Abstract: This article aims to identify and analyze dissertations and theses defended between 1972 and 2019, which used Vygotsky as a reference and dealt with pedagogical practices in the teaching of modern and contemporary physics in secondary schools. The theses were classified using institutional and pedagogical analysis descriptors to understand the main characteristics of each investigation. Thirty-four studies were found within this framework, most of which dealt with school practices related to astronomy and cosmology, quantum physics, and nuclear physics. Regarding pedagogical models, we found 18 studies aligned with the STS model and 16 with constructivist practices. These models use teaching methods and strategies close to Vygotsky’s sociocultural theory, and four use teaching strategies antagonistic to Vygotsky’s.

ABSTRACT Objective To describe an experience in the preoperative localization of small pulmonary nodules and ground-glass lesions to guide minimally invasive thoracic surgery; in addition, a literature review was conducted, including the main advantages and disadvantages of the different agents used, and site marking in a hybrid operating room. Methods A retrospective search was conducted in a Interventional Radiology Department database, between March 2015 and May 2019, to identify patients undergoing preoperative percutaneous marking of lung injuries measuring up to 25mm. Results A total of 20 patients were included and submitted to descriptive analysis. All patients were marked in a hybrid room, at the same surgical-anesthetic time. Most often used markers were guidewire, Lipiodol® and microcoils. Despite one case of coil displacement, two cases of pneumothorax, and one case of hypotension after marking, all lesions were identified and resected accordingly from all patients. Conclusion Preoperative percutaneous localization of lung injuries in hybrid room is an effective and a safe technique, which can have decisive impact on surgical resection. The choice of marker and of the operating room scenario should be based on availability and experience of service. Multidisciplinary discussions with surgical teams, pathologists, and interventional radiologists are crucial to improve outcome of patients.

Abstract Cordia trichotoma is a Brazilian species that has been studied for different forest systems. However, genetic breeding programs could highly improve species use. To obtain a better yield, it is essential to identify the species genotypes with superior performance. Thus, the work objective of this work was to estimate genetic divergence in two C. trichotoma progenies tests based on phenotypic traits. The experimental design adopted was the randomized blocks, one plant per plot, using 40 (area one) and 34 (area two) repetitions, using 3.0 m × 3.0 m spacing. The evaluated traits were diameter at 1.30 m above the soil (DBH-cm), total height (HT-m), collar diameter at 30 cm above the ground (DC-cm), and height of the first whorl (HFW-cm). The estimate of genetic divergence and the Tocher clustering method was performed using the REML / BLUP method. The genetic distances between the progenies in area 1 were 2.13 and 47.74 (17 and 15). In area two the genetic distances between the progenies were 3.64 (9 and 15) and 48.28 (12 and 7). The progenies formed 10 and 4 distinct groups, respectively, in area 1 and area 2). The traits that most contributed to genetic divergence were DBH-2016 (14.65%) in area one, and HT-2014 (14.32%) in area two. In sumary, the C. trichotoma progenies show high genetic divergence. Regarding breeding programs, it is recommended to cross progenies from the most divergent groups to heighten the genetic gain through the selection of more productive genotypes.

Resumen Cordia trichotoma es una especie nativa que está siendo evaluada para diferentes sistemas forestales. El hecho de que los individuos empleados en las plantaciones posean algún grado de mejoramiento genético tiene muchas ventajas; para lograr este mejoramiento es fundamental la obtención de genotipos superiores, a fin de obtener un mejor rendimiento del producto final. El objetivo del presente estudio fue estimar la divergencia genética de progenies de C. trichotoma en dos diferentes condiciones de textura de suelo, por medio de caracteres fenotípicos. El diseño experimental fue bloques completos al azar, un árbol por parcela con 40 (área 1) y 34 (área 2) repeticiones, con espaciamiento de 3,0 m × 3,0 m. Los caracteres evaluados fueron: diámetro a altura del pecho, altura total de plantas, diámetro de cuello y altura del primer verticilo. Para estimar la divergencia genética y el agrupamiento de Tocher fue utilizado el método REML/BLUP. Las distancias entre las progenies en el área 1 fueron de 2,13 y 47,74 (17 y 15), en el área 2 las distancias entre las progenies fueron de 3,64 (9 y 15) y 48,28 (12 y 7). Las progenies formaron diez y cuatro grupos distintos (área 1 y área 2). Los caracteres que más contribuyeron para divergencia genética fueron diámetro a la altura del pecho-2016 (14,65%) área 1, y altura total de plantas-2014 (14,32%) área 2. Las progenies de C. trichotoma presentaron alta divergencia genética. En programas de mejoramiento, se recomienda el cruzamiento entre progenies de los grupos más divergentes para priorizar la ganancia con selección de los genotipos más productivos.

