Abstract The investigation of cultivation and management techniques that take into account behaviour and animal welfare becomes important due to their direct relationship with animal performance. This study aimed to classify juvenile Oreochromis niloticus by personality and compare their performance at exploration and competition tasks. The new object test was used to select bold and shy animals, which were then tested to see which first approached an object. The food competition test involved placing three feed pellets inside a cylinder and measuring the time taken until the pellet was eaten. The new object test found bold animals with a shorter mean time to approach the object than shy animals approaching 65% of the first object when compared to shy. The food competition test found that the bold animals ingested the first pellet more times and with a shorter average time of ingestion than shy animals, no difference in the second intake, whereas the results for the third were same as those for the first. Shy animals had higher intake of the second pellet. Bold animals explored their environment faster in both challenges, while shy individuals exhibited ability to learn from the challenges imposed in the study.

Brain glucose hypometabolism and neuroinflammation are early pathogenic manifestations in neurological disorders. Neuroinflammation may also disrupt leptin signaling, an adipokine that centrally regulates appetite and energy balance by acting on the hypothalamus and exerting neuroprotection in the hippocampus. The Goto-Kakizaki (GK) rat is a non-obese type 2 diabetes mellitus (T2DM) animal model used to investigate diabetes-associated molecular mechanisms without obesity jeopardizing effects. Wistar and GK rats received the maintenance adult rodent diet. Also, an additional control group of Wistar rats received a high-fat and high-sugar diet (HFHS) provided by free consumption of condensed milk. All diets and water were provided ad libitum for eight weeks. Brain glucose uptake was evaluated by 2-deoxy-2-[fluorine-18] fluoro-D-glucose under basal (saline administration) or stimulated (CL316,243, a selective β3-AR agonist) conditions. The animals were fasted for 10-12 h, anesthetized, and euthanized. The brain was quickly dissected, and the hippocampal area was sectioned and stored at -80°C in different tubes for protein and RNA analyses on the same animal. GK rats exhibited attenuated brain glucose uptake compared to Wistar animals and the HFHS group under basal conditions. Also, the hippocampus of GK rats displayed upregulated leptin receptor, IL-1β, and IL-6 gene expression and IL-1β and the subunit of the transcription factor NF-κB (p-p65) protein expression. No significant alterations were detected in the hippocampus of HFHS rats. Our data indicated that a genetic predisposition to T2DM has significant brain deteriorating features, including brain glucose hypometabolism, neuroinflammation, and leptin signaling disruption in the hippocampal area.

ABSTRACT Fusarium head blight, also known as fusariosis, is caused by a fungus called Fusarium graminearum that produces the mycotoxin deoxynivalenol (DON). This toxin causes problems to human and animal health. Ammonia gas has been shown to be effective in deactivating mycotoxins. The objectives of this study were to evaluate the effectiveness of ammonia gas in the deactivation of DON in wheat grains, the effect of this treatment on its protein composition and the toxicity in rats fed with ammoniated wheat grains. Wheat samples were exposed to ammonia gas at concentrations of 0% (Control), 0.5%, 1% and 1.5%. It was observed that ammonia gas was effective in deactivating DON at concentrations of 1% and 1.5%. There was no difference in crude protein observed in the bromatological analysis of treated wheat grains in relation to the control. Regarding the toxicity of wheat grains treated with ammonia in the feeding of Wistar rats (Rattus norvegicus), no histopathological alterations were observed in the liver, kidneys, intestine and in the hematological profile. The results of this study demonstrated that the treatment of wheat with ammonia gas can contribute to the deactivation of DON without compromising its protein composition and animal health.

RESUMO A giberela, também conhecida como fusariose, é causada por um fungo chamado Fusarium graminearum, que produz a micotoxina desoxinivalenol (DON). Essa toxina gera problemas à saúde humana e animal. O gás amônia demonstrou ser eficaz na desativação das micotoxinas. Os objetivos deste estudo foram avaliar a eficácia do gás amônia na desativação do DON em grãos de trigo contaminados naturalmente, o efeito desse tratamento na sua composição proteica e a toxicidade em ratos alimentados com os grãos de trigo amonizados. Amostras de trigo foram expostas ao gás amônia nas concentrações de 0% (controle), 0,5%, 1% e 1,5%. Observou-se que o gás amônia foi eficaz na desativação do DON na concentração de 1% e 1,5%. Não houve diferença na proteína bruta observada na análise bromatológica dos grãos de trigo tratados em relação ao controle. Quanto à toxicidade dos grãos de trigo tratados com amônia fornecidos aos ratos Wistar (Rattus norvegicus), não foram observadas alterações histopatológicas do fígado, dos rins e do intestino e no perfil hematológico. Os resultados deste estudo demonstraram que o tratamento de trigo com gás amônia pode contribuir na desativação do DON sem comprometer sua composição proteíca e a saúde dos animais.

