SUMMARY: This study focuses on the review and proposal for anatomical terminology associated with the anatomical concept of Hyrtl´s porus crotaphitico-buccinatorius (PCBH), which is a passage area for the lateral divisions of the mandibular nerve in the infratemporal fossa. The objective of this research is to determine the most appropriate anatomical term from the perspective of international anatomical terminology to describe the structure known as PCBH. Furthermore, it seeks to provide solid proof, based on scientific and historical evidence that supports the correct choice of the term for international anatomical terminology in order to further precise and uniform communication in anatomy and medical science. The detailed analysis of the existing structure highlights the lack of descriptive information and the presence of eponyms. The proposed "Infratemporal Pterygoalar Foramen" is presented as a more precise alternative, supported by historical and etymological definitions. Each component of this new term is carefully selected, more accurately reflecting the location, components, shape and anatomical characteristics of the structure. This research contributes to the standardization and continuous improvement of international anatomical terminology, facilitating more effective communication in the scientific and medical field.

Abstract Distichlis spicata is a gramineous halophyte species that grow around the coastal areas. The objective of the study was to identify the modifications in the anatomical structure of stomates of the D. spicata leaf epidermis, cultivated with irrigation and without irrigation conditions. Two populations were selected, 1) plants of D. spicata with irrigation and 2) plants of D. spicata without irrigation. Ten plants per replication were selected from each population, and from each selected plant, the fourth leaf was taken. Each leaf was cut longitudinally into four segments which were dried and analyzed using an Electronic Scanning Microscope. The variables measured were the stomatal density, length, and width of stomates and pores, the stomatal area, the proportion of the pore area concerning the size of the stomata, and the stomata proportion per surface. The results showed that D. spicata populations with irrigation and without irrigation showed anatomical modifications in the structure of stomates in the adaxial epidermis but not in the abaxial epidermis. In the adaxial epidermis, the plants with irrigation showed higher values of stoma length, stoma width, stoma area and pore length, while plants without irrigation showed higher values of proportion pore/stoma and stomatal density. The D. spicata plants without irrigation showed small stomates than plants with irrigation, also, the plants without irrigation, increased the accumulation of salt crystals in the abaxial epidermis.

Resumen Distichlis spicata es una especie de gramínea halófita que crece en las zonas costeras. El objetivo del estudio fue identificar las modificaciones en la estructura anatómica de estomas de la epidermis foliar de D. spicata, cultivadas con riego y sin riego. Se seleccionaron dos poblaciones, 1) plantas de D. spicata con riego y 2) plantas de D. spicata sin riego. De cada población se seleccionaron 10 plantas por repetición y de cada planta seleccionada se tomó la cuarta hoja. Cada hoja se cortó longitudinalmente en cuatro segmentos que se secaron y analizaron utilizando un microscopio electrónico de barrido. Las variables medidas fueron la densidad estomática, largo y ancho de estomas y poros, el área estomática, la proporción del área de poros con respecto al tamaño de los estomas y la proporción de estomas por superficie. Los resultados mostraron que la población de D. spicata con riego y sin riego mostraron modificaciones anatómicas en la estructura de los estomas en la epidermis adaxial pero no en la epidermis abaxial. En la epidermis adaxial, las plantas con riego presentaron valores más altos de longitud de estoma, ancho de estoma, área de estoma y longitud de poro, mientras que las plantas sin riego mostraron valores más altos de proporción poro/estoma y densidad estomática. Las plantas de D. spicata sin riego presentaron estomas más pequeños respecto a las plantas con riego; además, las plantas sin riego incrementaron la acumulación de cristales de sal en la epidermis abaxial.

