ABSTRACT Purpose Varicocele is a condition known to cause damage to seminal parameters and sperm function. Furthermore, it has been hypothesized that the varicocele effect on fertility is time-dependent; however, little is known about the consequences of its establishment time on reproductive organs and/or sperm function. This study aimed to evaluate the effect of the duration of experimental varicocele on reproductive organs, sperm parameters, and sperm function. Materials and Methods Varicocele induction surgeries were performed in Wistar rats aged 40 or 100 days old. At 160-day-old, analyses were performed, including biometry of reproductive organs (prostate, seminal vesicles, epididymis, and testis), sperm parameters (vitality, morphology, and motility), and sperm function tests (nuclear DNA integrity, acrosome integrity, and mitochondrial activity). Results The analysis of the biometry of reproductive organs showed no differences between distinct ages in which varicocele was induced. The total abnormal sperm morphology was bigger in animals with varicocele induced to 100 days old than in animals with varicocele induced to 40 days old. Regarding nuclear DNA integrity, animals of varicocele induced to 100 days old showed worse results compared to animals of varicocele induced to 40 days old. Other parameters analyzed showed no differences between varicocele groups. Conclusion In this study conducted on rats, we conclude that varicocele adversely affects sperm, particularly its function. However, we did not observe a negative progressive effect on sperm.

Abstract Pilón (Hyeronima alchorneoides) is one of the native tree species with the greatest potential for cultivation in Costa Rica. At a national level, there is research on its silvicultural management, tree improvement, wood quality and others. However, there is a lack of an updated and complete technological guide for this species. Therefore, there is a need to compile and systematize the generated knowledge in recent years about this species, with the purpose of improving technical assistance to the producer or investors. One of the main issues and needs are the availability of reliable growth models for diameter and total height for this species. A database with more than 255 plots was used for the diameter growth and more than 150 plots recording the total height. The growth function fitted for the diameter was dap=1,4145+2,1381*Edad-0,0364*(Edad)^2. Meanwhile, for total height the fitted model was Ht=e^((3,9090-3,5510*√(1/Edad)), both models have a bias estimation of 20% for diameter and 18% for total height.

Resumen El pilón (Hyeronima alchorneoides) es una de las especies forestales nativas de mayor potencial de cultivo en Costa Rica. A nivel nacional, existen investigaciones en temas como manejo silvicultural, mejoramiento genético, calidad de la madera, entre otras. Sin embargo, no existe un paquete tecnológico actualizado y completo para esta especie. Por lo que surge la necesidad de actualizar los modelos de crecimiento de diámetro y altura para esta especie. Para este estudio se utilizó una base de datos con más de 255 parcelas para el crecimiento diamétrico y más de 150 para la altura total. La función de crecimiento para el diámetro ajustada fue dap=1,4145+2,1381*Edad-0,0364*(Edad)^2, mientras que, para la altura total, el modelo ajustado fue Ht=e^((3,9090-3,5510*√(1/Edad)), Ambos modelos registraron un sesgo de un 20% para la estimación del diámetro y un 18% para la estimación de la altura total.

Resumen OBJETIVO: Comparar las concentraciones de hemoglobina en embarazadas con anemia por deficiencia de hierro que recibieron un tratamiento intermitente en comparación con el continuo de 200 mg de sulfato ferroso por vía oral. Además, comparar la frecuencia de efectos secundarios del tratamiento intermitente con el continuo. MATERIALES Y MÉTODOS: Ensayo clínico, aleatorizado, no cegado, efectuado en la Unidad Médica de Alta Especialidad Hospital de Ginecoobstetricia 4 Luis Castelazo Ayala, IMSS, en pacientes de 18 a 35 años atendidas entre los meses de enero a marzo del 2023 con 30 o más semanas de embarazo, diagnóstico de anemia ferropénica (definida operativamente solo con una biometría hemática inferior a 11 g/dL, con hipocromía y microcitosis), sin antecedentes de enfermedad crónico-degenerativa.

