Abstract The objective of this cross-sectional study was to investigate whether total need satisfaction and three separate basic psychological needs (autonomy, competence and relatedness) predict life skills development in dual-career athletes according to sex, type of sport, type of higher education institution and financial support. Participants included 136 Brazilian university athletes (65 boys and 71 girls) aged 17–23 years. Data collection was conducted via Basic Needs Satisfaction in Sport Scale (BNSSS) and the Life Skills Scale for Sport (LSSS). Bayesian multilevel linear regression model found that total need satisfaction and three separate basic psychological needs (autonomy, competence and relatedness) influenced life skills (teamwork, social skills, leadership, goal setting and communication) and total life skills development in dual-career athletes. Total need satisfaction influenced leadership and total life skills. Competence and relatedness influenced goal seating, social skill, leadership and total life skills. Autonomy might not have a strong correlation with life skills development dimensions standardised scores and total life skills standardised score independent of sex, type of sport, type of higher education institution and financial support. Based on such findings, satisfaction of all three basic needs combined (total need satisfaction) and separate autonomy, competence and relatedness was positively associated with the development of life skills in dual-career athletes.

ABSTRACT Purpose: to investigate genetic recurrence and molecular markers for dyslexia in two candidate genes in the Brazilian population. Methods: a cross-sectional, case-control, observational study, with five single nucleotide polymorphisms (SNPs) studied in DYX1C1 and KIAA0319 genes in 86 subjects with dyslexia and 66 controls, matched for gender and age. SNPs were genotyped using the polymerase chain reaction technique in real time, and distribution of genotypic and allelic frequencies between the groups was analyzed. Results: it was determined that 68% of the subjects with dyslexia present a family history of learning difficulties. The DYX1C1 gene did not demonstrate an association with dyslexia, which was found regarding the rs9461045 marker of the KIAA0319 gene. Conclusion: a family history of learning problems was present in more than two-thirds of the group with dyslexia, indicating that this is an important risk factor. An association with dyslexia in the rs9461045 marker was noted, making the study the first one to show an association of the KIAA0319 gene with dyslexia, in Latin America.

Abstract This study examined how basic psychological needs satisfaction can predict youth participants’ life skills development according to gender and sport type. A sample of 461 Brazilian youth sport participants (325 boys and 136 girls) ranging between 10 and 17 years was included. Data collection was conducted through the Life Skills Scale for Sport and Basic Needs Satisfaction in Sport Scale. Overall, the three subscales of basic psychological needs satisfaction explained a significant amount of the variance in eight life skills (R2 range = .02 to .08 p < .05) and total life skills (R2 = .07; p < .001) in male athletes. Concerning female athletes, multiple regression analyses revealed significant variance only for teamwork (R2=.09; p<.01) and goal setting (R2= .06; p<.05). Regarding the type of sport, the model presented a significant amount of the variance in eight life skills (R2 range = .02 to .05 p < .05) and total life skills (R2 = .08; p < .001) in team sports. Lastly, in individual sports, multiple regression analyses revealed significant variance only on goal setting (R2= .04; p<.05). Findings showed that youth sport coaches could focus on youth participants’ basic psychological needs when trying to foster life skills development across sport contexts. Based on these findings, several suggestions for improving future research and practice in this area are presented.