Abstract Three magnetotelluric stations located on the Eastern Cordillera of Colombia and belonging to the Geophysical Network of the National University of Colombia (TUNJ, USME, and VCIO) have been used to detect spatial and temporal anomalies in apparent resistivity to depths exceeding 200 km, in the period from April 2018 to June 2021. From this monitoring, it was observed that transient anomalies took place hours before the seismic crisis of April 23, 2018, in the Bucaramanga Seismic Nest (BSN). Among the main findings of this work, it was possible to identify a potential association between apparent resistivity anomalies prior to or during four seismic events with 3,3 ≤ Mw < 4,3 at a depth of 115 ≤ H < 154 km on April 23, 2018. The association between resistivity anomalies and seismic events is explained by other authors as a fluid migration process, which generates pore pressure that exceeds effective stress and causes fracturing within the BSN.

Resumen Tres estaciones magnetotelúricas, ubicadas sobre la Cordillera Oriental de Colombia y pertenecientes a la Red Geofísica de la Universidad Nacional de Colombia (TUNJ, USME y VCIO), han sido utilizadas para detectar anomalías espaciales y temporales de la resistividad aparente a una profundidad superior a 200 km, en el período abril de 2018 hasta junio de 2021. A partir de este monitoreo se observó que existen anomalías transitorias horas antes de la crisis sísmica del 23 de abril de 2018 en el Nido Sísmico de Bucaramanga (NSB). Dentro de los principales hallazgos de este trabajo, se pudo identificar una posible asociación entre anomalías de resistividad aparente previas o durante cuatro eventos sísmicos con 3,3 ≤ Mw < 4,3 a una profundidad de 115 ≤ H < 154 km el 23 de abril de 2018. La asociación entre anomalías de resistividad y eventos sísmicos se explica por otros autores como un proceso de migración de fluidos, el cual genera presión de poro que supera el esfuerzo efectivo y provoca el fracturamiento dentro del NSB.

ABSTRACT: The effect of different feed substrates incubated in filter bags [no bag (NB); Ankom® F57, 25 μm pore size (25AN); polyester, 45 μm pore size (45PB); polyester, 67 μm pore size (67PB) ] or dispersed in the medium on gas production, digestion and rumen fermentation was evaluated using an in vitro gas production system. Filter bags reduced (P < 0.01) gas production but increased (P < 0.01) the in vitro dry matter digestibility (45PB and 67PB). Additionally, the use of filter bags with smaller pore size, reduced total volatile fatty acid (P < 0.01), but had minimal effects on acetate, propionate, and butyrate concentration. Our research suggested that using filter bags with a pore size of 67 µ would reduce some negative effects of incubating feed substrate dispersed in the medium or in filter bags with smaller pore size. However, the use of bags with a larger pore size might allow the wash out of small feed particles with consequent overestimation of digestibility.

As bolsas de filtro reduziram (P < 0,01) a produção de gases, mas aumentaram (P < 0,01) a digestibilidade da matéria seca in vitro (45PB e 67PB). Adicionalmente, o uso de bolsas de filtro com tamanho de poro menor reduziu o ácido graxo volátil total (P < 0,01), mas teve efeitos mínimos na concentração de acetato, propionato e butirato. Nosso trabalho sugere que usar sacos de filtro com tamanho de poro de 67 µ reduziria alguns efeitos negativos da incubação de substrato de alimentação disperso no meio ou em sacos de filtro com tamanho de poro menor.

RESUMO A realcalinização química (RAQ) e a realcalinização eletroquímica (RAE) são procedimentos utilizados como reparo de estruturas em concretos sujeitos à corrosão nas armaduras por ação da carbonatação. A premissa é elevar o pH da solução do poro do concreto, com o intuito de reestruturar o filme passivo das armaduras. A RAE é aplicada em estruturas a 40 anos e apresenta eficácia na reestruturação desta película. Já a RAQ é um método pouco abordado no meio cientifico. Este trabalho sintetiza informações, através de uma Revisão Sistemática da Literatura (RSL) com a técnica de snowballing, foram aderidos 24 trabalhos dos quais levantou-se os principais métodos de aplicação, soluções alcalinas e reações físico-químicas. Foi realizada uma análise comparativa entre a RAE e a RAQ, apesar de serem governados por mecanismos diferentes ambos foram eficazes em um período de tempo de 15 dias para reestabelecer o pH superior a 12, sendo também capazes de reestruturar o filme passivo das armaduras em sistemas com perda de massa decorrentes da corrosão abaixo de 0,25%.