To investigate the time-dependent effects of traditional risk factors on functional disability in all-cause mortality post-stroke, we evaluated data from a long-term stroke cohort. Baseline cerebrovascular risk factors (CVRF) and functionality at 1 and 6 months were evaluated in survivors from a prospective stroke cohort using the modified Rankin scale (m-RS), which classifies participants as improvement of disability, unchanged disability (at least moderate), and worsening disability. Cox regression models considering baseline risk factors, medication use, and functionality 6 months after stroke were fitted to identify their time-dependent effects up to 12 years of follow-up. Adjusted hazard ratios (HR) with 95% confidence intervals (CI) are presented. Among 632 survivors (median age 68, 54% male, 71% first-ever episode), age and functional disability (unchanged and worsening) 6 months after ischemic stroke had time-dependent effects on all-cause mortality risk up to 12 years of follow-up. The most impacting risk factors were unchanged (at least moderate) (HR, 2.99; 95%CI: 1.98-4.52) and worsening disability (HR, 2.85; 95%CI: 1.26-6.44), particularly in the first two years after a stroke event (Time 1: ≥6 mo to <2.5 y). Worsening disability also impacted mortality in the period from ≥2.5 to <7.5 years (Time 2) of follow-up (HR, 2.43 (95%CI: 1.03-5.73). Other baseline factors had a fixed high-risk effect on mortality during follow-up. Post-stroke and continuous medication use had a fixed protective effect on mortality. Functional disability was the main contributor with differential risks of mortality up to 12 years of follow-up.

RESUMO Este artigo tem por objetivo colocar a dança no centro da análise histórica da tragédia ateniense do século V a.C. Para tanto, é proposta uma trajetória que parte da cultura da performance, passa pela cultura dos festivais, pela dança do coro e pelo ensinamento do velho sátiro bêbado, até chegar na revisão dos conceitos de opsis e psuchagôgia, presentes na Poética de Aristóteles. Desse modo, busca-se compreender como a performance cívico-ritual dos atores-cantores-dançarinos gregos antigos, a partir da criação de figuras de movimento, era também um ato de evocação das almas no contexto de uma festividade pública.

ABSTRACT The purpose of this article is to place dance at the center of the historical analysis of Athenian tragedy of the 5th century BC. To do so, a trajectory is proposed that begins with the culture of performance, passes through the culture of festivals, the dance of the chorus and the teaching of the old drunken satyr, and then reviews the concepts of opsis and psuchagôgia in Aristotle's Poetics. Thus, the objective is to understand how the ritual-civic performance of the ancient Greek actors-singers-dancers, based on the creation of figures of movement, was also an act of evoking souls in the context of a public festivity.

RÉSUMÉ Cet article vise à placer la danse au centre de l'analyse historique de la tragédie athénienne du Ve siècle av. JC . Pour cela, une trajectoire est proposée qui part de la culture de la performance, passe par la culture de fêtes, par la danse du chœur et par l'enseignement du vieux satyre ivre, jusqu'à arriver à la révision des concepts d'opsis et de psuchagôgia, présents dans la Poétique d'Aristote. De cette manière, c’est cherché à comprendre comment la performance civique-rituelle des acteurs-chanteurs-danseurs grecs antiques, à partir de la création de figures de mouvement, était aussi un acte d'évocation des âmes dans le cadre d'une fête publique.

Abstract The main objective of this study is to propose different probabilistic models for adjusting the trend component, since it significantly influences the quality of the spatio-temporal interpolation of rainfalls. We used the monthly total precipitation data of the São Francisco River Basin (SFRB) for the period of 31 years, 1989–2019. The SFRB occupies 8% of the whole Brazilian territory, mostly located in the Northeast Brazilian region. For the trend component, we propose the fitted GAMLSS models by comparing different probability distribution families, which in most cases include the characteristics of these data. The results indicate the existence of a spatio-temporal pattern of the residues obtained from the adjustment of the trend with zero adjusted Gamma distribution for the accumulated monthly precipitation. The adjustment revealed a spatial dependence of up to 873 km between the pluviometric stations and temporal autocorrelation of approximately 1.6 months. The methodology used in this study enabled us to create rainfall maps, interpolating unobserved locations in differences years. The projection of these maps to the SFRB is considered extremely important for planning and implementing activities related to water resources across the river basin.

