ABSTRACT OBJECTIVE To evaluate the quality of information on gestational syphilis (GS) and congenital syphilis (CS) on the Sistema de Informação de Agravos de Notificação (SINAN-Syphilis Brazil – Notifiable Diseases Information System) by compiling and validating completeness indicators between 2007 and 2018. METHODS Overall, care, and socioeconomic completeness scores were compiled based on selected variables, by using ad hoc weights assigned by experts. The completeness scores were analysed, considering the region and area of residence, the pregnant woman’s race/colour, and the year of case notification. Pearson’s correlation coefficients were used to validate the scores obtained by the weighted average method, compared with the values obtained by principal component analysis (PCA). RESULTS Most selected variables presented a good or excellent degree of completeness for GS and CS, except for clinical classification, pregnant woman’s level of education, partner’s treatment, and child’s race/colour, which were classified as poor or very poor. The overall (89.93% versus 89.69%) and socioeconomic (88.71% versus 88.24%) completeness scores for GS and CS, respectively, were classified as regular, whereas the care score (GS-90.88%, and CS-90.72%) was good, despite improvements over time. Differences in the overall, care and socioeconomic completeness scores according to region, area of residence, and ethnic-racial groups were reported for syphilis notifications. The completeness scores estimated by the weighted average method and PCA showed a strong linear correlation (> 0.90). CONCLUSION The completeness of GS and CS notifications has been improving in recent years, highlighting the variables that form the care score, compared with the socioeconomic scores, despite differences between regions, area of residence, and ethnic-racial groups. The weighted average was a viable methodological alternative easily operationalised to estimate data completeness scores, allowing routine monitoring of the completeness of gestational and congenital syphilis records.

Abstract Essential oils have been widely studied because they are natural sources of substances that have antimicrobial properties. In fruit growing, especially in mango crop, anthracnose (Colletotrichum gloeosporioides) is considered the main disease because it causes series of damages in the fruit production chain and, in this sense, essential oils can be an option in this disease control. The objective of this study was to evaluate the effect of essential oils obtained from the leaves of Chá-de-moça (Pectis brevipedunculata) and Melosa (Dizygostemon riparius) in the in vitro and in vivo control of the C. gloeosporioides fungus, in seedlings and mango fruits. The in vitro bioassays were performed by testing the effect of different concentrations of essential oils (0, 1, 2, 3 and 4 µl/mL) on the reduction of mycelial growth of the C. gloeosporioides fungus. Additionally, the anthracnose control in mango seedlings (Tommy Atkins, Constantina, Comum and Rosa cultivars) was evaluated by foliar application of essential oils at 4 µl/mL concentration. Disease control in fruits of the same mango cultivars was evaluated at 3 µl/mL concentration of essential oils. The evaluation was carried out by measuring the average diameter of the colonies, for the in vitro treatment, and the lesions for the in vivo treatments, in two diametrically opposite directions. There was a decrease in the fungus mycelial growth in all tested concentrations. There was a decrease in the disease severity from the sixth day after the oils application in Tommy Atkins cultivar seedlings, when treated with both essential oils at 4 µl/mL concentration. As for preventive treatments with fruits, it was observed that all cultivars achieved a reduction in severity from 54.83% at 3 µl/mL concentration with the use of both essential oils. Given the results obtained, it was observed that the essential oils P. brevipedunculata and D. riparius can be a viable alternative in the anthracnose control in mango culture.

