Vermiculite and shading in the formation of 'Rangpur' lime rootstock

‘Rangpur’ lime (Citrus limonia Osbeck cv. Cravo) is widely used as a rootstock for citrus seedlings, although factors such as luminosity and substrate composition are extremely important to obtain quality seedlings. The objective of this study was to analyze the formation of ‘Rangpur’ lime seedlings grown in different substrates and luminosities. A 3x4 factorial arrangement was used in an RBD with four replications of twelve plants. Three luminosities (full sun, 35%, and 70% shading) and four substrate: vermiculite proportions were tested (S1-1: 0, S2-2: 1, S3-1: 2, and S4-0: 1). The seeds were sown in 280 cm3 tubes and emergence was evaluated every two days for 30 days, and biometric assessments at 30, 60, 90, and 120 DAE by measuring the height, diameter, leaves, and mortality. Root length and shoot and root dry mass were measured at 30 and 120 days. Seeds in full sun showed high ESI values and a shorter time period, as well as high mortality at 120 DAE. Highly shaded environments cause etiolation and reduce biomass accumulation and the DQI. Seeds in S4 showed lower results for most variables. It is recommended to use 35% shading associated with the substrate proportions S1, S2, and S3.‘Rangpur’ lime (Citrus limonia Osbeck cv.

Objetivou-se com este trabalho avaliar o estresse hídrico, salino e curva de embebição em sementes de beterraba. O trabalho foi conduzido no Laboratório de Análise de Sementes do Departamento de Produção Vegetal do Centro de Ciências Agrárias da Universidade Federal do Espírito Santo (CCA-UFES), localizado em Alegre-ES. Foram utilizadas sementes de beterraba (Beta vulgaris L.) cultivar Maravilha Top Tall Early Wonder (Feltrin sementes). Para o estudo do estresse hídrico e salino as sementes foram distribuídas em rolos de papel tipo germitest, umedecidas na proporção de 2,5 vezes a massa do papel nas seguintes soluções: cloreto de sódio (NaCl), cloreto de potássio (KCl), manitol e polietilenoglicol (PEG-6000) com potenciais osmóticos 0,0; -0,4; -0,8 e -1,4 MPa mantidas em Mangelsdorff sob temperatura de 20 ºC e fotoperíodo de 12 horas. Foram avaliados porcentagem e índice de velocidade de germinação, comprimento da parte aérea e radicular e a massa fresca e seca das plântulas. O teste de embebição foi conduzido em Mangelsdorff sob mesma metodologia do estresse hídrico e salino sendo as sementes distribuídas em placas de Petri forradas com papel tipo germitest. O estresse salino e hídrico são prejudiciais à germinação e ao vigor de sementes de beterraba, sendo o estresse hídrico induzido com PEG o mais prejudicial. As curvas de embebição apresentaram claramente a resposta dos sais no processo de absorção de água com diferentes potenciais osmóticos

Reinfecção da Covid-19 em neonatos e crianças: revisão de literatura : Reinfection of Covid-19 in neonates and children: literature review

Em dezembro de 2019, um novo vírus respiratório foi detectado na China, sendo denominado posteriormente como COVID-19, provindo do vírus SARS-CoV-2. Este vírus se espalhou rapidamente gerando uma pandemia mundial. Vários foram e ainda são os problemas decorrentes deste vírus, que atingiu desde crianças aos idosos, dentre eles, cita-se a reinfeção dos indivíduos, causando como consequência, problemas de saúde inacabáveis. Assim, devido aos estudos elencarem menores sinais e sintomas nas crianças e, ainda, menores taxas de infecção, passou-se a questionar quanto as reinfecções em crianças e neonatos. Por isso, o estudo objetivou realizar uma revisão de literatura sobre reinfecção de COVID-19 em crianças e neonatos. Para isso, realizou-se uma revisão sistemática de literatura, através de uma busca nas bases de dados Latino-Americana e do Caribe em Ciências da Saúde, Google Scholar e Scientific Electronic Library Online, utilizando-se os descritores: Reinfecção COVID-19; Reinfecção COVID-19 em crianças; Reinfecção COVID-19 em neonatos; COVID-19 e reinfecção. Com isso, foram selecionados 10 artigos que compunham os critérios de inclusão e exclusão do presente estudo. Dessa forma, destaca-se que os estudos evidenciaram que o número de reinfecções em crianças e neonatos é baixo, porém, são escassas as literaturas sobre o tema, possuindo, assim diversas lacunas a serem sanadas para uma compreensão melhor do assunto

Bean seeds under salt stress as a function of nitric oxide

795-801The objective of this study was to evaluate the bean seeds under salt stress as a function of nitric oxide (NO). Four bean genotypes (Phaseolus vulgaris L.) seeds G1 = peanut; G2 = white carioca; G3 = red carioca and G4 = black that were previously immersed in four sildenafil citrate concentrations: 0; 25; 50 and 75 mg L-1 for 120 min, and placed to germinate under induced stress with NaCl at -0.8 MPa, on a germitest paper roll. The design was completely randomized, with four replicates per treatment and for the effect of sildenafil citrate concentrations, the data were submitted to regression analysis. Salinity stress with sodium chloride at -0.8 MPa reduces bean genotypes germination and seed vigor. Sildenafil citrate at a concentration of 50 mg L-1 reduced the effect of salinity stress on bean genotypes, and G1 and G3 showed a greater response under salinity stress with sodium chloride at -0.8 MPa
