ABSTRACT Accurate wood volume predictions are critical in hyperdiverse forests because each species has specific size and shape traits. Although generic models at a multispecies level were widely used in Amazonian managed forests, they are subject to more significant bias due to interspecific variability. We used an extensive database of wood volume collected in managed forests to test the hypothesis that generic models violate the independence assumption due to that predictions vary with species-specific size. Our hypothesis was proved as residuals of the generic model were conditioned to species and specific size. The multilevel models were more accurate both in fitting and validation procedures, and accounted for variance derived from species and specific size, providing a more reliable prediction. However, we found that the size-specific models have a similar predictive ability to species-specific models for new predictions. This implies more practical estimates in hyperdiverse forests where fitting species-specific models can be complex. The findings are crucial for sustainable forest management as they allow for more reliable wood volume estimates, leading to less financial uncertainty and preventing damage to forest stocks through under or over-exploitation.

RESUMO Previsões precisas do volume de madeira são críticas em florestas hiperdiversas, pois cada espécie tem características específicas de tamanho e forma. Embora modelos genéricos em nível multiespécie sejam amplamente utilizados em florestas manejadas na Amazônia, eles estão sujeitos a maiores vieses devido à variabilidade interespecífica. Usamos um extenso banco de dados de volume de madeira coletado em florestas manejadas para testar a hipótese de que modelos genéricos violam a suposição de independência, pois as previsões variam de acordo com o tamanho específico da espécie. Nossa hipótese foi comprovada pois os resíduos do modelo genérico foram condicionados à espécie e ao tamanho específico. Os modelos multiníveis foram mais precisos nos procedimentos de ajuste e de validação e contabilizaram a variância derivada de espécies e do tamanho específico, fornecendo previsões mais confiáveis. Descobrimos que os modelos específicos de tamanho têm capacidade preditiva semelhante aos específicos da espécie para novas previsões. Isto implica em estimativas mais práticas em florestas hiperdiversas, onde pode ser complexo o ajuste de modelos específicos por espécies. As conclusões são cruciais para o manejo florestal sustentável, pois permitem estimativas mais confiáveis do volume de madeira, conduzindo a menor incerteza financeira e evitando danos aos estoques florestais devido à sub ou superexploração.

Abstract Land-use changes followed by inadequate management may cause serious impacts to springs, generating losses in quality and availability. An alternative to minimize or mitigate potential future impacts is to monitor the water quality parameters of micro-watersheds in the medium- and long-term. This monitoring is essential for planning purposes and governmental environmental regulation, especially in highly altered regions in the Amazon, such as Paragominas, in the state of Pará. This study investigated the influence of land use change and seasonality on the quality of springs. For this purpose, physicochemical parameters characteristic of water quality in five collection points of springs with a surrounding area of distinct land use history were analyzed between 2015 and 2017. Following the current legislation, the only parameter in imbalance was dissolved oxygen (DO). However, these are common values, considering springs. The results showed that most of the parameters presented variation to different land uses. This interpretation was intensified mainly by the variations in Sodium, TN, DO and temperature. However, few of these variables were related to local seasonality (only turbidity, sulfate and potassium). These results prove that it is possible to integrate the change in the use and occupation of the basin, determined by the variations observed in the sampled points. Thus, studies and diagnostics that can subsidize management in basin areas are an important tool to direct public policies to improve environmental and social quality for the population living around these basins.

Resumo Mudanças de uso da terra seguido de manejo inadequado podem causar sérios impactos a nascentes, gerando prejuízos na qualidade e disponibilidade. Uma alternativa para minimizar ou mitigar impactos potenciais futuros é monitorar a médio e longo prazo os parâmetros de qualidade da água de microbacias. Este acompanhamento é essencial para fins de planejamento e regulamentação ambiental governamental, principalmente em regiões na Amazônia altamente alteradas, como em Paragominas, no estado do Pará. O objetivo deste estudo foi investigar a influência da mudança de uso da terra e da sazonalidade na qualidade de nascentes. Para isso, parâmetros físico-químicos característicos de qualidade da água em cinco pontos de coleta de nascentes com área circundante de histórico de uso da terra distintos foram analisadas entre 2015 e 2017. Seguindo a legislação vigente, o único parâmetro em equilíbrio foi o oxigênio consumido (OD). Entretanto, estes são valores comuns, considerando para nascentes. Os resultados mostraram que a maioria dos parâmetros apresentou variação em relação aos distintos usos da terra. Esta interpretação foi intensificada principalmente pelas variações encontradas em Sódio, NT, OD e temperatura. No entanto, poucas dessas variáveis foram relacionadas à sazonalidade local (apenas turbidez, sulfato e potássio). Estes resultados comprovam que é possível integrar a mudança no uso e ocupação da bacia, determinadas pelas variações observadas nos pontos amostrados. Assim, estudos e diagnósticos que possam subsidiar a gestão em áreas de bacias constituem importante ferramenta para direcionar políticas públicas de melhoria da qualidade ambiental e social para a população que vive no entorno destas bacias.

