ABSTRACT Chromium is present in the tannery sludges worldwide making it a problem for agriculture. This study aimed to evaluate whether humus functions as a chromium stabilizing agent when using tannery sludge in the substrate of conilon coffee seedlings (Coffea canephora) and to determine what effects there are on leaf development and anatomy. Treatments consisted of a fixed dose of tannery sludge (30% of volume) on substrates of conilon coffee seedlings with different proportions of humus and subsoil (T-10, T-20, T-30, T-40% of humus). Information for the evaluation of leaf anatomy and seedling development was collected at 180 days after the planting of cuttings. From the phenological point of view, the treatments that best promoted seedling quality were T-30 and T-40. However, the greater the amount of humus in the substrate the greater the absorption of chromium by plants, which directly affected the organization of epidermal cells and leaf mesophyll. In addition, intense cytoplasmic degradation, ultrastructural changes in chloroplasts and mitochondria, and an increase in autophagic vacuoles were observed. We conclude that increasing the amount of humus in substrate with tannery sludge provides higher quality coffee seedlings, despite promoting greater absorption of chromium by plants and the consequent major intracellular disturbances.

Abstract Introduction Few instruments are available in Brazil to evaluate psychomotor activity in psychiatric emergency, clinical, and research settings. This study aimed to perform a cross-cultural adaptation of the Behavioral Activity Rating Scale (BARS) into Brazilian Portuguese and assess the adapted scale’s psychometric properties. Method An expert consensus committee conducted a translation and back-translation of the original scale, resulting in the BARS-BR. Four pairs of physicians administered the BARS-BR and the Sedation-Agitation Scale (SAS) to patients in a hospital psychiatry emergency room and patients in the hospital’s psychiatric wards. The BARS-BR was compared to the SAS to assess concurrent validity and internal consistency was evaluated with the Bland-Altman technique. Results In the emergency room, the correlation coefficients between the first and second assessments were rho = 0.997 and rho = 1.0, respectively. In the hospital wards, the correlation coefficient between the pair of evaluators was rho = 0.951. There were strong correlations between the BARS-BR score of the first examiner and the SAS score of the second examiner (rho = 0.903) and between the SAS score of the first examiner and the BARS-BR score of the second examiner (rho = 0.893). Conclusion The BARS-BR showed good psychometric properties, and we recommend its use because it constitutes an easy method for assessment of changes in psychomotor activity. Further studies are suggested to evaluate adoption and comprehension of the BARS-BR scale by all classes of healthcare professionals.

Resumo Esse estudo tem como objetivo avaliar a acurácia da análise microtomográfica em mensurações lineares e volumétricas em osso nativo (ON) e enxertado (OE). Para isso, 111 biópsias removidas de seios maxilares de pacientes enxertados com osso bovino desproteinizado foram coletadas e avaliadas. As medidas lineares foram realizadas para medir o comprimento do ON e do OE. Além disso, foi realizada a mensuração da quantidade de tecidos mineralizados em ON e OE. Na análise histomorfométrica a porcentagem de tecidos mineralizados do ON e OE foi obtida em dois cortes histológicos enquanto os tecidos mineralizados foram medidos em microtomografias variando os thresholds da escala de cinza variando de 90-250 a 90-150 com 10 níveis de variação entre cada. Em seguida, esses dados foram correlacionados para verificar o maior nível de R entre os intervalos dos thresholds testados na análise microtomográfica em relação aos dados obtidos na histomorfometria. O comprimento linear do ON foi de 2,44±0,91mm e 2,48±1,50mm, respectivamente, para análises microtomográfica e histomorfométrica (r=0,57), enquanto o comprimento linear do OE foi de 3,63±1,66mm e 3,13±1,45mm, respectivamente, para para análises microtomográfica e histomorfométrica (r =0,74) A histomorfometria detectou 45,91±11,69% de osso na porção de ON e 49,57±5,59% de osso e biomaterial na porção de OE. O volume total de tecidos mineralizados detectados pela análise microtomográfica que apresentou valores mais próximos da análise histomorfométrica foi de 43,75±15,39% no ON (Thresholds:90-240; r = 0,50) e 51,68±8,42% no OE (Thresholds:90-180; r =- 0,028). A análise microtomográfica apresentou boa acurácia na análise linear em ambas as porções das biópsias, porém a mesma apresentou boa acurácia para análise volumétrica apenas em áreas de ON.

