Resumo A pandemia de Covid-19 impôs uma mudança radical nas práticas quotidianas. Algumas dessas novas práticas destacaram-se, por reduzirem o impacto ambiental da atividade humana, e muitos teóricos viram-nas como uma oportunidade para a construção de “novas normalidades”, mais justas e sustentáveis. Percebeu-se a capacidade das sociedades contemporâneas de realizarem mudanças radicais nas práticas, quando os esforços e recursos são orquestrados nessa direção. No entanto, após três anos desde o início da pandemia vemos um gradual retorno à normalidade. Este artigo indica como as teorias das práticas sociais nos podem ajudar a entender a estabilidade das práticas sociais em trajetórias insustentáveis e as possibilidades de transformação na direção da sustentabilidade.

Abstract The Covid-19 pandemic imposed a radical change in daily practices. Some of these new practices attracted attention for reducing the environmental impact of human activity, and many theorists saw this as an opportunity to build “new normalities” that are more just and sustainable. Contemporary societies have the capacity to make radical changes in practices, when the efforts and resources are orchestrated in that direction. However, three years after the start of the pandemic we see a gradual return to normality. This article indicates how social practice theories can help us understand the stability of social practices on unsustainable trajectories and their possibilities for transformation towards sustainability.

ABSTRACT Nitrogen (N) fertilization effectiveness in onion depends on N source, as well as on soil type and management system. The aim of the study is to investigate the effect of N sources and doses applied as top-dressing on bulb yield, leaf N contents and on the postharvest conservation of onion bulbs grown under no-tillage (NTS) and conventional tillage (CTS) systems. Three experiments were carried out: two in Lebon Régis County-SC, under NTS; and one in Caçador County-SC, under CTS. The herein tested N sources comprised urea, ammonium nitrate, calcium nitrate and ammonium sulfate, in combination to N doses applied as top-dressing (70, 140, 210, 280 and 350 kg N ha-1) in addition to the control, without N. The N sources did not affect yield parameters, leaf N content and post-harvest onion losses. The maximum technical efficiency in bulb yield was observed at N doses of 195.8 and 258.4 kg ha-1 in the no-tillage system (NTS) and at 270.7 kg N ha-1 in the CTS. The NTS enabled maximum yield at N dose 47% lower than the officially recommended one. Maximum relative commercial yield was associated with 31.1 g kg-1 of leaf N.

RESUMO Objetivo: Avaliar a dor e a mobilidade em pacientes com fraturas transtrocantéricas submetidos à osteossíntese com bloqueio do grupo de nervos pericapsulares (PENG) e comparar a pacientes que não receberam o bloqueio. Métodos: Foram analisados os prontuários de 49 pacientes e coletados dados referentes a: idade, sexo, avaliação anestésica, causa do trauma, locomoção, classificação da fratura, tipo de anestesia utilizada, técnica anestésica, dor, administração de opioide e deambulação com carga parcial. Resultados: Dos 49 pacientes, 17 (34,7%) receberam o bloqueio PENG. Após a cirurgia, a maioria dos pacientes queixou-se de dor e foi administrado opioide (67,3%), sendo a maior frequência no grupo sem o bloqueio PENG (93,3%). A maioria dos pacientes que receberam bloqueio PENG deambularam em até 6h após a cirurgia (52,9%) e todos recuperaram a capacidade de deambular até a alta hospitalar (48h), diferindo do grupo que não recebeu o bloqueio PENG (p = 0,012). Houve diferença significativa entre os grupos em relação à frequência de relatos de dor moderada a forte (p = 0,003). Conclusão: O uso de bloqueio PENG em pacientes com fraturas transtrocantéricas submetidos à osteossíntese pode auxiliar na diminuição da dor pós-operatória, deambulação precoce com carga parcial e menor necessidade de uso de opioides. Nível de Evidência III, Estudo Retrospectivo Comparativo.