PERFLUORINATED COMPOUNDS: A THREAT TO THE CLEAN OCEAN. Per- and polyfluorinated compounds (PFAS) have been produced for more than seven decades and widely used in the most diverse areas, from food packaging, textile industry, aqueous film-forming foam to pesticides and surfactants. However, the characteristics that allow the wide range of applications also bring environmental concerns due to their persistence and toxic effects. Although the ocean might be the final destination of PFAS, in Brazil few studies have been carried out about PFAS and there are many gaps regarding their environmental occurrence, sources and distribution. Therefore, this article presents a review of the production, use, behavior in the environment, legislation, the occurrence of classic PFAS in the Brazilian marine environment, as well as perceptions about their fluorinated substitutes.

Resumo Objetivo Avaliar a possibilidade de maiores graus de degeneração discal levarem a maiores dor e disfunção. Métodos Exames de imagem por ressonância magnética (IRM) de 85 pacientes com lombalgia idiopática por mais de 12 semanas foram avaliados, sendo quantificado o grau de degeneração discal de acordo com a escala de Pfirrmann. O grau de Pfirrmann em cada espaço discal de L1-L2 a L5-S1, o grau máximo de Pfirrmann (Pfirrmann-max) entre os discos lombares, e a soma dos graus de Pfirrmann (Pfirrmann-soma) foram correlacionados (por meio do teste de Spearman) com o Índice de Incapacidade de Oswestry (IIO) e a escala visual analógica (EVA) de dor. Resultados No total, 87% dos pacientes tinha degeneração discal moderada ou acentuada medida pelo Pfirrmann-max, sendo L4-L5 e L5-S1 os discos mais degenerados. Houve uma correlação de fraca a moderada entre o Pfirrmann-max (r ¼ 0,330; p¼ 0.002) e a Pfirrmann-soma (r ¼ 0,266; p¼ 0,037) e o IIO, e entre o grau de Pfirrmann em L1-L2 e o IIO e a EVA. Conclusão A degeneração discal lombar moderada ou acentuada é frequente em indivíduos com lombalgia crônica idiopática, e tem um impacto negativo na qualidade de vida dos pacientes. Pequenos graus de degeneração discal em L1-L2 podem determinar maior grau de dor e maior incapacidade funcional.

Abstract Objective To access the possibility that higher degrees of disc degeneration lead to higher levels of pain and dysfunction. Methods Magnetic resonance imaging (MRI) scans of 85 patients with low back pain lasting for more than 12 weeks were evaluated, and the degree of disc degeneration was quantified according to the Pfirrmann grading system. The Pfirrmann degree in each disc space from L1-L2 to L5-S1, the maximum degree of Pfirrmann (Pfirrmannmax) between the lumbar discs, and the sum of Pfirrmann (Pfirrmann-sum) degrees were correlated (through the Spearman test) with the Oswestry Disability Index (ODI) and the Visual Analogical Scale (VAS) for pain. Results In total, 87% of the patients had moderate to severe lumbar disc degeneration measured by Pfirrmann-max, and the most degenerated discs were L4-L5 and L5S1. There was a week to moderate correlation regarding the Pfirrmann-max (r ¼ 0,330; p¼ 0.002) and the Pfirrmann-sum (r ¼ 0,266; p¼ 0,037) and the ODI, and the Pfirrmann scores in L1-L2 were correlated with the ODI and the VAS. Conclusion Patients with chronic idiopathic low back pain frequently have moderate to severe lumbar disc degeneration, which has a negative impact on the quality of life of the patients. Low degrees of degeneration in L1-L2 might be related with higher degrees of pain and of functional disability.