Resumo Os óleos essenciais têm sido largamente estudados por serem fontes naturais de substâncias que possuem propriedades antimicrobianas. Na fruticultura, especialmente na cultura de manga, a antracnose (Colletotrichum gloeosporioides) é consideradaa principal doença por causar uma série de prejuízos na cadeia produtiva dos frutos, e,nesse sentido,os óleos essenciais podem ser uma opção no controle desta doença. O objetivodeste trabalho foi avaliar o efeito dos óleos essenciais obtidos das folhas de Chá-de-moça (Pectis brevipedunculata) e Melosa (Dizygostemon riparius) no controle in vitro e in vivo do fungo C. gloeosporioides, em mudas e frutos de mangueira. Os bioensaios in vitro foram realizados testando-se o efeito de diferentes concentrações dos óleos essenciais (0; 1;2; 3 e 4 µl/mL) sob a redução do crescimento micelial do fungo C. gloeosporioides.Adicionalmente, avaliou-se o controle da antracnose em mudas de manga (cultivares Tommy Atkins,Constantina, Comum e Rosa), pela aplicação foliar dos óleos essenciais, na concentração de 4 µl/mL. O controle da doença em frutos das mesmas cultivares de manga foi avaliado naconcentração de 3 µl/mL dos óleos essenciais. A avaliação foi feita pela mensuração dodiâmetro médio das colônias, para o tratamento in vitro, e das lesões, para ostratamentos in vivo, em dois sentidos diametralmente opostos. Houve diminuição do crescimento micelial do fungo em todas as concentrações testadas. Observou-se diminuição na severidade dadoença a partir do sexto dia após aplicação dos óleos nas mudas de cultivar Tommy, quandotratada com ambos os óleos essenciais, na concentração de 4 µl/mL. Já para os tratamentospreventivos com frutos, foi observado que todas as cultivares obtiveram redução daseveridade a partir de 54,83%, na concentração de 3 µl/mL, com uso de ambos os óleos essenciais.Diante dos resultados obtidos, foi observado que os óleos essenciais P. brevipedunculata e D. ripariuspodem ser uma alternativa viável no controle de antracnose na cultura de manga.

Thermo-responsive copolymers grafted with N-isopropylacrylamide (NIPAm) are excellent candidates for drug release. Dextran sulfate (DS) acts as a specific ligand in inflamed regions, turning it highly useful as a target for drug delivery. DS was associated with NIPAm to produce amphiphilic graft copolymers prepared via free radicals. The molar ratio of feed reagents NIPAm/DS varied from 1 (DS-g-PNIPAm) to 4 (DS-g-4PNIPAm). The synthesis was confirmed by spectroscopic techniques (Fourier transform infrared (FTIR) and nuclear magnetic resonance (NMR)). All copolymers showed self-organization capacity in an aqueous medium in temperatures higher than 34 °C, and sizes less than 300 nm. DS-g-3PNIPAm exhibited stability in water and in phosphate buffer at pH 7.4. Scanning electron microscopy confirmed their spherical shape. This copolymer showed specificity to leukemic cells, and normal cells’ proliferation. Methotrexate (MTX) is a very low water-soluble drug used for rheumatoid arthritis and cancer. Unfortunately, MTX have severe collateral effects. MTX-loaded nanoparticles can overcome such issues as well as enhance bioactivity and stability. The MTX was encapsulated and delivered from the DS-g-3PNIPAm with potential target delivery due to the presence of DS. Comparison with MTX encapsulated in other nanoparticles reveals that the DS-g-PNIPam presents the best performance among the thermo-responsive and the second among the target MTX nanocarriers.

Abstract Fifteen polar extracts from leaf, seed, pod, stem, flower and root of Crotalaria spectabilis were prepared using aqueous systems, based on the principles of green chemistry, and showed different protease inhibitor (PI) activities on trypsin, papain, pepsin and the extracellular L. amazonensis serine protease (LSPIII). The most pronounced inhibitory effect on LSPIII was observed in leaf (CS-P), root, stem, flower (CS-FPVPP) and pod (CS-VA) extracts. Crotalaria extracts exhibited low cytotoxicity on macrophages; however, they decreased the viability of L. amazonensis promastigotes and amastigotes, as observed in leaf (CS-AE, CS-P, CS-T and CS-PVPP), seed (CS-ST), flower and root (CS-RA) extracts. CS-P was chosen to study PI and secondary metabolites and a 10-12 kDa protein, analyzed by mass spectrometry, was identified as a serine PI homologous with papaya latex serine PI. Glycosylated flavonoids, such as quercetins, vitexin and tricin were the major secondary metabolites of CS-P. The presence of PIs in C. spectabilis is a new finding, especially in other organs than seeds since PIs have been reported only in seed legumes. Besides, this is the first report of antileishmanial activity of C. spectabilis extracts and the identification of serine polypeptide PI and glycosylated flavonoids from leaf.