ABSTRACT Chemical realkalization (CRA) and electrochemical realkalization (ERA) are procedures used to repair concrete structures subject to corrosion in reinforcement due to carbonation. The premise is to raise the pH of the concrete pore solution, with the aim of restructuring the passive film of the reinforcement. RAE has been applied to structures for 40 years and is effective in restructuring the passive film. The CRA is a little discussed method in scientific circles. This paper synthesizes information on these methods, through a Systematic Literature Review (SLR) and snowballing technique, with the adherence of 24 works where the main methods of applying treatments, alkaline solutions and physical-chemical reactions. A comparative analysis was carried out between ERA and CRA, although being governed by different mechanisms both raised the pH of the carbonation front to a value higher than 12, were effective in a period less than 15 days, and were also capable of restructuring the passive film of reinforcement in systems with mass loss due to corrosion below 0.25%. The main gaps are CRA reaction mechanisms, changes in concrete properties, duration of both treatments and greater predisposition to the alkali-aggregate reaction after treatment.

ABSTRACT The soot generated in foundry sands is an impediment to the reuse of the sands due to its contamination, therefore catalytic oxidation is necessary to increase the rate of soot oxidation at lower temperatures, improving the energy and environmental efficiency of the recovery process. NiO-CeO2 mixed oxides catalysts were prepared by solvent evaporation method with Ni:Ce molar ratios of 0.5:9.5, 1:9, 5:5, and 9:1, represented as Ni0.5Ce9.5, Ni1Ce9, Ni5Ce5 y Ni9Ce1, respectively and the precursors as CeO2 and NiO catalyst were also prepared through the same method. All the samples were characterized by different techniques based on their chemical, structural, morphological, textural composition, and redox properties. Characterization techniques were N2 sorption (BET method), X-ray diffraction (XRD), thermogravimetric analysis (TGA), H2 temperature programmed reduction (TPR-H2), Raman laser spectroscopy (LRS), and Fourier transform infrared spectroscopy (FTIR). The catalytic activity of the catalysts was evaluated by TGA under synthetic air as feed gas under tight contact for soot combustion. Calcinations at 800°C and 600°C of the mixed catalysts showed a low specific surface area (3-74 m2 g-1) with average crystallite sizes that varied with the different NiCe values (9-22 nm). However, an increase in the volume of the mesoporous pore was observed, an important parameter for the oxidation of soot with air. Likewise, the X-ray diffractograms of the NiCe catalysts showed a partial introduction of the Ni2+ ions to the CeO2 fluorite lattice through a displacement with respect to the initial position of the CeO2 diffractogram. The catalyst Ni0.5Ce9.5 (600), obtained the best catalytic activity (T50 =519.43 °C) compared to the catalysts Ni1Ce9, Ni5Ce5 y Ni9Ce1 and CeO2 calcined at 800°C and 600 °C. The soot oxidation kinetics were reported, where the activation energy (Ea) was determined, both for catalyzed and non-catalyzed soot under TGA with air flow. Therefore, it was concluded that the catalyst Ni0.5Ce9.5 (600) effectively improved the catalytic activity of the catalyst (Ea = 73 kJ mol-1) and reduced the combustion temperature, which generates the removal of soot at a lower temperature.