Abstract Introduction Health problems in elderly individuals are diverse. The use of cigarettes, a potentially addictive substance, has been increasing in the elderly population age group, affecting the cognitive and elderly domains, and becoming an important global public health problem. Objective This study aimed to investigate the relationship between tobacco consumption by the elderly, as well as different levels of nicotine dependence and cognitive domains of executive functions. Method It is a case-control study composed by 58 individuals aged ≥ 60 years, with 29 participants in the clinical group and 29 in the control group. The case-control sample was paired in subgroups by sex, socioeconomic status, schooling, and sample isonomy with the clinical group. We used the Shapiro-Wilk normality test, the Mann-Whitney test, the student T-test, and the Cohen d-estimator. Results The control group performed better compared to the clinical group with the median grade in the inhibitory control of the executive domain with Cohen’s d 1.00 in the five-digit test and Cohen’s 1.5 in the Stroop test. The control group compared with the high-grade clinical group presented better performance with Cohen’s working memory of 1.56 d, Cohen’s inhibition of 1.06 d in the five-digit test, and Cohen’s of 1.17 d in the Stroop test. Discussion and conclusion The detection of the level of nicotine dependence is associated with the degree of cognitive impairment in the specific executive domain, which provides a possibility of differential diagnosis, both in the clinical and population contexts, directed at the rehabilitation of executive domains most affected by smoking in the elderly.

Resumen Introducción Los problemas de salud en las personas mayores son diversos. El consumo de tabaco, una sustancia potencialmente adictiva, ha aumentado en el grupo de edad de la población de ancianos, afectando los dominios cognitivos y de ancianos, convirtiéndose en un importante problema de salud pública mundial. Objetivo Este estudio tuvo como objetivo investigar la relación entre el consumo de tabaco en los ancianos, los diferentes niveles de dependencia de la nicotina y los dominios cognitivos de las funciones ejecutivas. Método Es un estudio de casos y controles, compuesto por 58 individuos de ≥ 60 años, con 29 participantes en el grupo clínico y 29 en el control. La muestra de casos y controles se emparejó en subgrupos por sexo, nivel socioeconómico, escolaridad e isonomía de la muestra con el grupo clínico. Se utilizaron la prueba de normalidad Shapiro-Wilk, la prueba de Mann-Whitney, la prueba Student T y el estimador d de Cohen. Resultados El grupo de control se desempeñó mejor en comparación con el grupo clínico con el grado medio en el control inhibitorio del dominio ejecutivo con Cohen’s d 1.00 en la prueba de cinco dígitos y Cohen’s 1.5 en la prueba de Stroop. En comparación con el grupo clínico de alto grado, el grupo de control presentó un mejor rendimiento con la memoria de trabajo de Cohen de 1.56 d, la inhibición de Cohen de 1.06 d en la prueba de cinco dígitos y la de Cohen de 1.17 d en la prueba de Stroop. Discusión y conclusión La detección del nivel de dependencia de la nicotina se asocia con el grado de deterioro cognitivo en el dominio ejecutivo específico, lo que brinda la posibilidad de un diagnóstico diferencial, tanto en el contexto clínico como en el de la población, dirigido a la rehabilitación de los dominios ejecutivos más afectados por el tabaquismo en los ancianos.