Chia gel is known for its functional properties such as high water and oil retention capacity, emulsifying activity, and as a stabilizer for foams and emulsions. Thus, the objective of this study was to evaluate the effect of the inclusion of chia gel as a substitute for pork fat in formulations of fishburgers made with Nile tilapia. Five formulations, one control and four with increasing levels of substitution of chia gel (12.50, 25.00, 37.50 and 50.00%) were evaluated. The fishburgers were characterized regarding their physicochemical composition, their technological characteristics, and microbiological viability. With the incorporation of the gel, there was a significant reduction in lipid component and the caloric value of the formulations, in addition to an increase in the percentage of dietary fibre. In addition, no negative effects were observed regarding yield and the main texture parameters studied. However, the formulations with the highest percentage replacement of pork fat by chia gel were darker when compared to the control treatment. Chia gel may be considered as a novel substitute for pork fat; however, it is recommended that techniques be employed to produce lighter gels, thus avoiding possible rejection by the consumer.

RESUMO Tanto o papel social quanto o econômico da caprinocultura na região Nordeste do Brasil, somados ao fato de que o uso de ossículos da orelha média de caprinos para estudos e treinamento cirúrgico otológico humano ainda não foi proposto, justificam o estudo de sua aplicabilidade como modelo experimental. Foram dissecadas as orelhas médias de 19 caprinos (Capra aegagrus hircus), provenientes do ossuário do Laboratório e Museu Didático de Anatomia dos Animais Domésticos e Silvestres - Universidade Federal do Vale do São Francisco. Martelos, bigornas e estribos tiveram a morfologia macroscópica e a biometria (comprimento, largura e altura) avaliadas. A morfologia dos ossículos assemelhou-se a de ovinos, humanos e bovinos. O martelo foi 1,3 vez mais pesado e 2,2 vezes mais comprido que a bigorna e 9,0 vezes mais pesado e 3,7 vezes mais comprido que o estribo. A relação de tamanho entre o estribo e o martelo foi positiva, e entre o estribo e a bigorna negativa. Conclui-se que o tamanho da orelha média e as semelhanças anatômicas com os ossículos humanos tornam os caprinos um modelo útil para estudos científicos experimentais, prática cirúrgica reconstrutiva da cadeia ossicular e treinamento cirúrgico otológico humano.

ABSTRACT The social and economic roles of goat farming in Northeastern Brazil, allied to the fact that the use of goat middle ear ossicles for research and human ear surgery training has not yet been proposed, justify the study of their applicability as an experimental model. The middle ears of 19 goats (Capra aegagrus hircus) from the bone collection of the Laboratory and Didactic Anatomy Museum of Domestic and Wild Animals of the Federal University of Vale do São Francisco (UNIVASF) were dissected. The malleus, incus, and stapes were evaluated regarding their macroscopic morphology and biometry (length, width, and height). Ossicle morphology was similar to sheep, human, and bovine morphology. The malleus was 1.3 times heavier and 2.2 times longer than the incus, and 9.0 times heavier and 3.7 times longer than the stapes. The size relationship was positive between the stapes and the malleus and negative between the stapes and the incus. It is concluded that the middle ear size and the anatomical similarities with human ossicles make goats a useful model for experimental scientific studies, reconstructive surgery practice of the ossicular chain, and human ear surgery training.

The main movements of artistic swimming demand various physical capacities such as flexibility, strength, power, and muscular endurance. The use of ergogenic resources to potentialize performance in this sport, however, is underexplored and deserves investigation. In the present study, we tested whether caffeine ingestion would improve the execution of movements that are essential in a typical figure competition or routines in artistic swimming (i.e., amplitude in the Ariana, height in the Boost and Barracuda, and time maintained in the Stationary Scull techniques). Sixteen experienced female athlete artistic swimmers (17.4±3.2 years of age, 5.6±2.8 years of artistic swimming practice) performed several movements of artistic swimming after having ingested a capsule containing caffeine (5 mg/kg body mass) or cellulose (placebo). Compared to the placebo, caffeine improved latero-lateral amplitude during the Ariana (P=0.035), the height of the Boost and Barracuda (P=0.028 and 0.009), and maintained duration in Stationary Sculling (P=0.012). Bayes factor analysis, however, indicated substantial evidence of a positive effect of caffeine only on the Barracuda and Stationary Scull techniques. These findings indicated that caffeine improved performance during specific artistic swimming movements. Coaches and athletes should consider caffeine ingestion in their supplementation plans.