Resumo O artigo analisa a emergência de um novo tipo de empresa agrícola no território brasileiro: as imobiliárias agrícolas financeirizadas. Para ser caracterizadas como tais, além de controladas pelo capital financeiro, as empresas precisam considerar a terra um ativo financeiro, isto é, o modelo de gerenciamento da propriedade deve ser determinado pela expectativa dos investidores de obterem rendimentos iguais ou superiores às demais formas de investimento nos mercados especulativos. Além de propor uma tipologia dessas empresas, o artigo apresenta o ciclo de precificação das terras. Dados e informações foram obtidos em trabalhos de campo (entre 2014 e 2019), com visitas às empresas e entrevistas com funcionários, gerentes e diretores, assim como em jornais e revistas, artigos científicos e relatórios institucionais. Os exemplos analisados aqui mostram uma das expressões do land grabbing no território brasileiro, enfatizando a metamorfose da relação entre o capital financeiro e o mercado fundiário.

Abstract The article analyzes the emergence of a new type of agricultural company in Brazil: Farmland real estate investment financial companies. To be characterized as such, besides being controlled by financial capital the companies need to consider land as a financial asset, that is, the property management model should be determined by investors’ expectations of obtaining returns equal to or higher than other forms of investment in speculative markets. Thus, besides proposing a typology of these companies, the paper also presents the pricing of land. The data and information were obtained in fieldwork (between 2014 and 2019) with visits to the companies and interviews with employees, managers, and directors, and in specialized newspapers and magazines, scientific articles, and institutional reports. The examples analyzed in this article demonstrate one of the expressions of land grabbing in the Brazilian territory by emphasizing the metamorphosis of the relationship between financial capital and the land market.

RESUMO Esta pesquisa problematiza significados atribuídos pela produção de conhecimento sobre deficiências e Educação Física escolar em 14 periódicos, entre o período de 1979 e 2019. Trata-se de uma investigação de abordagem quanti-qualitativa, que se sustenta na correlação de fontes bibliográficas e documentais. No contexto amplo identificou-se 325 publicações, das quais 113 enfocam o contexto escolar e estabelecem interfaces entre a Surdez e as Deficiências Física, Visual e Intelectual, além de uma forte vertente de discussão sobre deficiência no sentido geral, na qual exalta-se as temáticas da formação de professores e da inclusão. Conclui-se, ainda que tais temáticas sejam vislumbradas, importa o fomento de mais investigações as envolvendo.

ABSTRACT This research problematizes the meanings attributed by the production of knowledge about disabilities and School Physical Education in 14 journals, between the period of 1979 and 2019. This is an investigation with a quantitative-qualitative approach, which is based on the correlation of bibliographic and documentary sources. In the broad context, 325 publications were identified, of which 113 focus on the school context and establish interfaces between Deafness and Physical, Visual and Intellectual Disabilities, in addition to a strong aspect of discussion about disability in the general sense, in which the themes of teacher formation and inclusion are exalted. It is concluded, even if such themes are glimpsed, it is important to encourage further investigations involving them.

ABSTRACT. The forage palm is widely cultivated in semiarid regions. It has a basic chromosome number of x = 11 and polyploids are the main variation. It is propagated via vegetative reproduction, and sexual propagation is rarely used. The objective was to associate the physiological quality of seeds of different cultivars of forage palm with the level of ploidy in the genera Opuntia and Nopalea. The cultivars used were: diploids (2n = 22) ‘F8’, ‘F21’, and ‘IPA Sertânia’; tetraploids (2n = 44) ‘Clone 6 African Elephant Ear’, ‘Mexican Elephant Ear’, and ‘V19’, and octaploids (2n = 88) ‘Round’, ‘Giant’, and ‘IPA Clone 20’. Thousand seed weight, length, diameter, number of seeds per fruit, first count and emergence percentage, shoot and root length, fresh and dry mass, electrical conductivity, and length, width, and fresh and dry weight of cladodes were measured. A nested scheme design was used, with three levels of ploidy and three cultivars within each level. The ploidy level positively influenced the number of seeds per fruit and the physiological quality of the seeds. Cultivars behave differently within the same ploidy level.