Resumo Este estudo examinou como a satisfação das necessidades psicológicas básicas pode prever o desenvolvimento de competências para a vida dos jovens participantes de acordo com o género e o tipo de desporto. Foi incluída uma amostra de 461 atletas juvenis brasileiros (325 meninos e 136 meninas) com idades entre 10 e 17 anos. A coleta de dados foi realizada por meio da Escala de Habilidades para a Vida no Esporte e da Escala de Satisfação de Necessidades Psicológicas Básicas no Esporte. No geral, as três subescalas de satisfação de necessidades psicológicas básicas explicaram uma quantidade significativa da variância em oito habilidades para a vida (faixa R2 = 0,02 a 0,08 p < 0,05) e habilidades para a vida totais (R2 = 0,07; p < 0,001) em atletas masculinos. Em relação às atletas femininas, as análises de regressão múltipla revelaram variância significativa apenas para trabalho em equipe (R2=0,09; p<0,01) e estabelecimento de metas (R2= 0,06; p<0,05). Em relação ao tipo de esporte, o modelo apresentou uma quantidade significativa de variância em oito habilidades para a vida (faixa R2 = 0,02 a 0,05 p < 0,05) e habilidades para a vida totais (R2 = 0,08; p < 0,001) em equipes. Esportes. Por último, nos desportos individuais, as análises de regressão múltipla revelaram variância significativa apenas no estabelecimento de metas (R2= 0,04; p<0,05). Os resultados mostraram que os treinadores desportivos juvenis podem concentrar-se nas necessidades psicológicas básicas dos jovens participantes ao tentarem promover o desenvolvimento de competências para a vida em contextos desportivos. Com base nestas conclusões, são apresentadas uma série de sugestões para melhorar futuras pesquisas e práticas nesta área.

The acquired immunodeficiency syndrome (AIDS) is a disease which effects the immune system and, to reduce the development of this pathology, antiretrovirals was created. Evidences demonstrate the effectiveness of Pre-Exposure Prophylaxis (PrEP), however, it still has obstacles, such as the lack of knowledge, technique and training of health professionals for patient guidance and prescription. The aim of this research is to investigate the subjective and objective knowledge of PrEP, futhermore the number of prescriptions in State of Goiás. For data collection, a survey was applied to 152 physicians with active enrollment in Conselho Regional de Medicina do Estado de Goiás. As a result, 132 physicians (86,8%) reported having previous knowledge about PrEP, on average of 44,2% informed having knowledge for prescription, 129 (84,8%) never prescribed PrEP and, when objectively evaluated, on average of 83,8% have knowledge about the risk categorization for the drug use. The outcome of this research is not consonant with the hypothesis that only 20% of the physicians would have plenty knowledge, according to the literature, but it is evident the need for medical training to optimize the clinical impact on public health of this important HIV prevention strategy.

A Síndrome da Imunodeficiência Adquirida é uma infecção que acomete o sistema imunológico e, para redução da propagação dessa patologia, desenvolveu-se os antirretrovirais. Evidências demonstram a eficácia da Profilaxia Pré-Exposição (PrEP), mas ainda com obstáculos, como a falta de conhecimento, técnica e treinamento dos profissionais de saúde para a sua orientação e prescrição. O objetivo dessa pesquisa é investigar o conhecimento subjetivo, objetivo e prescrição da PrEP por médicos do Estado de Goiás. Para a coleta de dados foi aplicado um questionário à 152 médicos com inscrição ativa no Conselho Regional de Medicina do Estado de Goiás. Como resultado, 132 médicos (86,8%) afirmaram possuir conhecimento prévio sobre a PrEP, em média 44,2% informaram ter conhecimento para prescrição, 129 (84,8%) nunca prescreveram PrEP e, quando avaliado objetivamente, em média 83,8% possuem conhecimento sobre a categorização de risco para o uso do medicamento. Os resultados dessa pesquisa não estão em consonância com a hipótese de que apenas 20% dos médicos teriam conhecimento suficiente, de acordo com a literatura, mas é evidente a necessidade de capacitação médica visando otimizar o impacto clínico na saúde pública desta importante estratégia de prevenção do HIV.

