ABSTRACT Fresh corn is a highly appreciated vegetable in Brazil; this crop has high added value and profitability when compared to dry corn. Despite the consumer market demand for quality, cultivars are not launched every crop season and there is a small number of cultivars available to growers. This denotes a need for breeding programs focused on generating information and genotypes that can occupy this market niche. The objective of this work was to evaluate the progress of five cycles of intrapopulation recurrent selection in half-sib progenies of fresh corn, in the southwest region of Goiás. A randomized block experimental design was used, with evaluation of 64 progenies of corn half-sib progenies and selection intensity of 30% per cycle, with three replications, in the 2011-2012, 2013-2014, 2015-2016, 2017-2018, and 2020-2021 summer crop seasons. The half-sib progenies of fresh corn exhibited genetic variability through intrapopulation recurrent selection in the different selection cycles, which is still promising for further selections after five cycles, with evaluation of 64 progenies per cycle. The base population from crossings between hybrids for tropical and temperate climates showed to be promising for increasing the genetic base of fresh corn populations, with satisfactory gains over the five cycles, presenting mean heritability between the cycles of approximately 78.9% for relative chlorophyll index, 62.2% for plant height, 75.1% for ear insertion height, 70% for ear diameter, 56.6% for ear length, 71.4% for unhusked ear yield, and 71% for marketable ear yield.
RESUMO O milho fresco é uma hortaliça muito apreciada pelos brasileiros e, além disso, possui alto valor agregado e maior lucratividade, quando comparado aos grãos secos. O mercado consumidor apesar de exigente na qualidade, não é abastecido com novas cultivares a cada safra e com um número ínfimo sendo disponível aos produtores. Assim, existe a necessidade da criação de programas de melhoramento, com o intuito de gerar informações e genótipos capazes de suprir esse nicho de mercado. O objetivo do estudo foi avaliar o progresso da seleção em progênies de meiosirmãos de milho fresco, em cinco ciclos de seleção recorrente intrapopulacional, na região sudoeste de Goiás. O delineamento experimental utilizado foi o de blocos casualizados, com a avaliação de 64 progênies de meios-irmãos e intensidade de seleção de 30% por ciclo, com três repetições, em diferentes safras de verão (2011-2012, 2013-2014, 2015-2016, 2017-2018 e 2020-2021). As progênies de famílias de meios-irmãos de milho fresco apresentaram variabilidade genética por meio de seleção recorrente intrapopulacional nos diferentes ciclos de seleção, com avaliação de 64 progênies por ciclo. A população base de cruzamentos entre híbridos para climas tropicais e temperados mostrou-se promissora para aumentar a base genética de populações de milho fresco, com ganhos satisfatórios ao longo dos cinco ciclos, com herdabilidade média de aproximadamente 78,9% para o índice relativo de clorofila, 62,2% para altura de planta, 75% para inserção da espiga, 70% para diâmetro da espiga, 56,6% para comprimento da espiga, 71,4% para espigas empalhadas e 71% para espigas comerciais entre os ciclos.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

Abstract Triticale high moisture grain triticale silage is an excellent option for ruminant diets, but loss control during its fermentation process should be further investigated. Thus, the objective of this study was to evaluate the effects of chemical and biological additives on high moisture triticale silages under chemical-bromatological composition, aerobic stability, and in vivo digestibility and ingestive behavior in sheep. The treatments were: high moisture triticale silage without additive (HMTC); high moisture triticale silage with enzyme-bacterial inoculant (HMTEB); high moisture triticale silage with 0.5 % urea in natural matter (HMTU); and high moisture triticale silage with 1.5 % sodium benzoate in natural matter (HMTSB). Four sheep were housed in appropriate metabolic cages according to the ethical principles of animal experimentation. The addition of urea as additive to high moisture triticale silage provided an increase in crude protein and ammoniacal silage (189.7 and 106.2 g kg MS-1, respectively) but did not affect digestibility (699.6 g kg MS-1 for HMTU, with a general average of treatments of 687.5 g kg MS-1) and ingestive behavior of sheep. Fiber consumption by sheep increased with the addition of the enzyme-bacterial additive in the silage (431.87 versus 388.06 g d-1 of FDN for HMTEB and HMTC, respectively). All additives helped to preserve crude protein contents after silo opening, but none interfered in aerobic stability time of silage.