Abstract Aims: To analyze the effects of physical therapy procedures in reducing acute pain in runners. A second aim was to investigate the impact of weather conditions on the number of physical therapy visits during the Ultramarathon Rio24 h. Methods: This retrospective study was performed at the Physical Education Center Admiral Adalberto Nunes (CEFAN). Medical records were analyzed. The participants were athletes that were attended by the Physical therapy team during three editions of the Ultramarathon Rio24 h. The variation in the Visual Analog Scale score (VAS) before and after each treatment were analyzed. After the evaluation procedure, another professional had decided the best procedure for the assessed athlete: massotherapy, cryotherapy by immersion, or stretching. An ANOVA was performed to assess which procedures produce pain reduction immediately after the procedure. Results: A total of 1,995 care services (228 in women) were performed in 602 athletes (84 women). Analyzing the treatments that used only one modality (n = 512 visits), the final pain decreased significantly over the initial pain for the three treatments. It was verified that massotherapy, cryotherapy, and stretching promote significant intragroup differences, with no intergroup differences. The environmental conditions were not associated with the number of visits. Conclusion: Massotherapy, cryotherapy, and stretching are effective treatments for acute pain reduction during ultramarathons. The weather conditions are not associated with the number of physical therapy visits.

Abstract: En | Text: En | PDF: En

Abstract Objective Schizophrenia is a complex and chronic psychiatric disorder. In recent years, studies have found glutamatergic system participation in its etiopathogenesis, especially through aberrant NMDA receptors functioning. Thus, drugs that modulate this activity, as amantadine and memantine, could theoretically be used in its treatment. To perform a systematic literature review about memantine and amantadine use as adjunct in schizophrenia treatment. Methods A systematic review of papers published in English indexed in the electronic database PubMed ® using the terms “memantine”, “amantadine” and “schizophrenia” published until October 2016. Results We found 144 studies, 8 selected for analysis due to meet the objectives of this review. Some of these have shown benefits from such drug use, especially in symptoms measured by PANSS and its subdivisions, while others do not. Discussion: The data in the literature about these drugs use for schizophrenia treatment is still limited and have great heterogeneity. Thus, assay with greater robustness are needed to assess real benefits of these drugs as adjuvant therapy.

RESUMO Objetivo O estudo propôs-se a avaliar diferentes domínios das funções executivas em adolescentes como preditores ao uso de álcool e cigarro. Métodos Utilizou-se um delineamento transversal. A amostra foi composta por 239 adolescentes com idade média de 15,34 (±2,32). Os testes Alcohol Use Disorders Identification Test (AUDIT) e Fagerstrom Test for Nicotine Dependence (FTND) avaliaram o uso de álcool e cigarro respectivamente. O Self-Reporting Questionnaire (SRQ-20) foi utilizado para rastreio de saúde mental. Os testes Iowa Gambling Task (IGT), Wisconsin Card Sorting Test (WCST) e Continuous Performance Task (CPT) avaliaram os domínios executivos. Foi utilizado o estimador Odds Ratio adjusted (ORa). Resultados Os modelos logísticos ajustados demonstraram associação entre os domínios controle inibitório (ORa = 1.043; IC de 95% = 1,013-1,069; p = 0,001), flexibilidade cognitiva (ORa = 1.069; IC de 95% = 1,01-1,11; p = 0,001) e a tomada de decisão (ORa = 1.025; IC de 95% = 0,258-0,867; p < 0,014) e o uso de álcool. Também houve associação entre os domínios controle inibitório (ORa = 1.053; IC de 95% = 1,017-1,041; p = 0,003) e flexibilidade cognitiva (ORa =1.047; IC 95% = 1,004-1,250; p = 0,001) e o uso de cigarro. A faixa dos 14 aos 16 anos com 1,065 (ORa = 1.065; IC de 95% = 1,05-1,95; p = 0,010) razão de chances maiores para o uso de álcool e 1,067 (ORa = 1.067; IC de 95% = 0,156-1,453; p = 0,016) razão de chances para o uso de cigarro. Conclusão Os domínios cognitivos das funções executivas são fatores preditores associados ao uso de álcool e cigarro por adolescentes. Adolescentes com piores desempenhos nos domínios das funções executivas possuem maiores chances de fazer o uso de álcool ou cigarro.