ABSTRACT: This study recorded the physicochemical properties of the marula fruits, the biometry and breaking the dormancy in the marula seeds. Using 200 ripe fruits, the physicochemical characterization was done. From a random sample of 400 seeds, an assessment of the biometrics was performed, and the weight, length, width and thickness of the fruits and seeds were evaluated. Two experiments were conducted to study dormancy breaking using pre-germination treatments, which included immersing the marula seeds five times (0, 15, 30, 45 and 60 minutes) in concentrated sulfuric acid (96%) and water, at 65 ºC temperature. The control was time zero, using plain distilled water, with 25 seeds per treatment and four replications. The marula fruits revealed average values of 21.65 ± 3.44 g, 35.5 ± 2.38 and 34.8 ± 2.73, respectively, for weight, diameter and length. The soluble solids (SS), Hydrogenonic Potential (pH), titratable acidity (AT) and ratio (AT/SS) were 14.74 ± 1.0º Brix, 3.93 ± 0.49 pH, 0.63 ± 0.22 and 27.07 ± 12.10, respectively. For the weight of one thousand seeds, the average value was 3.576 ± 188.4 g. The mean values for the dimensions of the width, length and diameter of the seeds were 22.9 ± 2.11; 23.7 ± 2.04; and 14.9 ± 2.09 mm, respectively. The physiological quality of these seeds was enhanced by immersing the seeds from freshly picked fruits in sulfuric acid for a maximum of 30 minutes and storing them for six months.

ABSTRACT Two investigations were developed. The first experiment was to determine the metabolizability of Moringa (Moringa oleifera) leaf meal. 120 slow-growing, 21-day-old chickens were used. The experimental period was seven days, four for adaptation to diets and three for collection of excreta. The Moringa leaf presented values for apparent metabolizability coefficients of dry matter, crude protein, crude energy and neutral detergent fiber, as well as apparent metabolizable energy and corrected metabolizable energy for a nitrogen balance, of 49.77%, 44.48%, 46.26% and 53.02%, and 2,334 kcal/kg, 2,159 kcal/kg respectively. The second experiment was to evaluate the inclusion of Moringa leaf meal in the diets of two hundred and forty slow-growing chickens from one to 80 days of age on performance, carcass characteristics, biometrics of digestive organs and meat color. The experimental design was completely randomized with four treatments (0.75%; 1.50%; 2.25% and 3.00% inclusion of the Moringa leaf), six repetitions and ten chickens per experimental unit; the inclusion levels of the Moringa leaf did not influence (p> 0.05) feed intake, weight gain, feed conversion, final weight at 30, 60 and 80 days, carcass, noble cut yields and meat color. The inclusion of Moringa leaf meal can be used up to the 3% level in slow-growing chicken diets, without affecting the productive performance of these animals. developed oleifera 12 slowgrowing, slowgrowing slow growing, growing 21dayold dayold 21 day old excreta matter protein fiber balance 4977 49 77 49.77% 4448 44 48 44.48% 4626 46 26 46.26 5302 53 02 53.02% 2334 2 334 2,33 kcalkg kcal kg 2159 159 2,15 respectively 8 characteristics color 0.75% 075 0 75 (0.75% 1.50% 150 1 50 225 25 2.25 300 3 00 3.00 leaf, , leaf) unit p> p (p 0.05 005 05 intake gain conversion 30 6 animals 497 4 7 49.77 444 44.48 462 46.2 530 5 53.02 233 33 2,3 215 15 2,1 0.75 07 (0.75 1.50 22 2.2 3.0 0.0 49.7 44.4 46. 53.0 23 2, 0.7 (0.7 1.5 2. 3. 0. 49. 44. 53.

ABSTRACT We present a case of a patient complaining of monocular diplopia due to a decentered ablation after LASIK. The patient underwent a wavefront-guided retreatment, which resulted in an epithelial ingrowth complication. Additionally, the patient developed cataract, with cataract surgery requiring reliable biometric measurements. Therefore, we opted for corneal treatment and corneal surface regularization. Although we attempted to lift the flap and wash the interface initially, the procedure proved unsuccessful, thereby necessitating immediate flap amputation. Once the corneal surface was regularized in the seventh postoperative month, transepithelial photorefractive keratectomy was successfully performed to homogenize the ocular surface, thereby significantly improving the patient’s corrected visual acuity and resolving monocular diplopia. The surface and corneal curvature stabilized by the fifth month after the procedure. Phacoemulsification was then performed along with the implantation of a toric monofocal lens, which was selected using an appropriate formula, resulting in an excellent uncorrected visual acuity.