ABSTRACT Objective: To evaluate pain and mobility in patients with transtrochanteric fractures subjected to osteosynthesis with pericapsular nerve group (PENG) block and compare with patients who did not receive the block. Methods: The medical records of 49 patients were analyzed and data were collected regarding: age, gender, anesthetic evaluation, cause of trauma, locomotion, fracture classification, type of anesthesia used, anesthetic technique, pain, opioid administration and mobility with partial load. Results: Out of 49 patients, 17 (34.7 %) received PENG block. After surgery, most patients complained of pain and opioids were administered (67.3 %), with greatest frequency in the group without PENG block (93.3 %). Most patients who received PENG block walked within 6 h after surgery (52.9 %) and all recovered the ability to walk until hospital discharge (48 h), different from the group that did not receive PENG block (p = 0.012). The groups showed a significant difference between them regarding the frequency of reports of moderate to severe pain (p = 0.003). Conclusion: The use of PENG block in patients with transtrochanteric fractures subjected to osteosynthesis can help to reduce postoperative pain, early mobility with partial load and less use of opioids. Level of Evidence III, Retrospective Comparative Study.

BACKGROUND Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was confirmed in Brazil in February 2020, the first cases were followed by an increase in the number of cases throughout the country, resulting in an important public health crisis that requires fast and coordinated responses. OBJECTIVES The objective of this work is to describe the isolation and propagation properties of SARS-CoV-2 isolates from the first confirmed cases of coronavirus disease 2019 (COVID-19) in Brazil. METHODS After diagnosis in patients that returned from Italy to the São Paulo city in late February by RT-PCR, SARS-CoV-2 isolates were obtained in cell cultures and characterised by full genome sequencing, electron microscopy and in vitro replication properties. FINDINGS The virus isolate was recovered from nasopharyngeal specimen, propagated in Vero cells (E6, CCL-81 and hSLAM), with clear cytopathic effects, and characterised by full genome sequencing, electron microscopy and in vitro replication properties. Virus stocks - viable (titre 2.11 × 106 TCID50/mL, titre 1.5 × 106 PFUs/mL) and inactivated from isolate SARS.CoV2/SP02.2020.HIAE.Br were prepared and set available to the public health authorities and the scientific community in Brazil and abroad. MAIN CONCLUSION We believe that the protocols for virus growth and studies here described and the distribution initiative may constitute a viable model for other developing countries, not only to help a rapid effective pandemic response, but also to facilitate and support basic scientific research.

RESUMO Introdução A exposição de trabalhos científicos é uma das metodologias utilizadas nos congressos e faz parte da comunicação informal do conhecimento científico, usada entre os cientistas ao se inserirem em um cotidiano restrito de pesquisadores. A tecnologia QR code facilita o acesso à produção científica e à dinamização do conhecimento; o Pôster Quiz constitui uma ferramenta de exploração dos trabalhos científicos facilitada pela inserção do QR code. Objetivos Relatar a criação e elaboração do Pôster Quiz como estratégia inovadora na exposição de trabalhos em um congresso de educação médica, aliada a uma ferramenta digital, o QR code, a fim de incentivar a leitura dos trabalhos expostos nos totens digitais, disseminando a pesquisa científica, seus autores e sua importância. Relato de experiência Trata-se de uma metodologia desenvolvida por discentes e docentes do curso de Medicina do Centro Universitário de Anápolis (UniEVANGÉLICA), em contou com reuniões periódicas que propunham a elaboração de QR codes que expusessem perguntas sobre resumos previamente lidos pelos participantes em formato e-poster. Esse processo envolveu a participação de sete discentes, um docente e 47 congressistas. Utilizaram-se banners com QR codes correspondentes às perguntas de seis totens de e-poster espalhados pelo evento, cartões-resposta referentes às perguntas expostas pelos QR codes e uma urna para depósito dos cartões; a correção dos cartões foi automática. Ao encontrarem um banner, os congressistas utilizavam um aplicativo leitor de QR code para obter acesso às questões daquele totem no período específico e em seguida tinham que realizar uma leitura dos trabalhos expostos ou assistir à apresentação do e-poster para que pudessem responder às questões. A correção dos cartões-resposta ocorreu por meio do aplicativo mobile Merrit®, que utiliza a câmera do smartphone para identificar as respostas de questões objetivas, comparando-as com um gabarito previamente informado. Do total de 150 questões, os primeiros colocados apresentaram 77 (51,33%), 76 (50,66%) e 70 (46,66%) acertos, sendo que a média de acertos foi de 61 (40,66%). Ao término do evento, ocorreu a premiação dos ganhadores nas três primeiras colocações. Também foram coletados relatos pessoais dos congressistas, atribuindo credibilidade a essa prática. Conclusão A importância dessa dinâmica repousa, sobretudo, na valorização dos trabalhos expostos com o objetivo de estimular o interesse dos congressistas, além de incentivar a integração entre os participantes da dinâmica e despertar maior atenção para as informações prestadas. Vale ressaltar o impacto positivo de uma atividade distinta de todas as outras do congresso, que agregou um elemento competitivo favorável ao objetivo primordial de obter conhecimento. O uso dessa nova tecnologia teve um resultado auspicioso, visto que a criação de um desafio premiado promoveu benefícios intelectuais, como a aquisição de habilidades de leitura e o aprendizado de temas pouco retratados na faculdade. A eficácia dessa dinâmica reside numa troca proveitosa de conhecimentos e de interesse entre os participantes, os autores dos trabalhos e os elaboradores do Pôster Quiz.