RESUMEN El hollín generado en las arenas de fundición es un impedimento para la reutilización de las arenas debido a su contaminación, por ello la oxidación catalítica es necesaria para incrementar la velocidad de oxidación del hollín a menores temperaturas, mejorando la eficiencia energética y ambiental del proceso de recuperación. Los catalizadores mixtos de NiCe fueron preparados mediante el método de evaporación de solvente en proporciones molares Ni:Ce de 0.5:9.5, 1:9, 5:5, y 9:1 representados como Ni0.5Ce9.5, Ni1Ce9, Ni5Ce5 y Ni9Ce1, respectivamente y los catalizadores másicos CeO2 y NiO también fueron preparados por el mismo método. Todas las muestras se caracterizaron mediante diferentes técnicas basadas en su composición química, estructural, morfológica, textural y propiedades redox. Las técnicas de caracterización fueron: sorción de N2 (método BET), difracción de rayos X (XRD), termogravimetría (TGA), reducción a temperatura programada con H2 (TPR-H2), espectroscopía láser Raman (LRS), y espectroscopía infrarroja por transformada de Fourier (FTIR). La actividad catalítica se evaluó por TGA bajo aire sintético en contacto directo para la combustión del hollín. La calcinación a 800 °C y 600 °C de los catalizadores mixtos mostraron una baja superficie específica (3-74 m2 g-1) con tamaño promedio de cristalita que variaron con los distintos valores NiCe (9-22 nm). Sin embargo, se observó un incremento en el volumen del poro mesoporoso, un importante parámetro para la oxidación del hollín con aire. Asimismo, los difractogramas de rayos X del catalizador NiCe mostraron una introducción parcial de los iones Ni2+ a la red de la fluorita del CeO2 mediante un desplazamiento con respecto a la posición inicial del difractograma del CeO2. El catalizador Ni0.5Ce9.5 calcinado a 600 °C obtuvo la mejor actividad catalítica (T50 = 519.43 °C) comparado con los catalizadores Ni1Ce9, Ni5Ce5 y Ni9Ce1 and CeO2 calcinados a 800 °C y 600 °C. Se evaluó la cinética de oxidación del hollín, donde se determinó la energía de activación (Ea) tanto para el hollín catalizado como para el no catalizado bajo TGA con flujo de aire y se concluyó que el catalizador Ni0.5Ce9.5 (600) mejoró efectivamente la actividad catalítica (Ea = 73 kJ mol- 1) generando la eliminación del hollín a una temperatura más baja.

Abstract Trichofolliculoma is an infrequent benign tumor of the hair follicle, with a higher prevalence between the second and sixth decade of life. It usually presents as a solitary lesion in the form of a nodule, papules or asymptomatic skin-colored plaques with a pore or central cavity obstructed with keratin from which a “tuft of hairs” emerges.The most frequent location is usually the face, followed by the scalp and neck.1 Histopathological characteristics are diagnostic. We report a case of a 44-year-old man with multiple trichofolliculomas on his face.

Abstract Paratanaisia bragai is a digenetic trematode that reaches sexual maturity in the kidney collecting ducts of domestic and wild birds, while the snails Subulina octona and Leptinaria unilamellata serve as its intermediate hosts in Brazil. The present study analyzed the morphology and morphometry of P. bragai. Adult specimens of the parasite were collected from naturally infected Columba livia kidneys, fixed and prepared for observation via bright field and differential interference contrast light microscopy and scanning electron microscopy. The parasite has an elongated and flattened body, with a subterminal oral sucker located at the anterior end of the body, as observed by all techniques used. Staining the parasite with hematoxylin-eosin enabled observation of the pharynx, located posteriorly to the oral sucker, the vitelline glands, which are extra-cecal and extend anteriorly to the pre-ovarian region and later to the median region of the body, and intestinal caeca parallel to the vitelline glands. The presence and functionality of the acetabulum are controversial points in the literature, but it was observed in all specimens analyzed by scanning electron microscopy, with a major diameter of 38.36 ± 6.96 (28.77 – 45.39) and minor diameter of 31.59 ± 7.04 (21.75 - 38.16). Close to the acetabulum, scales were observed in the integument of the parasite. Scales with (1 - 5) blade divisions were identified. In the genital pore, it was possible to see the everted cirrus with rosette shape. The excretory pore (first morphometric record) is dorsal and subterminal, with major diameter of 12.27 ± 9.16 (5.79 - 18.75) and minor diameter of 3.95 ± 1.49 (2.89 - 5.00). birds Brazil P kidneys body used hematoxylineosin hematoxylin eosin pharynx glands extracecal extra cecal preovarian pre ovarian literature 3836 38 36 38.3 696 6 96 6.9 28.77 2877 28 77 (28.7 45.39 4539 45 39 3159 31 59 31.5 704 7 04 7.0 21.75 2175 21 75 (21.7 38.16. 3816 38.16 . 16 38.16) 1 ( 5 identified shape first record 1227 12 27 12.2 916 9 9.1 5.79 579 79 (5.7 18.75 1875 18 395 3 95 3.9 149 49 1.4 2.89 289 2 89 (2.8 5.00. 500 5.00 00 5.00) 383 38. 69 6. 28.7 287 (28. 45.3 453 4 315 31. 70 0 7. 21.7 217 (21. 381 38.1 122 12. 91 9. 5.7 57 (5. 18.7 187 3. 14 1. 2.8 8 (2. 50 5.0 28.