ABSTRACT Objective The study proposes to evaluate different domains of executive functions in adolescents as predictors of alcohol and cigarette use. Methods A cross-sectional design was used. The sample consisted of 239 adolescents with a mean age of 15.34 (±2.32). The Alcohol Use Disorders Identification Test (AUDIT) and Fagerstrom Test for Nicotine Dependence (FTND) evaluated alcohol and cigarette use respectively. Self-Reporting Questionnaire (SRQ-20) for mental health screening. The Iowa Gambling Task (IGT), Wisconsin Card Sorting Test (WCST) and Continuous Performance Task (CPT) assessed executive domains. The adjusted Odds Ratio (ORa) was used. Results Adjusted logistic models showed an association between the inhibitory control domains (ORa = 1.043; 95% CI = 1.013-1.069; p = 0.001), cognitive flexibility (ORa = 1.069; 95% CI = 1.01-1.11; p = 0.001), and decision making (ORa = 1.025; 95% CI = 0.258-0.867; p < 0.014) and alcohol use. There was also an association between the inhibitory control domains (ORa = 1.053; 95% CI = 1.017-1.041; p = 0.003), and cognitive flexibility (ORa = 1.047; 95% CI = 1.004-1.250; p = 0.001), and tobacco use. The range from 14 to 16 years old with 1.065 (ORa = 1.065; 95% CI = 1.05-1.95; p = 0.010) was higher odds ratio for alcohol use, and 1.067 (ORa = 1.067; 95% CI = 0.156-1.453; p = 0.016) odds ratio for cigarette use. Conclusion The cognitive domains of executive functions are predictive factors associated with the use of alcohol and cigarettes by adolescents. Adolescents with worse performance in executive functions are more likely to use alcohol or cigarettes.

RESUMO As doenças do fígado e das vias biliares são causas comuns de morbidade e mortalidade. Procedimentos invasivos com finalidade diagnóstica e terapêutica são frequentemente recomendados nos casos de doenças hepatobiliares. O reconhecimento das indicações e limitações das técnicas comumente empregadas é crucial para uma adequada seleção dos pacientes, maximizando os resultados positivos e reduzindo o risco de complicações. Em 2018, a Sociedade Brasileira de Hepatologia (SBH), em colaboração com a Sociedade Brasileira de Radiologia Intervencionista e Cirurgia Endovascular (SOBRICE) e a Sociedade Brasileira de Endoscopia Digestiva (SOBED) realizaram um encontro exclusivamente voltado para a discussão dos procedimentos invasivos nas doenças hepatobiliares. Este texto resume as principais recomendações discutidas durante o evento, e tem a intenção de auxiliar clínicos, gastroenterologistas, hepatologistas, radiologistas e endoscopistas no uso adequado dos procedimentos invasivos para manejo de pacientes com doenças hepatobiliares.

ABSTRACT Liver and biliary tract diseases are common causes of morbidity and mortality worldwide. Invasive procedures are usually performed in those patients with hepatobiliary diseases for both diagnostic and therapeutic purposes. Defining proper indications and restraints of commonly used techniques is crucial for proper patient selection, maximizing positive results and limiting complications. In 2018, the Brazilian Society of Hepatology (SBH) in cooperation with the Brazilian Society of Interventional Radiology and Endovascular surgery (SOBRICE) and the Brazilian Society of Digestive Endoscopy (SOBED) sponsored a joint single-topic meeting on invasive procedures in patients with hepatobiliary diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to guide clinicians, gastroenterologists, hepatologists, radiologists, and endoscopists for the proper use of invasive procedures for management of patients with hepatobiliary diseases.

RESUMO Brycon nattereri é um peixe Neotropical ameaçado de extinção reportado para trechos conservados dos rios Paraná, Tocantins e São Francisco. Populações desta espécie têm sido muito raras em algumas sub-bacias do rio Paraná. Este estudo analisou a diversidade genética e a estrutura populacional de B. nattereri em uma área de ocorrência restrita recentemente identificada na bacia do alto rio Paraná. Sete locos microssatélites e 497 pb da região mitocondrial D-Loop foram examinados para 92 indivíduos de quatro pontos ao longo da área de ocorrência. Ambos os marcadores moleculares indicaram uma única população distribuída em um trecho de aproximadamente 80 km do rio. Embora alguns dados tenham sugerido um antigo gargalo genético, os atuais níveis de diversidade genética (H E = 0,574, h = 0,616) foram similares aos de outras espécies do gênero Brycon. Estes resultados sugerem que a população de B. nattereri tem mantido níveis satisfatórios de diversidade genética, apesar da pequena área de ocorrência. Estes dados destacaram uma importante área de conservação e ações podem melhorar a qualidade do ambiente, especialmente para a vida aquática e mata ciliar, se a área for eficientemente manejada e conservada.