ABSTRACT Introduction Scientific works are routinely presented at medical congresses, contributing to the informal communication of scientific knowledge among scientists in a context of a restricted number of researchers. QR codes facilitate access to scientific production and promote more dynamic learning, and the Poster-Quiz is a tool we used to explore such works by means of QR codes. Objectives To report on the creation and development of a Poster-Quiz as an innovative form of displaying works at a medical congress, with a view to encouraging reading of the works exhibited in the digital totems, disseminating and highlighting the importance of scientific research and its authors. Experience report A methodolody developed by students and professors of the Medicine course at UniEVANGÉLICA – University Centre of Anápolis, involving periodic meetings to propose the use of QR codes to set questions about previously read abstracts displayed in e-posters. This process included the participation of seven students, one professor and 47 congress participants. The experiment was conducted with the use of banners with QR codes corresponding to questions about the content of six digital totems spread around the event, response cards and an urn for collection of the cards, which were corrected automatically. Upon finding a banner, the congress participants used a QR code reader app to access the questions relative to that totem in the specific period and then had to read the works presented or watch a presentation of the e-poster in order to answer the questions. The mobile app Merrit®, using a smartphone camera was employed to identify the answers to the objective questions, comparing them to a previously established answer sheet. There were 150 quiz questions in all and the top-performing respondents achieved scores of 51.33%, 50.66% and 46.66% correct answers. The average score was around 40.66% correct answers. At the end of the event, the top three respondents were awarded. The participants were also asked to give their opinion on the quiz experience in order to lend credibility to the practice. Conclusion The importance of this activity resides, above all, in promoting the works exposed in order to spark the interest of the congress participants, as well as encouraging greater integration between the participants and provoking them to pay closer attention to the information exhibited. We should highlight the positive impact of an activity which is clearly different to the others found at the congress, and which added a competitive element that enhanced the main objective of learning. The use of this new technology had an auspicious outcome, seeing as the creation of a competitive challenge promoted intellectual benefits, such as the aquisition of reading abilities and learning about matters that are given little attention at university. The effectiveness of the quiz derives from a mutually beneficial exchange of knowledge and interest among the participants, authors of the works and the organizers of the Poster-Quiz.

ABSTRACT Introduction: Aging causes an increase in cardiovascular morbidity that can be reflected in the electrocardiogram, but not all older adults' subpopulations have been systematically studied. Objectives: To determine the main electrocardiographic alterations that occur in elderly patients with cardiovascular morbidities. Method: Cross-sectional descriptive study in 148 patients ≥ 60 years, with cardiovascular morbidities, admitted to the Internal Medicine service of the "Hospital Celestino Hernández Robau" in Villa Clara. Electrocardiographic variables suggestive of cardiac involvement were identified. Results: The average age was 77.4 ± 8.2 years. Atrial fibrillation was seen in 16.9% of cases. There were alterations of ventricular repolarization in 39.3% of cases, as well as left/right bundle branch block in 14.4% and 5.4% respectively. A 24.7% of patients presented left atrial abnormality and 17.8% QT prolongation. The highest number of cases with electric left ventricular hypertrophy was detected with the R aVL criteria (9 patients [10.2%]). Conclusions: The most frequent rhythm disorder was atrial fibrillation. Alterations of ventricular repolarization prevailed over those of depolarization with no association with sex or skin color. There was a considerable number of cases with left atrial abnormality, left ventricular hypertrophy and long QT.