Abstract The objective of this work was to determine the optimal day for pollinating the flowers of the San Andreas strawberry cultivar after flower anthesis. The study was carried out in two periods (summer and fall), on a commercial farm. A total of 12 flower buds were monitored and photographed in each of the following 11 treatments: manual cross-pollination (MCP) on the first to fifth day after flower anthesis (MCP1 to MCP5), natural pollination (NP) on the first to fifth day after flower anthesis (NP1 to NP5), and self-pollination. After pollination, the flowers were bagged until the development and maturation of the flower receptacle. Subsequently, the fruits were harvested, quantified, and subjected to evaluations to determine biometry, degree of deformity, and the percentage of fertilized achenes. The flowers of the San Andreas cultivar remain open during five days, when the beginning of the development of the flower receptacle can already be observed. The optimal days for strawberry flower pollination through MCP or NP are the first two days after anthesis. summer fall, fall , fall) farm 1 treatments crosspollination cross (MCP MCP1 MCP5, MCP5 MCP5) (NP NP1 NP5, NP5 NP5) selfpollination. selfpollination self pollination. self-pollination Subsequently harvested quantified biometry deformity achenes observed

ABSTRACT This document on myopia control is derived from a compilation of medical literature and the collective clinical expertise of an expert committee comprising members from the Brazilian Society of Pediatric Ophthalmology and the Brazilian Society of Contact Lenses and Cornea. To manage myopia in children, the committee recommends corneal topography and biannual visits with cycloplegic refraction, along with annual optical biometry. For fast-progressing myopia, biannual biometry should be considered. Myopic progression is defined as an annual increase in spherical equivalent greater than 0.50 D/year or in axial length greater than 0.3 mm (until 10 years old) or 0.2 mm (above 11 years). The proposed treatments for myopia progression include environmental control, low concentration atropine, defocus glasses, contact lenses, or Ortho-K lenses, and combinations of these methods may be necessary for uncontrolled cases. Treatment should be sustained for at least 2 years. This document serves as a comprehensive guideline for diagnosing, treating, and monitoring pre-myopic and myopic children in Brazil.

Abstract The biometric differences between fruits and seeds are useful characteristics that can provide important data for the investigation and preservation of the species and may be linked to environmental and genetic influences. In this sense, considering the importance of this species and the need for conservation, the objective was to carry out physical characterization of the fruits and seeds of Hymenaea martiana as well as to determine the seed imbibition curve. The experiment was conducted at the Seed Analysis Laboratory at the Agricultural Sciences Center at the Federal University of Paraíba in Areia, PB. The evaluations carried out were as follows: biometry of fruits and seeds, number of seeds per fruit, colorimetry of fruits and seeds, percentage of damaged seeds, weight of a thousand seeds, seed water content, mass and imbibition curve. The biometric data were subjected to descriptive analysis to determine the minimum, maximum, average value, standard deviation, asymmetry, and kurtosis of the fruits and seeds. In terms of the biometric characteristics of the fruits and seeds of H. martiana, there was a marked variation, with average fruit lengths of 90.28 mm, widths of 46.83 mm, thicknesses of 34.69 mm, weights of 65.86 g and four seeds per fruit. The average length, width, thickness and weight of the seeds were 23.75 mm, 18.34 mm, 12.71 g and 4.13 g, respectively. The fruits were darker than the seeds, and both the fruits and seeds had red tones.

ABSTRACT Objective To evaluate intraocular lens power calculation and postoperative refractive errors in patients with high myopia undergoing cataract surgery, comparing predicted target refraction and actual postoperative refraction measured 30 days after surgery with SRK/T formula. Methods This retrospective analysis comprised 39 eyes of 31 patients undergoing cataract surgery through phacoemulsification with in-the-bag IOL implantation. Axial length was measured by partial coherence interferometry or immersion ultrasound biometry, with measurements greater than 26 mm and preoperative myopia greater than -6.0 D Manifest refraction was performed at the 1-month postoperative visit, and the spherical equivalent was analyzed. Results After analysis of 39 eyes of 31 patients undergoing cataract surgery with a mean axial length of 30.4 (standard deviation of 2.2) mm, the mean preoperative refractive spherical equivalent was -15.6 (standard deviation of 7.6) D, ranging from -24.0 to -13.4 D. At 30 days postoperatively, the mean spherical equivalent was -0.35 (standard deviation of 1.1) D, ranging from -2.4 to 2.50 D. Conclusion We encountered a correlation between the absolute refractive error and the dioptric power of the intraocular lens. Against expectations, in our study, ultrasound biometry yielded better results than the optical biometer device, probably due to the small number of patients undergoing optical biometry, suggesting that well-performed immersion biometry can still produce satisfactory results. 3 SRKT SRK T formula inthebag bag implantation 2 6.0 60 6 0 -6. 1month month 1 visit analyzed 304 4 30. standard 2.2 22 15.6 156 15 -15. 7.6 76 7 24.0 240 24 -24. 13.4 134 13 -13. postoperatively 0.35 035 35 -0.3 1.1 11 2.4 -2. 250 50 2.5 expectations study device wellperformed well 6. -6 2. 15. -15 7. 24. -24 13. -13 0.3 03 -0. 1. -2 25 5 - -1 0. -0