The pequi pericarp corresponds to the largest portion of the fruit and has a high nutritional value, but it is discarded as an agro-industrial residue. The present study aimed to prepare and characterize flours from the pequi pericarp in terms of their proximate composition, its antioxidant potential before and after the in vitro digestibility process and chemical profile, aiming at the full use of this fruit. The samples of pequi pericarp flours from the cities of Sete Lagoas, Paraopeba and Felixlândia were analyzed. The profile of chemical compounds present in the flours was determined using paper spray mass spectrometry. The in vitro simulated digestion technique was used to verify the stability of the phenolic compounds and the maintenance of the antioxidant capacity of the samples. The flours from the pequi pericarp showed to have higher levels of protein, ash and dietary fiber, compared to the data described in the literature for the pulp of the fruit. The analysis of paper spray mass spectrometry allowed the identification of 46 chemical compounds including amino acids, sugars, organic acids and phenolic compounds. The analysis of the main components showed that there was no chemical variation among the fruits from the cities studied. Through the in vitro digestibility technique, it was possible to observe an increase in the bioaccessibility of phenolic compounds, contributing to increase the already significant antioxidant capacity of the samples. It was concluded that the pequi pericarp flour has the potential to be used as a food ingredient due to the high bioaccessibility of its bioactive compounds, capable of reducing the risk of developing diseases caused by oxidative stress.

Resumo: O objetivo deste artigo foi avaliar os fatores socioeconômicos, familiares e individuais associados ao desenvolvimento infantil no primeiro ano de vida, entre famílias em vulnerabilidade social. Trata-se de uma análise transversal, com dados da linha de base de um ensaio randomizado. O estudo incluiu 3.242 crianças < 12 meses de idade, residentes em 30 municípios de cinco regiões do Brasil. A escolha de estados e municípios foi intencional, tendo como base a implementação do Programa Criança Feliz. A amostra foi selecionada a partir de crianças elegíveis para o Programa Criança Feliz, cujo objetivo é promover a estimulação e o desenvolvimento infantil. O Ages and Stages Questionnaire (ASQ) foi utilizado para avaliação do desenvolvimento infantil. Um modelo de análise multinível em três níveis (estado, município e indivíduos), usando teste de Wald para heterogeneidade e tendência linear, estimou a média do ASQ-3 e intervalo de 95% de confiança (IC95%). Análises foram ajustadas para potenciais confundidores. Foram analisadas informações de 3.061 (94,4%) crianças com dados disponíveis para ASQ-3. Escores de desenvolvimento infantil (total e em todos os domínios) foram cerca de 12% menores em crianças nascidas pré-termo e com restrição do crescimento intrauterino (pequenas para idade gestacional). Observou-se menores escores em filhos de mães com baixa escolaridade, com sintomas de depressão, com duas ou mais crianças menores de sete anos residindo no domicílio e que não relataram autopercepção de apoio/ajuda durante a gestação. Conclui-se que características potencialmente modificáveis (escolaridade, depressão materna e prematuridade/restrição do crescimento intrauterino) apresentaram maior impacto na redução do escore de desenvolvimento em todos os domínios avaliados.

Abstract: The study aimed to assess socioeconomic, family, and individual factors associated with infant development (i.e., in the first year of life) among families with social vulnerability. This was a cross-sectional analysis of baseline data from a randomized trial. The study included 3,242 children < 12 months of age living in 30 municipalities from five regions of Brazil. The choice of states and municipalities was intentional, based on the implementation of the Brazilian Happy Child Program. The sample was selected among eligible children for the Brazilian Happy Child Program, and the objective was the promotion of infant development. The Ages and Stages Questionnaire (ASQ) was used to assess infant development. A three-level analytical model (state, municipality, and individuals), using the Wald test for heterogeneity and linear trend, estimated the mean ASQ-3 and 95% confidence interval (95%CI). The analyses were adjusted for potential confounders. Information was analyzed for 3,061 (94.4%) children with available data for ASQ-3. Infant development scores (total and in all the domains) were some 12% lower in preterm children and those with intrauterine growth restriction (small for gestational age). Lower scores were seen in children of mothers with low schooling, depressive symptoms, two or more children under seven years of age living in the household, and who did not report self-perceived support or help during the pregnancy. In conclusion, potentially modifiable characteristics (schooling, maternal depression, and prematurity/intrauterine growth restriction) showed greater impact on reducing the infant development score in all the target domains.

