ABSTRACT: The present study evaluated, through physical and physiological tests, the seed quality of a landrace fava bean variety in different packaging materials and storage periods, aiming to guarantee the conservation of their quality in seed banks and facilities. The methodology used was the one recommended by the Rules for Seed Analysis (RAS - Brasil, 2009) and minimum descriptors for Phaseolus lunatus L. The data were subjected to analysis of variance by the F-test at 5% signififance to verify the presence of significant interactions and the individual effects of each treatment. The test of multiple comparison of means was performed by the Tukey test at 5% significance between common treatments. The Dunnett test was used at 5% significance to compare the control means with the means of the treatments. Regression analysis was performed to study the effect of storage on the variables evaluated. All analyses were performed using the R software. From the results, it can be concluded that the storage of fava bean seeds is viable in small rural properties in impermeable packaging materials and aluminized polyethylene bags. The germination and vigor of the seeds analyzed in this study decreased throughout the storage period regardless of the type of packaging used. It is not recommended to store fava bean seeds in permeable paper packaging as they have the lowest quality indices (germination and vigor) at the end of the storage period.
RESUMO: O presente trabalho teve por objetivo avaliar por meio de testes físicos e fisiológicos a qualidade das sementes de uma variedade crioula de feijão-fava em diferentes embalagens. (1 -Embalagem cartonada mista composta por camadas de plástico, papel cartão e folha de alumínio impermeável- CN; 2- garrafa plástica semipermeável - PET;3- Pote plástico rígido impermeável - PEAD; 4- pote de vidro transparente quebrável impermeável - VIDRO; 5- saco plástico flexível impermeável PEBD aluminizado; 6- saco de papel permeável) e períodos de armazenamento de (90, 180, 270 e 360 dias), visando garantir a conservação da qualidade delas em casas e bancos de sementes. A metodologia utilizada foi a preconizada pelas Regras de Análise de Sementes (RAS - Brasil, 2009) e por descritores mínimos para Phaseolus lunatus L. Os dados foram submetidos a análise de variância pelo teste F ao nível de 5 %, afim de verificar a presença de interação significativa e dos efeitos simples de cada tratamento. Foi realizado o teste de comparação múltipla das médias pelos testes Tukey ao nível de 5 % de significância entre os tratamentos comuns. Para comparar as médias da testemunha com os tratamentos comuns recorreu-se ao teste Dunnett ao nível de 5 % de significância. Para estudar o efeito do armazenamento sobre as variáveis avaliadas foi feita a análise de regressão. Todas as análises foram feitas com o auxílio do R por meio de programação. Pelos resultados, pode-se concluir que o armazenamento de sementes de feijão-fava: é viável em pequenas propriedades rurais em embalagem impermeável; saco de polietileno aluminizada. A germinação e o vigor das sementes analisadas diminuíram ao longo do período de armazenamento, independentemente do tipo de embalagem utilizada. Não é recomendado armazenar sementes de feijão-fava em embalagens permeáveis de papel por apresentaram os menores índices de qualidade (germinação e vigor) ao final do período de armazenamento.

ABSTRACT The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classifications. In this context, the Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (http://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others. publications problem uptodate up date classifications context exception (CTFB http//fauna.jbrj.gov.br/, httpfaunajbrjgovbr http //fauna.jbrj.gov.br/ , jbrj gov br (http://fauna.jbrj.gov.br/) 2015 Brazil 80 specialists 1 2024 133691 133 691 133,69 125138 125 138 125,13 82.3%, 823 82 3 (82.3% 102000 102 000 102,00 7.69%, 769 7 69 (7.69% 11000 11 11,00 . 3,567 3567 567 (3,56 2,292 2292 2 292 (2,29 1,833 1833 833 (1,83 1,447 1447 447 (1,44 1000 1,00 831 (83 628 (62 606 (60 520 (52 50 users science health biology law anthropology education others http//fauna.jbrj.gov.br/ faunajbrjgovbr //fauna.jbrj.gov.br (http://fauna.jbrj.gov.br/ 201 8 202 13369 13 133,6 12513 12 125,1 82.3% (82.3 10200 10 00 102,0 7.69% 76 6 (7.69 1100 11,0 3,56 356 56 (3,5 2,29 229 29 (2,2 1,83 183 83 (1,8 1,44 144 44 (1,4 100 1,0 (8 62 (6 60 52 (5 5 http//fauna.jbrj.gov.br (http://fauna.jbrj.gov.br 20 1336 133, 1251 125, 82.3 (82. 1020 0 102, 7.69 (7.6 110 11, 3,5 35 (3, 2,2 22 (2, 1,8 18 (1, 1,4 14 4 ( 82.