RESUMEN Introducción: Como parte del envejecimiento ocurre un incremento de la morbilidad cardiovascular que puede reflejarse en el electrocardiograma, pero no todas las subpoblaciones de adultos mayores han sido estudiadas sistemáticamente. Objetivos: Determinar las principales alteraciones electrocardiográficas que acontecen en pacientes adultos mayores con morbilidades cardiovasculares. Método: Estudio descriptivo, transversal en 148 pacientes ≥ 60 años, con morbilidades cardiovasculares, ingresados en el servicio de Medicina Interna del Hospital Celestino Hernández Robau de Villa Clara. Se determinaron variables electrocardiográficas sugerentes de afectación cardíaca. Resultados: La edad promedio fue 77,4 ± 8,2 años. La fibrilación auricular fue observada en 16,9% de los casos. Existieron alteraciones de la repolarización ventricular en 39,3% de los casos, así como bloqueo de rama izquierda o derecha en 14,4% y 5,4%, respectivamente. Un 24,7% de los pacientes presentaron anormalidad auricular izquierda y 17,8%, prolongación del QT. El mayor número de casos con hipertrofia ventricular izquierda eléctrica se detectó con el criterio R aVL (9 pacientes [10,2%]). Conclusiones: El trastorno del ritmo más frecuente fue la fibrilación auricular. Las alteraciones de la repolarización ventricular prevalecieron sobre las de la despolarización, sin asociación con el sexo o color de piel. El número de casos con anormalidad auricular izquierda, hipertrofia ventricular izquierda y QT largo fue considerable.

Resumo Introdução O monitoramento a longo-prazo de reabilitações implantossupportadas é extremamente importante para avaliação dos parâmetros que podem interferir no sucesso do tratamento. Objetivo Avaliar a influência do macrodesenho (forma do corpo e ápice), comprimento e diâmetro, torque de inserção, região de instalação, assim como o protocolo de carregamento, na sobrevivência a longo-prazo. Material e método Os dados foram obtidos a partir dos prontuários de pacientes reabilitados com pelo menos um implante cone Morse na Faculdade Ilapeo entre os anos de 2006 e 2012. Prontuários com preenchimento incompleto, que pudesse interferir na coleta de dados foram excluídos da amostra. Resultado Um total de 1142 prontuários compôs a amostra, resultando num total 5601 implantes, instalados tanto em mandíbula como em maxila. A taxa de sobrevivência final foi de 98,31%, em um tempo médio de 37,54 meses. O tipo de implante mais utilizado foi o cilíndrico (70,33%). O torque médio de instalação ficou entre 41 e 50 Ncm. Uma análise de regressão logística mostrou que nenhuma das seguintes variáveis, local de instalação, forma do corpo e ápice e comprimento, teve influência estatisticamente significante na perda de implantes. O aumento do torque e o diâmetro influenciaram a perda do implante e a carga imediata favoreceu a estabilidade. Conclusão Pode ser concluído que implantes cone Morse apresentam índice de sobrevivência elevado que pode ser influenciado por um torque excessivo assim como pelo diâmetro do implante.

Abstract Introduction The long-term implant-supported prosthetic rehabilitation monitoring is extremely important in evaluating parameters that could interfere in the success of the treatment. Objective To evaluate the influence of macrodesign (shape of the body and apex), length and diameter, insertion torque, site of installation as well as the loading protocol, on long-term survival rates. Material and method The data obtained was from the medical records of rehabilitated patients who had had at least one Morse taper implant surgery done at ILAPEO School between 2006 -2012. Incomplete medical records, from which it would have been impossible to extract all data essential to complete the study, were excluded. Result A total of 1,142 patient’s medical records comprised the sample; documenting the progress of 5,601 implants, done in both jaws and mandibles. The final survival rate was 98.31%, over an average time of 37.54 months. The type of implant most used was cylindrical (70.33%). The mean installation torque most evidenced in the study was between 41 and 50 Ncm. A logistical regression analysis showed that none of the following variables, site of installation, body and apex shape designs and length, had any significant statistical influence on implant loss. Torque increase and diameter influenced implant loss while immediate loading favored implant maintenance. Conclusion It can be concluded that Morse taper implants present a long-term survival rate that can be lowered by excessive torque, as well as by the diameter of the implant.