ABSTRACT Brycon nattereri is an endangered Neotropical fish reported along conserved stretches of the upper Paraná, Tocantins and São Francisco rivers. Populations of this species have been very rare in some Paraná River sub basins. This study analyzes the genetic diversity and population structure of B. nattereri in a restricted area of occurrence recently identified in upper Paraná River basin. Seven microsatellite loci and 497 bp of D-Loop mitochondrial region were examined in 92 individuals from four points along the area of occurrence. Both molecular markers indicated a single population distributed along a stretch of the river approximately 80 km long. Although some of the data suggest an ancient bottleneck, current levels of genetic diversity (H E = 0.574 and h = 0.616) were similar to those of other species of the genus Brycon. The results suggest that the population of B. nattereri has been able to maintain satisfactory levels of genetic diversity, in spite of the small area of occurrence. These data have highlighted an important conservation area and action may prove essential to improve the quality of the environment, and especially the water and riparian plant life, if the area is to be managed and conserved efficiently.

RESUMO A pleurostomia é uma opção frequente de tratamento para pacientes com empiema pleural fase III que não toleram decorticação pulmonar. Todavia, esse tratamento é considerado mutilante por envolver a confecção de um stoma torácico, que pode demorar anos para se fechar ou requerer nova cirurgia. Descreveu-se recentemente uma técnica minimamente invasiva que associa uso intrapleural de curativo a vácuo como opção a pleurostomia. A presente comunicação objetiva demonstrar o resultado de uma série inicial de pacientes tratados com a minipleurostomia associada ao uso de curativo a vácuo no que tange a sua efetividade e segurança.

ABSTRACT Thoracostomy is a common treatment option for patients with stage III pleural empyema who do not tolerate pulmonary decortication. However, thoracostomy is considered mutilating because it involves a thoracic stoma, the closure of which can take years or require further surgery. A new, minimally invasive technique that uses the vacuum-assisted closure has been proposed as an alternative to thoracostomy. This study aims to analyze the safety and effectiveness of mini-thoracostomy with vacuum-assisted closure in an initial sample of patients.

ABSTRACT 24. Aims To investigate the home advantage (HA) in the Copa Libertadores da América (CLA) from 2005 to 2015. Methods A naive analysis was applied considering how many times a team that played the second leg at home qualified for the next round. To verify differences between home, away and draw results, the Chi-square ( χ2 ) and the Full Bayesian Significance Test were applied. For the binomial variables ("Home" or "Away"), the probability of second-leg knockout occurrence was calculated. Results The probability of second-leg HA varied from 27.27% to 63.64% suggesting fluctuations of second-leg HA during competitive phases (round of 16, quarterfinals, semi-finals and final matches) and decision forms (full time, goals away rule or penalty-shoots). Conclusion The results counteract the common belief that there is a large advantage to playing the second match of a two-leg tie at home during all competition phases. Penalty-shots seemed to affect positively the second-leg HA. Despite the causes of second leg HA in CLA need to be better investigated, soccer coaches could to use these results to think better strategies to win your knockout matches.

Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.

Observa-se, nos últimos anos, um importante crescimento do número de praticantes de corrida com proporcional aumento da adesão destes às provas de rua. Nesta população, a identificação dos determinantes do desempenho parece ser necessária para otimização do tempo dedicado ao treinamento. O objetivo do estudo foi estabelecer a associação do consumo máximo de oxigênio (VO2máx) estimado, da velocidade crítica (VC) e da velocidade do VO2máx (V VO2máx), com os desempenhos nas provas de 3,6 km em subida e 10 e 21,1 km no plano. Doze corredores amadores (9 homens) com 36 ± 5 anos de idade foram submetidos a quatro testes: 1 e 5 km de corrida, no plano; 3,6 km de corrida, com inclinação (≈8%); e um teste para determinação indireta do VO2máx. A VC foi determinada através da relação linear entre a distância e o tempo de corrida dos dois primeiros testes. Os sujeitos participaram de duas provas oficiais de 10 km e 21,1 km. A V VO2máx foi estimada a partir do VO2máx, através de equações metabólicas. O VO2máx apresentou a melhor associação com o desempenho da corrida em 10 e 21,1 km no plano. Já na subida, a V VO2máx apresentou melhor associação. Considerando todas as provas, a variável com maior média associativa foi o VO2máx (0,91±0,07), seguido do V VO2máx (0,90±0,04) e VC (0,87±0,06), respectivamente. Este estudo demonstrou elevadas associações entre variáveis fisiológicas estabelecidas por métodos indiretos, de baixo investimento e alta praticidade, com o desempenho da corrida em 10 e 21,1 km, no plano, e 3,6 km, em subida.