Resumen El ensilaje de triticale de grano con alto contenido de humedad es una excelente opción para las dietas de rumiantes. Sin embargo, falta información sobre el control de pérdidas durante el proceso de fermentación. Se hizo una evaluación sobre los efectos de los aditivos químicos y biológicos a ensilajes de triticale de alta humedad en la composición química-bromatológica, la estabilidad aeróbica, la digestibilidad in vivo y el comportamiento de ingesta en ovinos. Se evaluaron cuatro tratamientos: ensilaje de triticale sin aditivo (control); ensilaje con un inoculante enzimático-bacteriano; ensilaje con 0.5% de urea en materia natural; y ensilaje con benzoato de sodio al 1.5% en materia natural. El comportamiento de ingesta se evaluó con cuatro ovejas macho en jaulas metabólicas. La adición de urea como aditivo proporcionó un aumento en el contenido de la proteína cruda (189.7 g kg MS-1) y el nitrógeno amoniacal (106.2 g kg MS-1), pero no afectó la digestibilidad (699.6 g kg MS-1 en tratamiento con urea, promedio = 687.5 g kg MS-1) ni el comportamiento de ingesta. El consumo de fibra aumentó con la adición del aditivo enzimático-bacteriano (431.87 vs 388.06 g d-1 fibra detergente neutra en el control). Todos los aditivos ayudaron a preservar el contenido de proteína cruda después de la apertura del silo, pero ninguno interfirió en el tiempo de estabilidad aeróbica del ensilado.

RESUMEN El pasto amargo (Digitaria insularis) es una de las principales malezas en el cultivo de soya. Para controlar su crecimiento, se requiere un aumento de las tasas de herbicida para simplificar su manejo al ser una planta con alta capacidad vegetativa y producción de semillas. Esto implica seleccionar los biotipos de Digitaria insularis resistentes a herbicidas Sin embargo, aún existe cierta información contrastante que considera el antagonismo de los herbicidas auxínicos sintéticos en las mezclas con inhibidores de ACCase y glifosato, para el control de malezas resistentes o tolerantes a los herbicidas. El estudio tuvo como objetivo evaluar el control de D. insularis con mezclas de herbicidas aplicados en la pre-emergencia y pos-emergencia del cultivo de soya y se verificó el posible antagonismo entre los herbicidas inhibidores de ACCase con auxinas sintéticas y otros latifolicidas. El experimento se realizó en Palotina, Paraná, (Brasil) y Corpus Christi, Canindeyú (Paraguay). Los tratamientos consistieron en mezclas de glifosato, inhibidores de ACCase (cletodim, haloxifop) y latifolicidas (2,4-D, triclopir, dicamba, carfentrazona, saflufenacil, clorimurón). Se utilizó un diseño de bloques al azar. El control de arvenses fue satisfactorio sólo en Palotina después de la aplicación secuencial en pos-emergencia. Allí se observó un control efectivo de D. insularis en la pre-emergencia, para algunas mezclas que presentaron glifosato+ACCase+carfentrazona, saflufenacil o clorimurón. Se observó antagonismo para todas las auxinas sintéticas en ambas ubicaciones. En Corpus Christi las mezclas de herbicidas no fueron efectivas, incluso con la aplicación de glifosato+cletodim en la pos-emergencia de soya. Aunque se obtuvo un control ineficaz para tratamientos compuestos con auxinas sintéticas, la aplicación en post-emergencia de soya aumentó el nivel de control, con resultados finales satisfactorios para todos los tratamientos.