Resumen Rizobios son capaces de influir en el rendimiento de las especies no leguminosas través de la producción de sustancias fitoestimulantes. El objetivo de este estudio fue el de estudiar el efecto de la inoculación de rizobios UFRGS Lc348 y VP16 sobre la germinación y el rendimiento de millo y pasto Sudán, así como verificar si el enriquecimiento del medio de cultivo con triptófano interfiere en la interacción rizobio/planta. Para este fin se llevaron a cabo experimentos in vitro y bajo condiciones de invernadero. En el experimento con millo en condiciones in vitro, la inoculación con VP16 cultivado en medio enriquecido o no enriquecido con triptófano induce una mayor extensión de hipocótilo y epicótilo. El tratamiento UFRGS Lc348 induce una mayor extensión de hipocótilo en plantas de millo. En plantas adultas de millo no hubo efecto de la inoculación. En pasto Sudán, la inoculación de VP16 enriquecida con triptófano aumentó la masa seca de las plantas adultas. Los aumentos de elongación de plántulas de millo en condiciones in vitro pueden representar una ventaja adaptativa en la búsqueda de agua y nutrientes en el ambiente rizosférico durante el crecimiento inicial del millo. De manera similar, si se verifica en condiciones de campo, el incremento de pasto Sudán observado en condiciones de invernadero con la inoculación de VP16 enriquecido con triptófano, esto puede significar una ganancia significativa en el rendimiento del cultivo. Por lo tanto, estas relaciones entre VP16 enriquecido con triptófano y pasto Sudán deben ser verificadas en estudios posteriores en condiciones de campo.

Abstract Rhizobia are able to increase yield of non-leguminous species through production of phyto-stimulating substances. This study aimed to evaluate the inoculation effect of rhizobia UFRGS Lc348 and VP16 on millet and Sudan grass yield and germination, and verify the enrichment effect of culture medium with tryptophan, which leads on the rhizobium/plant interaction. Experiments in vitro and greenhouse conditions were conducted. In millet, the inoculation with VP16 grown in culture medium with or without tryptophan induces greater length of hypocotyl and epicotyl under in vitro conditions. UFRGS Lc348 treatment induces longer hypocotyls of millet under in vitro conditions. No effects were observed with the millet inoculation in greenhouse. In Sudan grass, inoculation with VP16 enriched with tryptophan increased dry matter in shoots of adult plants. In millet seedlings had achieved an increasing in elongation in vitro conditions, which could represent an adaptive advantage in the search for water and nutrients in the rhizospheric environment during the initial growth of millet. Similarly, if verified in field conditions, Sudan grass had achieved an increasing in greenhouse conditions with the inoculation of tryptophan-enriched VP16, which could be correlated with a significant gain in crop yield. Therefore, these relationships between tryptophan-enriched VP16 and Sudan grass should be verified in subsequent studies under field conditions.

RESUMO No estado do Rio Grande do Sul, os reflorestamentos de eucalipto encontram-se, geralmente, em solos de baixa fertilidade natural, favorecendo a associação ectomicorrízica. Neste trabalho, avaliou-se o efeito da inoculação dos isolados de fungos ectomicorrízicos UFSC-Pt116, UFSC-Pt188 e UFSC-SA9, sobre plantas de Eucalyptus grandis, em Neossolo Quartzarênico. As avaliações foram realizadas aos 30, 45, 60, 75 e 90 dias após semeadura. Plantas inoculadas com os isolados UFSC-Pt116, UFSC-Pt188 e UFSC-SA9 alcançaram maior altura, diâmetro do caule, massa seca da parte aérea e volume de raízes em relação ao controle. Plantas inoculadas com o isolado de fungo ectomicorrízico UFSC-Pt188 apresentaram maior teor de fósforo e potássio na parte aérea que as plantas não inoculadas. A inoculação com o isolado fúngico ectomicorrízico UFSC-Pt116 promoveu maior altura e massa seca da parte aérea. Para os teores de nitrogênio e potássio, e para massa seca de raízes não foram observadas diferenças significativas entre os tratamentos. A inoculação com os fungos ectomicorrízicos UFSC-Pt116, UFSC-SA9 e UFSC-Pt188 isoladamente, promoveram maior altura, diâmetro de caule, acúmulo de massa seca da parte aérea e volume de raízes das plantas de Eucalyptus grandis.

ABSTRACT In Rio Grande do Sul state, the eucalyptus planted forests are cultivated in low fertility soils, which contribute to ectomycorrhizal association. This study evaluated the effect of ectomycorrhizal isolates UFSC-Pt116, UFSC-Pt188 and UFSC-SA9 inoculation, individually and in combination, with Eucalyptus grandis in Quartzarenic Neosols. Evaluations were performed at 30, 45, 60, 75 and 90 days after sowing. Plants inoculated with isolates UFSC-Pt116, UFSC-Pt188 and UFSC-SA9 showed highest height, stem diameter, dry mass of shoot and root volume than the control. Plants inoculated with the ectomycorrhizal fungus isolate UFSC-Pt188 showed highest content of phosphorus and potassium in shoots than non-inoculated plants. Inoculation individual ectomycorrhizal isolate UFSC-Pt116 promoted the highest height and shoot dry mass. For nitrogen and potassium, and root biomass have not showed significant differences between treatments. Then inoculation with ectomycorrhizal UFSC-Pt116, UFSC-Pt188 and UFSC-SA9 alone promoted highest height, stem diameter, dry mass of shoot and plant root volume of Eucalyptus grandis.