ABSTRACT Background: Neotropical species lack autecological information. Among these, are phenological studies, which help to understand forest dynamics and provide important contributions to the collection, restoration, and conservation programs. This research aimed to characterize the vegetative and reproductive phenological behavior of neotropical species Geoffroea spinosa Jacq. in a seasonally dry tropical forest, as well as to verify if there is a correlation between phenophases and environmental parameters. Twenty individuals were accompanied monthly for two years, to detect and tally the presence of floral buds, flowers, immature fruits, ripe fruits, leaf emergence, presence of mature leaves, and defoliation. A semi-quantitative evaluation was carried out with the Fournier method. Results: The results showed that the population had synchrony of reproductive events, with more than 50% of the individuals blooming and fruiting during the same time interval. Furthermore, the circular statistical test indicated a high seasonality for reproductive events (r ≥ 0.50 and p < 0.001). Among the vegetative events, all were classified as non-seasonal (r < 0.5). G. spinosa, showed a significant correlation (p ≤ 0.05) for all meteorological variables evaluated. Conclusion: The reproductive phenophases of G. spinosa showed strongly seasonal behavior, unlike vegetative events. the period between mid-February and the end of March was the most propitious for fruit collection. No seasonality was observed for the vegetative events. The species proved to be sensitive to El niño conditions. Follow-up phenological studies associated with meteorological variables are important for a better understanding of the dynamics of vegetative behavior in response to climate change.

Resumo Introdução: a avulsão de dentes decíduos é um evento perturbador e inesperado. Descrição: o presente relato descreve o caso clínico de uma criança de três anos que sofreu avulsão e reimplante dos incisivos centrais superiores decíduos no local do acidente. Os responsáveis procuraram atendimento para a criança na Universidade Federal de Minas Gerais após reimplante. Quatro meses depois, a criança sofreu novo trauma e os dentes reimplantados apresentavam mobilidade avançada, reabsorção radicular e fístula. A conduta clínica foi extração e reabilitação com mantenedor estético fixo. Discussão: a literatura descreve duas opções de tratamento para avulsão de incisivos decíduos: o reimplante e o não reimplante. De acordo com revisão sistemática recente, a dificuldade de se obter um consenso sobre a melhor conduta clínica se deve, em parte, à escassez de publicações que apresentem não apenas acompanhamentos com sucesso clínico, mas também com falhas. O reimplante pode ser influenciado por vários fatores. O tempo decorrido entre o reimplante e a contenção, e o novo episódio de trauma, influenciaram negativamente o prognóstico do presente caso, levando ao insucesso. O reimplante de incisivos decí- duos ainda não é um tratamento baseado em evidências. Portanto, essa opção deve ser escolhida com cautela e em situações ideais. Requer monitoramento clínico e radiográfico para constante avaliação do desfecho.

Abstract Introduction: the avulsion of primary teeth is a disturbing and unexpected event. Description: this report describes the clinical case of a three-year-old child who suffered an avulsion and replantation of the primary upper central incisors at the site of the injury. The guardians sought treatment for the child at the Federal University of Minas Gerais after the replantation. Four months later, the child suffered a new trauma and the replanted teeth presented advanced mobility, root resorption and fistula. The clinical conduct was extraction and rehabilitation with a fixed esthetic maintainer. Discussion: the literature describes two treatment options for avulsion of primary incisors: replantation and non-replantation. According to a recent systematic review, the difficulty in obtaining a consensus regarding the best clinical conduct is due, in part, to the scarcity of publications that present not only follow-ups with clinical success, but also with failures. The outcomes of replantation can be influenced by several factors. The time elapsed between replantation and splinting, and the new episode of trauma, negatively influenced the prognosis in the present case, leading to failure. Replantation of primary incisors is not yet evidence-based treatment. Therefore, this option must be chosen with caution and in ideal situations. It requires constant clinical and radiographic monitoring for evaluation of outcomes.