RESUMO Objetivo Avaliar os cálculos de potência da lente intraocular e os erros refrativos pós-operatórios em pacientes com alta miopia submetidos à cirurgia de catarata, comparando a refração-alvo prevista e a refração pós-operatória real medida 30 dias após a cirurgia com a fórmula SRK/T. Métodos Esta análise retrospectiva incluiu 39 olhos de 31 pacientes com cirurgia de catarata de facoemulsificação não complicada com implantação de lente intraocular na bolsa. Os comprimentos axiais foram medidos por biometria de coerência óptica ou ultrassônica (imersão), com medidas de axial length (AL) maiores que 26 mm em pacientes com miopia maior que -6.0 D. A refração manifesta foi realizada na consulta pós-operatória de 1 mês, e o equivalente esférico foi analisado. Resultados Após análise de 39 olhos de 31 pacientes submetidos à cirurgia de catarata com AL médio de 30,4 (desvio-padrão de 2,2) mm, o equivalente esférico refrativo médio pré-operatório foi de -15,6 (desvio-padrão de 7,6) D, variando de -24,0 a -13,4 D. Aos 30 dias de pós-operatório, o equivalente esférico médio foi de -0,35 (desvio-padrão de 1,1) D, variando de -2,4 a 2,50 D. Conclusão Encontramos uma correlação entre o erro refrativo absoluto e o poder dióptrico da lente intraocular. Contrariando as expectativas, em nosso estudo, a biometria ultrassônica apresentou melhores resultados que o biômetro óptico, provavelmente devido ao pequeno número de pacientes submetidos à biometria óptica, sugerindo que a biometria de imersão bem executada ainda pode produzir resultados satisfatórios. pósoperatórios pós operatórios refraçãoalvo alvo pósoperatória operatória 3 SRKT SRK T SRK/T bolsa imersão, , (imersão) (AL 2 6.0 60 6 0 -6.

BACKGROUND: Understanding the relationship between biometric and structural changes in childhood myopia is necessary to effectively manage myopia progression AIM: To determine the relationship between ocular biometry, fovea and sub-fovea choroidal thickness in school-aged children with myopia of Nigerian descent SETTING: Abuja, Nigeria METHODS: This study involved 189 children (117 girls and 72 boys), and myopia was defined as cycloplegic spherical equivalent refraction (SER) of ≤ −0.50 D. Keratometry values, biometry data, fovea and sub-foveal choroidal thickness (SFChT) values were obtained from medical records retrospectively and analysed RESULTS: The median age was 13 years (interquartile range [IQR]: 5). The median SER, fovea and SFChTs were −2.63 D (IQR: 3.38), 249 μm (IQR: 118) and 225 μm (IQR: 341), respectively. Male children had flatter corneas, thicker fovea and thinner SFChT compared to female children. The vitreous chamber and axial length were longer and sub-fovea choroid was thinner in children with high myopia. There was a weak but significant positive correlation between myopia and sub-fovea choroidal thickness (r = 0.270 respectively, P < 0.01). A moderate negative correlation was found between myopia and vitreous chamber depth (r = −0.536, P < 0.001), and a strong negative correlation was found between myopia and axial length (r = −0.706, P < 0.001 CONCLUSION: Myopia in school-aged Nigerian children is associated with sub-fovea choroidal thinning, increased vitreous chamber depth and axial elongation CONTRIBUTION: This study provides data on the relationship between ocular biometry, fovea and sub-foveal choroidal thickness in school-aged Nigerian children with myopia