Abstract The study aimed to evaluate the accuracy of Micro-CT in linear and volumetric measurements in native (NB) and grafted bone (GB) areas. A total of 111 biopsies of maxillary sinuses grafted with deproteinized bovine bone (DBB) in humans were evaluated. The linear measurements were performed to measure the length of the NB and GB. Furthermore, the amount of mineralized tissues at the NB and GB was performed. In the histomorphometry analysis the percentage of mineralized tissues at the NB and GB was obtained in two histological sections while the mineralized tissues were measure in the micro-CT varying the thresholds of the grayscale varying from 90-250 to 90-150 with 10 levels of variation between each one was applied. Then these data were correlated in order to check the higher r level between the histomorphometry and micro-CT thresholds intervals. The linear length of the NB was 2.44±0.91mm and 2.48±1.50mm, respectively, for micro-CT and histomorphometry (r =0.57), while the linear length of the GB was 3.63±1.66mm and 3.13±1.45mm, respectively, for micro-CT and histomorphometry (r =0.74) Histomorphometry showed 45.91±11.69% of bone in NB, and 49.57±5.59% of bone and biomaterial in the GB. The total volume of mineralized tissues that were closest to the histometric analysis were 43.75±15.39% in the NB (Threshold:90-240; r = 0.50) and 51.68±8.42% in the GB (Threshold:90-180; r =-0.028). The micro-CT analysis showed good accuracy in the linear analysis in both portions of the biopsies but for volumetric analysis just in NB.

Abstract People’s fascination with the art of funambulism has traversed generations and acquired new meanings over time. In contemporary times, the use of nylon straps arranged at varied heights marked the emergence of slackline, a sport that has attracted a large number of followers in recent decades. Despite this great popularity, it should be noted that, when some of the main research databases (Scielo, Web of Science, Scopus, SPORTDiscus and Science Direct) were consulted, little academic research was seen to have been conducted on the field, which shows the need for studies that address the practitioners of the sport, as well as its characteristics as a competitive physical activity. Thus, the aim of this study was to present and discuss the motivations to persist in slackline practice, more specifically, in the discipline of trickline. To obtain data, 14 male athletes were surveyed through semi-structured interviews. The data were analyzed according to the prerogative of Bardin’s (2011) Content Analysis . The results showed the presence of intrinsic and extrinsic motivational factors to continue slackline practice. It is therefore essential to distinguish these factors in order to meet the needs and desires of athletes to promote permanence in the sport over time.

Resumo A fascinação das pessoas pela arte do funambulismo ultrapassou gerações e adquiriu novos significados ao longo dos tempos. Na contemporaneidade, fitas de nylon dispostas nas mais variadas alturas caracterizaram a emergência do slackline, um esporte que adquiriu nas últimas décadas um número pronunciado de adeptos. Apesar dessa maior popularidade, compete ressaltar que ao consultarmos algumas das principais bases de dados (Scielo, Web of Science, Scopus, SPORTDiscus e Science Direct), observamos escassa produção acadêmica no que concerne à esse esporte, o que corrobora a necessidade de estudos que contemplem os protagonistas dessa prática, bem como suas características enquanto atividade física orientada para a competição. Assim, o objetivo desse estudo foi apresentar e discutir a motivação para a permanência na prática de slackline em sua vertente esportiva, mais especificamente, na categoria trickline. Para a obtenção dos dados, entrevistamos 14 atletas do sexo masculino por meio de entrevistas semiestruturadas. Os dados foram analisados segundo a prerrogativa da Análise de Conteúdo de Bardin (2011). Os resultados do estudo apontaram a presença de fatores intrínsecos e extrínsecos de motivação para a permanência na prática do slackline. Torna-se essencial distinguir esses fatores com o intuito de atender as necessidades e anseios dos esportistas com o fim de favorecer a permanência duradoura na prática esportiva.