ABSTRACT Sourgrass (Digitaria insularis) is one of the main weeds in the soybean crop. In order to control its growth, an increase of herbicide rates is required to simplify its management as it a plant with high vegetative capacity and seed production. It implies to select the herbicide-resistent Digitaria insularis biotypes. Nevertheless, some information is still contrasting the antagonist of synthetic auxinic herbicides, associated with glyphosate and ACCase inhibitors mixtures, for the control of weeds resistant or tolerant to herbicides. This study aimed to evaluate the D. insularis control, with a mixture of herbicides applied in soybean pre-emergence, with sequential application in soybean post-emergence, and to check possible antagonism between ACCase inhibitors herbicides with synthetic auxins and other latifolicides. The experiment was conducted in Palotina, Paraná (Brazil) and Corpus Christi, Canindeyú, (Paraguay.) The treatments consisted of associations of glyphosate, ACCase inhibitors (clethodim, haloxyfop), and latifolicides (2,4-D, triclopyr, dicamba, carfentrazone, saflufenacil, chlorimuron). A randomized block design was used. Only in Palotina, the weed control was satisfactory after sequential application in post-emergence. An antagonism for all synthetic auxins was observed with glyphosate+clethodim or haloxyfop mixtures, in both locations. As a result, in Palotina an efficacious control of perennial D. insularis was found in pre-emergence burndown for some mixtures such as glyphosate+ACCase inhibitor added to carfentrazone, saflufenacil, or chlorimuron. Antagonism was observed for all synthetic auxins, in both locations. In Corpus Christi, the herbicide associations were not effective, even with the post-emergence application in soybean of glyphosate+clethodim. With ineffective control for treatments composed with synthetic auxins, the post-emergence application in soybean increased the weed control with satisfactory final controls for all treatments.

RESUMO Objetivo: Descrever as práticas de ressuscitação volêmica em unidades de terapia intensiva brasileiras e compará-las com as de outros países participantes do estudo Fluid-TRIPS. Métodos: Este foi um estudo observacional transversal, prospectivo e internacional, de uma amostra de conveniência de unidades de terapia intensiva de 27 países (inclusive o Brasil), com utilização da base de dados Fluid-TRIPS compilada em 2014. Descrevemos os padrões de ressuscitação volêmica utilizados no Brasil em comparação com os de outros países e identificamos os fatores associados com a escolha dos fluidos. Resultados: No dia do estudo, foram incluídos 3.214 pacientes do Brasil e 3.493 pacientes de outros países, dos quais, respectivamente, 16,1% e 26,8% (p < 0,001) receberam fluidos. A principal indicação para ressuscitação volêmica foi comprometimento da perfusão e/ou baixo débito cardíaco (Brasil 71,7% versus outros países 56,4%; p < 0,001). No Brasil, a percentagem de pacientes que receberam soluções cristaloides foi mais elevada (97,7% versus 76,8%; p < 0,001), e solução de cloreto de sódio a 0,9% foi o cristaloide mais comumente utilizado (62,5% versus 27,1%; p < 0,001). A análise multivariada sugeriu que os níveis de albumina se associaram com o uso tanto de cristaloides quanto de coloides, enquanto o tipo de prescritor dos fluidos se associou apenas com o uso de cristaloides. Conclusão: Nossos resultados sugerem que cristaloides são usados mais frequentemente do que coloides para ressuscitação no Brasil, e essa discrepância, em termos de frequências, é mais elevada do que em outros países. A solução de cloreto de sódio 0,9% foi o cristaloide mais frequentemente prescrito. Os níveis de albumina sérica e o tipo de prescritor de fluidos foram os fatores associados com a escolha de cristaloides ou coloides para a prescrição de fluidos.
Abstract Objective: To describe fluid resuscitation practices in Brazilian intensive care units and to compare them with those of other countries participating in the Fluid-TRIPS. Methods: This was a prospective, international, cross-sectional, observational study in a convenience sample of intensive care units in 27 countries (including Brazil) using the Fluid-TRIPS database compiled in 2014. We described the patterns of fluid resuscitation use in Brazil compared with those in other countries and identified the factors associated with fluid choice. Results: On the study day, 3,214 patients in Brazil and 3,493 patients in other countries were included, of whom 16.1% and 26.8% (p < 0.001) received fluids, respectively. The main indication for fluid resuscitation was impaired perfusion and/or low cardiac output (Brazil: 71.7% versus other countries: 56.4%, p < 0.001). In Brazil, the percentage of patients receiving crystalloid solutions was higher (97.7% versus 76.8%, p < 0.001), and 0.9% sodium chloride was the most commonly used crystalloid (62.5% versus 27.1%, p < 0.001). The multivariable analysis suggested that the albumin levels were associated with the use of both crystalloids and colloids, whereas the type of fluid prescriber was associated with crystalloid use only. Conclusion: Our results suggest that crystalloids are more frequently used than colloids for fluid resuscitation in Brazil, and this discrepancy in frequencies is higher than that in other countries. Sodium chloride (0.9%) was the crystalloid most commonly prescribed. Serum albumin levels and the type of fluid prescriber were the factors associated with the choice of crystalloids or colloids for fluid resuscitation.