Resumen: El objetivo fue evaluar los factores socioeconómicos, familiares e individuales, asociados al desarrollo infantil en el primer año de vida, entre familias con vulnerabilidad social. Se trata de un análisis transversal, con datos de la base de referencia de un ensayo aleatorio. El estudio incluyó a 3.242 niños < 12 meses de edad, residentes en 30 municipios de cinco regiones de Brasil. La elección de estados y municipios fue intencional, considerando como base la implementación del Programa Niño Feliz. La muestra se seleccionó a partir de niños elegibles para el Programa Niño Feliz, cuyo objetivo es promover la estimulación y el desarrollo infantil. Se utilizó el Ages and Stages Questionnaire (ASQ) para la evaluación del desarrollo infantil. Un modelo de análisis multinivel en tres niveles (estado, municipio e individuos), usando el test de Wald para la heterogeneidad y tendencia lineal, estimó la media del ASQ-3 y el intervalo de 95% de confianza (IC95%). Los análisis se ajustaron para potenciales factores de confusión. Se analizó información de 3.061 (94,4%) niños con datos disponibles para ASQ-3. Las puntuaciones de desarrollo infantil (total y en todos los dominios) fueron cerca de un 12% menores en niños nacidos pretérmino y con restricción del crecimiento intrauterino (pequeños para la edad gestacional). Se observaron menores puntuaciones en hijos de madres con baja escolaridad, con síntomas de depresión, con dos o más niños menores de siete años residiendo en el domicilio y que no informaron autopercepción de apoyo/ayuda durante la gestación. Se concluye que las características potencialmente modificables (escolaridad, depresión materna y prematuridad/restricción del crecimiento intrauterino) presentaron un mayor impacto en la reducción de la puntuación de desarrollo en todos los dominios evaluados.

Resumo: O tamanho das sementes de soja é um fator que ainda necessita de estudos, pois a relação tamanho das sementes, qualidade fisiológica, estabelecimento e produtividade no campo apresenta controvérsias. Objetivou-se avaliar os efeitos do tamanho das sementes no estabelecimento da cultura da soja e na qualidade fisiológica das sementes. Em campo utilizou-se fatorial 2 x 3 x 3, sendo, duas cultivares (M 5947 IPRO e 59HO124 IPRO), três tamanhos de sementes (5.5, 6.0 e 6.5 mm) e três estandes de plantas (280.000, 320.000 e 360.000 plantas.ha-1). Foram avaliados características agronômicas e produtividade de grãos. Após a colheita, as sementes das parcelas com população de 320.000 plantas foram classificadas por tamanho utilizando-se peneiras com crivos circulares, 5.5 mm, 6.0 mm, 6.5 mm e 7.0 mm de diâmetro. Para a avaliação da qualidade fisiológica, considerou-se esquema fatorial 2 x 4, sendo, 2 cultivares e 4 tamanhos de sementes. Avaliou-se germinação, emergência em canteiro, envelhecimento acelerado, matéria seca de plântulas e índice de velocidade de emergência. Sementes menores dão origem a plantas mais baixas e com menor altura de inserção do primeiro legume. Sementes maiores apresentam maior qualidade fisiológica. A cultivar M 5947 IPRO apresentou melhores desempenho e qualidade de sementes.

Abstract: The size of soybean seeds needs further study because its relationships with physiological quality, field establishment, and yield are controversial. The aim of this study was to evaluate the effects of seed size on soybean establishment and seed physiological quality. In the field, a 2x3x3 factorial design was used, with two cultivars (M 5947 IPRO and 59HO124 IPRO), three seed sizes (5.5, 6.0, and 6.5 mm), and three sowing densities (280,000, 320,000, and 360,000 plants.ha-1). Agronomic traits and grain yield were evaluated. After harvest, only seeds from plots with a population of 320,000 plants were classified by size using circular sieves with 5.5-mm, 6.0-mm, 6.5-mm, and 7.0-mm mesh sizes. For the evaluation of physiological quality, a 2x4 factorial design was applied, with two cultivars and four seed sizes. Germination, seedling emergence, accelerated aging, seedling dry matter, and emergence speed index were evaluated. Smaller seeds gave rise to shorter plants with a lower first pod insertion height. Larger seeds had higher physiological quality. The M 5947 IPRO cultivar showed better seed performance and quality.

Abstract Background: Patients using immunosuppressive drugs may have unfavorable results after infections. However, there is a lack of information regarding COVID 19 in these patients, especially in patients with rheumatoid arthritis (RA). Therefore, the aim of this study was to evaluate the risk factors associated with COVID 19 hospitalizations in patients with RA. Methods: This multicenter, prospective cohort study is within the ReumaCoV Brazil registry and included 489 patients with RA. In this context, 269 patients who tested positive for COVID 19 were compared to 220 patients who tested negative for COVID 19 (control group). All patient data were collected from the Research Electronic Data Capture database. Results: The participants were predominantly female (90.6%) with a mean age of 53 ±12 years. Of the patients with COVID 19, 54 (20.1%) required hospitalization. After multiple adjustments, the final regression model showed that heart disease (OR =4.61, 95% CI 1.06–20.02. P < 0.001) and current use of glucocorticoids (OR =20.66, 95% CI 3.09–138. P < 0.002) were the risk factors associated with hospitalization. In addition, anosmia was associated with a lower chance of hospitalization (OR =0.26; 95% CI 0.10–0.67, P < 0.005). Conclusion: Our results demonstrated that heart disease and the use of glucocorticoids were associated with a higher number of hospital admissions for COVID 19 in patients with RA. Trial registration: Brazilian Registry of Clinical Trials RBR 33YTQC.