ABSTRACT This paper reports on a study that investigated the experiences of 25 physical education (PE) teachers from public and private schools in Angeles City, Philippines, during the COVID-19 pandemic. The study found that many PE teachers encountered various challenges and were hesitant and unconfident about teaching PE during the pandemic. Additionally, many PE teachers were given non-teaching assignments and responsibilities, which added to their workload. The study highlights the importance of equipping teachers with the necessary skills and knowledge to adapt to the new teaching and learning modalities during the pandemic and providing support for PE teachers during this challenging time. The paper concludes by suggesting that future research could investigate the specific strategies and approaches that have been most effective in helping PE teachers overcome the challenges they face in teaching during the pandemic and the long-term effects of the pandemic on the teaching and learning of physical education. 2 (PE City Philippines COVID19 COVID 19 COVID-1 Additionally nonteaching non responsibilities workload time longterm long term COVID1 1 COVID-

Esse trabalho analisou a possibilidade de presença de efeito maternal na termotolerância em sementes de alface e buscou marcadores enzimáticos para tal. Usaram-se as cultivares Everglades (tolerante) e ‘Verônica’ (sensível), bem como seus híbridos recíprocos e a geração F2. As sementes foram analisadas quanto à germinação, bem como atividade enzimática (catalase, superóxido dismutase, ascorbato peroxidase e endo-β-mananase). O percentual de germinação; (primeira contagem e final), bem como a velocidade (IVG) foram analisados por meio de ANOVA e teste de Tukey. A cultivar Everglades e seus híbridos recíprocos não foram influenciados pela germinação em alta temperatura quando comparados com os outros tratamentos. Além disso, o efeito maternal foi observado na geração F1. Altas temperaturas interferem na atividade de todas as enzimas analisadas nesta pesquisa, consequentemente também nos parâmetros fisiológicos. Contudo, a superóxido dismutase e a endo-β-mananase tiveram suas variações altamente correlacionadas com as mudanças nos parâmetros fisiológicos. O presente trabalho evidenciou o efeito materno para a termotolerância em sementes de alface, bem como o uso da superóxido dismutase e endo-β-mananase como marcadores enzimáticos para tal característica.

Abstract: At higher temperatures, lettuce seeds may not germinate, resulting in problems for crop establishment in the field and production. This study aimed to evaluate the maternal effect for thermotolerance on lettuce seeds and find enzymatic markers. We used the thermoinhibition tolerant cultivar ‘Everglades’, the sensitive ‘Verônica’, their reciprocal hybrids, F1 and F2 generation. Seeds were submitted to germination and enzymatic tests (catalase, superoxide dismutase, ascorbate peroxidase, and endo- β-mannanase). Germination (first and final counting) and speed index were compared through Tukey’s test. ‘Everglades’ and its reciprocal hybrids, have not been influenced by temperature regarding germination compared to the other treatments. Also, the maternal effect was observed for the F1 generation. Higher temperatures interfere with the activity of all enzymes evaluated, consequently in the physiological parameters. However, superoxide dismutase and endo- β-mannanase have shown direct and more expressive correlation with changes on the physiological parameters compared to the other enzymes. Thus, it is possible to conclude that those enzymes can be used as markers for thermotolerant genotype selection.