Resumo Paratanaisia bragai é um trematódeo digenético que atinge a maturidade sexual nos ductos coletores de aves domésticas e silvestres, enquanto os moluscos Subulina octona e Leptinaria unilamellata atuam como seus hospedeiros intermediários no Brasil. O presente estudo analisou a morfologia e morfometria de P. bragai. Amostras adultas do parasito foram coletadas de rins de Columba livia naturalmente infectada, fixadas e preparadas para observação na microscopia de campo claro e microscopia de luz de contraste de interferência diferencial e microscopia eletrônica de varredura. O parasite possui corpo alongado e achatado, com uma ventosa oral subterminal localizada na extremidade anterior do corpo, conforme observado por todas as técnicas utilizadas. A coloração do parasito com hematoxilina-eosina permitiu observar a faringe, localizada posteriormente à ventosa oral, as glândulas vitelogênicas, que são extracecais e estendem-se anteriormente à região pré-ovariana e posteriormente à região mediana do corpo, e os cecos intestinais paralelos às glândulas vitelinas. A presença e funcionalidade do acetábulo são pontos controversos na literatura, mas foi observado em todos os espécimes analisados por microscopia eletrônica de varredura, com diâmetro maior de 38.36 ± 6.96 (28.77 – 45.39) e diâmetro menor de 31.59 ± 7,04 (21.75 – 38.16). Próximo ao acetábulo foram observadas escamas no tegumento do parasito. Escamas com (1 - 5) divisões de lâmina foram identificadas. No poro genital, foi possível visualizar o cirro evertido com formato de roseta.

ABSTRACT The proper handling of porous structures in biomedical applications has relevant importance to avoid bone resorption and to allow the correct bone ingrowth. This structure leads to the nucleation and growing of bone inside them, obtaining a correct bonding between implant and bone. Consequently, this work investigates a manufacturing process of porous titanium structures obtained by means of a powder metallurgy technique based on gel-casting and sintering. This technique allows us to control the size, shape and distribution of the pores aiming to obtain a metallic structure capable to be utilized for biomedical implants. Samples were prepared by mixing different weight fractions of titanium hydride powder and acrylic resin powder (analyzed mixes were composed of 3%, 6%, 9%, 12%, 15%, 18% and 21% weight fraction of acrylic resin). The results indicate that it is possible to get samples with adequate porous structure, and microstructures with different kind of porosities (11% to 91% pore fraction) and porous size (3 µm up to 195 µm) in a wide range of values. This process allows to choose the appropriate pore characteristics for a certain application. ingrowth them Consequently gelcasting gel casting sintering implants analyzed 3 3% 6 6% 9 9% 12 12% 15 15% 18 21 resin. . resin) 11% 11 (11 91 ( 19 values application 1 2 (1