ABSTRACT Rhizobia and associative bacteria promote growth in rice plants (Oryza sativa L.) through a series of mechanisms, but most studies on inoculation have been performed based on inoculation with these bacteria in a separate or singular manner. The objective of this study was to assess the efficiency of single/isolated inoculation and inoculation combined with symbiotic rhizobia from forage legume and with Azospirillum brasilense on promoting growth and the root colonization process in wetland rice. Two rhizobia among four isolates from a greenhouse and a laboratory experiment were selected that efficiently promoted seed germination and rice plant growth in a sterilized substrate and in soil. The two most efficient isolates (UFRGS Vp16 and UFRGS Lc348) were inoculated alone or in combination with a commercial product containing A. brasilense in two field experiments using two wetland rice cultivars over two growing seasons. In the field experiments, these isolates coinoculated with A. brasilense promoted larger increases in the agronomic variables of wetland rice compared to the control without inoculation. Confocal laser microscopy confirmed the presence of inoculated bacteria tagged with gfp (UFRGS Vp16, UFRGS Lc348, and A. brasilense) colonizing the root surface of the rice seedlings, mainly in the root hairs and lateral roots.

ResumoA presente pesquisa analisa o processo de formação de uma comunidade em torno de uma marca antes do seu efetivo lançamento no mercado. Para isso, utilizou-se o método netnográfico para investigar uma comunidade automotiva criada meses antes da chegada do automóvel às ruas. O trabalho sugere a busca por informações e o desejo de influenciar o desenho da nova oferta, como fatores a mobilizar os consumidores em torno da comunidade. O envolvimento com a categoria, o posicionamento aspiracional da marca corporativa e a expectativa de mudanças a partir desse lançamento também se mostraram como aspectos relevantes na constituição do grupo. O trabalho sugere uma tipologia de membros a partir de duas dimensões: a informação sobre a categoria e a experiência de uso com a marca/modelo em questão. A tipologia distingue novatos (baixa informação e baixa experiência), teóricos (alta informação e baixa experiência), pragmáticos (baixa informação e alta experiência) e experts (alta informação e alta experiência) e evidencia lógicas que hierarquizam as interações entre os membros, ajudando a explicar as dinâmicas e o processo de evolução da comunidade.

AbstractThis article presents an investigation of the building process of an online brand-associated community. It uses netnographic methods to investigate an automotive community, created months before a new model was actually launched. The study highlights the motivation to gather information and to influence product launch as factors to mobilize community existence. Category involvement, aspirational positioning of the corporate brand and revolutionary promises for this product also seem to be relevant to promote the community. The research presents a typology of community members based on two dimensions: information about the category and user experience with the brand/model. The typology distinguishes between newbies (low information and low experience), theoretical (high information and low experience), pragmatic (low information and high experience) and experts (high information and high experience). The paper highlights logics that stratify members´ interactions, explaining community formation dynamics and evolution processes.

Eucalypts is one of the main species used for commercial reforestation in the state of Rio Grande do Sul, Brazil. This study aimed to evaluate the survival and early growth of eucalyptus trees in an area subject to sandy process after three years of growth. The Eucalyptus grandis seedlings were grown in a greenhouse, innoculated or not with the isolated ectomycorrhizal Pisolithus microcarpus (UFSC-Pt116), produced in peat or Entisol. After 120 days, the seedlings were transplanted to an area subject to the sandy process, in the city of São Francisco de Assis, RS. The plants have been evaluated regarding survival, height, stem diameter, nitrogen, phosphorus and potassium levels and total phosphorus, inorganic phosphorus, organic phosphorus and wood production on different days after planting. The seedlings grown on the Entisol which was inoculated with the isolated UFSC-Pt116 presented higher survival rates, height, stem diameter, nitrogen concentration and wood production compared to the non-inoculated seedlings. Inoculation with ectomycorrhizal fungi enhanced the production of E. grandis seedlings in survival rates, height, stem diameter.