ABSTRACT Physalis angulata L. (Solanaceae), known as ‘camapu’, has pharmacological and agroindustrial potentials, but information on the ecophysiological aspects that influence germination is scarce. In this context, the objective was to evaluate the expression of the physiological potential of P. angulata seeds as a function of the maturation stage, temperature, substrate and light condition. Four experiments were conducted: in the first, the maturation stages (green calyx + fruit, yellow calyx + fruit and light brown calyx + fruit) were evaluated at temperatures of 25, 30 and 35 °C, separately; in the second, the interaction between the temperatures of 35, 40 and 45 °C and types of substrate (on paper, between paper and between vermiculite) was tested in a 3x3 factorial scheme (temperatures as the first factor and types of substrates as the second factor); in the third experiment, the effect of light (absence of light, white light, red and far-red light) was evaluated; and, in the fourth, increasing values of photoperiods (0, 8, 12 and 16 hours) were used. In all experiments, the design was completely randomized with four replicates of 50 seeds. Analysis of the results showed that there was no interaction between the temperatures and the substrates tested, demonstrating the isolated action of the factors. P. angulata seeds expressed better physiological potential when the calyx and fruit are yellow. In the germination test, the seeds should be sown between paper towels, under temperature of 35 °C and absence of light.
RESUMO Physalis angulata L. (Solanaceae), conhecida por camapu, possui potenciais farmacológico e agroindustrial, porém são escassas as informações sobre os aspectos ecofisiológicos que influenciam a germinação. Neste sentido, objetivou-se avaliar a expressão do potencial fisiológico de sementes de P. angulata em função do estádio de maturação, temperatura, substrato e condição luminosa. Para isso, conduziram-se quatro experimentos: no primeiro, avaliou-se os estádios de maturação (cálice + fruto verdes, cálice + fruto amarelos e cálice + fruto marrom-claros) nas temperaturas de 25; 30 e 35 °C, separadamente; no segundo, testouse a interação entre as temperaturas 35; 40 e 45°C e tipos de substrato (sobre papel, entre papel e entre vermiculita) em esquema fatorial 3x3 (sendo o primeiro fato as temperaturas e o segundo os tipos de substratos); no terceiro experimento, avaliou-se o efeito da luz (ausência de luz, luz branca, luz na frequência do vermelho e do vermelho-distante); e, no quarto, utilizaram-se valores crescentes de fotoperíodos (0; 8; 12 e 16 horas). Em todos os experimentos o delineamento foi o inteiramente casualizado com quatro repetições de 50 sementes. Na análise dos resultados foi visto que não houve interação entre as temperaturas e os substratos testados, demonstrando a atuação isolada dos fatores. As sementes de P. angulata expressaram melhor potencial fisiológico quando o cálice e o fruto estão amarelos. No teste de germinação, as sementes devem ser semeadas entre papel toalha, sob a temperatura de 35 °C e ausência de luz.

Abstract Scientific diving (SD) is defined as any diving activity that applies scientific procedures to produce subsidies for studies and technical works in underwater environments. The first report of an underwater scientific study in Brazil dates to the 19th century, in the Abrolhos reefs. Currently, in Brazil, scientific diving has been performed in various areas, from shallow coastal regions to remote and sometimes hard-to-reach places, such as oceanic islands, flooded caves, and icy areas like Antarctica. However, the regulation of SD in Brazil still lacks more concrete actions towards an effective and efficient self-regulation that offers physical safety to practitioners and institutional safeguards for organizations that use it in their research projects. Thus, this article aims to contribute to a better understanding of this critical issue in Brazil and to serve as a reference and incentive for the training of professionals and the development of these activities in the country. It includes: 1) a historical review of SD; 2) a diagnosis of the training and application of SD in Brazil; 3) the evolution of marine sciences in Brazil from the perspective of SD; 4) a review of the use of environmental assessment and underwater conservation techniques in oceans and internal waters; 5) an analysis of the evolution of scientific diver training in Brazil, including a diagnosis on training; 6) the history and updates of the rules, regulations, and safety of SD. Given all the potential of diving combined with specific techniques for research, monitoring, and marine and limnic science in Brazil, we aim to understand the evolution of scientific diving teaching and to outline perspectives in the country, as it is crucial for the training of qualified scientists capable of performing these underwater tasks. Finally, we present future plans for the development of this activity in Brazil from the point of view of research and the labor market.