Resumo A marula (Sclerocarya birrea) pertencente à família Anacardiaceae, é originária do bioma das savanas da África do Sul e da região da África oriental. É uma das árvores nativas mais valorizadas do sul da África por possuir propriedades medicinais e nutricionais de grande valor, entretanto existe um entrave na sua produção que é a dormência das sementes. Assim, objetivou-se com este trabalho avaliar a influência do tempo de armazenamento na superação da dormência e na qualidade fisiológica de sementes de marula. O delineamento experimental utilizado foi o inteiramente casualizado, utilizando-se 400 sementes distribuídas aleatoriamente em 4 repetições de 100 sementes para analise biométrica. Para avaliação da qualidade fisiológica e superação da dormência das sementes os tratamentos consistiram em cinco períodos de armazenamento: 10 dias (testemunha); e 184; 244; 306; 367 e 428 dias após o colheita, com quatro repetições de 25 sementes por tratamento. Recomenda-se, o armazenamento das sementes de marula durante 367 dias após a colheita em condições ambientais (26±2 °C), por apresentarem melhor qualidade fisiológica.

Abstract Marula (Sclerocarya birrea) is a species of the family Anacardiaceae, native to the savanna biome in South and East Africa. It is among the most valued native trees of southern Africa due to its medicinal and nutritional properties; however, the dormancy of its seeds makes the production of marula difficult. Thus, the objective of this work was to evaluate the effect of storage times on dormancy breaking and physiological quality of marula seeds. A completely randomized experimental design was used, with four 100-seed replications for evaluating seed biometry. Physiological quality and dormancy breaking were evaluated through treatments consisted of five storage periods: 10 (control), 184, 244, 306, 367, and 428 days after harvest, with four 25-seed replications per treatment. Storing marula seeds under room conditions (26±2 °C) for 367 days after harvest is recommended for a better physiological quality of the seeds.

ABSTRACT The gestation biometrics of the alpaca (Vicugna pacos) are described. The abdominal diameter was determined monthly from 10 pregnant alpacas. In addition, uterus of 49 pregnant alpacas were collected from the Maranganí herd (Cusco, Peru) and classified by gestational age known as mating date (every 30 days from day 30 to 330 [± 15 days]). Gravid uteri were weighed and measured, allantoic and amniotic fluid was removed and measured, and fetal weight and length were determined. The results indicate a slight increase in abdominal diameter until the end of gestation, the fetus gradually increases its weight as gestation progresses, being greater from the sixth month onwards. The total length of the fetus increases from month nine. The amniotic fluid represents less than 18% of the volume of the allantoic fluid, both fluids have low volumes. An increase in fluids could be observed towards month fivem a decrease until month nine, and a subsequent increase until the delivery date.

RESUMEN En el presente estudio se describe la biometría de la gestación de la alpaca (Vicugna pacos). Se determinó el diámetro abdominal en forma mensual de 10 alpacas gestantes. Además, se colectaron 49 úteros grávidos del camal de Maranganí (Cusco, Perú) y fueron clasificados por edad gestacional conocida mediante fecha de empadre (cada 30 días a partir del día 30 al día 330 [± 15 días]). Los úteros grávidos fueron pesados y medidos, se midieron los fluidos alantoideo y amniótico, y se determinó el peso y la longitud del feto. Los resultados indican un ligero incremento del diámetro abdominal hasta el final de la gestación, el feto incrementa su peso gradualmente a medida que avanza la gestación, siendo mayor a partir del sexto mes. El largo total del feto se incrementa desde el noveno mes. El líquido amniótico representa menos del 18% del volumen del líquido alantoideo, ambos fluidos presentan bajos volúmenes. Se pudo observar un incremento de los fluidos hacia el quinto mes, una disminución hasta el noveno mes, y posterior incremento hasta la fecha de parto.