Abstract BACKGROUND: Gastrointestinal (GI) symptoms are frequent complaints from individuals with nonalcoholic fatty liver disease (NAFLD). Dyspepsia is a universal clinical symptom and is among the most common GI complaints observed in the general population, but its prevalence in the population with NAFLD has not been previously investigated. OBJECTIVE: To compare the prevalence of functional dyspepsia (FD) between patients with NAFLD and controls without liver disease. DESIGN AND SETTING: Cross-sectional study at the Outpatient Liver Clinic, University Hospital, Belo Horizonte, Brazil. METHODS: We included 96 NAFLD patients and 105 controls without liver disease. All participants were assessed for GI symptoms in accordance with the Rome III criteria. Evaluation methods included a questionnaire for FD (validated in Brazil), laboratory tests and upper GI endoscopy. RESULTS: Mean age and sex were similar between the groups. The NAFLD group presented higher frequency of proton-pump inhibitor usage (31.3% vs 4.8%; P < 0.001) and prevalence of FD (25.0% versus 12.4%; P = 0.021). The symptom frequencies were as follows: postprandial distress, 22.9% versus 11.4% (P = 0.030); postprandial fullness, 18.8% versus 10.5% (P = 0.095); early satiation, 8.3% versus 5.7% (P = 0.466); and epigastric pain or burning, 18.8% versus 5.7% (P = 0.004), in NAFLD patients and controls, respectively. Multivariate analysis demonstrated that female sex (odds ratio, OR 6.97; 95% confidence interval, CI: 1.51-32.12; P = 0.013) and NAFLD diagnosis (OR 2.45; 95% CI: 1.14-5.27; P = 0.021) were independently associated with FD occurrence. CONCLUSION: FD occurs more frequently in individuals with NAFLD than in controls without hepatic disease.

Resumo Os avanços nos sistemas de produção buscam sempre alternativas para a melhoraria da produtividade. Uma das práticas recentes adotadas em plantios comerciais de bananas e plátanos referem-se à aplicação de fertilizantes líquidos em cachos, visando ao aumento da produtividade. O objetivo deste trabalho foi verificar se o uso de biofertilizantes à base de vinhaça pura ou associada a outros adubos químicos poderia proporcionar alterações morfofisiológicas nos frutos ou aumento de produtividade no plátano cv Terra Maranhão. Para a execução deste projeto, foi montado, em uma lavoura comercial, um delineamento em blocos casualizados, com 6 tratamentos e 3 repetições, tendo sido avaliadas características de produção e qualidade dos frutos na pós-colheita do plátano cultivar (cv) Terra Maranhão. Como resultado, pôde-se observar que as características morfofisiológicas de frutos recém-colhidos, que impactam a produtividade, como peso dos frutos e dos cachos, foram afetados pelos tratamentos, enquanto características da pós-colheita dos frutos maduros foram pouco afetadas pela aplicação de fertilizantes nos cachos, com exceção do conteúdo de SST. Conclui-se, portanto, com este experimento, que a produtividade da cultura aumentou significativamente em 17%, quando utilizada uma mistura de vinhaça, cloreto de potássio e ureia; entretanto, este mesmo tratamento provocou a redução significativa de 1,3 ºBrix em relação a testemunha.

Abstract Advances in production systems always aim at finding alternatives to improve crop productivity. One of the recent practices adopted in commercial banana and plantain plantations refers to the application of liquid fertilizers in bunches in order to increase productivity. This research aimed at verifying whether the use of biofertilizers based on pure vinasse or associated with other chemical fertilizers would provide morphophysiological changes in fruits or increase the productivity of ‘Terra Maranhão’ plantain cultivars. In order to carry out this project, a randomized block design with 6 treatments and 3 replicates was set up in a commercial crop and the postharvest production and quality characteristics of ‘Terra Maranhão’ plantain fruits were evaluated. The results showed that the morphophysiological characteristics of freshly harvested fruits that impact productivity such as the fruit weight and bunch weight were affected by treatments, as the postharvest characteristics of ripe fruits were little affected by the application of fertilizers in bunches, except for the SST content. It could be concluded that the crop yield increased significantly by 17% when using mixture of vinasse, potassium chloride and urea; however, this treatment caused significant reduction of 1.3 ºBrix compared to control.

