinity of the nutrient solution increased sodium contents, relations Na+/Ca++, Na+/Mg++, Na+/K+, and decreased Ca++, Mg++ and K+ levels, reflecting the nutritional imbalance caused by progressive saline stress.Water-saline stress is one of the factors limiting growth and crop production, with the induction of morphological, structural and metabolic changes in higher plants.

Tolerancia a la salinidad de Passiflora tarminiana Coppens & Barney

1 recurso en línea (páginas 11-19).Passiflora tarminiana es una glicofita trepadora, nativa de la región andina que tiene tolerancia a la salinidad y estrés hídrico moderado. El objetivo de este estudio fue evaluar la capacidad para la excreción de sodio como una posible estrategia de esta especie para la tolerancia a la salinidad y a la sequía. La excreción de sal y las concentraciones de iones excretados se examinaron en plantas cultivadas durante siete meses bajo varios niveles de salinidad [(NaCl) 2,5; 4,0 y 5,5 dS m-1 (25, 40 y 55 mM)] y de estrés hídrico moderado (33 y 100% de humedad en el sustrato). El experimento fue llevado a cabo en un diseño completamente al azar con un arreglo de parcelas subdivididas, donde la parcela constituye el porcentaje de saturación de agua (33 y 100%), la subparcela los niveles de saturación de sal (CE: 2,5; 4,0 y 5,5 dS m-1), con cinco repeticiones, y la unidad experimental compuesta por una planta. Se evaluaron los cristales de sal y las estructuras de la epidermis foliar. Las sales fueron excretadas en la superficie adaxial de la hoja, posiblemente debido a las glándulas secretoras de sal especializadas. Se observaron otras estructuras como tricomas y papilas, que se cree que también están implicadas en la tolerancia a la salinidad en P. tarminiana.moderate water stress. The aim of this study was to evaluate its capacity for sodium excretion as a possible strategy for salinity tolerance and the drought. Salt excretion and excreted ion concentrations were evaluated in plants grown for seven months under various levels of salinity [(NaCl) 2.5, 4.0, and 5.5 dS m-1 (25, 40 and 55 mM)] and moderate water stress (33 and 100% moisture in the substrate). The experiment design was completely randomized in a split-plot array, where the plot was determined by the percentage of water saturation (33% and 100%). The ubplot had saturation levels of salinity (EC: 2.5, 4.0, and 5.5 dS m-1), with five replicates. The experiment unit consisted of one plant. Salt crystals and structures of the leaf epidermis were evaluated. Salts were excreted in the adaxial leaf surface, possibly because of specialized salt secreting glands. Other structures, such as trichomes and papillae, were also observed, which are believed to also be involved in the salt tolerance of P. tarminiana.Bibliografía: páginas 18-1

COVID-19: RELATO PESSOAL SOBRE O ATENDIMENTO À POPULAÇÃO ATRAVÉS DE TELESSAÚDE

Telessaúde é uma ferramenta tecnológica que utiliza meios eletrônicos para transmitir informações e orientações relacionadas à saúde de forma não presencial. O governo do estado do Paraná, juntamente com a Fundação Araucária, no intuito de diminuir aglomerações populacionais nos serviços, criou uma plataforma de teleatendimento à saúde, onde atuam alunos, professores e diversos profissionais da área da saúde e afins. O presente relato de experiência, tem como objetivo descrever a perspectiva sobre a atuação junto ao novo cenário de telessaúde. Com a pandemia de um novo vírus respiratório, onde o ar é um meio de propagação, a telessaúde se tornou um importante aliado para o seu combate, pois sua funcionalidade e resolutividade é capaz de diminuir o fluxo dos serviços presenciais. O distanciamento social e outros fatores advindos do presente momento têm gerado um cenário populacional de busca por muitas orientações, que também são possíveis neste modelo de assistência, e de forma individualizada e humanizada

OS FLUXOS DE CAPITAIS INTERNACIONAIS PARA O FINANCIAMENTO E COMERCIALIZAÇÃO DA PRODUÇÃO AGROPECUÁRIA: UMA ANÁLISE DOS FATORES DE ATRAÇÃO E DE REPULSÃO