Abstract The Program for Biodiversity Research (PPBio) is an innovative program designed to integrate all biodiversity research stakeholders. Operating since 2004, it has installed long-term ecological research sites throughout Brazil and its logic has been applied in some other southern-hemisphere countries. The program supports all aspects of research necessary to understand biodiversity and the processes that affect it. There are presently 161 sampling sites (see some of them at Supplementary Appendix), most of which use a standardized methodology that allows comparisons across biomes and through time. To date, there are about 1200 publications associated with PPBio that cover topics ranging from natural history to genetics and species distributions. Most of the field data and metadata are available through PPBio web sites or DataONE. Metadata is available for researchers that intend to explore the different faces of Brazilian biodiversity spatio-temporal variation, as well as for managers intending to improve conservation strategies. The Program also fostered, directly and indirectly, local technical capacity building, and supported the training of hundreds of undergraduate and graduate students. The main challenge is maintaining the long-term funding necessary to understand biodiversity patterns and processes under pressure from global environmental changes.

RESUMEN Las mezclas entre herbicidas, el uso de múltiples sitios de acción y otras prácticas de manejo de malezas son necesarias para evitar otros casos de resistencia de biotipos. El objetivo de este estudio fue evaluar la eficiencia de imazapic/imazapyr y otros herbicidas en mezclas para controlar Digitaria insularis en la desecación antes de la siembra de soya. Esta investigación de campo se realizó en Umuarama, Estado de Paraná (PR), Brasil, en la cosecha de soya de 2018/19. El experimento se realizó en un diseño experimental de bloques al azar, con cuatro repeticiones y 11 tratamientos, compuestos por la aplicación de glifosato, cletodim, haloxifop, imazapic/imazapir, glufosinato, ácido 2,4-diclorofenoxiacético (2,4-D), dicamba, triclopir y saflufenacil, en mezclas. Se evaluó el control de malezas, así como el daño y el rendimiento de la soya. Se realizaron un análisis de varianza y test F, y se compararon las medias de los tratamientos con el test de Scott-Knott. Todos los tratamientos mostraron un gran control sobre la maleza y una baja tasa de daño a los cultivos mientras se mantenía el rendimiento de la soya. La aplicación de imazapic/imazapir en mezclas con otros herbicidas fue eficaz en el control de D. insularis resistente al glifosato, en desecación antes de la siembra de soya y con aplicación secuencial de haloxifop + glifosato en la etapa V3 de la soya. Este manejo químico también fue selectivo para la soya.
ABSTRACT Herbicide mixtures, use of multiple sites of action, and other weed management practices are necessary to avoid cases of biotype resistance. The aim of this study was to evaluate the efficiency of imazapic/imazapyr and other herbicides in mixtures to control Digitaria insularis at burndown before soybean sowing. This field research was conducted in Umuarama, State of Parana (PR), Brazil, in the 2018/19 soybean season. The experiment was conducted in a randomized block experimental design with four replicates and 11 treatments composed of the application of glyphosate, clethodim, haloxyfop, imazapic/ imazapyr, glufosinate, 2,4-dichlorophenoxyacetic acid (2,4-D), dicamba, triclopyr, and saflufenacil, in mixtures. Weed control was evaluated as well as soybean injury and yield. An analysis of variance and F-test were performed, and the treatment means were compared by the Scott-Knott test. All treatments showed great control over the weed and low crop injury rate while maintaining soybean yield. The application of imazapic/ imazapyr in mixtures with other herbicides was effective in controlling glyphosate-resistant D. insularis in burndown before soybean sowing and with sequential application of haloxyfop + glyphosate at V3 stage of soybean. This chemical management was also selective for soybean.