ABSTRACT To demonstrate by dissection of anatomical specimens and prenatal ultrasonographic images of the fetal heart the presence of the cardiac fulcrum as a fixation structure supporting the helical myocardial band. Six hearts of fetuses between 20-24 weeks of gestational age resulting from spontaneous abortions were dissected, finding the cardiac fulcrum in the proximity of the aorta and connections with myocardial fibers. In 50 singleton pregnancies with fetuses between 18-37 weeks of gestation, fetal cardiac ultrasonography was used to obtain 2D, Doppler, color and three-dimensional modalities, STIC, HD Flow and speckle tracking, images, fulcrum measurements and its kinetics. With the described strategy, the presence of the cardiac fulcrum or myocardial lever was identified and demonstrated, establishing its anatomical characteristics, connections with myocardial fibers of the cardiac loop and the biometry according to gestational age. A hypothesis on the biomechanics or kinetics of the fulcrum during the cardiac cycle is formulated. In order for the heart to fulfill its function as an aspirating and impelling pump, it must have a support point, a lever or fulcrum, which constitutes a sort of muscle-tendon unit. This lever presents mixed displacements during myocardial torsion and detorsion. Its diameters increase progressively as gestation advances.

RESUMEN Demostrar mediante la disección de piezas anatómicas y de imágenes ultrasonográficas prenatales del corazón fetal la presencia del fulcro cardíaco como estructura de fijación que sirve de soporte a la banda miocárdica helicoidal. Se disecaron 6 corazones de fetos entre las 20 y 24 semanas de edad gestacional productos de abortos espontáneos, logrando encontrar el fulcro cardíaco en la proximidad de la aorta y conexiones con fibras miocárdicas. En 50 embarazos simples con fetos entre las 18 y 37 semanas de gestación, mediante ultrasonografía cardíaca fetal se obtuvieron las modalidades 2D, Doppler, color y tridimensión, STIC, HD Flow y speckle tracking, imágenes, medidas del fulcro y su cinética. Con la estrategia descrita se identificó y demostró la presencia del fulcro cardíaco o palanca miocárdica, estableciendo sus características anatómicas, conexiones con fibras miocárdicas del asa cardíaca y la biometría según la edad gestacional. Se formula una hipótesis sobre la biomecánica o cinética del fulcro durante el ciclo cardíaco. Para que el corazón cumpla su función de bomba aspirante e impelente debe poseer un punto de apoyo, una palanca o fulcro, que constituye una especie de unidad músculo-tendinosa. Dicha palanca presenta desplazamientos mixtos durante la torsión y detorsión del miocardio. Sus diámetros aumentan progresivamente a medida que avanza la gestación.

ABSTRACT Biometric seed analysis can be used to characterize and differentiate forest species. However, forest species are generally studied using manual methods such as measurements with a digital caliper, which provides a limited amount of information on plant morphological characteristics, whereas agronomic species are analyzed using expensive and often inaccessible equipment. Thus, the objective of the present study was to demonstrate that seed image analysis and processing tools can help characterize and differentiate Brazilian forest species. For this purpose, the seeds of 155 forest species belonging to 42 families were photographed and analyzed to extract data on their morphometric descriptors using a new methodological approach. A total of 18 characteristics were assessed, namely eight dimensions, four shape characteristics, and six color characteristics. A set of approximately 1.827 million data was extracted from 101,521 seed images. Digital image processing efficiently characterized the studied seeds and the obtained characteristics allowed us to differentiate between species, including those belonging to the same botanical family and genus. Therefore, seed image analysis using the proposed methodology can be used to characterize, differentiate, and automatedly identify forest species in Brazil.

RESUMO A análise biométrica de sementes contribui para a caracterização e diferenciação de espécies florestais. Entretanto, os estudos com espécies nativas geralmente utilizam métodos manuais como o paquímetro digital, o qual extrai uma quantidade limitada de características, enquanto espécies agronômicas dispõem de equipamentos caros e pouco acessíveis. Assim, o objetivo deste trabalho é demonstrar que ferramentas de análise e processamento de imagens de sementes podem auxiliar na caracterização e diferenciação de espécies nativas brasileiras. Para isso, sementes de 155 espécies nativas, distribuídas em 42 famílias botânicas foram fotografadas e analisadas para extração de descritores morfométricos por meio de uma nova abordagem metodológica. Um total de 18 características foram geradas, sendo oito para dimensões, quatro para formato, e seis para cor. Um conjunto de aproximadamente 1,827 milhões de dados foram obtidos a partir 101.521 imagens de sementes. O processamento digital de imagens foi eficiente para a caracterização das sementes nativas, e as características utilizadas permitiram diferenciar as espécies, inclusive àquelas que estão contidas na mesma família botânica e gênero. Portanto, a análise de imagens de sementes pela metodologia proposta contribui para a caracterização, diferenciação e automatização na identificação de espécies florestais nativas do Brasil.