RESUMO O estudo objetivou analisar a associação entre a posição da atacante, o local do lançamento e a direção do lançamento com o efeito do lançamento, bem como os fatores preditivos deste. Foram analisadas 6146 ações de ataque de 66 jogos realizados pelas 24 equipes participantes do Campeonato Mundial de Handebol Feminino de 2015. Para a associação entre as variáveis estudadas recorreu-se ao teste do Qui-Quadrado e para análise preditiva utilizou-se à regressão logística multinomial. Adotou-se o valor de significância de p≤0,05 e utilizou-se o software SPSS versão 20.0 para Windows. Os resultados apontaram associação entre o efeito do lançamento e a posição da atacante (��2= 107,39; p=0,0001; ɸ=0,13), entre o efeito do lançamento e o local do lançamento (��2= 715,01; p=0,0001; ɸ=0,34), entre o efeito do lançamento e a direção do lançamento (��2= 587,25; p=0,0001; ɸ=0,34) e que o local do lançamento e a direção do lançamento foram fatores preditivos do efeito do lançamento (��2=854,666; p<0,0001). Assim, a partir dos resultados, pode-se concluir que o efeito do lançamento é predito pelo local do lançamento e pela direção do lançamento, sugerindo que a posição da jogadora não influencia na obtenção do gol.

ABSTRACT The study aimed to analyze the association between the position of the attacker, the place of the finish and the direction of the finalization with the effectiveness of the finalization, as well as the predictive factors of this. A total of 6146 attack actions of 66 matches were analyzed by the 24 teams participating in the 2015 Women’s World Handball Championship. For the association between the variables studied, we used the Chi-Square test and for predictive analysis of the data, we used the multinomial regression. The significance level of p≤0.05 was adopted and the software SPSS version 20.0 for Windows was used. The results showed an association between the finalization effect and the attacker’s position (χ2 = 107.39, p = 0.0001, ɸ = 0.13), association between the finishing effect and the finishing direction (χ2 = 715, (Χ2 = 587.25, p = 0.0001, ɸ = 0.34), and that the predictive factors of the finalization effect was statistically significant (χ2 = 854.666; p <0.0001). Thus, from the results, it is possible to concluded that the effect of the finalization and the direction of the finalization, suggesting that the position of the player does not influence in obtaining the goal.

BACKGROUND Fibrosis in the peripheral nerve is the end stage of leprous neuropathy and the cause of the resulting permanent neural function impairments. Preventive measures to avoid this irreversible pathological state are a relief strategy for leprosy sufferers. OBJECTIVES The present study describes the frequency of fibrosis along with its characterisation and pathogenic development. METHODS Six-hundred-and-thirteen nerve samples were sorted from 278 neural leprosy (NL) and 335 non-leprosy neuropathy patients (ON). The total number of samples was histologically examined by routine staining methods (haematoxylin-eosin, Wade staining and Gomori’s trichrome) and fibrosis was evaluated via semi-quantitative estimation. FINDINGS Fibrosis was most frequent in the NL group (33% against 0.4% in ON) while fibrosis in association with endoneurial microfasciculation was found in 38 (41.3%) of the NL samples in the examination of semithin sections. Pericytic activation in the perivascular environment was confirmed to be the source of the fibroblasts and perineurial cells delimiting microfascicles. End-stage fibrosis in leprosy displays an arrangement of microfascicles devoid of neural components (i.e., Schwann cells and axons) lined by an intermediate phenotype of fibroblastic-perineurial cells filled with bundles of collagen fibres. MAIN CONCLUSIONS The present study underscores that fibrosis is frequently the severe end stage of neural leprosy NL pathogeny after analysing the notably distinct development of fibrosis within the neural environment.

Resumo O objetivo deste artigo é descrever a percepção sobre quedas dos idosos residentes na comunidade; mensurar a exposição desses indivíduos a fatores de risco domiciliares relacionados; e avaliar a influência do conhecimento sobre queda na adoção de medidas preventivas. O questionário FRAQ-Brasil foi aplicado a 473 idosos, juntamente com um questionário sobre exposição a 20 fatores de risco domiciliares. Associações entre as variáveis foram analisadas utilizando o teste qui-quadrado com intervalo de confiança de 95%. A idade variou de 60 a 95 anos, com média de 70,6 anos; os entrevistados foram principalmente do sexo feminino (58,4%), e renda de 2 salários mínimos (46,3%); a média de acertos no questionário FRAQ-Brasil foi de 19,5 em até 32 pontos e os idosos entrevistados estavam expostos, em média, a 7,8 fatores de risco domiciliares; 180 idosos disseram já terem recebido informações sobre queda. A maioria da população idosa apresenta pouco conhecimento sobre queda. Indivíduos com idade mais avançada e com maior conhecimento sobre queda estão expostos a menos fatores de risco domiciliares, possivelmente pela maior adoção de medidas preventivas através da modificação do ambiente doméstico.