Abstract Background: South American rattlesnakes are represented in Brazil by a single species, Crotalus durissus, which has public health importance due to the severity of its envenomation and to its wide geographical distribution. The species is subdivided into several subspecies, but the current classification is controversial. In Brazil, the venoms of C. d. terrificus and C. d. collilineatus are used for hyperimmunization of horses for antivenom production, even though the distinction of these two subspecies are mostly by their geographical distribution. In this context, we described a comparative compositional and functional characterization of individual C. d. collilineatus and C. d. terrificus venoms from three Brazilian states. Methods: We compared the compositional patterns of C. d. terrificus and C. d. collilineatus individual venoms by 1-DE and RP-HPLC. For functional analyzes, the enzymatic activities of PLA2, LAAO, and coagulant activity were evaluated. Finally, the immunorecognition of venom toxins by the crotalic antivenom produced at Butantan Institute was evaluated using Western blotting. Results: The protein profile of individual venoms from C. d. collilineatus and C. d. terrificus showed a comparable overall composition, despite some intraspecific variation, especially regarding crotamine and LAAO. Interestingly, HPLC analysis showed a geographic pattern concerning PLA2. In addition, a remarkable intraspecific variation was also observed in PLA2, LAAO and coagulant activities. The immunorecognition pattern of individual venoms from C. d. collilineatus and C. d. terrificus by crotalic antivenom produced at Butantan Institute was similar. Conclusions: The results highlighted the individual variability among the venoms of C. durissus ssp. specimens. Importantly, our data point to a geographical variation of C. durissus ssp. venom profile, regardless of the subspecies, as evidenced by PLA2 isoforms complexity, which may explain the increase in venom neurotoxicity from Northeastern through Southern Brazil reported for the species.

Abstract: The aim of this study was to evaluate the effects of subcutaneous calcium administration in post-partum dairy cows with respect to carbohydrate, protein and lipids metabolism, as well as its effects on milk composition. Twenty post-partum dairy cows were randomly divided into two groups (n=10): a control and a treated group with a single dose (150 mL) of calcium. Blood collection was performed on post-partum days 1, 2, 3, 7 and 10. In addition, we measured serum levels of total calcium, total proteins, albumin, globulins, glucose, cholesterol, triglycerides, as well as creatine kinase (CK) activity. We determined milk composition on post-partum days 5, 10 and 20. Serum total calcium levels was higher on post-partum days 3 and 7 in the treated group. Serum urea (day 3) and triglycerides (days 7 and 10) levels were higher in the treated group, as were CK activity levels at post-partum days 2 and 3. Serum glucose and cholesterol levels were lower on post-partum day 2 in treated animals. Fat (day 20) and lactose (day 10) content in milk samples were higher than in the treated animals. We concluded that treatment with calcium in cows during the post-partum period changes biochemical variables related to metabolism.

Abstract Legume silage can increase the forage quality of the diets as well as supply it with nitrogen, calcium and phosphorus. The objective was to evaluate the intake, apparent digestibility, rumen fermentation and nitrogen efficiency in sheep fed a tropical legume silage with or without concentrate. Twelve crossbred sheep with an average initial body weight of 32.2 ± 1.26 kg, with six animals cannulated in the rumen were distributed into four 3 × 3 Latin squares. The treatments were 1) Stylosanthes silage without concentrate (StS), 2) Stylosanthes silage with concentrate (StS+C), and 3) corn silage with concentrate (CS+C). StS diet showed lowest intake, except for neutral detergent fiber (NDF). The diets StS+C and CS+C showed similar intake of dry matter (DM) and crude protein. The intake of total digestible nutrients was higher for CS+C diet than diets StS+C and StS. Animals fed CS+C diet had lowest ruminal pH. The nitrogen use efficiency was similar for the diets with concentrate. In conclusion, StS+C diet replacing CS+C diet decreases the intake of total digestible nutrients.