Abstract The aim was to identify the predominant variables in the differentiation of meat quality of cattle submitted to surgical castration, immunocastration, or non-castration and finished in a tropical pasture. Thirty-nine crossbred cattle were used and distributed in three treatments: i) surgical castration; ii) immunocastration; and iii) non-castration, with an initial mean age of 14.06±0.72 months and a mean weight of 284.10±31.40 kg. We used the principal component analysis to differentiate the qualitative meat characteristics between the treatments. Based on that analysis, we found that the first three principal components explained 71.44% of the total variation in the meat quality data, which ensures that the variation found is associated with the effect of the treatments. The characteristics correlated with the first three principal components and responsible for the discrimination between sexual conditions were subcutaneous fat thickness, instrumental meat color, cooking loss and shear force. These characteristics were similar among castrated animals, regardless of the methods. Therefore, immunological castration preserves the attributes of the meat and prevents possible damage to the physical and mental integrity of the animals. Finally, principal component analysis is an important methodology in the objective investigation of beef meat attributes.

Abstract The purpose of this study is to estimate the prevalence of and characterize the use of psychoactive drugs among drug users in a Brazilian municipality, relating the findings to factors associated with the consumption of these substances. Through a cross-sectional design, 1,355 drug users from the public health systems community pharmacies were interviewed. Sociodemographic and health-related data were collected, as well as any other prescribed drugs. The prevalence of psychoactive drug use within the last month was 31.0%, with antidepressants and benzodiazepines being the most prescribed (53.5% and 24.6% respectively). Most psychoactive drug users were female (81.9%), lived with a partner (52.6%), had private health insurance (69.2%) and a monthly per-capita income up to one minimum wage (54.0%). The adjusted Odds Ratio (OR) confirmed the following factors to be positively associated with the use of psychoactive drugs: female gender (OR=2.06; 95% CI 1.44; 2.95), age ≥60 years old (OR=1.77; 95% CI 1.26; 2.48), follow-up with a psychologist (OR=4.12; 95% CI 1.84; 5.25), absence of regular physical activity (OR=1.59; 95% CI 1.13; 2.23), and smokers (OR=1.94; 95% CI 1.26; 2.97). Approximately one out of three individuals used at least one psychoactive drug. Health managers should focus the planning and actions aimed at their rational use for these groups, leading to increased overall treatment success.

The objective of this work was to control the purity level of canephora coffees (Conilon coffee) from the state of Espírito Santo (Brazil), as a function of the addition of grounds produced by the coffees themselves using a portable microspectrometer in the infrared region. (microNIR), associated with chemometric tools. The PCA model grouped the coffees according to the level of adulterant in the samples and showed that the presence of moisture and polysaccharides is important for the discrimination between pure and adulterated samples. PLS-DA and SIMCA classification models were built with commercial samples and resulted in the discrimination of authentic and non-authentic samples with accuracy values above 90% and 82% for PLS-DA and SIMCA, respectively. The quantification results presented by the PLS model were satisfactory for all models, reaching the best results at 75 °C with RMSEP values of 6.13 wt%, R2p = 0.9917; and LOD in the range of 5.6-8.9 wt%; LOQ = 17-26.8 wt%, according to IUPAC; relative standard deviation for repeatability of 1.0 and 1.7 wt%; and intermediate precision of 3.4 and 1.1 wt% for low (<10 wt%) and high (≈ 90 wt%) levels of adulterants, respectively. Therefore, this work represents the first exploratory study to analyze adulterations with coffee grounds by portable NIR, demonstrating the potential of the equipment against this type of adulteration.

RESUMO Objetivo. Avaliar, por meio de métodos semiparamétricos de análise de sobrevida, a relação entre covariáveis e tempo até a morte em pacientes com câncer de mama e determinar o poder discriminatório na árvore de inferência condicional em pacientes que tiveram câncer. Métodos. Estudo de coorte retrospectivo realizado a partir de dados coletados de prontuários médicos de mulheres com câncer de mama, tratadas entre 2005 e 2015 no Hospital da Fundação Assistencial da Paraíba em Campina Grande, no estado da Paraíba, Brasil. As curvas de sobrevida foram estimadas pelo método de Kaplan-Meier, regressão de Cox e árvore de decisão condicional. Resultados. As pacientes com subtipos moleculares de tumor triplo-negativo tiveram uma sobrevida menor em comparação com as que apresentavam tumor com receptores hormonais. O acréscimo de hormonioterapia reduziu o risco de morte em 5,5%. O risco de morte foi 34,5% menor em pacientes com HER2+ quando comparadas às que tinham tumores sem a expressão desse gene. A mediana de sobrevida das pacientes tratadas com hormonioterapia foi de 4 753 dias. Conclusões. A presente análise revela um cenário favorável para o uso de imunoterapia em pacientes com superexpressão de HER2. Outros estudos devem ser realizados para avaliar a eficácia da imunoterapia em outras doenças e os fatores que favorecem o prognóstico e melhoram a qualidade de vida dessas pessoas.