RESUMO Racional: A incidência de hérnia abdominal em pacientes cirróticos é elevada, em torno de 20%. Em casos de ascite volumosa, a incidência atinge valores até 40%. Uma das principais e mais graves complicações no pós-operatório de correção de hérnias de pacientes cirróticos é a insuficiência renal aguda (IRA). Objetivo: Analisar a função renal de pacientes cirróticos submetidos a herniorrafias, comparando aqueles que apresentavam IRA pós-operatório com os demais, para determinar os fatores relacionados à sua ocorrência. Método: Seguimento de pacientes cirróticos submetidos à cirurgia de hérnia entre 2001 e 2014 no Serviço de Transplante de Fígado. Foram coletados exames laboratoriais para avaliar a função renal no pós-operatório rotineiramente. A IRA foi definida com base no consenso do clube da ascite em 2015. Resultados: Dos 174 pacientes incluídos, ocorreu IRA em 58 pacientes (34,9%). Houve diferença entre grupos para as seguintes variáveis: MELD inicial, creatinina basal e creatinina, o grupo com IRA apresentou medias superiores ao grupo que não apresentou IRA. No grupo IRA PO, 74,1% das cirurgias, foram realizadas em caráter de emergência, enquanto que no grupo sem IRA no pós-operatório, 34,6%. No grupo IRA, 90,4% dos indivíduos apresentaram complicações no pós-operatório, enquanto no grupo sem IRA, 29,9%. As variáveis idade, MELD inicial, creatinina basal e creatinina no pós-operatório inicial foram estatisticamente significantes na análise de sobrevida. Conclusões: Existe uma associação entre IRA pós-operatória e cirurgia de emergência e IRA pós-operatóri e complicações pós-operatórias. Os fatores relacionados à maior ocorrência de IRA em pacientes cirróticos submetidos à cirurgia de hérnia são o MELD inicial, creatinina basal, creatinina pós-operatória inicial. O preparo de pacientes cirróticos com hérnia abdominal antes de procedimentos cirúrgicos deve ocorrer sistematicamente, pois apresentam alta incidência de IRA pós-operatória.

ABSTRACT Background: The incidence of abdominal hernia in cirrhotic patients is as higher as 20%; in cases of major ascites the incidence may increase up to 40%. One of the main and most serious complications in cirrhotic postoperative period (PO) is acute kidney injury (AKI). Aim: To analyze the renal function of cirrhotic patients undergoing to hernia surgery and evaluate the factors related to AKI. Methods: Follow-up of 174 cirrhotic patients who underwent hernia surgery. Laboratory tests including the renal function were collected in the PO.AKI was defined based on the consensus of the ascite´s club. They were divided into two groups: with (AKI PO) and without AKI . Results: All 174 patients were enrolled and AKI occurred in 58 (34.9%). In the AKI PO group, 74.1% had emergency surgery, whereas in the group without AKI PO it was only 34.6%.In the group with AKI PO, 90.4% presented complications, whereas in the group without AKI PO they occurred only in 29.9%. Variables age, baseline MELD, baseline creatinine, creatinine in immediate postoperative (POI), AKI and the presence of ascites were statistically significant for survival. Conclusions: There is association between AKI PO and emergency surgery and, also, between AKI PO and complications after surgery. The factors related to higher occurrence were initial MELD, basal Cr, Cr POI. The patients with postoperative AKI had a higher rate of complications and higher mortality.