Abstract Objectives: to describe the awareness about falls among elderly people living in their households in communities, to measure the other risks that they are exposed to in their homes and to evaluate the influence that knowledge on falling brings in the adoption of preventative measures. Method: The FRAQ-Brazil questionnaire was used on 473 elderly people as well as a questionnaire on elderly people being exposed to 20 household risk factors. Associations between the variables were analyzed using the chi-squared test with a confidence interval of 95%. Results: The age range was between 60 and 95 years with the average being 70.6 years. The majority of those interviewed were female (58.4%) who were earning 2 minimum wages (46.3%). The average amount of correct answers given with the use of the FRAQ-Brazil questionnaire was 19.5 out of 32 points and the elderly participants were, on average, exposed to 7.8 household risk factors. 180 of them stated that they had already received information on falls. Conclusion: The majority of the elderly population displayed little knowledge on falls and were exposed to a variety of daily risk factors. Individuals who were more advanced in years and who had more knowledge on falls, were exposed to less household risk factors. This may well have been due to the adoption of preventative measures through changing domestic environment.

RESUMO: Bactérias da espécie Aeromonas hydrophila são patógenos que atacam peixes, causando grandes prejuízos à piscicultura. Entender os perfis de resistência dessa bactéria e a capacidade da mesma em transferir tal resistência é importante para implantação de um manejo adequado na produção de peixes. Os objetivos desse estudo foram analisar a resistência de isolados de Aeromonas hydrophila à antimicrobianos e metais pesados e, correlacionar os perfis encontrados com a presença de plasmídeos. A resistência dos isolados aos antimicrobianos (oxacilina, gentamicina, tetraciclina e ácido nalidíxico) e metais pesados (cádmio, chumbo, cobre e manganês) foi verificada pelas técnicas da Concentração Bactericida Mínima (CBM) e Concentração Inibitória Mínima (CIM). Foi calculado o Índice de Resistência Múltipla aos Antimicrobianos (IRMA). Os plasmídeos foram extraídos por metodologias descritas pela literatura. A relação entre a resistência aos antimicrobianos e metais pesados com a presença de plasmídeos foi determinada pelo teste de Mann-Whitney utilizando o ambiente R. Foi observada alta resistência aos antimicrobianos e metais pesados testados, com exceção à gentamicina e cádmio. No IRMA os isolados apresentaram resistência a todos os perfis de antimicrobianos possíveis. Quatorze isolados apresentaram plasmídeos, mas não foi encontrada relação dos perfis de resistência com a presença destes, o que indica que os genes de resistência a esses compostos estejam presentes no DNA cromossômico. Porém apontam a possibilidade de transferência dos genes de resistência entre os isolados. Estes resultados apontam alta resistência dos isolados e capacidade de transmissão dessa resistência a outras bactérias. A resistência aos metais pesados, pode estar ligada ao uso de fertilizantes nas plantações localizadas próximas as margens do Rio São Francisco.

