ABSTRACT - The aim of this study was to evaluate the occurrence of weeds in flooded rice areas, as a function of planting system and herbicide programmes in the previous cropping year. The experiment was installed in field conditions, in randomized complete blocks design, arranged in factorial scheme 3 x 2, with eight replications. In factor A, treatments consisted on conventional tillage, minimum tillage and no till cropping systems, coupled to the application (traditional control) or not (semiecological system) of herbicides (Factor B). One year after rice cultivation, preceding the planting of the next cropping season, phytosociological evaluations of the weed communities present in the treatments were carried out. We assessed the overall infestation level and weed species composition, which were classified by their respective density, frequency and dominance abilities. We also estimated the diversity coefficients of Simpson and Shannon Weiner, and the sustainability coefficient of Shannon; treatments were also grouped by similarity in weed species composition. Rice growing systems (traditional or semi-ecological) promote remarkable differences in weed occurrence. Herbicide-based crops select specific companion weed species, but crop rotation or winter cover crops are not a sine qua non condition for success since a good herbicide programme is planned. For the Semi ecological system, crop rotation, thick winter soil mulching and association with animal presence and grazing are essential for the short, medium and long-term inhibition of weeds. RESUMO - O objetivo deste trabalho foi avaliar a ocorrência de plantas daninhas em arroz irrigado por inundação, em função do sistema de plantio e do manejo de herbicidas na safra anterior. O experimento foi instalado em campo, em delineamento experimental de blocos casualizados dispostos em esquema fatorial 3 x 2, com oito repetições. O fator A foi o sistema de cultivo, sendo sistema convencional, cultivo mínimo ou plantio direto, associados à aplicação (manejo tradicional) ou não (sistema semiecológico) de herbicidas (Fator B). Um ano após o cultivo do arroz, precedendo o novo plantio, foram efetuadas as avaliações fitossociológicas das comunidades infestantes. Foram avaliadas a infestação geral e a composição de espécies infestantes nos tratamentos, que foram classificadas pela sua densidade, frequência e dominância relativas de ocorrência. Foram ainda estimados os coeficientes de diversidade de Simpson e Shannon Weiner, bem como a sustentabilidade de Shannon; os tratamentos foram agrupados pela similaridade de ocorrência das espécies infestantes. Os sistemas de cultivo de arroz (tradicional ou semiecológico) promovem diferenças marcantes na ocorrência de plantas daninhas. O controle com base em herbicidas seleciona plantas companheiras específicas, mas a rotação de culturas ou coberturas de inverno não parece ser condição sine qua non para o sucesso desses sistemas, desde que o programa de manejo herbicida seja adequado. Para o sistema semiecológico, a rotação de culturas e espessa camada vegetal de cobertura de inverno, bem como sua associação com o pastejo animal, parecem essenciais para o manejo de plantas daninhas no curto, médio e longo prazos.

Jabuticaba is a Brazilian berry known for its therapeutic potential against cancer, obesity, insulin resistance (IR), and others. It is a natural source of bioactive compounds, leading to better glucose metabolism, and attenuating obesity and IR through the reduction of pro-inflammatory status. The present study aimed to observe the prebiotic effect of freeze-dried jabuticaba peel (J) consumption on gut bacteria profile and describe its effects on IR derived from the lipopolysaccharides/Toll-like receptor-4 inflammatory pathway. Jabuticaba peel was chemically characterized, and its bioactive compounds were quantified. Twenty-four C57BL/6 mice were feed with a control diet (n = 6), control diet + J (n = 6), high-fat diet (HF) (n = 6), and HF + J (n = 6) for thirteen weeks. Gut bacteriota (16s RNA sequencing), glucose metabolism (fasting glucose and insulin, OGTT, ITT, HOMA-IR, and β, QUICKI), and inflammatory status (serum lipopolysaccharide, and protein expression) were assessed. The main bioactive compounds found in J were dietary fiber, and anthocyanins, and its consumption along with a healthy diet reduced the abundance of Firmicutes and Actinobacteriota phyla (p < 0.01), increased the Muribaculaceae and Lachnospiraceae families, and Faecalicatena genus (p < 0.05). The correlation test indicates a negative correlation between the Muribaculaceae and glucose metabolism. Jabuticaba peel is a nutritive source of bioactive compounds with prebiotic effects. |