ABSTRACT Objective. To evaluate, using semiparametric methodologies of survival analysis, the relationship between covariates and time to death of patients with breast cancer, as well as the determination discriminatory power in the conditional inference tree of patients who had cancer. Methods. A retrospective cohort study was conducted using data collected from medical records of women who had breast cancer and underwent treatment between 2005 and 2015 at the Hospital da Fundação de Assistencial da Paraíba in Campina Grande, State of Paraiba, Brazil. Survival curves were estimated using the Kaplan–Meier method, Cox regression, and conditional decision tree. Results. Women with triple-negative molecular subtypes had a shorter survival time compared to women with positive hormone receptors. The addition of hormone therapy reduced the risk of a patient dying by 5.5%, and the risk of a HER2-positive patient dying was 34.5% lower compared to those who were negative for this gene. Patients undergoing hormone therapy had a median survival time of 4 753 days. Conclusions. This paper shows a favorable scenario for the use of immunotherapy for patients with HER2 overexpression. Further studies could assess the effectiveness of immunotherapy in patients with other conditions, to favor the prognosis and better quality of life for the patient.

ABSTRACT Zucchini (Cucurbita pepo L.) is a horticultural plant species of great socioeconomic value in tropical countries such as Colombia and Brazil. The production of zucchini is qualitatively and quantitatively affected by many diseases, especially viruses belonging to the Potyvirus (Zucchini yellow mosaic virus - ZYMV) and Comovirus (Squash mosaic virus - SqMV) groups. The primary strategy to reduce the spread of potentially damaging plant viruses is the development of genotypes with genetic tolerance; however, there are not many zucchini genotypes with multiple tolerance. Therefore, this study evaluated 66 zucchini genotypes to find sources of tolerance to the ZYMV and SqMV viruses. This experiment was conducted in a completely randomized design using genotypes from the germplasm bank of the Federal University of Uberlândia, including the genotypes: Emanuela (common commercial genotype) ‘Tronco Caserta’ (susceptible genotype) and PX 13067051 (resistant genotype). Leaf extracts containing viral particles were used as inoculant, and the distribution of grades of tolerance was recorded at the seedling stage. The lineages UFU-C×UFU-A#18#3;1, UFU-C×UFU-F#19#11;3, UFU-F#4#9;1, and UFU-D×UFU-F#7#21;1 and the Emanuela cultivar are alternatives for the production of new zucchini genotypes or hybrids with tolerance to the viruses ZYMV and SqMV. More severe symptoms were observed, as well as a larger number of susceptible genotypes for the ZYMV virus, indicating that this virus has great potential for causing damage and losses to zucchini crops.

RESUMEN El calabacín (Cucurbita pepo L.) es una especie de planta hortícola de gran valor socioeconómico en países tropicales como Colombia y Brasil. Su producción se ve afectada tanto cualitativa como cuantitativamente por muchas enfermedades en especial por los virus pertenecientes a los grupos Potyvirus (Virus de mosaico amarillo de Zucchini - ZYMV) y Comovirus (Virus de mosaico de calabaza - SqMV). La estrategia principal para reducir la propagación de virus vegetales potencialmente dañinos es el desarrollo de genotipos con tolerancia genética; sin embargo, no hay muchos genotipos de calabacín con tolerancia múltiple. Por lo tanto, este estudio evaluó 66 genotipos de calabacín para encontrar fuentes de tolerancia a los virus ZYMV y SqMV. El experimento se llevó a cabo en un diseño completamente aleatorio utilizando genotipos del banco de germoplasma de la Universidad Federal de Uberlândia, incluyendo los genotipos: 'Emanuela' (genotipo comercial común), 'Caserta' (genotipo susceptible) y 'PX 13067051' (genotipo resistente). Los extractos de hojas que contienen partículas virales se utilizaron como inoculantes y la distribución de los grados de tolerancia se registró en la etapa de plántula. Los linajes UFU-C×UFU-A#18#3;1, UFU-C×UFU-F#19#11;3, UFU-F#4#9;1, UFU-D×UFU-F#7#21;1, y el cultivar Emanuela son alternativas para la producción de nuevos genotipos de calabacín o híbridos tolerancia a los virus ZYMV y SqMV. Se observaron síntomas más graves, así como un mayor número de genotipos susceptibles para el virus ZYMV, lo que indica que este virus tiene un gran potencial para causar daños y pérdidas al cultivo de calabacín.