RESUMEN El manejo adecuado de estructuras porosas, en aplicaciones biomédicas, tiene una relevante importancia en evitar la reabsorción y permitir el correcto crecimiento óseo. Estas estructuras conducen a la nucleación y crecimiento del hueso en su interior, consiguiendo una óptima unión entre el implante y este. En consecuencia, este trabajo investiga un proceso de fabricación de estructuras porosas de titanio obtenidas mediante una técnica pulvimetalúrgica basada tanto en el método de gel-casting como en la sinterización. Estas técnicas nos permiten controlar la cantidad, tamaño, forma y distribución de los poros, con el objetivo de obtener una estructura metálica apta para ser utilizada en implantes biomédicos. Las muestras, se preparan mezclando diferentes fracciones en peso de polvo de hidruro de titanio y polvo de resina acrílica. Se emplean mezclas compuestas por 3%, 6%, 9%, 12%, 15%, 18% y 21% de fracción en peso de resina acrílica. Los resultados indican que es posible obtener muestras con estructuras porosas adecuadas y microestructuras con valores de porosidad de 11% a 91% de fracción de poro, con tamaños de 3 µm a 195 µm.

Bovine trypanosomiasis is a parasitic disease caused by protozoans of the genus Trypanosoma. The disease cause economic losses in livestock production. In order to determine the status of research on this disease in Côte d'Ivoire, we used the systematic review method and meta-analysis. Three electronics databases, namely Google Scholar, PubMed and CrossRef were used to search for publications on trypanosomiasis prevalence that met our inclusion criteria. Twenty five articles were identified, 11 of which met the inclusion criteria. Bovine trypanosomiasis prevalence of 2.99% (95% confidence interval [CI]: 2.96% - 3.01%) to 25.28% (95% CI: 25.17% - 25.38%) were recorded between 1960 and 2021. The analyses showed that the most infected regions were the Bagoue 11.26% (95% CI: 11.25% - 11.27%), Bounkani 14.94% (95% CI: 14.93% - 14.95%), Gbeke 10.34% (95% CI: 10.33% - 10.35%), Marahoue 13.79% (95% CI: 13.78% - 13.80%), Poro 8.50% (95% CI: 8.49% - 8.51%), and Tchologo 11.83% (95% CI: 11.82% - 11.84%).The most sensitive diagnostic method used was the polymerase chain reaction (PCR). The species of trypanosomes diagnosed were Typanosoma vivax 4.99% (95% CI: 4.97% - 5.01%), T. congolense 1.51% (95% CI: 1.49% - 1.52%), and T. brucei 0.61% (95% CI: 0.59% - 0.62%). Despite some variation, the prevalence of bovine trypanosomiasis in Côte d'Ivoire caused mainly by T. vivax has increased in the years between 1977 and 2017. Efforts to control tsetse and other mechanical vectors should also be put in place to minimize its transmission. CONTRIBUTION: The authors studied the prevalence of bovine trypanosomiasis using the systematic review method and MA in order to determine the status of research on this disease in Côte d'Ivoire

ABSTRACT We present the elucidation mechanism of arsenite removal with slags through the evaluation of five materials: A1, C1, N1 (steel industry), M1 (lead industry), and M2 (iron industry), all of them with different surface areas pore diameter, and chemical and mineralogical composition. The slags were physically characterized, determining surface area (1.6 to 10 m2/g) and zero charge point (5.5); chemically by X ray fluorescence (XRF) mainly identifying Si, Ca and Fe, and the release of potentially toxic elements by leaching at different pH´s (5, 7 and 9) was ruled out. The mineralogy determined by X ray difraction (XRD) showed iron compounds. The removal of arsenite was evaluated at laboratory level by means of a 2k experimental design in synthetically contaminated samples. Agitation time, amount of slag and initial concentration of arsenite were evaluated. The optimal removal conditions were: 250 mg of slag, 10 mg/L of arsenite, and agitation time of 60 min. The C1 slag removed more than 90 % of the initial arsenite, and the proposed fixation mechanism could be a chemisorption at heterogeneous sites, as well as through intraparticle diffusion. XRD and infrarred (IR) spectroscopy analyses of the slag after arsenic fixation showed that there is a direct interaction of arsenite with iron.