ABSTRACT: Aeromonas hydrophila is a common fish pathogen that causes extensive damage to aquaculture. To develop and implement a more adequate strategy to farm fish, it is crucial to understand the bacterial-resistance levels and their transference dynamics. The objective of this study was to analyze the resistance profile of isolated Aeromonas hydrophila to antimicrobial agents and heavy metals and draw a correlation of the observed profiles with the presence of plasmids. Resistance of the isolated bacteria to antimicrobial agents (oxacilin, gentamicin, tetracycline, and nalidixic acid) and heavy metals (cadmium, lead, copper, and manganese) was verified using the minimum bactericidal concentration (MBC) and minimum inhibitory concentration (MIC) standards. The Multiple Antibiotic Resistance Index (MAR Index) was calculated. Plasmids were extracted by using a common methodology described elsewhere. Mann-Whitney Test, implemented in the R environment, was used to determine the correlation between resistance and plasmids presence. A high resistance to almost all antimicrobial agents and heavy metals was observed, except to gentamicin and cadmium. The MAR index results showed resistance to all antimicrobial profiles. Of the isolated bacteria, 14 showed the presence of plasmids. However, no correlation was noted between the resistance profile and the plasmid presence for these isolates, indicating that the genes responsible for resistance to microbial agents and heavy metals are present in the cromossomic DNA, which in turn suggested the possibility of gene transfer between the isolated bacteria. The resistance to heavy metals can be linked to heavy utilization of fertilizers along the Sao Francisco River.

Resumo O objetivo deste estudo foi identificar o efeito do ataque das posições 1 e 6 no voleibol masculino brasileiro de alto nível, no intuito de compreender melhor a estruturação ofensiva do jogo. A amostra constituiu-se pela observação de 142 jogos da Superliga Masculina 2014-2015, totalizando 2969 ações de recepção, levantamento e ataque das posições 1 e 6. Os resultados mostraram que houve associação entre o local do ataque, o tempo de ataque, o tipo de ataque e o efeito do ataque (p<0,001). Os resultados mostraram que o ponto de ataque, quando o mesmo é realizado a partir da posição 6, associa-se ao ataque na paralela, enquanto, ao analisar a posição 1, o ponto de ataque associa-se ao ataque potente na diagonal. Além disso, o ataque colocado associou-se à continuidade do jogo, assim como as recepções de baixa qualidade (b e c). Neste contexto, conclui-se que a posição do atacante influencia na eficácia do ataque utilizado, segundo o tempo de ataque e o tipo de ataque.

Abstract The aim of this study was to identify the effect of attacks from positions 1 and 6 in high-level Brazilian Men’s Volleyball in order to understand the offensive structure of the game. The sample was composed of the observation of 142 2014-2015 Men’s Superleague games, totaling 2969 reception, set and attack actions from positions 1 and 6. The results showed association between place of attack, attack tempo, type of attack and effect of attack (p<0.001). The results showed that the point of attack, when it is performed from position 6, is associated with parallel attack, while, when analyzing position 1, the point of attack is associated with potent diagonal attack. Furthermore, placed attack was associated with game continuity, as well as with low-quality receptions (b and c). In this context, it was concluded the attacking position influences the attack efficacy, according to time and type of attack.

RESUMO Espécies de Botryosphaeriaceae são importantes patógenos em diversas plantas lenhosas e não lenhosas, causando diferentes tipos de sintomas. Espécies desta família são usualmente consideradas patógenos fracos, causando doenças apenas quando estas plantas se encontram sob algum tipo de estresse como seca, temperaturas baixas ou elevadas, deficiência nutricional e danos causados por outros patógenos ou pragas. No entanto, pouco se conhece sobre a ocorrência e diversidade de espécies de Botryosphaeriaceae em plantas nativas do bioma Caatinga, localizado no Semiárido, e sobre a presença de fungos endofíticos nessas espécies, e muito menos sobre a sua importância como patógenos. O objetivo do presente estudo foi avaliar a patogenicidade de 74 isolados representando as espécies Botryosphaeria mamane, Pseudofusicoccum adansoniae, P. stromaticum, o complexo Neofusicoccum parvum/ribis, Lasiodiplodia gonubiensis e L. theobromae, identificados pela primeira vez como endofíticos em plantas típicas do bioma Caatinga. Testes de patogenicidade conduzidos em frutos de mangueira e ramos de plantas adultas de Spondias sp., revelaram que todas as espécies de Botryosphaeriaceae desse estudo foram patogênicas, sendo L. theobromae e o complexo N. parvum/ribis as mais agressivas. Este é o primeiro relato sobre fungos endofiticos em plantas do bioma Caatinga cearense, bem como a confirmação de que estas espécies podem atuar como fonte de inóculo para espécies de frutíferas comerciais da região do Semiárido brasileiro.