Resumo: Genótipos mais produtivos da cultura da soja é um dos principais objetivos dos programas de melhoramento. Existem poucos estudos quanto à seleção de caracteres associados à qualidade e desempenho de sementes de soja. Objetivou-se predizer parâmetros fisiológicos e genéticos sobre a qualidade de sementes produzidas em populações segregantes de soja, provenientes de genitores com diferentes grupos de maturidade. Foram avaliados oito genótipos da população segregante F2: 3 de soja (163, 24, 57, 108, 164, 169, 157 e 81), cultivados na safra 2018/19. Para a condução do experimento foi utilizado o delineamento inteiramente casualizado. Avaliou-se a qualidade fisiológica das sementes por meio dos testes de germinação, tetrazólio e análise de imagem. As análises estatísticas foram realizadas utilizando-se uma abordagem de modelos mistos. Foi possível observar maior vigor nas sementes dos lotes 108, 164 e 169, cujos resultados estiveram entre os melhores na maioria dos parâmetros analisados. Maior incidência de dano mecânico e por percevejos pode ser usado para explicar o menor vigor, como observado nos genótipos 57 e 163, enquanto o dano por umidade não corroborou com os testes de vigor das sementes. A resposta dos genótipos às análises realizadas indicou maior influência de características genéticas destes do que efeito do grupo de maturidade relativa. Não foi possível observar evidente efeito do grupo de maturidade relativa e o vigor das sementes de soja.

Abstract: Productive soybean genotypes is one of the main objectives of soybean breeding programs. However, there are few studies on the selection of characteristics associated with the quality and performance of soybean seeds. The objective in this study was to predict physiological and genetic parameters associated with seed quality in segregating soybean populations derived from parents of differing maturity groups. Eight genotypes of the F2:3 segregating soybean population (numbered 163, 24, 57, 108, 164, 169, 157, and 81) cultivated in the 2018/19 harvest were evaluated. To conduct the experiment, a completely randomized design was used. The physiological quality of the seeds was evaluated by germination test, tetrazolium test, and image analysis. Statistical analyses were performed by using a mixed model approach. Greater seed vigor was observed in the genotypes 108, 164, and 169, whose results were among the best for most of the analyzed parameters. The greater mechanical damage and damage due to stink bugs can explain the lower vigor of some seeds, as observed in genotypes 57 and 163, while weathering damage did not correspond to the results of the seed vigor tests. The analyses indicated a greater influence of genetic characteristics than of relative maturity group on the responses of the genotypes. No effect of relative maturity group on soybean seed vigor was evident.

Abstract Background: Rheumatic diseases are associated with an increase in overall risks of tuberculosis (TB). The aim of this study was to evaluate the frequency of TB and the frequency of latent TB infection (LTBI), in clinical practice, for juvenile idiopathic arthritis (JIA) patients from high and low risk of TB incidence endemic countries. Methods: This is an international, multicenter, cross-sectional, observational study of data collection from Brazil and Registry of Portugal at REUMA.PT. The inclusion criteria were patients with Juvenile Idiopathic Arthritis (JIA) with age ≤ 18 years who underwent screening for Mycobacterium tuberculosis infection [tuberculin skin test (TST) and/or interferon gamma release assay (IGRA)]. Chest X-rays and history of exposure to TB were also assessed. Results: 292 JIA patients were included; mean age 14.3 years, mean disease duration 7.5 years, 194 patients (66.4%) performed only TST, 14 (4.8%) only IGRA and 84 (28.8%) both. The frequency of LTBI (10.6%) and TB was similar between the two countries. The reasons for TB screening were different; in Brazil it was performed more often at JIA onset while in Portugal it was performed when starting Disease Modified Anti-Rheumatic Drugs (DMARD) treatment (p < 0.001). Isoniazid therapy was prescribed in 40 (13.7%) patients (31 with LTBI and 9 with epidemiologic risks and/or due to contact with sick people). Only three patients (1%) developed active TB. Conclusion: We found nearly 10% of patients with LTBI, a small percentage of patients with treatment due to epide-miologic risks and only 1% with active TB. Distinct reasons and screening methods for LTBI were observed between the two countries.