RESUMEN En este trabajo se busca elucidar el mecanismo de remoción de arsenito con escorias mediante la evaluación de cinco materiales: A1, C1, N1 (industria del acero), M1 (industria del plomo) y M2 (industria del hierro), todos ellos con diferente área superficial, tamaño de poro, y composición química y mineralógica. Las escorias se caracterizaron físicamente, determinándose su área superficial (1.6 a 10 m2/g), tamaño de poro (6.5 a 16.8 nm) y punto de carga cero (5.5); químicamente por fluorescencia de rayos X (FRX), identificándose mayoritariamente Si, Ca y Fe, y se descartó la liberación de elementos peligrosos por lixiviación a distintos pH (5, 7 y 9). La mineralogía determinada por difracción de rayos X (DRX) muestra compuestos de hierro. La remoción de arsenito se evaluó mediante un diseño experimental 2k en muestras contaminadas sintéticamente en el laboratorio. Se evaluaron el tiempo de agitación, la cantidad de escoria y la concentración inicial de arsenito. Las condiciones óptimas de remoción fueron: 250 mg de escoria, 10 mg/L de arsenito y 60 min de agitación. La escoria C1 removió más del 90 % del arsenito inicial y se sugiere que la fijación ocurre por quimisorción en sitios heterogéneos del material, así como a través de la difusión intrapartícula. Los análisis de espectroscopía de DRX e infrarroja (IR) de la escoria después de fijar arsénico, muestran que existe una interacción directa del arsenito con el hierro.Palabras clave: arsenito, escorias, adsorción, quimisorción, remoción.

RESUMO: A variabilidade genética é a base para o progresso genético em café. Este estudo teve como objetivo, avaliar o potencial de caracteres morfoagronômicos e anatômicos foliares em estudos de variabilidade genética entre cultivares de Coffea canephora. Dez genótipos foram distribuídos em um experimento seguindo delineamento em blocos ao acaso com três repetições. Foram detectadas diferenças significativas entre os genótipos pelo teste F (P < 0,05) para 13 dos 15 caracteres avaliados. Esses resultados evidenciaram a heterogeneidade entre as cultivares estudadas, o que é essencial para a composição da base genética e avanço dos programas de melhoramento. O teste de Scott e Knott detectou as diferenças entre os genótipos, separando-os em quatro grupos. Os caracteres anatômicos foliares apresentaram as maiores variações. Cinco, dentre os sete caracteres anatômicos foliares, apresentaram estimativas de herdabilidade superiores a 80% com destaque para a densidade estomática (95,69%) e comprimento do poro estomático (92,72%). Correlações positivas foram observadas entre caracteres morfoagronômicos e anatômicos foliares. A análise de agrupamento, considerando a distância de Mahalanobis como medida de dissimilaridade (D²), apontou a distinção de dois grupos de genótipos. A inclusão de caracteres anatômicos foliares na caracterização de genótipos de C. canephora pode auxiliar os melhoristas de plantas na melhor discriminação entre genótipos e maior segurança na seleção de clones para geração de novas cultivares.

ABSTRACT: Genetic variability is the basis for coffee genetic breeding. This study evaluated the potential of leaf anatomy and morpho-agronomic traits in studies of genetic variability in C. canephoracultivars. Ten genotypes were distributed in randomized block designs with three replicates. Significant differences among genotypes were detected by F-test (P < 0.05) for 13 of 15 evaluated traits. These results evidenced the heterogeneity of the studied cultivars, which is essential in composition of genetic basis in breeding programs. The Scott-Knott test detected variability among genotypes, grouped into up to four mean groups. Leaf anatomy traits presented the largest variations. Five out of seven leaf anatomy traits presented heritability higher than 80%, with emphasis on stomatal density (95.69%) and stomatal pore length (92.72%). Positive correlations were observed among morpho-agronomic and anatomic traits. Cluster analysis used the Mahalanobis general distance (D2) as a measure of genetic dissimilarity and divided the genotypes into two distinct groups. The inclusion of leaf anatomic traits to characterize C. canephoragenotypes may assist plant breeders with better genetic discrimination and with greater security in plant selection when composing cultivars.