RESUMO O presente artigo tem por objetivo discutir o nascimento da moderna teoria literária, considerando a Escola Formal como ponto de partida da constituição dos estudos literários como disciplina autônoma. Os primeiros movimentos dos teóricos do Formalismo buscaram compor um corpo conceitual próprio e entender o fenômeno literário como algo emancipado de categorias da sociologia, da filosofia ou da psicologia. Tal esforço produziu resultados originais, mas também gerou impasses que estão na base da crise da teoria literária nos anos 1970 e 1980, momento em que emergem as chamadas pós-teorias, que trouxeram para o centro das atenções elementos extra-literários (gênero, política, perspectiva decolonial). Este artigo argumenta que tais impasses se tornaram evidentes já nos primeiros momentos da Escola Formal, quando ela precisou confrontar sua construção teórica com a prática da crítica literária. Ambas as esferas, ao mesmo tempo em que se retroalimentam, explicitavam as deficiências e limites de cada uma.

ABSTRACT The present paper aims at discussing the birth of modern literary theory, taking the Formal School as the starting point of the constitution of literary studies as an autonomous discipline. Russian formalists sought early on to elaborate an original conceptual body to understand the literary phenomena as emancipated from categories borrowed from sociology, philosophy or psychology. Such effort produced ground-breaking results, but also gave rise to deadlocks that are on the base of the crisis in literary theory in the 1970s and 1980s, when post-theories emerged bringing extra-literary elements (such as gender, politics, decolonial perspective) back to the spotlight. This paper argues these deadlocks have become evident in the early stages of the Formal School, when its theoretical construction was confronted with the practice of literary criticism. While theory and criticism fed each other back, the interrelations between them made their own shortcomings and limits explicit.

Abstract This work aimed to evaluate the monthly growth rate of 100 trees spread in different diametric classes and ecological groups of a secondary forest in the municipality of Igarapé-Açu, Pará, Brazil. These were selected randomly from 30 permanent plots and classified into 5 diametrical classes and separated into two ecological groups: Pioneers and Non-Pioneers. The monthly periodic increment (MPI) in diameter was measured for 11 months by means of diametric bands using digital calipers. The MPI means were evaluated by an analysis of variance (ANOVA) and Tukey’s mean comparison test. Individuals from both ecological groups had similar increments in the DBH IV diameter class and different in the others. There were mean increments in the diametric classes that did not differ within the ecological groups. The trees analyzed differed in the diametric growth rate according to the diametric classes, ecological groups and the month of analysis.

ABSTRACT Introduction Vesicoureteral Reflux (VUR) is characterized by a retrograde flow of urine from the bladder into the ureters and kidneys. It is one of the most common urinary tract anomalies and the major cause of urinary tract infection (UTI) in the first years of life. If not properly diagnosed and treated can lead to recurrent UTI, renal scar and, in severe cases, to end stage renal disease. Despite recent advances in scientific and technological knowledge, evaluation and treatment of VUR is still controversial and there is still considerable heterogeneity in evaluation methods and therapeutic approaches. The aim of the present consensus is to give a practical orientation on how to evaluate and treat VUR. Methods The board of Pediatric Urology of the Brazilian Society of Urology joined a group of experts and reviewed all important issues on Vesicoureteral Reflux evaluation and treatment and elaborated a draft of the document. On November 2017 the panel met to review, discuss and write a consensus document. Results and Discussion Vesicoureteral Reflux is a common and challenging problem in children. Children presenting with Vesicoureteral Reflux require careful evaluation and treatment to avoid future urinary tract infections and kidney scars. The panel addressed recommendations on up to date choice of diagnosis evaluation and therapies.