The recent capital flows to Brazil in the 1990’s decade are marked by a sharply expansion through the decade. This foreign financing has become an important alternative source explored by brasilian companies to increase their economic activities. The objective of this research work was to analyse both short and lond term relationship between the international capital flows directed to the rural sector and the influence of the pull factors (related to domestic specific factors) and the push factors (related to global factors). The montly data on the variables used, from January of 1991 to April of 1999, were taken from Banco Central do Brasil,  FGVDADOS, IBGE and Moody´s. The findings of this work estates that the variable that best explained these capital flows as its long terms determinants was the Brazilian sovereign rating defined by  Moody´s. The findings of this work estates as its short terms determinants both rating and international interest rate LIBOR, as well as its previous flows.  The explaining variables rating and international interest rates LIBOR fitted correctly to both short and long terms.Os fluxos de capitais internacionais direcionados para o Brasil ao longo da década de noventa têm sido bastante significativos.  O financiamento externo é uma modalidade alternativa que tem sido explorada por empresas brasileiras para incrementar suas atividades econômicas. Neste contexto, as organizações vinculadas ao agronegócio também têm utilizado instrumentos financeiros para a captação de recursos externos. O objetivo desta pesquisa foi analisar as relações de curto e longo prazo existentes entre os fluxos de capitais internacionais para o financiamento e comercialização da produção agropecuária brasileira e os fatores de atração e repulsão de capitais. Os dados mensais (de janeiro de 1991 a abril de 1999) foram coletados junto ao Banco Central do Brasil, FGVDADOS, IBGE e Agência Moody´s. Foi utilizado um modelo de correção de erro para avaliar as relações de curto e longo prazo. A variável explicativa que obteve o melhor resultado para o longo prazo foi o risco soberano do Brasil emitido pela agência Moody´s. Para o curto prazo, os fluxos foram influenciados tanto pelo risco do Brasil quanto pela taxa de juros LIBOR, bem como os fluxos de capitais registrados em instantes de tempo anteriores. As variáveis explicativas se comportaram de maneira coerente dentro das relações de curto e longo prazo

Morphological and genetic characterization of an emerging Azorean horse breed: the Terceira Pony

The Terceira Pony is a horse indigenous to Terceira Island in the Azores. These horses were very important during the colonization of the island and due to their very balanced proportions and correct gaits, with an average withers height of 1.28 m, the Terceira Pony is often confused with a miniature pure-bred Lusitano. This population was officially recognized as the fourth Portuguese equine breed by the national authorities in January 2014. The aim of this study was to analyze the morphology and the genetic diversity by means of microsatellite markers of this emerging horse breed. The biometric data consisted of 28 body measurements and 9 angles from 30 animals (11 sires, 19 dams).As the Terceira pony is now a recognized horse breed and gains popularity, primarily by breeders and the younger riding classes, the obtained information will be very useful for conservation and management purposes on maximizing its genetic diversity and solidifying the desirable phenotypic traits

Optimization of total carotenoids extraction from pequi pulp (Caryocar brasiliense Camb.) using a mixture planning method/ Otimização da extração de carotenoides totais da polpa de pequi (Caryocar brasiliense Camb.) usando método de planejamento de misturas

The pequi is a native fruit of the Brazilian Savanna and the consumption of its carotenoid-rich pulp has been associated with several health benefits. However, there are considerable differences in carotenoid content reported for this fruit, mainly due to the diversity of extraction methods used in the recovery of these compounds from pequi pulp. The objective of this study was to evaluate the efficiency of different organic solvents and mixtures in the extraction of total carotenoids from pequi pulp. For the carotenoids extraction, pure solvents and the mixtures of acetone, ethyl alcohol and petroleum ether were used. The mixture planning was used to determine the proportions of the solvents in each treatment. To our knowledge, this is the first study to identify that the most efficient treatment for total carotenoid extraction from pequi pulp is pure petroleum ether solvent (234.40 μg/g). In contrast, ethyl alcohol was the solvent that extracted the lowest concentration of total carotenoids (124.03 μg/g). Pure acetone, one of the most used solvents in the extraction of carotenoids from pequi, showed intermediate efficiency (166.07 μg/g). Thus, pure petroleum ether is the solvent recommended for total carotenoid extraction, mainly in the samples rich in carotenoid and lipids, such as pequi pulp

A detailed radio study of the energetic, nearby, and puzzling GRB 171010A

We present the results of an intensive multi-epoch radio frequency campaign on the energetic and nearby GRB 171010A with the Karl G. Janksy Very Large Array and Arcminute Microkelvin Imager Large Array. We began observing GRB 171010A a day after its initial detection, and were able to monitor the temporal and spectral evolution of the source over the following weeks. The spectra and their evolution are compared to the canonical theories for broadband GRB afterglows, with which we find a general agreement. There are, however, a number of features that are challenging to explain with a simple forward shock model, and we discuss possible reasons for these discrepancies. This includes the consideration of the existence of a reverse shock component, potential microphysical parameter evolution and the effect of scintillation