Abstract Citrus bergamia is a citric species known as bergamot. The species is widely used due to its derivatives, such as juices, extracts, and essential oil. Specifically, the bergamot essential oil (BEO) is of great interest, with a chemical composition rich in terpenes and esters. Considering its chemical composition, bioactivity, and great economic potential, the characterization of BEO should be studied. However, this essential oil is almost unexplored in terms of a characterization associated with colloids. Chemical characterization was carried out by gas-chromatography coupled to a mass spectrometer and by gas-chromatography coupled to a flame ionization detector. Antibacterial activity against Staphylococcus aureus and Escherichia coli was carried out to confirm the bioactivity of this important essential oil. Dynamic light scattering analysis was performed to create a pattern of droplet size distribution of BEO. Major compounds of BEO were linalyl acetate, limonene, and linalool. The BEO was active against E. coli and presented a MIC value of 2.000 µg/mL, while values of MIC and MBC higher than 2.000 µg/mL were observed for S. aureus. The dynamic light scattering analysis revealed a mean hydrodynamic diameter of 65.7 ± 2.2 nm. After a 1:10 dilution it was observed reduction of mean diameter and enhancement of the percentagem of low size droplets, resepctively 44.1 ± 1.2 nm and 14.5 ± 0.5 nm (28.8 ± 1.2%). Higher droplets and reduced polydispersity index were observed after 1:100 dilution. In the present study, the chemical characterization was in accordance with the species, as the characteristic chemical markers of the species were found. Moreover, it has presented antibacterial activity as expected for the BEO. The analysis of the colloid showed a pattern of droplet size distribution following the Ostwald ripening mechanism after dilution. derivatives juices extracts Specifically (BEO interest esters potential studied However colloids gaschromatography gas chromatography detector acetate limonene linalool E 2000 2 000 2.00 µgmL µg mL S 657 65 7 65. 22 2. 110 1 10 1:1 441 44 44. 12 1. 145 14 5 14. 05 0 0. 28.8 288 28 8 (28. 1.2%. 1.2% . 1.2%) 1100 100 study found Moreover 200 00 2.0 6 11 1: 4 28.

Resumo Citrus bergamia é uma espécie cítrica conhecida como bergamota amplamente utilizada industrialmente devido aos seus derivados, como sucos, extratos e óleo essencial. Especificamente o óleo essencial de bergamota (OEB) é de grande interesse, com uma composição química rica em terpenos e seus ésteres. Devido a sua composição química, bioatividade e grande interesse econômico, a caracterização do OEB deve ser alvo de estudos. No entanto, esse óleo essencial é praticamente inexplorado em termos de uma caracterização associada a coloides. Sua caracterização foi feita por cromatografia em fase gasosa acoplada à espectrômetro de massas e cromatografia em fase gasosa acoplada a detector de ionização de chamas. Atividade antibacteriana frente a Staphylococcus aureus e Escherchia coli foi realizada para confirmar a bioatividade do óleo essencial. Análise por espalhamento dinâmico da luz foi feita para criar um padrão de distribuição de tamanho de gotícula. Os constituintes majoritários foram o acetato de linalila, limoneno e linalool. O OEB foi ativo frente à E. coli, apresentando um valor de CMI igual à 2.000 µg/mL, enquanto values de CMI e CMB maiores do que 2.000 µg/mL foram observados frente à S. aureus.. A análise por espalhamento dinâmico da luz revelou um diâmetro hidrodinâmico médio de 65.7 ± 2.2 nm. Após diluição de 1:10, houve redução do diâmetro médio acompanhado de aumento do percentual de gotículas de baixo tamanho (14.5 ± 0.5 nm, 28.8 ± 1.2%). Foi observado aumento do tamanho e redução do índice de polidispersividade após uma maior diluição (1:100). Discussão: No presente estudo, a caracterização química está em consonância com a espécie, sendo encontrados os marcadores químicos da mesma. Além disso, o OEB apresentou a atividade antibacteriana esperada.