Resumo Fundamento: A segurança e a eficácia da varfarina dependem da qualidade do controle da anticoagulação. Estudos observacionais associam controle deficiente com aumento de morbidade, mortalidade e custos com saúde. Objetivos: Desenvolver um perfil de pacientes com fibrilação atrial não valvar (FANV) tratados com varfarina em ambiente ambulatorial e hospitalar privado brasileiro, avaliar a qualidade do controle da anticoagulação e sua associação com resultados clínicos e econômicos. Métodos: Este estudo retrospectivo, por meio de um conjunto de dados de seguros privados de saúde no Brasil, identificou pacientes com FANV tratados com varfarina entre 01 de maio de 2014 a 30 de abril de 2016, descreveu seu manejo da anticoagulação e quantificou os custos relacionados à doença. Foram recuperados dados demográficos, histórico clínico, medicação concomitante e tempo na faixa terapêutica (TTR) dos valores da razão normalizada internacional (RNI). Os pacientes foram agrupados em quartis de TTR, com um bom controle sendo definido como TTR ≥65% (método de Rosendaal). Sangramentos maiores e custos médicos diretos por todas as causas foram calculados e comparados entre subgrupos de controle bons e ruins. Valores de p < 0,05 foram considerados estatisticamente significantes. Resultados: A análise incluiu 1220 pacientes (mediana de seguimento: 1,5 anos; IIQ: 0,5-2,0). Em média, cada paciente recebeu 0,95 medidas mensais de RNI (RNI média: 2,60 ± 0,88, com 26,1% dos valores < 2 e 24,8% > 3), (mediana de TTR: 58%; IIQ: 47-68%), (TTR médio: 56,6% ± 18,9%). Apenas 31% dos pacientes estavam bem controlados (TTR médio: 78% ± 10%), com 1,6% apresentando grandes sangramentos na mediana do seguimento e custos médicos diretos por membro por ano (PMPY) de R$25.352 (± R$37.762). Pacientes com controle abaixo do ideal (69%) foram associados a 3,3 vezes mais sangramentos graves (5,3% vs. 1,6%; p <0,01) e custos 40% maiores (R$35.384 vs. R$25.352; p < 0,01). Conclusões: Mais de 60% dos pacientes estavam abaixo da meta desejada e os custos associados foram significativamente maiores nesta população.

Abstract Background: The safety and effectiveness of warfarin depend on anticoagulation control quality. Observational studies associate poor control with increased morbidity, mortality and healthcare costs. Objectives: To develop a profile of non-valvular atrial fibrillation (NVAF) patients treated with warfarin in a Brazilian private ambulatory and hospital setting, evaluate the quality of anticoagulation control, and its association with clinical and economic outcomes. Methods: This retrospective study, through a private health insurance dataset in Brazil, identified NVAF patients treated with warfarin between 01 MAY 2014 to 30 APRIL 2016, described their anticoagulation management, and quantified disease-related costs. Data on demographics, clinical history, concomitant medication and time in therapeutic range (TTR) of international normalized ratio (INR) values were retrieved. Patients were grouped into TTR quartiles, with good control defined as TTR ≥ 65% (Rosendaal method). Major bleeds and all-cause direct medical costs were calculated and compared between good and poor control subgroups. P-values < 0.05 were considered statistically significant. Results: The analysis included 1220 patients (median follow-up: 1.5 years; IQR: 0.5-2.0). On average, each patient received 0.95 monthly INR measurements (mean INR: 2.60 ± 0.88, with 26.1% of values < 2 and 24.8% > 3), (median TTR: 58%; IQR: 47-68%), (mean TTR: 56.6% ± 18.9%). Only 31% of patients were well-controlled (mean TTR: 78% ± 10%), with 1.6% having major bleeds within median follow-up, and direct medical costs per member per year (PMPY) of R$25,352(± R$ 37,762). Poorly controlled patients (69%) were associated with 3.3 times more major bleeds (5.3% vs. 1.6%; p < 0.01) and 40% higher costs (R$35,384 vs. R$25,352; p < 0.01). Conclusions: More than 60% of the patients were below the desired target and the associated costs were higher.

Abstract This study evaluated the production of endoxylanases by Streptomyces malaysiensis AMT-3 in submerged fermentation using by-products of the food industry at 28ºC. In shake-flasks experiments, the highest endoxylanase activity of 45.8 U.mL-1 was observed within 6 days in a medium containing (w/v) 2.5% wheat bran and 1.2% corn steep liquor. The same culture conditions were used to evaluate the enzyme production in a 2 L stirred tank reactor under different agitation (300, 450 and 600 rev.min-1) and aeration (30 and 60 L.h-1) conditions. The use of 450 rev.min-1 coupled to an aeration of 90 L.h-1 resulted on 81.3 U.mL-1 endoxylanase activity within 5 days. The effect of temperature and pH on endoxylanase activity and stability showed the highest activity at 60 ºC and pH 6.0. Zymography showed the presence of three xylanolytic bands with molecular masses of 690, 180 and 142 kDa. The results showed that the thermotolerant actinobacterial endoxylanase can be produced in high titers using by-product of the food industry.