Abstract INTRODUCTION This systematic review aimed to assess antibiotic use in Brazilian hospitals in the 21st century, as well as to understand the different drug utilization metrics adopted to assess the consumption of these drugs. METHODS We systematically reviewed five databases (MEDLINE [Medical Literature Analysis and Retrieval System Online], CENTRAL [The Cochrane Central Register of Controlled Trials], EMBASE® [Excerpta Medica Database], Scopus [Elsevier’s abstract and citation database], and LILACS [Literatura Latino-Americana e do Caribe em Ciências da Saúde]) for observational or experimental studies that assessed antibiotic utilization in Brazilian hospitals. The main outcomes were the drug utilization metrics and the consumption of antibiotics. RESULTS We included 23 studies, of which 43.5% were carried out in adult and pediatric care units, 39.1% in adult units, and 17.4% in pediatric units. Regarding the complexity of healthcare, 26.1% of the studies were performed in intensive care units. Two drug utilization metrics were used in these studies: the defined daily dose (DDD) and the percentage of antibiotic prescriptions. The most commonly used antibiotic classes were third-generation cephalosporins, carbapenems, fluoroquinolones, and combinations of penicillins when the DDD was the adopted drug utilization metric. CONCLUSIONS Although few studies have been conducted, existing data indicate a high use of broad-spectrum antibiotics. We found that the lack of standardized antibiotic utilization metrics impaired the mapping of drug consumption at the national level.

ABSTRACT: Coffee is a crop of great economic importance in Brazil. To ensure high productivity, and profitability irrigation management becomes important. The knowledge of the crop's root system is of utmost importance for the development of the crop as for the correct management of irrigation. The objective of this study was to characterize the root system of the Conilon coffee plant under localized irrigation. The experiment was carried out in two cultivated areas in Sao Mateus-ES, in a completely randomized design in a plot subdivided 4 x 6, four points concerning the plant and six depths, with five replications. There were two in the line and six in line with a distance between them 0.20 m. The line between the coffee portion is divided into 6 x 5, five points concerning the plantation, and the depth of six tracks, with five repetitions. Volume, surface area, length, and root diameter were evaluated. The coffee Conilon under drip under (area 01) showed 74.5% and 64.5% (sandy to medium texture), and 75.4% and 70.2% (sandy to clay texture) of the volume and root surface area, concentrated up to the depth of 0.30 m. The root system of the Conilon genotype 02 presented 70.5% of the root volume for both textures studied, up to 0,60 m of the plant's trunk. The root surface area was 69% and 66.4% up to 0.60 m of the plant's trunk for areas 01 and 02, respectively.

RESUMEN: El café es un cultivo de gran importancia económica en Brasil. Para asegurar una alta productividad y rentabilidad se vuelve importante el manejo del riego. El conocimiento del sistema radicular del cultivo es de suma importancia para el desarrollo del cultivo como para el correcto manejo del riego. El objetivo de este estudio fue caracterizar el sistema radicular de la planta de café Conilon bajo riego localizado. El experimento se llevó a cabo en dos áreas cultivadas en Sao Mateus-ES, en un diseño completamente al azar en una parcela subdividida: 4 x 6, cuatro puntos con respecto a la planta y seis profundidades, con cinco repeticiones. Siendo dos en línea y seis entre línea con una distancia entre ellas de 0,20 m; 6 x 5, cinco puntos en referencia a la plantación y seis bandas de profundidad, con cinco repeticiones. Se evaluó el volumen, área superficial, longitud y diámetro de raíz. El café Conilon bajo goteo (área 01) mostró 74,5% y 64,5% (en textura arenosa a media), y 75,4% y 70,2% (en textura arenosa a arcillosa) del volumen y área de la superficie radicular, concentrada hasta la profundidad de 0,30 m. Em el sistema de raíces del genotipo Conilon 2, el 70,5% presento un volumen de raíz para ambas texturas estudiadas a 0,60 m del tallo de la planta. El área superficial de raíz fue de 69% y 66,4% hasta 0,60 m del tronco del árbol para las áreas 01 y 02, respectivamente.