Resumen El jambú (Acmella oleracea [(L.) RK Jansen]) es una hortaliza de gran importancia para la región amazónica; se puede encontrar en la vida cotidiana de los ciudadanos del Estado de Pará (Brasil), ya que forma parte de platos tradicionales como pato en salsa de tucupi y salsa tacacá. Aunque el jambú es ampliamente cultivado, la información agronómica sobre su manejo sigue siendo escasa. El objetivo del presente estudio fue analizar el potencial fisiológico de las semillas de jambú almacenadas en diferentes envases y entornos. Los envases investigados comprendieron vidrio, tubos Eppendorf, bolsas de plástico y bolsas de papel acondicionados en frigorífico y en condiciones naturales en Castanhal, Pará, durante 360 días. La germinación de semillas, el primer conteo de germinación, las plántulas de emergencia, el índice de velocidad de germinación y emergencia, y el peso seco y la longitud de las plántulas fueron las variables evaluadas en intervalos de 40 días. El diseño experimental fue completamente al azar, con cuatro repeticiones de 50 semillas por tratamiento. Las semillas de jambú solo fueron influenciadas por factores del ambiente de almacenamiento; las semillas almacenadas en condiciones naturales registraron un comportamiento decreciente para las variables investigadas hasta llegar a cero, luego de 280 días de almacenamiento. Se pudo concluir que se conservó mejor el potencial fisiológico de las semillas de jambú almacenadas en refrigeración.
Abstract Jambu (Acmella oleracea [(L.) RK Jansen]) is a vegetable of great importance in the Amazonian region; it can be found in the daily life of the citizens of the State of Pará (Brazil), since it is part of traditional dishes such as duck in tucupi and tacacá sauce. Although jambu is widely cultivated, agronomic information about its management remains scarce. The aim of the current study was to analyze the physiological potential of jambu seeds stored in different packages and environments. The investigated packages comprised glass, Eppendorf tubes, plastic bags and paper bags conditioned in refrigerator and under natural conditions in Castanhal, Pará, for 360 days. Seed germination, first germination count, emergence seedlings, germination and emergence speed index, and seedling dry weight and length were the variables evaluated at 40-day intervals. The experimental design was completely randomized, with four replicates of 50 seeds per treatment. Jambu seeds were only influenced by the environment where they were stored; the ones stored under natural conditions recorded decreasing behavior for the investigated variables until they reached zero, after 280 storage days. It was possible to conclude that the physiological potential of jambu seeds stored in refrigerator was better conserved.

Resumen Las especies anuales generan costo de establecimiento varias veces por año, las praderas perennes permiten que la inversión inicial sea amortiguada durante dos o más años; sin embargo, las especies perennes tienen un establecimiento lento y compiten con hierbas indeseables, por lo que el presente trabajo de investigación tiene como objetivo determinar el rendimiento de una asociación ballico perenne (Lolium multiflorum L) y ebo (Vicia sativa L). La investigación se llevó a cabo en el campo experimental ‘Predio Nuevo’ del Colegio de Postgraduados, Texcoco, Estado de México. Se evaluaron las variables contenido de materia seca (MS), rendimiento de MS, relación hoja:tallo, material muerto, malezas y radiación interceptada. El primer muestreo fue a los 38 días, posterior a ello se realizaron cada 14 días, hasta los 150 cuando se hizo un corte mecánico, se hicieron dos cortes posteriores cada 28 días. Se observó un incremento progresivo conforme avanzó la edad hasta los 150 días (10 052 kg MS ha-1) así como 6 331 kg MS ha-1 y 6 397 kg MS ha-1 para el segundo y tercer corte. La MS se incrementó de 12.4 al 28.04% del día 38 al 150 para el primer corte y 26.67 y 27.2%, para el segundo y tercer corte. El material muerto se observó el día 80 con 0.84%, el valor ascendió a 17.3% para el día 150. La asociación de ballico perenne y ebo, aumenta el rendimiento de MS al primer corte sin afectar los rendimientos posteriores del cultivo perenne.
Abstract Annual species generate establishment costs several times per year, perennial grasslands allow the initial investment to be amortized for two or more years; however, perennial species have a slow establishment and compete with undesirable weeds, so the present research work aims to determine the yield of a perennial ryegrass (Lolium multiflorum L.) and common vetch (Vicia sativa L.) association. The study was conducted in the experimental field ‘Predio Nuevo’ of the College of Postgraduates, Texcoco, State of Mexico. The following variables were evaluated: dry matter (DM) content, DM yield, leaf:stem ratio, dead material, weeds and intercepted radiation. The first sampling was at 38 days, after that they were made every 14 days until 150 days when a mechanical cut was made, two subsequent cuts were made every 28 days. A progressive increase was observed as age progressed until 150 days (10 052 kg DM ha-1), as well as 6 331 kg DM ha-1 and 6 397 kg DM ha-1 for the second and third cuts. The DM increased from 12.4 to 28.04% from day 38 to 150 for the first cut and to 26.67 and 27.2% for the second and third cuts. The dead material was observed on day 80 with 0.84%, the value reached 17.3% for day 150. The association of perennial ryegrass and common vetch increases DM yield at the first cut without affecting the subsequent yields of the perennial crop.