ABSTRACT The aim of the present study was to evaluate the antibacterial behavior of polypyrrole nanoparticles (PPy-NPs) in water against biofilm producer or not S. aureus isolated from cows and goats with mastitis. One hundred and thirty-eight isolates of S. aureus were initially evaluated for biofilm formation by spectrophotometry in microplates. In addition, the minimum inhibition concentration (MIC) and minimum bactericidal concentration (MBC) of PPy-NPs in water for planktonic S. aureus were determined. From the bovine samples analyzed, 5 (4.46%) S. aureus isolates showed a strong biofilm production, 17 (15.18%) moderate production, 36 (32.14%) with weak production and 54 (48.21%) did not produce biofilms. Strains from goats (26) showed no biofilm production in 18 (69.23%) strains and weak biofilm production in 8 (30.76%) strains. The MIC and MBC of S. aureus to PPy-NPs were found in the same concentration (125µɡ/mL) in all strains tested, regardless of biofilm production or not. This finding provides a new insight into the interaction between PPy-NPs and S. aureus, and will offer potential benefits for the control of mastitis.

RESUMO Este trabalho investigou a influência da adiposidade em éguas Crioulas gestantes sobre o peso e o acúmulo de gordura de seus potros do nascimento aos quatro meses de vida. Foram avaliadas 28 éguas Crioulas no terço final de gestação, divididas em dois grupos (normais e obesas) quanto ao peso, à circunferência de pescoço, à altura da crista do pescoço e à gordura subcutânea na base da cauda, bem como quanto à relação dessas medidas com as de seus potros, do parto aos 120 dias de idade. Os filhos de éguas obesas apresentaram maior deposição de gordura na base da cauda, no segundo mês (P<0,05), e na crista do pescoço (P=0,0022), no quarto mês de idade. Houve correlação positiva da altura da crista do pescoço da égua com o peso dos potros ao nascer (P=0,01; r= 0,54) e do peso corporal das éguas com gordura na base da cauda dos potros ao nascimento (P=0,03; r=0,49), além de forte associação entre gordura na base da cauda das éguas obesas com essa medida nos seus potros aos quatro meses (P=0,01; r=0,71). Essa diferença entre os grupos de potros quanto à adiposidade sugere que filhos de éguas obesas são mais propensos a acumular mais gordura já nos primeiros meses de vida.

ABSTRACT This work investigated the influence of adiposity on pregnant Crioulo mares on the weight and fat deposition of their foals from birth to four months of life. Twenty-eight Crioulo mares were evaluated during the final third of gestation, divided into two groups (normal and obese) regarding weight, neck circumference, neck crest height and fat at the tail base, and the relation of these measurements with those of their foals from birth to 120 days old. The obese mares presented higher fat deposition at the tail base in the 2nd month (P< 0.05) and crest of the neck (P= 0.0022) in the 4th month of age. There was positive correlation between height of mare's neck crest and foal weight at birth (P= 0.01, r= 0.54) and body weight of mares between the fat at tail base of foals at birth (P= 0.03, r= 0.49), as well as strong association between fat at the tail base in obese mares with this measurement in their foals at 4 months (P= 0.01, r= 0.71). This difference of adiposity between groups suggests that obese mare’s offspring are more likely to accumulate more fat in the first months of life.

Resumo Dados de experimentos de campo conduzidos em parreirais de uva de mesa da variedade Festival, em Petrolina-PE, no período de outubro/2009 a novembro/2010, foram usados para avaliar a influência da cobertura plástica sobre o microclima, produtividade e impacto econômico de parreirais. Foram estudados três tratamentos: sem cobertura (SC); com cobertura plástica posicionada a 50 cm acima do dossel (CP50); e com cobertura plástica posicionada a 100 cm acima do dossel (CP100). Os resultados indicaram que a maior oferta de fluxos radiativos na altura das bagas no tratamento CP100 contribuiu para uma maior produtividade, enquanto que o tratamento CP50 teve a menor oferta de fluxos radiativos na altura das bagas e uma produtividade bem menor. A produtividade obtida no tratamento CP100 superou em 11 t ha-1 àquela do tratamento SC e em 12,3 t ha-1 a do tratamento CP50. O tratamento CP100, também foi o que apresentou as menores quantidades de defeitos graves e leves, o que contribuiu para uma maior receita total. Em contra partida, o tratamento CP50 teve uma produtividade acentuadamente menor, o que representou prejuízos econômicos consideráveis.