In recent years, there has been a substantial increase in the number of runners, with a proportional increase in their involvement in amateur street competition. Identification of the determinants of performance in this population appears necessary for optimization of time devoted to training. The objective of this study was to ascertain the association between estimated maximal oxygen uptake (VO2max), critical velocity (CV) and VO2max velocity (V VO2max) and athletic performance in the 3.6 km (uphill) and 10 and 21.1 km (flatland) events. Twelve amateur runners (nine male), mean age 36 ± 5 years underwent five tests: 1 and 5 km race on level ground, 3.6 km race with slope (≈8%), and indirect VO2max measurement. CV was determined from the linear relationship between distance and run time on the first two tests. The subjects then took part in two official 10 km and 21.1 km (half marathon) races. V VO2max was calculated from the VO2max through a metabolic equation. VO2max showed the best association with running performance in the 10 and 21.1 km events. For the uphill race, V VO2max showed a better association. Overall, the variable with the highest average association was VO2max (0.91±0.07), followed by V VO2max (0.90±0.04) and VC (0.87±0.06). This study showed strong associations between physiological variables established by low-cost, user-friendly indirect methods and running performance in the 10 and 21.1 km (flatland) and 3.6 km (uphill) running events.

(Nota sobre a germinação de sementes de Vochysia tucanorum tratadas com reguladores vegetais). O objetivo deste trabalho foi avaliar a resposta germinativa sob luz branca e escuro de sementes de Vochysia tucanorum Mart. tratadas com GA3 e CEPA. Sementes recém-coletadas de uma área de Cerrado foram armazenadas durante 14 dias em duas temperaturas (25 ± 2 °C e 7 ± 1 °C). Após o período de armazenamento, as sementes foram pré-tratadas com água destilada (controle), ácido giberélico (GA3), ácido 2-cloroetilfosfônico (CEPA) e uma mistura de GA3 + CEPA; em seguida, as sementes foram semeadas em placas de Petri sobre papel filtro umedecido com água destilada e colocadas para germinar em escuro e sob luz branca. Os resultados sugerem que as sementes não são fotoblásticas nem dormentes, no entanto um comportamento fotoblástico emerge quando as sementes foram previamente armazenadas em baixa temperatura e embebidas em soluções de GA3 e CEPA. Em geral, não houve diferença entre as temperaturas de armazenamento de 7 °C e 25 °C. A germinação sob luz branca de sementes pré-tratadas com CEPA + GA3 e CEPA foi antecipada, em comparação com o controle de água destilada, sendo que o efeito da mistura CEPA + GA3 foi mais pronunciado do que o de CEPA sozinho. Assim, a taxa de germinação de sementes de V. tucanorum, sob luz branca, pode ser melhorada pela embebição das mesmas em soluções de CEPA ou de CEPA + GA3.

(Note on the germination of Vochysia tucanorum seeds treated with growth regulators). The aim of this work was to evaluate the germination response of Vochysia tucanorum Mart. seeds treated with GA3 and CEPA and germinated under white light or darkness. Newly collected seeds from a Cerrado area were stored for 14 days at two temperatures (25 °C ± 2 and 7 °C ± 1). After the storage period the seeds were pre-treated with distilled water (control), gibberellic acid (GA3), 2-chloroethylphosphonic acid (CEPA) and a mixture of GA3 + CEPA. Following this, the seeds were sown in Petri dishes on filter paper moistened with distilled water and germinated in either darkness or white light. The results suggest that seeds are non-photoblastic and non-dormant, however a photoblastic behavior emerges when the seeds were previously stored at low temperature and imbibed in CEPA and GA3 solutions. In general, there is no difference between the 7 °C and 25 °C storage temperatures. The germination of seeds pre-treated with CEPA and CEPA + GA3 under white light was faster as compared to the distilled water control, and the effect of the CEPA + GA3 mixture was more pronounced than CEPA alone. Thus, the germination rate of V. tucanorum seeds can be improved by treatment with CEPA or CEPA + GA3 under white light.