Abstract The structural condition of the cable-stayed towers anchorage on power transmission lines requires constant monitoring. Maintenance routines must be able to identify faulty anchor rods and substitute them to avoid tower collapses and power delivery interruptions. Modern statistical diagnostic systems based on machine learning requires the generation of several distinct rod sample signals to be trained, which is a time-consuming process in typical electromagnetic solvers. Aiming to generate samples in a feasible time span, this paper presents a modeling strategy based on the cascade analysis of the transmission line composed by the anchor and the reference rods, interconnected by a dedicated high-frequency connector. Each distinct transmission line part is modeled by a quadrupole as a partial ABCD matrix. The complete response for each experimental setup is obtained from the cascaded-multiplying of the partial matrices. The proposed modeling proved to be accurate and provides a faster way to obtain the S-parameters from distinct faulty rods if compared to the traditional methodologies using electromagnetic tools.

Objective: To test the hypothesis that genetic variations of cannabinoid receptors contribute to the pathophysiology of cognitive deficits in schizophrenia. Methods: In this genetic association case-control study, cannabinoid receptor polymorphisms CNR1 rs12720071 and CNR2 rs2229579 were tested for association with neurocognitive performance in 69 patients with schizophrenia and 45 healthy controls. Neurocognition was assessed by the Brief Assessment of Cognition in Schizophrenia (BACS). Results: We found a consistent association between CNR1 rs12720071 polymorphism and the cognitive performance of patients in several cognitive domains. Patients with C/C polymorphism presented significantly worse performance in motor speed, verbal fluency, attention/processing speed and reasoning/problem solving. Conclusion: Although limited, our data support the hypothesis that CNR1 variations may be associated with the pathogenesis of cognitive deficits of schizophrenia.

ABSTRACT The growing consumer demand for sweet potato roots results in the need for genotypes with higher yields and better root quality. Thus, the objective of this study was to agronomically evaluate sweet potato genotypes via mixed models to select superior genotypes for human consumption and predict their selection gains. The study had a partially balanced triple lattice design with three replicates. As treatments, 92 sweet potato genotypes from the Universidade Federal de Lavras germplasm bank selected in the first selection cycle were evaluated along with eight controls, namely, Brazlândia Roxa, Princesa, Uruguaiana, BRS Amélia, Beauregard, UFVJM-57, UFVJM-58, and UFVJM-61. The treatments were ranked by the mixed linear model via restricted maximum likelihood (REML) and best linear unbiased prediction (BLUP). We highlighted the 15 best genotypes for each agronomic trait, then identified the best ones overall considering all quantitative and qualitative traits. High heritability was found for the trait commercial root yield (56.31%). For all traits, there were selection gains relative to the population mean. The use of mixed models was efficient for the selection of superior sweet potato genotypes. The genotypes 2018-19-464, 2018-72-1409, 2018-72-1428, 2018-19-443, 2018-36-807, 2018-72-1418, 2018-19-455, 2018-72-1376, 2018-54-1137, 2018-54-1114, 2018-65-1249, and 2018-28-556 have good traits related to commercial root yield and root quality and may be recommended for human consumption.

Abstract Worldwide, forests are susceptible to fire. Forests with fire and selective logging interactions require monitoring and evaluation. This study evaluated the phytosociology and dynamics of tree vegetation in a disturbed forest (DF) and an undisturbed forest (UF) in selective logging areas affected by fire, in the Brazilian East Amazon. All trees with DBH ≥ 5 cm were measured and identified botanically in 93 plots (5 X 50 m) in the DF area and 58 plots (5 X 50 m) in the UF area, in 2010 (before logging), 2011, 2015 and 2017 (two years after the fire). Analysis of species and tree composition, diversity, similarity, mortality and recruitment were carried out. The fire affected the DF and UF areas in a similar proportion in terms of trees loss and basal area, intensifying the mortality rate. In the short term (2 years), the fire did not cause a significant reduction in species diversity, but there was a tendency towards a similarity loss in species composition in the area disturbed by logging. Subsequent assessments are necessary to understand the forest’s recovery mechanisms.