Abstract Data from field experiments conducted in vineyards table grape variety of Festival in Petrolina-PE, from October/2009 to November/2010, were used to evaluate the influence of the plastic cover on productivity and economic profitability of the viticulture in the São Francisco River Valley. Three treatments were studied: uncovered canopy (UC), plastic cover placed at 50 cm above the canopy (PC50), and a plastic cover placed at 100 cm above the canopy (PC100). The results indicated that the increased supply of radiative fluxes at the height of the berries in the treatment PC100 contributed to higher productivity, while treatment PC50 had the lowest offer of irradiative fluxes at the height of berries and much lower productivity. The yield obtained in the treatment PC100 exceeded 11 t ha-1 and 12.3 t ha-1 to those of treatments at UC and PC50, respectively. Treatment PC100 also had the lowest amounts of defects of berries, which contributed to higher total revenue. By contrast, treatment PC50 had markedly lower productivity, which represented considerable economic losses.

The neurochemical mechanisms underlying neuropathic pain (NP) are related to peripheral and central sensitization caused by the release of inflammatory mediators in the peripheral damaged tissue and ectopic discharges from the injured nerve, leading to a hyperexcitable state of spinal dorsal horn neurons. The aim of this work was to clarify the role played by cyclooxygenase (COX) in the lesioned peripheral nerve in the development and maintenance of NP by evaluating at which moment the non-steroidal anti-inflammatory drug indomethacin, a non-selective COX inhibitor, attenuated mechanical allodynia after placing one loose ligature around the nervus ischiadicus, an adaptation of Bennett and Xie's model in rodents. NP was induced in male Wistar rats by subjecting them to chronic constriction injury (CCI) of the nervus ischiadicus, placing one loose ligature around the peripheral nerve, and a sham surgery (without CCI) was used as control. Indomethacin (2 mg/kg) or vehicle was intraperitoneally and acutely administered in each group of rats and at different time windows (1, 2, 4, 7, 14, 21, and 28 days) after the CCI or sham surgical procedures, followed by von Frey's test for 30 min. The data showed that indomethacin decreased the mechanical allodynia threshold of rats on the first, second, and fourth days after CCI (P<0.05). These findings suggested that inflammatory mechanisms are involved in the induction of NP and that COX-1 and COX-2 are involved in the induction but not in the maintenance of NP.

Resumo: Objetivou-se adequar a metodologia do teste de vigor de plântulas normais intactas (fortes) de Amburana cearensis e avaliar a eficiência na classificação fisiológica de lotes de sementes desta espécie. O estudo foi conduzido em duas etapas: caracterização morfológica de plântulas e análise fisiológica dos lotes de sementes. Para isso, realizaram-se os testes de vigor de plântulas normais fortes, germinação, emergência, primeira contagem, índice de velocidade de germinação, tetrazólio, comprimento de plântulas normais fortes, comprimento e massa seca de plântulas. O delineamento experimental utilizado foi o inteiramente casualizado. Para comparação dos resultados foram realizados os testes de Tukey e Kruskal-Wallis, sendo a correlação entre as variáveis analisadas pelos coeficientes de Spearman e Pearson. As plântulas de A. cearensis são do tipo semi-hipógea fanerocotiledonar, com presença de plântulas normais ao nono dia após a semeadura. O teste de vigor de plântulas normais fortes, comprimento de plântulas normais fortes, massa seca e tetrazólio proporcionaram classificação fisiológica em diferentes níveis de vigor. O teste de vigor de plântulas normais fortes, o comprimento de plântulas normais fortes e o teste de tetrazólio (vigor) são eficientes para a classificação do vigor de sementes de A. cearensis.

Abstract: The aim of this study was to adapt the vigor test methodology of (strong) normal intact seedlings of Amburana cearensis and evaluate efficiency in physiological classification of seed lots. The study was conducted in two stages: morphological characterization of seedlings and physiological analysis of seed lots. To do so, the following tests were carried out: (strong) normal seedlings, germination, emergence, first count, germination speed index, tetrazolium, length of strong normal seedlings, length and dry mass of seedlings. The experimental design was completely randomized. The Tukey and Kruskal-Wallis tests were used to compare the results, and the correlation between the variables was analyzed by Spearman and Pearson coefficients. The seedlings of A. cearensis are semi-hypogeal phanerocotylar, with development of normal seedlings on the ninth day after sowing. The vigor test of strong normal seedlings, length of strong normal seedlings, dry matter, and tetrazolium led to physiological classification into different vigor levels. The vigor test of (strong) normal seedlings, the length of strong normal seedlings, and tetrazolium (vigor) were effective for vigor classification of A. cearensis seeds.