ABSTRACT Species of the Botryosphaeriaceae are important pathogens in several woody and non-woody plants, causing different types of symptoms. Species of this family are usually regarded as weak pathogens, only causing diseases when plants are under some type of stress such as drought, hot or cold weather, poor nutrition and damage caused by other pathogens or pests. However, little is known about the occurrence and diversity of Botryosphaeriaceae species in native plants of the biome Caatinga, located in the Brazilian Semi-Arid Region, and about the presence of endophytic fungi in these species; even less is known about their importance as pathogens. The aim of the present study was to assess the pathogenicity of 74 isolates representing the species Botyosphaeria mamane, Pseudofusicoccum adansoniae, P. stromaticum, the complex Neofusicoccum parvum/ribis, Lasiodiplodia gonubiensis and L.theobromae, identified for the first time as endophytic in plants typical of the biome Caatinga. Pathogenicity tests conducted in mango fruits and branches of adult plants of Spondias sp. revealed that all Botryosphaeriaceous species of this study were pathogenic, and L. theobromae and the complex N.parvum/ribis were the most aggressive ones. This is the first report of such endophytic fungi in plants of the biome Caatinga in Ceará State, as well as the confirmation that these species can act as a source of inoculum for commercial fruit species of the Brazilian Semi-Arid Region.

Este trabalho foi realizado com o objetivo de avaliar o efeito de diferentes níveis de salinidade da água de irrigação e tratamento de sementes com regulador vegetal no desenvolvimento do algodoeiro. O delineamento experimental adotado foi inteiramente ao acaso, arranjados em esquema fatorial 5 x 2 com quatro repetições. Os tratamentos resultaram da combinação de cinco níveis de salinidade da água de irrigação (S1-0,5; S2-2,0; S3-3,5; S4-5,0 e 6,5 dS m-1) em sementes tratadas e não tratadas com regulador vegetal. As características avaliadas foram: número de folhas, área foliar, altura, massa seca do caule, das folhas e da parte vegetativa, área foliar específica e razão de área foliar. Houve interação entre salinidade e tratamentos de sementes com cloreto de mepiquat apenas para área foliar e razão de área foliar. Todas as demais características foram reduzidas com o aumento da salinidade da água de irrigação, com maiores reduções para área foliar (média de 65,8%) e massa seca da parte vegetativa (64%). O tratamento das sementes com cloreto de mepiquat afetou o desenvolvimento das plantas, independente da salinidade.

This work was carried out to evaluate the effect of irrigation water at different salinity levels, and of seed treatment with plant growth regulator, on the development of the cotton plant. The experimental design used was completely randomized, arranged in a 5 x 2 factorial scheme with four replications. The treatments resulted from the combinations of five levels of salinity of the irrigation water (S1-0.5, S2-2.0, S3-3.5, S4-5.0 and 6.5 dS m-1) on seeds, both treated and not treated with growth regulator. The evaluated characteristics were: number of leaves, leaf area, height, dry mass of stems, leaves and vegetative parts, specific leaf area and leaf area ratio. There was an interaction between salinity and seed treatments with mepiquat chloride, but only for leaf area and leaf area ratio. All other characteristics decreased with the increasing salinity of the irrigation water, with greater reductions in leaf area (mean of 65.8%) and dry mass of vegetative parts (64%). Seed treatment with mepiquat chloride affected plant development, independent of salinity.