RESUMO A associação ectomicorrízica beneficia as plantas ao proporcionar aumento na área de absorção radicular obtendo mais nutrientes e água, podendo possibilitar o crescimento do hospedeiro em solos submetido a condições adversas. O objetivo deste trabalho foi avaliar o efeito de diferentes isolados ectomicorrízicos no crescimento das mudas de Eucalyptus grandis W. Hill ex Maid., Corymbia citriodora (Hook.) K.D. Hill & L.A.S. Johnson, Eucalyptus saligna Sm. e Eucalyptus dunnii Maiden. O delineamento foi inteiramente casualizado em arranjo fatorial (4 x 4), sendo quatro espécies de eucalipto (Eucalyptus grandis, Corymbia citriodora, Eucalyptus saligna e Eucalyptus dunnii) e quatro inóculos ectomicorrízicos (UFSC-Pt116 (Pisolithus microcarpus (Cooke & Massee) Cunn), UFSC-132 (Pisolithus tinctorius (Pers.) Coker & Couch), UFSC-121, e sem inoculação), com 12 repetições. Após noventa dias de condução do experimento foram avaliados: percentual de colonização ectomicorrízica, altura de planta; diâmetro do colo; número de folhas; massa seca da parte aérea e radicular. Também foram calculadas as relações: massa seca aérea/massa seca radicular, altura/diâmetro do colo e o índice de qualidade de Dickson. A altura de planta, número de folhas e a massa seca aérea apresentaram médias superiores nas espécies Eucalyptus dunnii e Corymbia citriodora, quando na inoculação com UFSC-132. A inoculação com UFSC-Pt116 resultou em 63,3% de raízes colonizadas em Corymbia citriodora, enquanto Eucalyptus dunnii inoculado com UFSC-121 teve 67,7% de suas raízes colonizadas. O isolado UFSC-132 proporciona maior crescimento de mudas de Eucalyptus dunnii e Corymbia citriodora em relação à testemunha sem inoculação.
ABSTRACT The ectomycorrhizal association benefit plants by providing an increase in the area of root absorption and getting more nutrients and water as well as may enable growth of the host soils subjected to adverse conditions. The objective of this study was to evaluate the effect of different ectomycorrhizal isolates on seedling growth of Eucalyptus grandis W. Hill ex Maid., Corymbia citriodora (Hook.) K. D. Hill & L.A.S. Johnson, Eucalyptus saligna Sm. and Eucalyptus dunnii Maiden. The design was completely randomized in a factorial arrangement (4 x 4), four species of Eucalyptus (Eucalyptus grandis, Corymbia citriodora, Eucalyptus saligna and Eucalyptus dunnii) and four ectomycorrhizal inoculum (UFSC - Pt116 (Pisolithus microcarpus (Cooke & Massee) Cunn), UFSC -132 (Pisolithus tinctorius (Pers.) Coker & Couch), UFSC -121, and without inoculation) with 12 repetitions. After ninety days of conducting the experiment were evaluated: the percentage of ectomycorrhizal colonization, plant height, stem diameter, number of leaves, dry weight of root and shoot. Relationships were also calculated: dry aerial/root dry mass, height/diameter and Dickson quality index. The plant height, leaf number and shoot dry mass showed higher average in the species Eucalyptus dunnii and Corymbia citriodora, when the inoculation with UFSC -132. Inoculation with UFSC-Pt116 resulted in 63,3 % of colonized roots in Corymbia citriodora, while Eucalyptus dunnii inoculated with UFSC-121 had 67,7 % of its colonized roots. The isolated UFSC-132 provides enhanced growth of seedlings of Eucalyptus dunnii and Corymbia citriodora compared to the control without inoculation.

ABSTRACT The aim of this work was to determine the persistence of auxinic herbicides applied on tropical pasture and toxicity for succeeding crops. The herbicides were applied in an area of dystrophic red‒yellow latosol with pasture infested of weeds. At 40, 80, and 280 days after application of herbicide, the soil samples were collected at depths of 0 to 20 cm. Soil with residues of 2,4-D, 2,4-D + picloram, triclopyr, and a soil without herbicide application were analyzed with six replicates. Seven crops were cultivated in these soils: cucumber (Cucumis sativus L.), velvet bean [Mucuna pruriens (L.) DC.], pigeon pea [Cajanus cajan (L.) Millsp.], alfalfa (Medicago sativa L.), lablab bean [Lablab purpureus (L.) Sweet], corn (Zea mays L.), and sorghum [Sorghum bicolor (L.) Moench]. The plants of cucumber, pigeon pea, and alfalfa were the most susceptible to the auxinic herbicide residues. However, the lablab bean was the only one among the dicot evaluated that showed tolerance to the 2,4-D + picloram residual when cultivated in soils at 280 days after application of herbicide. Corn and sorghum showed lower chlorophyll content in soils with 2,4-D + picloram residual up to 80 days after application of herbicide.
