| O jambu (Acmella oleracea L.) é uma das principais hortaliças cultivadas na região Norte do Brasil. Incidência de 60% a 100% de plantas de jambu apresentando sintomas de manchas anelares, necroses e manchas cloróticas, com evidências de perda em produtividade, foi observada em plantios comerciais no município de Santa Izabel, PA. Amostras foliares foram coletadas e processadas em testes biológicos, morfológicos e moleculares para a identificação do agente causal. Inoculações mecânicas de extratos de folhas sintomáticas de jambu reproduziram sintomas similares em jambu cultivar Nazaré. Exames ao microscópio eletrônico de transmissão de secções de folhas de jambu sintomáticas indicaram efeitos citopáticos típicos de infecção por orthotospovírus. RT-PCR com... |

| Abstract The aim of this study was to evaluate the microbiological and sensory quality of the Jambu (Acmella oleracea L.) in natura and dried by cold air, and the determination of its drying curve. The microbiological analysis were performed to Salmonella spp, the coagulase-positive Staphylococcus, and coliforms in the both Jambu samples, at 45 °C. Tacacá, the typical food dish of Pará state, Brazil, has showed good consumer global acceptance in the sensory evaluation of Jambu in natura (score of 8.00 ± 1.46) and dried (score of 8.67 ± 0.66). Both samples, Jambu in natura and dried by cold air, were by the current legislation regarding the microbiological aspects, this is the absence of Salmonella spp, coagulase-positive Staphylococcus <1×101 CFU/g, and... |

| ABSTRACT The objective was to evaluate the physical characteristics and physiological behavior of A. oleracea seeds during imbibition and germination, under different temperatures and photoperiods, as well as to determine the duration of the germination test. For this, biometric parameters (length, width and thickness) were measured in 100 seeds and thousand-seed weight was determined. In addition, the external structures of seeds and seedlings were described and the imbibition curve was monitored. Subsequently, the germination test was conducted at temperatures of 20, 25, 30, 35, 20-30 and 25-35 ºC, under constant and alternating light and dark photoperiods (12 h), arranged in 6 x 3 factorial scheme, with four replicates of 50 seeds. Seeds were sown in... |