RESUMO O semioticista Iuri Lótman escreveu contribuições decisivas no campo da semiótica da literatura. No entanto, ao longo dos anos 70 passa a ampliar seu universo de interesses para além do texto literário, trazendo contribuições para os estudos do cinema, das artes plásticas e mesmo das normas de etiqueta da nobreza russa. Neste artigo pretendo introduzir as contribuições de Lótman no campo da semiótica da cena e demonstrar como o semioticista russo realiza reflexões importantes em um campo até então pouco explorado dentro dos estudos semióticos. Ao analisar o caráter do espaço teatral, as relações entre texto e código, o papel da semiótica teatral e do ensemble cênico, Lótman retoma o caminho aberto pelo Círculo Linguístico de Praga e antecipa flancos de interesse que só recentemente seriam explorados pela semiótica teatral.

ABSTRACT The semiotician Yuri Lotman wrote decisive contributions to the field of semiotics of literature. However, throughout the 1970s he expanded his universe of interests beyond the literary text contributing to the study of cinema, fine arts and even Russian nobility’s code of behavior. In this article, I introduce Lotman’s writings in the field of theatre semiotics to demonstrate how the Russian semiotician brings important considerations to a field until then underexplored within semiotic studies. His reflections on the nature of the theatrical space, on the relations between text and code, on the role of theatre semiotics, and on the theatrical ensemble enlarged the path opened by the Linguistic Circle of Prague and anticipate discussions that only recently started to be explored by the semiotics of theatre.

Abstract Woody debris, defined as standing and downed deadwood, consists in an essential component of the forest carbon stock. However, few studies have been carried out to get an efficient and accurate sampling procedure for estimating it. This work proposes two methodologies to estimate the woody debris volume in a Brazilian mixed tropical forest: 1) two-stage systematic sampling, using a mixed methodology, in which the Strand’s method is applied to standing dead trees and stumps, and line intercept sampling is used to fallen trees and branches; and 2) ratio estimate of the sum of cross-sectional areas of deadwood pieces and forest basal area, aiming to obtain the total woody debris volume indirectly in the natural forest. Conversions for biomass and carbon stocks were made applying the mean basic density on the estimates of deadwood volumes. Both methodologies are accurate for woody debris volume estimates, with a sampling error equal to 16.1% (methodology 1) and 5.7% (methodology 2), at a 95% probability level. Thus, the methodology 2 has potential to be used in strategic forest inventories of woody debris, such as in National Forest Inventories, due to increasing importance of its quantification in all forest ecosystems.

O melão pepino Cucumis melo var.Cantalupensis Naud é uma espécie crioula que apresenta alta adaptabilidade às condições edafoclimáticas do semiárido nordestino, servindo como fonte de renda e alimentar. Nesse contexto, o objetivo do trabalho foi avaliar a qualidade fisiológica de sementes de melão pepino submetidas à irrigação com águas salinas de 0,012, 2, 4, 6 e 8 dS m-1, na percentagem de germinação, primeira contagem de germinação, índice de velocidade de germinação, tempo médio para a germinação, percentagem de plântulas normais fortes, normais fracas e anormais, no comprimento da parte aérea, comprimento de raiz, comprimento de plântulas e massa da matéria seca das plântulas. A salinidade da água não interferiu no processo de germinação das sementes de melão pepino, inibiu o crescimento da raiz principal e o comprimento das plântulas irrigadas com águas de salinidade superior a 3,8 e 4,3 dS m-1, respectivamente, e, portanto, superiores ao máximo permitido de 3 dS m-1 na irrigação convencional à maioria das plantas cultivadas.

The Charentais cantaloupe melon Cucumis melo var.Cantalupensis Naud is a creole species that presents high adaptability to the edaphoclimatic conditions of the Northeastern semiarid, representing a food and income source. In this context, the purpose hereof was to evaluate the physiological quality of Charentais cantaloupe melon seeds subjected to irrigation with salt waters of 0.012, 2, 4, 6, and 8 dS m-1 in the germination percentage, first germination counting, germination speed rate, average time for germination, percentage of regular strong, regular weak, and abnormal seedlings, in the aerial part length, root length, length of seedlings and seedlings dry matter. The water’s salinity did not interfere in the Charentais cantaloupe melon seed germination process, but inhibited the main root’s and length of irrigated with water salinity over 3.8 and 4.3 dS m-1, respectively, and therefore superior to the maximum allowed of 3 dS m-1 in the conventional irrigation of most of the cultivated plants.