Resumo: A deterioração por umidade na fase de pré-colheita prejudica a obtenção de sementes de soja de alta qualidade. Em seleção de genótipos, é comum a realização de vários testes para inferir sobre qualidade de sementes, sendo que a estatística multivariada pode auxiliar nas interpretações. O objetivo do trabalho foi avaliar a eficiência dos métodos de estatística multivariada de componentes principais (PCA) e discriminantes canônicos (CDA) na avaliação da tolerância de sementes de diferentes cultivares de soja à deterioração por umidade na fase de pré-colheita, em condições de casa de vegetação. Foram produzidas sementes de seis cultivares de soja (DM 6563, BMX Apolo, BMX Potência, NA 5909, NS 5959 e TMG 1175). Na fase de pré-colheita, foram aplicados diferentes níveis de precipitação simulada (0, 60, 120 e 180 mm). As sementes foram colhidas e avaliadas quanto a análises fisiológicas, físicas e bioquímicas e os dados obtidos foram analisados pelas técnicas PCA e CDA. Os resultados mostraram que a PCA e a CDA são eficientes para avaliação da tolerância à deterioração por umidade em sementes de soja. Na pré-seleção de genótipos para essa característica, a PCA e a CDA auxiliaram na recomendação dos testes de primeira contagem de germinação, envelhecimento acelerado, tetrazólio, porcentagem de sementes com enrugamento no tegumento, teor de proteínas e atividade da protease. A PCA e a CDA também auxiliaram na identificação das cultivares DM 6563 e BMX Potência como mais suscetíveis e as cultivares NA 5909 e TMG 1175 como mais tolerantes à deterioração por umidade na fase de pré-colheita.
Abstract: Weathering deterioration in the pre-harvest phase impairs high-quality soybean seed production. The performance of several tests to infer seed quality is common in genotype selection, and multivariate statistics can assist in the interpretations. This study aimed to assess the efficiency of the principal component analysis (PCA) and canonical discriminant analysis (CDA) multivariate statistical methods in assessing the tolerance of seeds of different soybean cultivars to weathering deterioration in the pre-harvest phase under greenhouse conditions. Seeds of six soybean cultivars (DM 6563, BMX Apolo, BMX Potência, NA 5909, NS 5959, and TMG 1175) were produced. Different simulated precipitation levels (0, 60, 120, and 180 mm) were applied in the pre-harvest phase. The seeds were collected and assessed for physiological, physical, and biochemical analyses and the data were analyzed by PCA and CDA techniques. The results showed that PCA and CDA are efficient for assessing the tolerance to weathering deterioration in soybean seeds. PCA and CDA assisted in the recommendation of the tests first germination count, accelerated aging, tetrazolium, percentage of seeds with seed coat wrinkling, protein content, and protease activity in the pre-selection of genotypes for weathering deterioration. PCA and CDA also helped to identify the cultivars DM 6563 and BMX Potência as more susceptible and NA 5909 and TMG 1175 as more tolerant to weathering deterioration in the pre-harvest phase.

Tannins are polyphenolic compounds with some beneficial properties for ruminants as they act as antioxidants, antimicrobials, and anthelmintics, which may improve animal performance. However, the results are variable, depending on the type, source, and dose. The objective of this research was to determine the effect on fattening performance and carcass characteristics of lambs supplemented with condensed tannins (CTs) from Acacia mearnsii extract. Thirty-six, three-month-old Dorset x Hampshire cross lambs of 20.8 ± 3.3 kg live weight were used in a completely randomized design with four treatments (n = 9), namely T1: basal diet, 0.0 g CT/kg DM-1; T2: T1 + 1.75 g CT/kg DM-1; T3: T1 + 3.5 g CT/kg DM-1; and T4: T1 + 5.25 g CT/kg DM-1. The daily weight gain was higher in T2 and T3 than in T1. The weight at slaughter and empty weight at slaughter were higher in T2 than in T1. The hot carcass weight was higher in T3 than in T1, but no different from T2 or T4. The hot carcass yield was higher in T3 than in the other treatments. The meat pH at slaughter and 24 hours postmortem was higher in T4 than in T1 and the meat protein percentage was higher in T3 than in T1. The inclusion of CTs from Acacia mearnsii extract in the diet of fattening lambs increased their daily weight gain, yield, and carcass weight.