Abstract Since the first reported case of COVID-19 in Brazil, the public and private educational system started to close. Up to November 2020, scientific discussions about the return of schooling activities have been rarely performed by the national scientific community and police-makers. The great delay of school returning in Brazil contrasts with successful international strategies of school reopening worldwide and seems counterintuitive with the reopening of non-essential activities. Here, important issues to be considered before and during school reopening are reviewed and discussed. COVID-19 testing is essential to avoid disease spreading, but high cost of individual RT-qPCRs impairs an extensive testing strategy for school returning. To reduce costs and increase the speed of diagnosis, we tested the efficiency of a pooled-sample PCR strategy in a cohort of the educational staff in the city of Macaé/RJ, finding five asymptomatic individuals (0,66%) among the 754 people tested. Thus, a polled-sample PCR testing strategy of the educational staff might prevent infection spreading in schools at a reasonable cost. We discuss how our test strategy could be coupled with internationally recognized safety rules to allow for a safe school return and how countries from different world regions are dealing with educational activities during COVID-19 pandemic.

Abstract We have examined the mutagenic effects of the fungicide Elatus® on tadpoles of Rana catesbeiana and Leptodactylus latrans. Sixty-four tadpoles of each species have been exposed to three concentrations of Elatus® (10, 20, and 50 µg/L-1) during 96 hours. We’ve carried out the micronucleus test (MN) and erythrocyte nuclear abnormalities (ENAs) in 32 tadpoles of each species, the others 32 tadpoles of each species remained in a solution free of Elatus® during 96 hours, in order to assess the ability to recover from the damage caused by the fungicide. There was significant difference in MNs frequency between the treatment exposed to 50µg/L-1 and the control groups for R. catesbeiana, while for L. latrans, we’ve found difference between the treatment of 20 µg/L-1, followed by a period without exposure to the contaminant and the control group when all ENAs were analyzed. When we compared the two species, R. catesbeiana presented a higher frequency of MNs than L. latrans in the treatment exposed to 50 µg/L-1of the fungicide. Our findings highlight the need to monitor amphibians in places where this product is widely used.

RESUMO A família Cucurbitaceae, possui algumas espécies cujas sementes apresentam dormência, inclusive Momordica balsamina L. Esta característica obriga à utilização de métodos de quebra de dormência para aceleração do processo de germinação. Assim, objectivou-se avaliar a germinação das sementes a diferentes temperaturas após o pré-tratamento das mesmas. Utilizou-se um delineamento inteiramente casualizado, em esquema factorial 4x3 com quatro repetições de 25 sementes por modalidade, sendo quatro pré-tratamentos: remoção do tegumento; humedecimento do substrato com solução de KNO3 a 0,1%; pré-esfriamento a 10 ºC durante 3 dias e a testemunha e três temperaturas de germinação 25, 30 e 35ºC em câmaras do tipo BOD. Posteriormente procedeu-se à avaliação da primeira contagem de germinação, germinação, velocidade de emergência de plântulas e emergência de plântulas. Os resultados evidenciaram dormência tegumentar (física) das sementes. A remoção do tegumento e as temperaturas de 25 ou 30 ºC, com 97 e 96% de sementes germinadas respectivamente, proporcionaram condições ideais para germinação.

ABSTRACT The Cucurbitaceae family has some species with dormant seeds, including Momordica balsamina. Therefore, several methods have been used to overcome dormancy, as these help to accelerate the germination process. In this way, the objective was to evaluate seed germination at different temperatures after seed pre-treatments. The seed pre-treatments were: removal of the integument; wetting the substrate with 0.1% KNO3 solution; pre-cooling to 10 ºC for 3 days and control. Thereafter seeds germination temperatures were 25, 30 and 35 ºC in a BOD. Four replications of 25 seeds for each pre-treatment and temperature were used. After 21 days of the test assembly first germination count, germination, seedling emergence speed and seedling emergence were evaluated. The results showed physical seed dormancy. The removal of the tegument and the temperatures of 25 or 30 ºC, with 97 and 96% of germinated seeds respectively, provided ideal conditions for germination.
